Did you know?

Antibiotics are medications that fight bacterial infections. They are used in cattle to prevent, control and treat disease. These drugs are very important to ensuring animal health and experts agree their use has contributed to improved food safety over the years.

  • Farmers and ranchers recognize antibiotics must be used carefully in order to preserve their future effectiveness for our families and our animals.
  • Farmers and ranchers avoid using antibiotics that are important to human medicine and have invested in research and education programs designed to help us continuously improve how we use antibiotics.
  • Farmers and ranchers have no reason to overuse antibiotics but rather every reason to use them as selectively as possible. For one, it’s the law, but antibiotics also are a costly input for the small business men and women who raise cattle for beef.

The Veterinary Feed Directive: what does it all mean?

August 31, 2015

In 1996, Congress enacted the Animal Drug Availability Act (ADAA) for the approval and marketing of new animal drugs and medicated feeds. Before that time, drugs used in the animal industry were either over-the-counter or prescription-based. The ADAA created a new category of products called veterinary feed directive drugs (VFD drugs).  These drugs were intended for use in or on animal feed (including water) and were obtained by the producer without a prescription.  The VFD drug category was created to avoid state pharmacy laws for prescription drugs, which were not applicable to medicated feed.  As of October 2015, new VFD regulations will go into effect for animal drugs already labeled as VFD drugs. The new regulations will require the professional supervision of a licensed veterinarian if the VFD drug is deemed medically important. The following provides background information and important points to prepare livestock producers for the upcoming regulation changes.

In 2013, the Food and Drug Administration Center for Veterinary Medicine (CVM) published a guidance document, which called on animal drug companies to voluntarily stop labeling drugs that are medically important as drugs that can be used to promote animal growth. The purpose of this request was to decrease the incidence of antibiotic resistance in both human and animal medicine.  The guidance document also requested that animal drug companies change the labeling of their products to require a written VFD order by a veterinarian.  The CVM felt that putting these drugs under veterinary control would guarantee that they would be used only when necessary for assuring animal health.  All of the animal drug companies contacted committed in writing to participate in the new drug marketing strategy. The VFD final rule was published in the summer of 2015.  Animal drug companies have until January 2016 to relabel their VFD drugs.

The most important provision of the VFD final rule is the requirement of veterinarians to issue all VFD orders within the context of a veterinarian-client-patient relationship (VCPR).  A valid VCPR is the basis of veterinary supervision and provides a legal agreement between the veterinarian and livestock producer.  Only veterinarians actively licensed and in good standing in Arkansas can write VFD orders for production facilities in Arkansas.  In order for a veterinarian to issue a VFD order, he/she must do the following:

  • The veterinarian takes responsibility for the health of the animals and the client agrees to follow the veterinarians’ instructions.
  • The veterinarian knows the animals enough to make a preliminary diagnosis of the medical condition for which they will be treated. This means the veterinarian has either examined the animals or has had timely visits to the operation where the animals are managed (at least one visit per year to be valid in Arkansas).
  • The veterinarian is readily available for follow-up evaluation or has arranged continuing care and treatment with another veterinarian or emergency service.
  • The veterinarian provides oversight of treatment, compliance and outcome.
  • The veterinarian maintains records of treatment (3 years in Arkansas).

Along with a valid VCPR, veterinarians must become familiar with the labeled use of VFD drugs in the feed.  The VFD drug can only be used to treat diseases indicated for a specified duration of time on the label.  To do otherwise is called “extralabel use”, which is not allowable under the VFD final rule.  A VFD order must contain all of the following:

  • Veterinarian’s name, address and telephone number
  • Client’s name, business or home address and telephone number
  • Premises at which the animals specified in the VFD are located
  • Date of VFD issuance with an expiration date
  • Name of the VFD drug(s)
  • Species and production class of animals to be fed the VFD feed
  • Approximate number of animals to be fed the VFD feed
  • Indication for which the VFD is used
  • Level of VFD drug in the feed and duration of use
  • Withdrawal time, special instructions and cautionary statements necessary for use of the drug in conformance with the approval
  • Number of reorders (refills) authorized, if permitted by the drug approval, conditional approval or index listing
  • Addition of the statement “Use of feed containing this veterinary feed directive (VFD) drug in a manner other than as directed on the labeling (extralabel use), is not permitted”
  • An affirmation of intent for combination VFD drugs as described in 21 CFR 558.6(b)(6)
  • Veterinarians electronic or written signature

To find a veterinarian in your area, please contact your county extension agent.  To find out more information on the VFD along with fact sheets and the list of medically important drugs used in animal medicine, go to:

Stockpiled fescue Wright

Stockpiled fescue is one of the most reliable and cost-effective practices for growing winter pasture?  Clip the old summer residue of fescue fields down to a 3” stubble and apply 50-60 lbs/acre of nitrogen fertilizer the first week of September. Let the grass grow until December 1 then graze it instead of feeding hay. Typical yields are 2,000 to 3,000 lbs of forage per acre. Over 98% of University on-farm stockpiled fescue demonstrations have saved producers money over the past 18 years.

Did you know, cows have a single stomach, but four different digestive compartments. The four compartments consist of the following:

  • Rumen is the largest compartment, and it contains billions of bacteria, protozoa, molds, and yeasts.
  • Reticulum, with its honeycomb like lining, is a compartment of the stomach that is involved with rumination. It also acts as a trap for foreign objects ingested by the cow.
  • Omasum is also known as “the book” or many piles because of its many leaf-like folds. It functions as the gateway to the abomasum, filtering large particles back to the reticulorumen and allowing fine particles and fluid to be passed to the abomasum.
  • Abomasum is also known as the “true stomach.” It functions much like the human stomach producing acid and some enzymes to start protein digestion.

2015 Arkansas Hay Test Trends for May through July

2015 Arkansas Hay Test Trends for May through July



The 2015 hay crop in Arkansas has been challenged with an abundance of cool days and rain during late spring and early summer.  Even after rain ceased, harvest was delayed while hay and livestock producers waited for water logged soils to dry out.  Warmer and dryer days gave way to good forage growth during the wait.

Livestock producers and county agents have reported first-cutting being delayed, even into late-July.  For the 3-month period of May, June, and July the total number of hay samples submitted to the University of Arkansas diagnostics lab was 216, slightly below the 5-year (2010-2014) average of 227 samples.  Sample median protein level was 10.6%, which is 4% lower than samples submitted during this period last year and 7% lower than the previous 5-year average.  Fiber analysis (acid detergent and neutral detergent fiber) during the 3-month period was similar to the 5-year average, and the median total digestible nutrients estimate for submitted samples was 56%.

The fiber content (greatly affected by plant maturity at harvest) of samples submitted to the lab thus far aren’t in line with expectations attributed to this summer’s field conditions.  Keep in mind, 216 samples is an extremely small sample of the total hay harvest.

One consistent trend observed in hay samples over the past 10 years in Arkansas has been lower protein content of hay.

A key lesson to the 2015 hay sample summary thus far is any given farm should not base winter supplementation decisions on lab test averages (a.k.a. “my hay is average quality”).  Within the 216 samples summarized here, the distribution of protein concentration among samples started at a low of 4% and went as high as 22%.

Climatologists are predicting a strong El Nino to develop which means a warmer and wetter winter.  While warmer sounds favorable toward easier cow maintenance, a wet hair coat will drastically reduce the lower critical temperature for cattle, creating a greater demand for energy in the diet.

As hay harvest is wrapped up, no pun intended, follow up with your county Extension agent to have hay lots analyzed for nutrient content and plan a winter feeding program that won’t compromise cow reproduction or the pocket book.

Did you know that blue-green algae isn’t an algae at all?  It is actually a bacteria called cyanobacteria that gets its energy by photosynthesis just like algae. Blue-green algae are most often blue-green in color, but can also be blue, green, reddish-purple, or brown.  Blue-green algae reproduce explosively under certain conditions (usually in late summer) and some species produce toxins that can be fatal to humans and animals.  Since there is no way of knowing which blue-green algae are fatal, we suggest that access to ponds are prohibited when algae blooms (also called pond scum) are present.
