Veterinary Research
Even on dairy farms with relatively low antimicrobial use, tetracycline resistance genes remain common. Historical exposure, environmental reservoirs and differences among cattle groups may all contribute to a more complicated picture of antimicrobial resistance.
Researchers developed an endpoint multiplex PCR assay to detect major viral agents associated with bovine respiratory disease, potentially offering a more accessible option for veterinary diagnostic laboratories.
As cases expand in Washington, researchers are studying whether vaccines can protect cattle, preserve milk production and limit mammary damage.
Five years of diagnostic surveillance reveal age-related and seasonal patterns in bovine coronavirus detection, alongside continued genetic variation.
From analyzing cattle muzzles to recognizing eye changes, artificial intelligence is showing promise as a tool for detecting and monitoring infectious bovine keratoconjunctivitis.
Genital PCR may detect Leptospira more frequently than serology or urine testing in asymptomatic bulls, highlighting the importance of sample selection when investigating bovine genital leptospirosis.
Even when calving requires no assistance, cows can vary widely in labor duration. New research suggests that longer labor may be associated with a stronger inflammatory response after calving.
Researchers found differences in bacterial combinations between mild and severe liver abscesses, adding to investigations into disease progression and potential prevention strategies.
Dose, timing and delivery all shape what transition cows get from supplemental choline.
Inflammation is a normal part of the transition to lactation. The intensity of that response just two days after calving may help identify cows on a less favorable postpartum trajectory.
A Cornell field study examined wound healing, pain sensitivity and growth following two approaches to cautery disbudding.
A redesigned adjuvant may be able to help an injectable BVDV vaccine stimulate both systemic and intestinal immune responses.
For Dr. Brad White, investigating bovine heart disease means looking beyond the heart to understand what is happening throughout the animal.
Considering yeast supplementation for your cattle? Dr. Matt Dodd explains why the specific health goal and product research should guide the decision.
While the search for answers in pregnancy loss usually starts with the mother, a groundbreaking study at Texas A&M’s new biotechnology center turns the spotlight onto paternal epigenetics.
Research from Dr. Sandra Godden highlights how processing, moisture, monitoring and stall management can help reduce the udder-health risks associated with recycled manure solids.
Breed-specific thresholds offer a potential tool for herd-level monitoring of omphalitis, but researchers caution that a normal-sized navel does not rule out disease.
Cattle can carry and shed Leptospira without showing signs of disease, raising questions about how much leptospirosis is going undetected.
Research into cow behavior during labor suggests privacy, space and familiarity may influence how cows progress through calving.
Feed analysis remains an important tool for identifying potential mycotoxin exposure, but researchers are exploring whether biomarkers in blood and urine can provide a different view: evidence of what the animal actually absorbed and how it processed the toxin.
The approach could offer a new way to identify MAP infection by detecting changes in the cow’s blood rather than the pathogen itself.
New whole-farm modeling technology could eventually allow veterinarians to test herd management decisions on a virtual version of the farm before implementing them in the real world.
New pathology research suggests we may need to look beyond obvious cardiac lesions as researchers work to unravel one of the beef industry’s most challenging diseases.
Routine milk spectra could help identify dairy cows with greater heat resilience while revealing the biology behind how cattle cope with heat stress.
USDA-funded projects are tackling some of the biggest challenges in New World screwworm control, from producing more competitive sterile flies to developing entirely new ways to eliminate the parasite.
A new study has found Bovine Leukemia Virus DNA in biting insects, adding evidence for a possible role in the virus’ transmission.
New Missouri-based research offers insight into how bovine anaplasmosis spreads naturally and why infected ticks have remained so difficult to detect.
