A three-year commitment to serve in areas lacking sufficient veterinary resources has qualified veterinarians for a loan repayment assistance program. The incentives are for students to take up rural veterinary practices and help take care of American livestock. A map of veterinary service shortage areas by state is available online.

AAEV hosting BVDV webinars
Research about BVDV and management practices continues. Although we have good working knowledge of BVDV, losses remain substantial across the production channels. Julia Ridpath, PhD, studies BVDV and related pestiviruses at the USDA’s National Animal Disease Center (NADC) in Ames, Iowa. Webinars presented by her are available through the American Association of Extension … [Read more...]
Knowledge gap looms on FDA antibiotic rules
With big changes to rules governing antibiotic use in animal agriculture pending at the end of this year, producer opinions range from cautious support to skeptical opposition. Some are taking a wait-and-see approach. John Maday, Bovine Veterinarian editor, shared producer survey feedback that indicates the education process is far from finished.

Unique cattle influenza virus studied, named
The executive committee of the International Committee of Taxonomy of Viruses officially announced a new genus, Orthomyxovirdae, with a single species, influenza D virus, because of its distinctness from other influenza types—A, B and C. This is the first influenza virus identified in cattle, explained Professor Feng Li, South Dakota State University. Source: Bovine … [Read more...]
Trichomoniasis is still big trouble
Trichomoniasis could be the most economically damaging disease cow-calf producers face. The trich pathogen, Trichomonas foetus, is a single-cell protozoa, transmitted through sexual contact. Bulls are the primary sources for spreading the disease. Thus, testing bulls is the most effective means of controlling or eliminating trich from cow-calf herds. Source: Bovine … [Read more...]
Progress on foothill abortion disease
After more than 50 years of research, scientists have built a better understanding of the unusual biology of the disease pathogen and vectors for epizootic bovine abortion (EBA). The pathogen, transmitted by the Pajaroello tick, typically does not cause disease in cows or heifers, but does affect the developing fetus in pregnant females, resulting in abortions or … [Read more...]
Understanding risk from zoonotic disease
The majority of infectious diseases emerging as human epidemics originated in mammals. Yet, we still know little about the global patterns of mammal-to-human pathogen transmission. Researchers at the Cary Institute of Ecosystem Studies and the University of Georgia have assembled world maps of what’s on record about mammal-to-human diseases. The work is helping to determine if … [Read more...]
Another E. coli
E. coli O165:H25, is an enterohemorrhagic strain that can cause disease in cattle and could poses a food safety hazard for humans. It is a potential risk in young calves and recently caused enteric disease in feedlot heifers. Source: Bovine Veterinarian, April 25, 2016. The 0165:H25 serotype is similar to E. coli O157:H7, and could be an emerging food-borne pathogen in … [Read more...]
Dewell simplifies cattle euthanasia
For bovine practitioners, humane euthanasia is important in proper animal care and veterinary medicine. In the field, euthanasia of cattle often involves using a firearm or a captive-bolt device. Renee Dewell, DVM, MS, presented a simple way to determine the optimal point of entry for euthanizing cattle with either. She cleared up confusion on the issue. Source: Bovine … [Read more...]
Airborne transmission suspected in human M. bovis cases
The human-animal bond takes on a different meaning when zoonotic diseases are involved. Cases like these underscore the importance of best management practices in production protocols, food safety and disease prevention. Source: Bovine Veterinarian, March 09, 2016. Investigations into two human cases of Mycobacterium bovis infection resulting in tuberculosis (TB) in … [Read more...]
