For several years, the Food and Drug Administration (FDA) has been taking steps to help regulate and track the use of antibiotics and antimicrobials in feedstuffs with the Veterinary Feed Directive (VFD). 

This directive was started in 2015 to ensure farmers were using medications for their intended purpose and to help curb antibiotic-resistant drugs, focusing on medications often added to rations. Overuse of antimicrobials has led to antibiotic resistance in livestock and people. 

With the final phase of the VFD, all farmers must obtain a written “prescription” from their veterinarian to use the medications. There must be an established veterinarian-client-patient relationship, meaning that the veterinarian must be familiar with the farmer and animals before a written order is submitted. These orders are then given to feed mills and nutritionists to add medication as prescribed. 

VFD Alternatives

With this directive taking effect in June 2023, it might be time to assess your animal health management program. There may be an opportunity for microbials to help play a role in your herd health. By providing animals with yeast, digestive enzymes, vitamins, trace minerals, rumen and intestinal bacteria, we can help support their immune system from the inside out. This allows them to be better nutritionally supported when encountering disease or infection, in turn hopefully having less health issues. 

Research has shown that microbials can be administered continuously to help support animal gut health and the overall health of livestock. Additionally, the data shows that microbials can be directly fed to calves, dairy cows, beef cows, pigs, chickens, and turkeys as part of a herd health management program. 

Helping Animals, Help Themselves

With direct-fed microbials, we may improve animals’ natural microbiomes and gut health. Now is the time to research and consider updated protocols. As you research, consider how microbials can play a role in your herd health without all the additional steps and paperwork that is required by a VFD.
