Trong một hội thảo về các phân tích được thực hiện trên các thành phần thức ăn và thức ăn thô hiện tại, Alltech đã nêu ra một số rủi ro tiềm ẩn đối với nguồn nguyên liệu thức ăn đang phát triển như một phần của cách giải quyết những thất thoát của mùa màng do những vấn đề độc tố nấm mốc.
Ông Max Hawkins chuyên gia về độc tố nấm mốc của Alltech cho biết rằng, các mối nguy cơ mà ngành nông nghiệp đang phải đối mặt về độc tố nấm mốc đang trở nên phức tạp hơn bao giờ hết. Ông cũng giải thích rằng các tác động tiềm tàng từ việc thay đổi thời tiết khiến cho việc thu hoạch nông sản bị dời khỏi lịch trình quen thuộc, là điều kiện lý tưởng của độc tố nấm mốc.
Max Hawkins, chuyên gia về độc tố nấm mốc
Các nhà sản xuất cần biết họ đang ở đâu và những gì đang hiện diện trong thức ăn chăn nuôi hiện tại, ông nói. Khi mùa vụ thu hoạch đang tới gần, chúng ta sẽ biết nhiều hơn về những gì chúng ta phải đối mặt.
Những thách thức hiện tại
Các mẫu ngô đã được phân tích từ tháng 1 đã cho thấy khoảng bảy loại độc tố trong mỗi mẫu, điều này hơi đặc biệt, Hawkins nói. Nhiều nguy cơ đến từ độc tố nấm mốc trong họ Deoxynivalenol (DON) cùng với Fumonisin và Axit Fusaric.
Tuy nhiên, đã có một số rủi ro từ độc tố nấm mốc như như Aflatoxin, Citrinin, Trichothecenes B, A và Zearalenone, ông nói. Ở một số vùng của Hoa Kỳ, Penicillium, Aspergillus và Ergot cũng đã bắt đầu xuất hiện. “Những giá trị rủi ro cao hơn đang xuất hiện ở ngoài kia, và có thể bên trong thùng thức ăn, đang chực chờ tấn công đàn vật nuôi” – Ông nói.
Thành phần thức ăn có thể gây rủi ro cao cho bò sữa và bò thịt, tuy nhiên, trộn ngô vào khẩu phần hỗn hợp sẽ làm giảm nguy cơ. Đối với heo, có nhiều nguy cơ khác nhau hơn. Chúng có nguy cơ cao đến từ DON, từ Fumonisins và Zearalenone, vì vậy chúng có thể ảnh hưởng đến tất cả các giai đoạn sản xuất, lợn nái, vỗ béo và xuất chuồng, ông nói. Tuy nhiên, đó sẽ là một rủi ro cao trên toàn bộ quy trình. Sẽ có một số rủi ro thấp, nhưng nhìn chung, rủi ro vẫn là rất cao.
Gà đẻ cũng được dự báo là sẽ đối mặt một số rủi ro từ DON và Fumonisin, trộn ngô vào khẩu phần sẽ tạo ra thức ăn có rủi ro trung bình hoặc cao hơn một chút. Sẽ có rủi ro thấp hơn cho gà thịt và nguy cơ cao hơn đối với chim non trong chế độ ăn trong những ngày đầu. Tuy nhiên, nguy cơ nhìn chung là cao hơn so với trước đây.
Các mẫu thân bắp ủ chua (Corn Silage) cũng cho thấy nhiều độc tố nấm mốc hơn trước đây - khoảng sáu mỗi mẫu, Hawkins nói. Nguy cơ có xu hướng đến từ DON và Fumonisin, Axit Fusaric và Penicillium, và thách thức đang ngày một cao hơn.
Thân bắp ngô ủ chua, một nguyên liệu đang bị độc tố nấm mốc tấn công
Thức ăn ủ chua có nguy cơ từ bằng đến cao hơn một chút đối với bò sữa, ông nói. “Bên cạnh đó, nếu ta nhìn vào thực tế là từ đầu năm đến nay, nguy cơ này luôn hiển diện. Tôi không nghĩ sẽ có gì thay đổi trừ khi chúng ta có một nguyên liệu thức ăn mới hoàn toàn”.
Những thách thức trong mùa thu
Mùa xuân ẩm ướt làm trì hoãn việc trồng bắp nhưng một số phần của Vành đai bắp ngô đã bắt đầu khô cạn , Hawkins nhận xét.
“Nếu chúng ta nhìn vào phần trăm lượng mưa bình thường, Đồng bằng Bắc Bộ đã ẩm ướt nhưng từ phía đông Iowa, miền bắc Illinois, trên khắp Indiana và vào Ohio, nó đã khô như ở Đồng bằng Nam”, ông nói. “Những khu vực này đã khô cạn đến mức bây giờ nếu bạn nhìn vào màn hình hạn hán bạn sẽ thấy khu vực đó từ phía đông Iowa, miền bắc Illinois, đến Indiana và Ohio bắt đầu xuất hiện những khu vực căng thẳng trên màn hình hạn hán”.
Vụ ngô, đặc biệt là bắp ngô trồng muộn, cũng đang bắt đầu bị ảnh hưởng ở một số vùng đó, ông nói. Các tác nhân gây nên sự căn thẳng cao mang đến nguy cơ một số độc tố nấm mốc phát triển bao gồm độc tố Fusarium, DON, HT2, Zearalenone trong bắp ngô trồng muộn và các vấn đề như Aspergillus và Fumonisin ở các khu vực khô cạn hơn.
Cũng có nguy cơ độc tố Ergot ở một phần của đất nước, như Bắc và Nam Dakota, nơi thời tiết mát mẻ và ẩm ướt. Các độc tố Ergot đặc biệt có vấn đề với thức ăn thô hạt nhỏ đã được thu hoạch để ủ chua. Rất nhiều công ty sữa và một số nguyên liệu đang hết thức ăn, họ đã phải đến những khu vực ủ hạt nhỏ có Ergot cao và họ thực sự không sẵn sàng để đối đầu với các nguy cơ ấy. Và vì thế, các vấn đề tiềm ẩn bắt đầu hiện ra.
Độc tố nấm mốc – vấn đề không thể xem thường
Tuy nhiên, các mẫu ngô ủ ban đầu từ Florida xuất hiện phù hợp với những gì đã được tạo ra trước đó, ông nói. Tuy nhiên, khi bạn rời khỏi Florida và bắt đầu di chuyển về phía bắc qua Georgia, đã có rất nhiều bắp ngô bị hạn hán và khi bạn di chuyển xa hơn về phía bắc, bạn sẽ bắt gặp hoặc bắp ngô thật sự khô, hoặc thật sự ướt.
Không có nhiều thông tin về tỷ lệ mắc bệnh ngô như bệnh đốm lá hoặc bệnh cháy lá, nhưng nhiều thông tin dự kiến trong vài tuần tới, ông nói.
“Một điều khác mà chúng tôi cũng muốn quan tâm là thiệt hại do mưa đá”, Hawkins nói. Nó có thể là tiền thân rất lớn của Fusarium, DON, T2 và những thứ đó - nếu nó không đủ xấu để quét sạch bắp ngô, nó vẫn có thể đủ đáng kể để gây thương tích nghiêm trọng cho cây và khiến nó dễ bị nhiễm nấm mốc hơn.
Trong tương lai, các nhà sản xuất nên nhận thức được các điều kiện trong khu vực nơi họ cung cấp nguyên liệu thức ăn hoặc thức ăn ủ chua của họ, ông nói.
With the rise of foreign animal diseases like African swine fever, mitigating the risk of viruses spreading through feed has become a massive challenge for pig producers today. Dr. Gordon Spronk and Dr. Jon De Jong of Pipestone System detail their research on biosecurity measures in feed to reduce risk on farm.
The following is an edited transcript of Kara Keeton's interview with Dr. Gordon Spronk and Dr. Jon De Jong. Click below to hear the full audio.
Kara: I'm here today with Dr. Gordon Spronk and Dr. Jon De Jong with Pipestone, and we're going to talk today about animal nutrition and health. Gentlemen, thank you for joining me today.
Gordon: You're welcome. Thank you for inviting us to be here.
Kara: Lovely. Give me the lay of the land right now. We know biosecurity issues are a massive challenge for pig producers at this time. What diseases are most prevalent and where are they impacting pigs on a global scale?
Gordon: Well, thanks for the question. In pig production, the healthiest pigs grow the fastest and make the most money for their owner, our farmer producers. Biosecurity — sometimes, we make it too complicated, when, at its simplest, we want farms that produce pigs that don't have viruses and that don't have bacteria.
Specifically, there are a number of viruses in our North American herd that we've successfully either eliminated or kept out. There's some rise with African swine fever, which is the hot topic right now, foot and mouth disease, hog cholera and pseudorabies. Those four viruses are all classified as foreign animal diseases. We do not have those four viruses in the North American herd, and we hope to keep them out of our North American herd for the benefit of not only our pig farmers but all of agriculture.
Kara: We were talking about African swine fever and biosecurity on the farm. How does feed and biosecurity play on the farm?
Jon: Pipestone has been active in biosecurity interventions ever since I was a graduate in 1981, where, at that time, we washed our boots before we went to a farm. Well, from that day to this day, there's a lot of things we do at a farm to prevent disease or pathogen entrance. Today, we filter farms. We spend millions of dollars on HEPA filters to prevent virus introduction to a farm. All employees shower in. We wash all our trucks. We dry all our trucks. We make sure that all the supplies that are delivered to the farm are delivered from a biosecure warehouse and are quarantined on the farm.
The point is we have many steps already that we've taken with biosecurity. Now, we're just simply adding feed to this biosecurity portfolio. Because, before PED in 2013, it was never even considered as a potential risk to the farm. So, we're very excited that we continue to add preventative measures, add interventions that are a part of biosecurity to a farm to make our farmers more money and our pigs healthier.
Kara: You're co-founder of the Pipestone system, a pig production. What is that? As well, what is the role of Pipestone in the swine industry?
Gordon: Sure. Well, at Pipestone, we're active in four areas. We're active in animal health, we're active in nutrition. That's why Jon is here today. We're active in management, and we're active in marketing.
The management part is, 30 years ago, we started managing sow farms for farmers. They wanted a source of weaned pigs; we had the ability to help them meet that need by not only building and designing and running farms, but also going through the whole process of stocking the farm and making sure that, even at the disease level, we stocked the farm with the viruses we just talked about. We've been active in that space for 30 years in meeting the direct need of our farmer owners.
Kara: So, the biosecurity issues are not new to Pipestone.
Gordon: There's nothing new here. We learned long ago that keeping viruses out made our farmers more money. So, biosecurity is all about keeping viruses and bacteria out.
Kara: And keeping the farmers happy and the pigs healthy.
Gordon: Well, our mission statement is “helping farmers today create the farms of tomorrow.” Well, the farm of tomorrow may not have those viruses or those bacteria so that their pigs are healthier.
Kara: Exactly. That is wonderful. Now, recently, you have collaborated with Alltech on a new set of research and products and development initiatives. Why was that important to you, and what new opportunities does Alltech bring to the table for Pipestone?
Gordon: Yeah, I'm going to turn it over to Jon here in just a second. If you look at the whole portfolio of protecting a farm with biosecurity, until 2013, feed was not part of that formula, not part of that thought process. Well, PED taught us that maybe that virus is moving around in other ways that we normally would have put interventions in place. In other words, it could have been coming through feed or feed ingredients. That PED experience then also allowed us to make observations in China, because we're active in China, so we know how that virus is moving around in the field. That led us to say that, “Listen, maybe we should put interventions in place in feed,” and that's where I'll turn it over to Jon, as a nutritionist, to help explain that intervention in feed to prevent the movement of virus in feed and feed ingredients.
Jon: Yeah, thank you, Gordon. Just like Gordon mentioned, for 20 or 40 or 50 years, we've fine-tuned and worked on the biosecurity measures at our farms, and really, the final piece that we think was missing was the feed. PED taught us a lot in 2014. We realized that virus can transmit itself via the feed, and, at the time, we weren't doing a single thing about it.
So, at that point, Pipestone, with our research team and Dr. Scott Dee, took it upon ourselves to, one, understand: is feed a vector for virus? And, as Scott proved very quickly, that, yes, we can infect pigs with virus through the feed. And then the second part was, okay, we know the virus can infect pigs when you feed it to them. Now, how do we stop it? So that's taken on a whole ’nother world for the Pipestone system and a lot of other researchers in the U.S. today, is how do we stop viruses from either, one, getting into the feed, or, once they get into the feed, how do we mitigate them and stop them from infecting pigs?
That's where we started working with a number of products. One we developed ourselves called APC, that product, we spent the last three or four years researching, trying to develop it, understand the inclusion rates and make sure that the product was efficacious against the viruses that we knew of at the time, PEDv. And then, for the first time ever, we were able to show that PRRS, typically known as an aerosolized virus — we filter our farms, filter the air that goes in them, specifically because of that one virus — but Dr. Dee was able to prove and show for the first time ever that it can have transmission in the feed as well. So, we know that the product, the APC, now is capable of mitigating both PEDv and PRRS in the feed.
Kara: Now, the product again that you mentioned, what exactly is it?
Jon: APC.
Kara: APC. What exactly is that product?
Jon: Yeah, so APC is a blend of different products, mainly organic acids with some essential oils blended with it, a product that's shown over a number of research trials, both in the lab as well in a bioassay setting, where we actually feed the virus to the pigs. We've shown over a number of studies that it's a product capable of mitigating the effect of viruses in feed.
Kara: That's amazing. What other new technologies are you working on with Alltech and on your own at Pipestone that can help ensure that the quality of feed and the feed ingredients are at the quality they need to be for the swine operations and to help mitigate virus issues?
Jon: Yeah, absolutely. One, we want to work with Alltech to make sure that the product they've acquired from us, APC, is up to snuff, that it continues to be the most researched product in the market. And then, on top of that, not only can we mitigate feed, but there's a number of other steps that we can take. So, I think Pipestone has really tried to lead the way in the industry in terms of, how are we bringing in, specifically, ingredients from countries that have virus in them? We know for a fact today that a lot of our feed ingredients — amino acids, vitamins and trace minerals — they come from countries that are infected with ASF. That's, for us, a huge concern.
I would say (that there was) no smoking gun in 2014 that PEDv was brought in on feed ingredients. But our group would say there was some substantial evidence that would point us in that direction. So, really, Dr. Dee and our team has just poured into the research over the last six months, really, since the outbreak was mentioned or happened in China, and really needed to validate three things. One, can ASF survive in feed ingredients during the importation process? Does it survive the trip over the ocean? That was step one, and we were able to show, along with a number of other viruses, that a lot of those viruses will survive the journey in a feed ingredient like amino acids or soybean meal. So, step one, yep, check. The virus survives the trip across the Pacific to Des Moines. That was part of Scott's transboundary research that he conducted last year.
The second step, which Kansas State was able to find out here very recently, in the last 60 days, is when the virus is in feed and you feed it to pigs, do they become infected? And what is the minimum infectious dose? So, Kansas State was able to now show that, yup, if you put the virus in the feed or the virus is present in the feed, you feed it to pigs, they can become infected with African swine fever. Really, we've been able to complete that loop of, yes, there's virus present in China, where we know we import a lot of ingredients; yes, it survives the trip across the Pacific; and yes, if it would get to a pig, that it can become infected. So, really, just going through and validating those three things were very important to us.
The last thing we've been able to do is, working with SHIC and the AFIA, is to understand, okay, if we bring an ingredient into the U.S., how long do we need to keep it in quarantine before it may be safe to feed to the pigs? Still working through those exact numbers; I know there's some time periods that are out there. I think more time is better. When you're dealing with viruses and bacteria, time is on your side. So, quarantining those ingredients for longer periods of time is, we know, going to be a good thing.
Kara: So, there is hope that you can kill the virus by putting it in quarantine for a certain period.
Jon: Yeah, and Gordon and I were just talking about this this morning. There are three things we've really done. One, you have to make sourcing decisions. Where are you going to source your ingredients from? And, at the end of the day, price is king to a lot of folks, and so we still end up bringing some ingredients in. You can only get certain ingredients from countries infected with ASF. So, one, you can make sourcing changes or decisions.
The second thing is, okay, let's quarantine those ingredients when we get them to the U.S. And then the third thing is mitigation. What can we add to the feed as a last step of defense to protect those pigs from getting infected?
Kara: It's obvious that the swine industry will never go back to being small-scale, locally sourced feed options. So, we're going to continue to face global issues when it comes to viruses and feed sources and within the swine industry. What are the implications of new technologies to promote feed safety productions, safe pig production? Is there anything that you're working on beyond this right now that you hope to see come to fruition in the near future?
Jon: Yeah, I think a couple of things that Pipestone specifically has been working on. One is how do we responsibly import ingredients? We understand it's a global market. We're going to have to bring things across borders, both pigs and feed ingredients. How do we do that in a responsible manner? So, we're really trying to set the protocol today and implement it, and what does responsible importation look like? That's one.
The second thing in the responsible import process is, how can we verify that the things we're requesting these vendors and suppliers do, how can we verify that they're actually getting done? The potential to certify certain suppliers, distributors, blenders to make sure that we are what we call responsible, doing things the right way when those products are coming into the U.S.
Kara: So, it is wonderful to have companies like Pipestone be proactive in this effort and continue the work in research. Do you see this being, long-term, biosecurity being a major issue for Pipestone in the future and as changes continue in the industry?
Gordon: I think it's an opportunity for both Pipestone and Alltech, and we're very pleased to be partnering with Alltech on a product like this, that the feed industry is embracing what, prior to PED, no one — including veterinarians, owners and the feed industry — did not think feed was a risk. And now, it's being recognized as not only a risk, but now, we need to put interventions in place to either mitigate that risk or just take it out completely.
So, I'm very pleased in that the future is bright as we do more and more research. I think we're just scratching the surface of what can be done in this area to not only impact the feed safety, to have healthier pigs, but also to impact in nutritional content so that these pigs grow faster and make more money for our farmer owners.
Kara: This research and development is not just limited to the swine industry. This carries over to other industries.
Gordon: It could impact other species. Right.
Jon: Absolutely. And just like Gordon said, I think we're truly at the tip of this iceberg in regards to feed biosecurity. We look at all the assets we have across the United States and other countries, these feed mills that we're building and have been built. The last thing on anybody's mind when we were putting these assets together was biosecurity. So, I think, all the way back to how we build the feed mills moving forward, biosecurity is going to be at least on the list, where, even five years ago, it wasn't on anyone's radar.
Kara: Well, thank you, gentlemen, for taking the time today to talk to me about Pipestone, the partnership with Alltech and nutrition and health and biosecurity in the swine industry. Again, this was Dr. Gordon Spronk and Dr. Jon De Jong with Pipestone. Thank you, gentlemen.
Gordon: Thank you.
Jon: Thank you.
Viruses from feed can infect pigs with foreign animal diseases. What can biosecurity measures can be taken to mitigate these viruses on farms?
Las úlceras, particularmente las del tipo gástrico, son uno de los temas más discutidos y debatidos fervientemente entre los propietarios de caballos en la actualidad.
¿Problemas de desempeño? Pueden ser ulceras ¿Aparecen las úlceras por una cuestión de actitud? Probablemente ¿Poco apetito? ¿Ha verificado sin hay úlceras? Lo entenderá ahora.
El síndrome de úlcera gástrica equina (SUGE) es un problema frustrante y potencialmente costoso: la gastroscopia (un examen endoscópico del estómago del caballo) y el tratamiento con omeprazol pueden costar más de $ 1,500. Y lo más increíble de todo es que las úlceras son un problema completamente creado por el hombre. Hemos interrumpido el entorno natural del caballo y su régimen de alimentación y pastoreo por nuestra propia necesidad de rutina y conveniencia. Cada una de las siguientes causas puede llevar al caballo a desarrollar úlceras, algo que todos preferimos evitar:
• Confinamiento en los establos
• Horarios prescritos para las comidas.
• Dietas con altos niveles de granos
• Mayores demandas de entrenamiento
• Competencias
• Cambios ambientales: incluyendo viajes, desplazamiento a un nuevo establo o un cambio en las dinámicas de la manada.
Tratando lo desconocido
Las úlceras gástricas son sumamente comunes en los caballos de alto rendimiento. Se estima que hasta el 90% de los caballos de carreras y el 70% de los caballos de exhibición las tienen. Sin embargo, este problema no es tan blanco y negro como parece. Si bien algunos podrían pensar que la solución es tan simple como omitir la costosa endoscopia y sumergirse en el tratamiento, solo espere hasta que el costo de las medicinas aparezca: las sondas de omeprazol no son baratas, especialmente cuando se necesitan para 28 días. Como una que ciertamente no ha nacido en cuna de oro, puedo identificarme totalmente con ello. Es posible que haya escuchado que el omeprazol en polvo es mucho más barato o que la ranitidina de venta libre (piense en Zantac®) puede resolver los problemas de su caballo por menos, pero como dice el viejo dicho “lo barato sale caro”, que especialmente encaja en esta situación.
Pero miremos esto desde otro ángulo: ¿Tomaría medicamentos, algunos realmente costosos, para algo que ni siquiera está seguro de tener realmente? Suena ilógico, ¿verdad? Si cree que su caballo tiene úlceras gástricas, llame a su veterinario para programar una gastroscopia. Es la única manera de hacer un diagnóstico definitivo.
Más vale prevenir que curar
¿Sabía que Benjamín Franklin hablaba sobre seguridad contra incendios cuando dijo: “Una onza de prevención vale tanto que una libra de cura”? Aun hoy, su sabiduría se aplica. Hacer algunos ajustes relativamente simples al estilo de vida y al horario de alimentación de su caballo, puede reducir en gran medida su riesgo de desarrollar úlceras.
Algunos simples ajustes de manejo pueden ayudar considerablemente a reducir el riesgo de que su caballo desarrolle úlceras.

La clé, c’est le mélange!
La MécaFibre400+ est idéale pour les grandes exploitations qui exigent une cadence de travail supérieure, d’une capacité, d’une durabilité et d’un fonctionnement sans problème. Elle comporte un système d’entrainement solide à 4 chaînes et présente une capacité de 10 tonnes.
Le besoin de puissance pour remorquer une mélangeuse MécaFibre400+ est un tracteur 120 chevaux. La mélangeuse lorsqu’elle est chargée, requière généralement et approximativement la moitié de cette puissance, engendrant une économie considérable sur la consommation de carburant (et souvent sur la taille du tracteur également) par rapports aux autres mélangeuses.
Les essieux suiveurs tandems sont montés en série et pour une maniabilité optimale les essieux directeurs sont optionnels (avec des essieux directeurs de 3 000 mm). Le châssis renforcé a été conçu pour améliorer le transfert de poids et la stabilité du conducteur lors de ses déplacements.
La conception du système de transmission par quatre chaînes vous assure un allongement de la durée de vie du matériel. Comment cela est possible ? Les rapports d’entraînement de chaque chaîne ont été réduits et une chaîne indépendante assure le retour entre la transmission et la vis de distribution. Les chaînes sont tendues à l’aide d’un bloc de ressorts.
Le système d’entrainement à 4 chaînes fonctionne dans un bain d’huile gardant toutes les chaines lubrifiées à leur niveau optimal de sécurité et de longévité.
L’huile est constamment transmise aux chaînes par une série de canaux placés stratégiquement et est recyclée dans le bain d’huile. Ce dernier améliore la dissipation de la chaleur et augmente la durée de vie des chaînes.
La MécaFibre400+ est équipée en série d’un système de graissage centralisé à 18 point permettant de graisser facilement et rapidement les roulements qui sont difficiles à atteindre.
La MécaFibre400+ peut être fourni avec la dernière technologie de découpe de balle entière. Les balles rondes ou carrées de fourrage, placées directement sur le berceau supérieur, sont coupées et incorporées dans la ration en un rien de temps.
Le dernier système balle entière mis au point par KEENAN représente une capacité de traiter rapidement tous types de balles et de fourrages.
La mélangeuse MécaFibre380+ est conçue pour les exploitations qui veulent alimenter un grand nombre d’animaux en peu de temps. Avec une charge utile de 9,000 kg, la machine est capable de nourrir 150 vaches laitières ou plus de 350 taurillons pendant 24 heures avec un seul chargement. Esthétiquement plus proche de la MécaFibre400+, elle se manœuvre comme la MécaFibre365+, avec certaines fonctionnalités uniques.
Comme pour toutes les mélangeuses KEENAN, la MécaFibre380+ conserve le système de mélange à pale, garantissant la production d’une ration homogène pour chaque chargement.
Les lignes tout en courbes de la MécaFibre380+ ont été étudiées pour un fonctionnement optimal du rotor qui limite le besoin en puissance. Ces lignes courbes limitent les forces exercées sur les couteaux et contre-couteaux pour une coupe nette en fibres efficaces MécaFibre™ des fourrages. La MécaFibre380+ est équipée d'un nombre de couteaux de base, qui peut être augmenté. Ils sont disposés en un double chevron pour obtenir une coupe et un mélange homogènes et réguliers.
Le principe du bain d’huile complet pour la transmission par chaîne a été retenu pour la MécaFibre400+ mais simplifié d’un point de vue de construction et de maintenance.
La transmission de la MécaFibre380+ est assurée par trois chaînes. Ce système de transmission assure la longévité de la mélangeuse : les rapports d’entraînement sont réduits pour chaque chaîne ; une chaîne indépendante réalise le retour entre la transmission et la vis de distribution. L’immersion du système de transmission dans un bain d’huile garantit une lubrification optimale des chaînes et une grande sécurité d’utilisation. L’accès au bain d’huile et à l’ensemble de la transmission se fait par deux panneaux en fibres de verre.
Le nombre de couteaux, leur configuration et leur emplacement ont été revus et optimisés. Tous les couteaux sont localisées dans le corps principal de la machine. Cela assure une coupe efficace du mélange sans augmenter les besoins en puissance.
Le dernier système balle entière mis au point par KEENAN représente une capacité de traiter rapidement tous types de balles et de fourrages.
La mélangeuse MécaFibre345+ ressemble à la KEENAN MécaFibre320+, offrant une capacité plus importante (jusqu’à 35%) et fonctionnant avec une chambre de mélange élargie. Elle dispose d’un système d’entrainement à bain d’huile permettant une lubrification automatique des chaînes pour un entretien facilité et un graissage centralisé de tous les roulements avant à partir d’un seul emplacement.
Ce système dernière génération utilise six pales tournant à une vitesse de 7 t/min. Le design des couteaux a été amélioré : le dégagement au niveau des bras a été augmenté afin d’optimiser le mélange.
La MécaFibre345+ possède un volume de mélange supérieur tout en étant compacte grâce à un corps de chargement et une chambre de distribution rabaissés permettant d’augmenter la capacité de la mélangeuse. La hauteur de distribution peut être modulée en abaissant le châssis ou en utilisant des roues de
taille différente.
La vitesse contrôlée de coupe réduit considérablement les besoins en puissance. Un tracteur 90 CV peut tout à fait être utilisé, ce qui permet d’importantes économies de carburant par rapport à d’autres mélangeuses.
Le système de transmission par deux chaînes de Keenan est d’une grande fiabilité. Une première chaîne de transmission et trois pignons transmettent la puissance au tendeur et au distributeur. Un second pignon entraîne le grand pignon des pales.
Le système d'huilage automatique est actionné par les vérins hydrauliques qui commandent l’ouverture et la fermeture de la porte guillotine. L’huile est ainsi dispensée à intervalles réguliers dans les chaînes de transmission pour une lubrification optimale, assurant un niveau maximum de sécurité et un allongement de la durée de vie du matériel.
La MécaFibre345+ peut être équipée de la nouvelle technologie de traitement de balles entières. Des balles de fourrage rondes ou carrées sont placées directement dans le réceptacle de la mélangeuse, puis sont coupées et incorporées dans la ration en quelques minutes.
La MécaFibre320+ est un modèle idéal pour les utilisateurs de taille moyenne. Conçu en tenant compte des besoins nutritionnels spécifiques des animaux, le mélange aéré et homogène réalisé en douceur par les pales produit un mélange physique optimal sans endommager la structure de la fibre.
Les pales associées à la précision des couteaux tournent à une vitesse de 7-8 t/min afin de faire remonter les aliments au sommet de la chambre de mélange avant qu’ils ne retombent, assurant ainsi un mélange doux et non agressif. Ce système garantit un mélange complet et continu de l’ensemble des ingrédients et donc une structure de ration adéquate pour une ingestion alimentaire et des performances optimales.
La MécaFibre320+ a été spécifiquement conçue pour être entretenue facilement sur l’exploitation. Cela garantie un travail optimal de la machine jour après jour. Il y a seulement 2 chaînes dans la machine et ces deux chaînes ont des capacités de charge supérieures à celles requises techniquement. Cette conception simple et fonctionnelle de l'entraînement indique l’absence de boîte de vitesse compliquée pouvant mal fonctionner. Les roulements, au nombre de six, sont montés à l’extérieur de manière à pouvoir les réparer plus facilement.
Pour la sortie, la porte guillotine s’ouvre par le bas. Les pales poussent le mélange vers la vis de distribution sur toute la longueur de la machine, permettant une sortie régulière et homogène de la ration. La porte guillotine vous permet d’ajuster la vitesse de déchargement. Elle peut être fermée lors de la sortie d’aliment ce qui permet d’ajouter des ingrédients alimentaires supplémentaires pour simplifier la distribution. Les mélangeuses peuvent être élevées pour distribuer l’alimentation dans des auges de hauteur 1184 mm.
Un système d'huilage automatique des chaînes peut être installé et fonctionné à partir des vérins hydrauliques ouvrant et fermant la porte guillotine. Cela délivre des impulsions d’huile en direction des chaînes d’entrainement ce qui permet de les lubrifier de manière optimale pour une meilleure sécurité et une meilleure durée de vie des chaînes.
La MécaFibre320+ peut être fournie avec la dernière technologie de découpe de balle entière. Les grandes balles rondes ou carrées de fourrage, placées directement sur les doigts supérieurs, sont coupées et incorporées dans la ration en quelques minutes.
Le dernier système balle entière mis au point par KEENAN traite rapidement tous types de balles et de fourrages.
La MécaFibre300+ a été spécialement conçue pour les exploitations présentant un bâtiment d’élevage avec un accès limité au niveau du couloir d’alimentation. Elle est fabriquée avec précision pour une plus grande maniabilité et emploie le nouveau système révolutionnaire de châssis 3 points.
La nouvelle conception améliorée de la mélangeuse offre une capacité plus importante pour une machine plus compacte mais aussi un nouveau design de pales donnant lieu à une action de brassage plus saine. La MécaFibre300+ conserve encore le design unique d’une double chambre séparée par un assemblage de porte à guillotine éprouvé pour faciliter une sortie rapide de l’aliment.
La puissance nécessaire pour remorquer une mélangeuse MécaFibre300+ est un tracteur 80 chevaux. La mélangeuse lorsqu’elle est chargée, requière généralement et approximativement la moitié de cette puissance, engendrant une économie considérable sur la consommation de carburant par rapports aux autres mélangeuses malgré une capacité supérieure et un débit de déchargement plus rapide.
Le nouveau châssis trois points en T dispose de barres de pesage renforcées placées directement sur l’essieu arrière et la barre d’attelage avant afin de réduire toute flexion potentielle et permettant ainsi de garantir une pesée précise. L’ensemble vous assure une plus grande maniabilité dans des environnements ou l’espace est limité.
La robuste ligne d’entrainement à 2 chaînes de la MécaFibre300+ constitue une conception KEENAN éprouvée utilisant un arbre porteur indépendant pour réduire toute charge sur les pignons d’entrainement de la vis de déchargement tout en permettant de l’entraîner à la vitesse requise pour atteindre des vitesses de déchargement rapides.
Un système d'huilage automatique peut être installé et fonctionne à partir des vérins hydrauliques ouvrant et fermant la porte guillotine. Cela délivre des impulsions d’huile en direction des chaînes d’entrainement ce qui permet de les lubrifier de manière optimale pour une meilleure sécurité et une meilleure durée de vie des chaînes.
La MécaFibre300+ peut être fournie avec la dernière technologie de découpe de balle entière. Les balles rondes ou carrées de fourrage, placées directement sur les doigts supérieurs, sont coupées et incorporées dans la ration en 90 secondes.
