Veterinary Feed Directive Requirements for Feed Distributors
on 3/4/2017 7:21 PM
Category:Animal Sciences Series

Veterinary Feed Directives are not new to the U.S. livestock industry, but they are new to many Alabama livestock producers, veterinarians, feed mills, and feed distributors following implementation of the updated U.S. Food and Drug Administration (FDA) Veterinary Feed Directive (VFD) guidance in January 2017. Prior to the implementation of these new guidelines, the majority of antibiotics used in or on feed for Alabama livestock were available over-the-counter; meaning livestock producers did not need a VFD from a veterinarian to obtain these medications from feed mills and distributors. This Timely Information Bulletin addresses some frequently asked questions for businesses desiring to manufacture and/or distribute animal feeds containing VFD drugs. Also included with this bulletin are examples of two important documents associated with the manufacture and/or distribution of VFD feeds:

  1. Acknowledgement of Distribution Limitations for VFD Feeds
  2. Notice to FDA of distribution of VFD feeds

These two documents are explained in more detail in the Timely Information Bulletin.

Guide to using medicated feeds containing chlortetracycline for beef cattle in compliance with FDA Veterinary Feed Directive regulations
on 2/18/2017 11:38 AM
Category:Animal Sciences Series

​Chlortetracycline (CTC) is the most commonly used antibiotic in Alabama beef cattle feed and/or drinking water for the control or aid in the control of anaplasmosis caused by Anaplasma marginale; for the reduction of liver condemnation due to liver abscesses; for the control and treatment of bacterial enteritis (scours) caused by Escherichia coli; and for the treatment of bacterial pneumonia (shipping fever) associated with Pasteurella multocida. When used in or top-dressed onto beef cattle feed or mineral mixes, CTC requires a veterinary feed directive (VFD). When used in drinking water, CTC requires a prescription. The attached Timely Information Bulletin explains the process for using medicated feeds containing CTC for beef cattle in compliance with FDA VFD regulations.

Category:Entomology Series

Hot and dry summers make it likely we will have problems with fall armyworms in Alabama forages. It is important to check your forage grasses for fall armyworms, then choose the appropriate control strategy. This timely information sheet discusses how to look for fall armyworm. It also describes control strategies for managing fall armyworms in pastures, hayfields, and forage grasses.

Livestock producers guide to using medicated feeds in compliance with FDA Veterinary Feed Directive regulations

Category:Animal Sciences Series

​Veterinary Feed Directives are not new to the U.S. livestock industry, but they are new to many Alabama livestock producers and veterinarians following implementation of the updated U.S. Food and Drug Administration (FDA) Veterinary Feed Directive (VFD) guidance in January 2017. Prior to the implementation of these new guidelines, the majority of antibiotics used in or on feed for Alabama livestock were available over the counter; meaning livestock producers did not need a VFD from a veterinarian to use these medications. However, things have changed following implementation of the updated FDA VFD guidance, and now all antibiotics administered in or on animal feed require a VFD. The accompanying Timely Information Bulletin addresses some frequently asked questions regarding VFDs to serve as a guide for livestock producers when using feeds containing antibiotics in compliance with FDA VFD regulations.

Changes in Label for Prowl H2O on Forages
on 2/1/2017 2:48 PM
Category:Weed Science Series; Agronomy Series; Animal Sciences Series

In the past, Prowl H2O was only labeled on dormant bermudagrass only. It now can be used on cool-season forage grasses with or without alfalfa (not clovers). It is labeled for grasses grown for forage, green chop, silage, hay production, and/or grown in pastures for livestock grazing. It is also labeled in warm-season grasses however both warm and cool-season grasses must be established (6 or more tillers). The rate is 1.1 – 4.2 quarts per acre however, a split application of 2.1 quarts and 2.1 quarts later how shown to be very effective. It may be tank-mixed with other forage herbicides. Refer to the label for tank-mix partners. Prowl H2O may be applied in the fall, spring, or in-season between cuttings.

Prowl H2O is a dinitroaniline herbicide that controls grasses and small-seeded broadleaf weeds. It will not control emerged weeds. It’s strengths at less than 4 pints include crabgrass, foxtail, panicum, pigweed, smartweed, henbit among others. At 4 pints or greater per acre, it will control annual bluegrass, ryegrass, brome, Japanese stiltgrass (mycrostegium), chickweed, mustards, and knotweed.

There are no grazing restrictions with Prowl H2O. Plant back restrictions to grasses are 10 months so overseeding immediately is not an option.

Prowl H2O may be applied by ground or chemigation, by air, or on dry fertilizer. The minimum application interval is 30 days. The maximum cumulative total allowed per year is 4.2 quarts per acre. Solid stand minimum pre-graze or pre-harvest interval is 0 days. In a mixed stand, a 14-day pre-graze or pre-harvest interval exists.

Prowl H2O rates graphIn a study conducted at Penn State University and the University of Delaware comparing Prowl H2O applied at 1, 2.1, or 4.2 qt/A PRE to weeds and 2.1 qt/A PRE to weeds and after first cutting (May 31).

From the graph beside this, the length of residual crabgrass control increases with the Prowl H20 rate. The 4.2 quart per A rate provided about 12 weeks control but not full-season. However, the split-application of 2.1 quart followed by 2.1 quart did provide season-long control and was the only treatment to do so.

In another study conducted at Virginia Polytechnic Institute, evaluating the same rates but in controlling giant foxtail, they concluded that Prowl H2O at 2.1 quart per acre maximized PRE giant foxtail control. Giant foxtail is an annual foxtail similar to yellow and green foxtail which are prevalent in Alabama. We have a perennial foxtail called knotroot foxtail that we are looking at Prowl H2O and other herbicides to determine the best option for control.

Update on Screwworm Outbreak in Florida
on 1/30/2017 11:59 AM
Category:Animal Sciences Series

In October 2016, screwworm infestations were discovered in Key deer from the National Key Deer Refuge on Big Pine Key, Florida. Prior to this, the New World screwworm, or Cochliomyia hominivorax, has not been a problem in U.S. livestock since the species was eradicated from the U.S. in the 1960s, and programs to prevent their return have worked well. However, with eradication efforts underway on the islands off the South Florida coast, the USDA's Animal and Plant Health Inspection Service (APHIS) recently confirmed the presence of the New World screwworm in a stray dog near Homestead, in Miami-Dade County, on the mainland of Florida. According to the USDA, 13 Florida Keys have had known infestations since October, mostly in Key deer, with five confirmed infestations in domestic animals. State and federal animal-health and wildlife officials have engaged in aggressive efforts to eradicate screwworms from the Keys, including the release of sterile flies. Monitoring efforts have shown reductions in adult fly populations and fewer cases of infested deer. The accompanying Timely Information Bulletin provides additional information about screwworms that animal owners should be aware of to assist with preventing the further spread of screwworms.
