How Heritable Is Fertility in Beef Cattle? (opens the original)
Read excerpt
In this episode of Bovine Science, we examine a 2024 Journal of Animal Science study that used hundreds of thousands of cattle records to investigate the genetic and environmental influences on fertility in beef cattle. The study evaluated traits including calving date, calving interval, first-calf interval, early calving, and heifer pregnancy. The discussion highlights that most fertility traits have very low heritability, meaning management decisions such as nutrition, body condition, breeding
A New Approach to Mycoplasma Control: Evaluating a Modified-Live Vaccine in Young Calves (opens the original)
Read excerpt
This episode reviews a 2026 study investigating whether a modified-live Mycoplasma bovis vaccine can help protect young calves from one of the most frustrating respiratory disease pathogens in the cattle industry. The researchers conducted a controlled challenge trial in neonatal calves, comparing vaccinated and non-vaccinated groups after exposure to Mycoplasma bovis . The results showed several encouraging outcomes for vaccinated calves. They experienced fewer lung lesions, fewer days with fev
Solving the Toxicology Mystery: A Systematic Approach to Vague Cattle Health Problems (opens the original)
Read excerpt
This episode focuses on some of the most challenging cases veterinarians encounter: cattle with vague signs such as weight loss, poor condition, or an unexplained death where no obvious cause is apparent. Dr. Scott Fritz explains that these situations are often far more difficult than classic acute poisonings because there is rarely a clear syndrome, exposure event, or obvious diagnostic clue. Instead, investigations must begin with a thorough history, careful necropsy, and a detailed evaluation
Do Vaccines Affect Bull Fertility? Evaluating Breeding Soundness After Modified Live and Killed Vaccines (opens the original)
Read excerpt
This episode examines a 2025 study that investigated whether modified-live or killed viral vaccines influence bull breeding soundness exam (BSE) results. The research addressed a common practical question among producers and veterinarians who are concerned that vaccination before breeding season might negatively affect fertility. Researchers randomly assigned mature bulls to receive either a modified-live or killed vaccine and then evaluated semen quality and breeding soundness multiple times ov
Rethinking Vitamin A in Beef Cattle: Why Calves May Be Deficient Despite Green Grass (opens the original)
Read excerpt
This episode explores the role of vitamin A in beef cow-calf systems and examines why some calves develop low vitamin A levels and respiratory disease even while grazing alongside cows on green pasture. The discussion highlights that vitamin A nutrition is more complex than simply having access to lush forage, because cattle primarily consume beta-carotene from grass, which must be converted into usable vitamin A by the body. A major takeaway is the importance of colostrum as the primary source
