Breeding Soundness Exam: A risk management tool for cow calf producers

Profitability for the cow calf producers starts with high pregnancy rates and a high percentage of the calves being conceived early in the breeding season. A critical component of reproductive success is having sound, highly fertile bulls. This requires bull(s) that can detect cows in estrus, successfully mount and deliver viable, normal sperm into the reproductive tract of the cow. A proven method to determine the breeding potential of bulls is the Breeding Soundness Evaluation (BSE) system developed by the Society for Theriogenology. The Breeding Soundness Evaluation (BSE) is a relatively quick and economic procedure that can be performed by your veterinarian. It is recommended that all bulls be checked annually, within 60 days of the start of the breeding season. The BSE system is a screening procedure that places bulls into categories of satisfactory, unsatisfactory or deferred. The BSE system is most effective in identifying bulls at the lower end of the fertility spectrum. Eliminating bulls from the breeding herd that the BSE system has determined to be less fertile (classified as unsatisfactory potential breeders) and replacing them with bulls that are classified as satisfactory potential breeders increases the likelihood of high pregnancy rates and high percentage of calves being conceived early in the breeding season.


FDA seeks public comment on risk assessment of drug residues in milk

In the agency’s efforts to support openness and transparency, the FDA is seeking public comment on a risk assessment of drug residues in milk and milk products. The risk assessment was conducted as part of the overall effort to continuously work with industry and state partners to improve an already strong and effective regulatory system for milk and milk products.


Genetic markers for fetal overgrowth syndrome discovered

Humans and cattle share a similar epigenetic fetal overgrowth disorder that occurs more commonly following assisted reproduction procedures. In humans, this disorder is called Beckwith-Wiedemann syndrome (BWS), and in cattle it is called large offspring syndrome (LOS) and can result in the overgrowth of fetuses and enlarged babies.


USDA awards research grants to increase food security, livestock health

The U.S. Department of Agriculture's National Institute of Food and Agriculture (NIFA) today announced three grants designed to boost food security by minimizing livestock losses to insects and diseases. The awards to support research, education, and Extension efforts were made through NIFA's Agriculture and Food Research Initiative (AFRI), which is authorized by the 2014 Farm Bill.


Large-volume intravenous (IV) solution shortage

Due to the shortage of 3- to 5-liter volume units of fluids intended for intravenous (IV) administration in large animals, the FDA’s Center for Veterinary Medicine (CVM) is temporarily exercising enforcement discretion for the distribution of IV fluid products into the United States.


Feedlot inventories up slightly

So far this year, the number of cattle and calves on feed in the United States has run very close to that of a year ago, and the April Cattle on Feed report from USDA shows the trend continuing. As of April 1, cattle in feedlots with capacity for 1,000 head or more totaled 10.8 million head, up by less than 1 percent from a year earlier.
