Animal Health

Healthy animals are more productive animals

MFA knows that livestock producers are vital to the food chain. We support that role with medications, vaccines and supplies to help keep animals healthy, safe and profitable.

Building a healthy foundation

Ensuring that animals are free of disease, in good condition and performing at their best benefits everyone involved—from the farmers who raise them to the people who consume their products.

Farm animals are susceptible to a range of health threats, and common livestock diseases can jeopardize your operation’s financial health. It’s almost always easier and safer to prevent livestock diseases than to treat them. MFA has the products and expertise to help. While MFA does not maintain an online catalog of animal health products, our retail locations offer a full line of over-the-counter (OTC) labeled medications and vaccines from all the major manufacturers. Along with that selection, we have staff who are trained to help you make the best decisions about what products to use and how to use them. Our animal health offerings are intended to complement the production advice and assistance provided by your local veterinarian. Please let us know how we can help by contacting any of the MFA Animal Health professionals or your livestock key account manager.

What is a VFD and why do I need one?

Veterinary oversight of prescriptions now required for most livestock antibiotics

To purchase medicated feed products containing antibiotics from MFA, producers must have a valid Veterinary Feed Directive (VFD) on file with your retail location. This regulation was put into effect in 2017 by the Food and Drug Administration to require veterinary oversight or consultation for antimicrobial drugs that are considered necessary for assuring animal health. 

Following this guidance “medically important antimicrobials”—medications that are used in treating human disease—administered through feed and water must have a VFD or prescription status. The VFD is a written statement issued by a licensed veterinarian that authorizes the use of a regulated drug or combination drugs in or on animal feed, even if the animals are not intended for food production.

In an extension to these rules, most other forms of these over-the-counter (OTC) animal antibiotics—injectable, topical, intramammary tubes and oral products—are now prescription-only as of June 2023. These medications can only be used in animals under the supervision of a licensed veterinarian. Producers are still able to purchase a full line of OTC animal health products that do not require prescriptions from their local MFA.

MFA Director of Animal Health Dr. Tony Martin emphasizes that these antibiotic restrictions put even more focus on the importance of genetics, nutrition, management and preventive animal health measures that all livestock producers should be doing. These practices include minimizing stressors, feeding a fully balanced diet, doing a good job with parasite control and vaccinations to minimize disease and using additives like MFA Shield Technology that help support immunity.

Fight flies with effective pest-control plans

Flies are a nuisance. They are irritating to cattle, horses, stock dogs and, of course, humans. More concerning, they are also vectors for diseases. An integrated pest management program (IPM) is important to control fly popula­tions. Effective fly management is especially critical in feeding oper­ations and dairies because of their confined nature.

No one practice is sufficient to control flies. Effective IPM plans use a variety of practices and control methods to keep fly populations in check, and these measures should start well before fly season begins. There are four important branch­es of an IPM program: cultural, physical, biological and chemical. While each branch is important, the cultural and physical branches are the fundamental components of fly control.

As you implement an IPM plan, monitor its effectiveness. Evaluate fly populations throughout your operation with traps and speck cards. Record which steps are successful and where additional improvement is needed. By carefully evaluating your program, you can make appropriate adjustments as needed.

Cultural practices make a world of difference in fly management. These practices include manure management, regular cleaning of spilled milk and feed, removal of vegetative buildup and soiled or de­caying bedding in cattle areas, and landscape maintenance. Removing these breeding sites for flies dramat­ically reduces their population in a cattle operation. Additional cultural elements also help fly control. These prac­tices include removing tall grasses and weeds, where flies can rest in the plants, regularly cleaning and moving calf hutches and pens, and ensuring that pens are well venti­lated.

Physical efforts are perhaps the most obvious method of fly control, though it is not always the easi­est. Structures and facilities can be designed to deny flies access to locations, or at least make the areas less hospitable for them. Patching or sealing cracks in structures, in­stalling mesh screens over windows, and sealing around electrical outlets can close off entry points for flies. Installing fans that provide a down­ward and outward air flow reduces fly activity in buildings. Addition­ally, consider strategically placing non-insecticidal sticky, jug or bag traps to aid these efforts.

Biological control involves harnessing the power of natural predators of flies. Parasitic wasps, predatory mites, predatory beetles and fly pathogens are all used to control flies. These methods interrupt the lifecycle of the fly. For instance, predatory beetles feed on fly larvae found in dung, while parasitic wasps lay their eggs inside fly pupae.

Most producers are familiar with the conventional chemical fly-control methods, including foggers, baits, perimeter sprays and on-animal treatments. When using these products, remember to rotate active ingredients so flies do not become resistant. Chemical control also includes feed-through insect growth regula­tors (IGRs). Feed-through products prevent the emergence of adult flies. These products work by delivering an important active ingredient di­rectly to cattle, where it is eventual­ly passed into the animal’s manure. Flies then lay their eggs on the manure, and the IGR interferes with the lifecycle of the fly. This process prevents biting, breeding adult flies from developing out of the eggs laid in the manure.

A common free-choice MFA cattle mineral used for controlling horn flies on pasture cattle is Ricochet Altosid IGR Shield Mineral. Another IGR is Clarifly, with the active ingredient diflubenzuron, which has a label for four species of flies. It is fed to confined cattle and also approved for swine, horses, goats and sheep. Begin feeding these products about a month before flies begin to appear and continue until about a month after the first frost. This program of 30 days on each side of fly season suppresses fly activity early and reduces overwintering pupae. Feed the product to animals of all ages to treat as much manure as possible.
