Every producer knows that when a beef cow is healthy, her calf has a much better chance of being healthy, too. Trace mineral nutrition is key for maintaining healthy cattle at all life stages. Colostrum quality, calf weight and immune function are among the many benefits from supplementing organic trace minerals in cattle. A study done in 2017 at the University of Florida and published in The Professional Animal Scientist evaluated the response of 160 Angus (AN) and Brangus (BN) cows and their calves to inorganic (ING) or organic (ORG) trace mineral sources.

About the study

The purpose of the study was to evaluate the difference in performance and benefits provided by feeding organic trace minerals versus inorganic trace minerals to cattle on pasture. Beef cows supplemented with organic trace minerals received cobalt, copper, manganese and zinc in the form of Bioplex^® and selenium in the form of Sel-Plex^®. Beef cows supplemented with inorganic trace mineral products received them as sulfates and sodium selenite, respectively.

The level of mineral supplementation also varied between treatment groups:

• In the pelleted feed, the organic trace mineral treatment included 25% less copper, 13% less manganese and 29% less zinc compared to the inorganic trace mineral treatment.
• In the free-choice mineral, the organic trace mineral treatment included 45% less copper, 32% less manganese and 46% less zinc than the inorganic trace mineral treatment.

The best mineral strategy for cattle is one that fits within the producer’s operation, based on their animal requirements and budget and the benefits provided from that mineral product. Organic trace minerals, such as Bioplex and Sel-Plex, are more bioavailable and, as a result, can be added at much lower inclusion rates than the traditional inorganic sources, which not only benefits the environment but, ultimately, the health, well-being, reproductive performance and growth of the animals as well.

Effects of trace mineral source on colostrum

The University of Florida trial revealed that colostrum from lactating cows supplemented with organic trace mineral supplement sources contained 29% more immunoglobulin M (IgM mg/dL) antibodies compared to cows supplemented with inorganic trace minerals (P= 0.07). Cows supplemented with the organic trace mineral sources Bioplex and Sel-Plex also demonstrated significantly higher levels of selenium measured in colostrum —and Angus cows specifically had twice as much selenium compared to their inorganic counterparts (P ≤ 0.001).

The study results also showed that the somatic cell counts (SCC) of the colostrum from Angus cows fed organic trace minerals were 67% lower than the SCC of the colostrum from cows fed inorganic trace minerals. Additionally, Brangus cows fed organic trace minerals had 14.6% lower SCC compared to cows fed inorganic trace minerals.

Effects of maternal mineral nutrition on calf weight and antibody levels

As the study progressed, the researchers at the University of Florida observed that calves from cows fed the organic trace mineral sources (Bioplex and Sel-Plex) showed a statistically significant increase in their average daily gains, weaning weights and 205-day adjusted body weights compared to calves fed inorganic trace mineral sources (P ≤ 0.01).

Calves from cows who were supplemented with Bioplex- and Sel-Plex- had 205-day adjusted body weights that were, on average, 22 pounds heavier compared to the weights of calves from cows that were provided with inorganic sources (P ≤ 0.01). Specifically, Angus calves supplemented with Bioplex and Sel-Plex minerals were 33 pounds heavier (205-day adjusted weaning weights) compared to calves from Angus cows supplemented with inorganic trace mineral sources.

The researchers also measured immunoglobulin levels and found that the immunoglobulin A (IgA mg/dL) antibody measurements for calves from cows supplemented with organic trace minerals Bioplex and Sel-Plex demonstrated a statistically significant (40.5%) increase in calf serum 24 hours after colostrum consumption compared to calves from cows provided with inorganic trace mineral sources (P = 0.04).

Bioplex^® offers a range of trace minerals that provide mineral nutrition in a form as close to nature as possible. Bioplex minerals are trace minerals that are bound to amino acids and a range of peptides. They are easily absorbed and readily metabolized, optimizing animal performance. Bioplex trace minerals (including zinc, manganese, copper, iron and cobalt*) are co-factors in the enzymes that are critical for the animal’s defense system, growth and reproduction. Learn more about Bioplex here.

Sel-Plex^® is Alltech’s proprietary organic form of selenium yeast. It is an excellent dietary source of selenium and is manufactured to mimic the selenium found in nature. The selenium in Sel-Plex is safer and better able to meet the higher requirements of livestock raised for rapid growth, reproductive performance and health. Learn more about Sel-Plex here.

Are cattle producers ready for the impending U.S. Veterinary Feed Directive (VFD)?

More than 550 days ago, the U.S. Food and Drug Administration (FDA) announced its updated regulations for the VFD, and now, in just a few short days, the rules will go into effect. Some producers are now scrambling to get clarity on this critically important new directive.

Alltech has put together the latest information to separate fact from fiction and make sure everyone is ready to make the most of the upcoming changes. Let’s start from the beginning:

What’s the VFD, again?

The Veterinary Feed Directive, or VFD, will restrict the use of medically important antibiotics in animal feed. On Jan. 1, 2017, it will be illegal to use certain antibiotics without a veterinary prescription, and affected antibiotics will only be available to prevent, control or treat a specifically identified disease.

Functionally, it will work as follows:

• Feed companies and distributors must register with the FDA if distributing veterinary feed directive feeds.
• Veterinarians will be prescribing veterinary feed directive drugs and must have pre-existing veterinary-client-patient relationship (VCPR); more on that below.
• Veterinary feed directive prescriptions may be sent to distributors by veterinarians or by hard copy delivered by clients.
• Drug manufacturers will be allowed to assist veterinarians and feed companies with the processing.

Which drugs will be affected by the Veterinary Feed Directive?

A full list is available through the FDA website, but some of the most commonly affected drugs are listed below.

Remember, the list below shows the generic names and not brand names, so be sure to review the appropriate end products.

What worries have some producers expressed about the Veterinary Feed Directive?

The language around a “pre-existing veterinary-client-patient relationship” within the VFD can be confusing. To break that down, generally, this relationship for a producer requires:

• A veterinarian who is familiar with the producer’s operation.
• A veterinarian who will assume responsibility for making medical decisions on the animals involved.
• Medically timely visits to the premise.
• A producer who agrees to follow veterinary directions.
• A veterinarian who is available for follow-up as needed.

For additional insight, a complete list of VCPR criteria by state can be found here.

Dispelling Veterinary Feed Directive rumors: True and false facts

Information on the VFD can be found easily, but misinformation and incorrect rumors about what the VFD is can be just as common. As the start date approaches, what are the most common rumors that need to be dispelled?

Rumor: Feed-grade antibiotics are going away for good.

 That’s false. What is going away is the ability to use feed-grade antibiotics for growth promotion and other off-label uses.

Rumor: Injectable antibiotics will be banned.

That’s false. These will still be available over the counter as needed.

Rumor: The VFD will affect both small and large producers.

That’s true: Large or small, all producers who are found non-compliant will face a wide range of penalties ranging from fines to jail time.

Rumor: Water-soluble antibiotics are not affected.

That’s false. A prescription, not a VFD, will be necessary for medically important antibiotics used in drinking water.

What resources are available on the Veterinary Feed Directive?

Staying up-to-date on the latest information is key. Alltech highly recommends going straight to the source to get the most complete information. There are several comprehensive resources available online:

• The FDA website. Here you can find brochures outlining the requirements for producers, veterinarians and feed distributors, whether or not they manufacture feed.
• This FDA video gives an overview of the VFD.
• The Beef Cattle Institute at Kansas State University has created free modules on the VFD.
• In this webinar, Dr. Darrell Johnson from the University of Kentucky speaks in depth about the unique challenges faced by beef and dairy producers affected by the VFD.
• WATT and GlobalVetLink put together this great infographic.
• Your local agriculture extension office.

When it comes to your animals’ mineral diet, you’ve likely never been thinking about “Star Wars” but just like the characters of the epic movie series, you have a choice to make. Do you go with organic trace minerals, or do you turn to the dark side: inorganics?

It should be an easy choice, but many get led astray by practices that date back over a decade-and-a-half. If you were to look at how many times the human food pyramid has been updated since then, you would see constant improvement. Likewise, how can we keep our animals’ diets in pace with this constant development of nutritional innovation? It starts with choosing a side when it comes to your minerals.

Choose the side with less mineral waste

To examine an animal’s diet, you often have to look at what is coming out the other end. If the animal’s waste has undigested feed in it, that signals two possibilities: One, the diet is over-fortified with an ingredient; or two, the animal is having trouble digesting the ingredient. Recent studies have shown that grow-finish pigs fed a diet with the total replacement of inorganics with organic minerals had reduced fecal manganese, copper and selenium excretion (Alltech-Zhejiang University Animal Nutrition and Feed Science Research Alliance). Another study looking at supplementing organic trace minerals at 0, 50 or 100 percent of the National Research Council (NRC) recommendations showed that nursery pigs and finishing pigs’ trace mineral requirements did not appear to need dietary trace mineral supplementation at the levels recommended by NRC. This research highlights the fact that organic minerals are better absorbed, stored and utilized by the animal. The more that is absorbed by the animal means less waste reaches the environment and less is wasted from the producer’s pocket book.

Choose the side you can trust

Not all minerals are made the same. Inorganics have an added level of contamination risk for both feed and food. This comes in the form of dioxins, PCBs and heavy metals. In the 2015 Asia-Pacific Heavy Metal Survey, where 498 mineral samples were tested, the trend for heavy metal contamination over the past five years showed an average of 19.4 percent. This contamination figure should be scary for producers, as that leads to an increased risk of immune suppression, liver/kidney damage, decreased growth and even contamination of the tissue. It is important to know where your minerals are coming from and that they are being tested to ensure safety for your animals and the food chain. Alltech’s Q+ (Quality Plus) process is a positive release program that guarantees all incoming batches of raw material sources and final product batches are tested for dioxins, PCBs and heavy metals prior to sale, providing a safe and traceable product that producers can trust.

Choose the side that’s better for your pigs’ health and performance

Minerals are an important part of the pig’s diet, but they are not meant to be just another ingredient. Effective mineral nutrition can have a very significant on health and performance. Organic trace minerals have shown to support the number of pigs born (The Ohio State University). That means a lot for producers looking to reduce overall production costs per pig. In addition to reducing costs, another major concern is the health of the pig. Additional studies have shown that trace minerals supplementation supports healthy antioxidant status. This allows the pigs that the producer has invested in to be healthier and more likely to make it to market (Alltech-Zhejiang University Animal Nutrition and Feed Science Research Alliance).
