Cattle Chat

In this episode of Diving Into Diets on Bovine Science with BCI, Dr. Brad White and Dr. Todd Gunderson discuss a 2026 study on the high prevalence of bovine leukemia virus in cow-calf operations, implications for cow reproduction, culling, and calf weight. The conversation concludes there is not a great association between culling risk and pregnancy status associated with the ELISA test.

On this episode of Cattle Chat, the team discusses how Theileria, a tick-borne parasite that destroys red blood cells, requires laboratory testing for confirmation and cannot be diagnosed reliably from visual signs alone. They emphasized that positive test results must be interpreted alongside clinical signs and herd history, since infection does not always mean it was the direct cause of illness or d...

In this episode of BCI Cattle Chat, the hosts celebrate reaching one million podcast downloads and reflect on memorable guests, listener interactions, and how the show has evolved since it began in 2018–2019. The discussion highlights popular listener question topics over the years, including nutrition, reproduction, management, genetics, markets, and grazing management. The hosts also share insights ...

On this episode of BCI Cattle Chat the experts cover diarrhea caused by coccidiosis, emphasizing that it’s a common organism managed through reducing stress, maintaining clean and dry conditions, and using appropriate feed additives rather than trying to eliminate it entirely. The team also discuss growth implants, emphasizing their use to improve production efficiency and that hormone levels in beef ...

On this episode of BCI Cattle Chat, Larrison Hicks gave a research update on his project about beef–dairy cross calves, focusing on how early-life management, such as milk-feeding methods and probiotics, may influence gut development and the higher incidence of liver abscesses in calf ranch systems. Early findings showed no short-term benefits from probiotic supplementation, with more results pending....

On this episode of BCI Cattle Chat, the experts cover listener questions on calving difficulty, vaccination strategies, and liver fluke management. The team discusses that while malpresentation in calves can sometimes occur in clusters, it is more strongly linked to factors such as calf size, twins, and genetics than to cattle handling, though low-stress handling remains important. They also discuss v...

On this podcast episode of BCI Cattle Chat, the team and guest, Cambree Schmaltz, discuss the CalfDex project, which aims to simplify record-keeping for cow-calf producers and help them use data more effectively for management and economic decisions. They also answer a listener’s question about the risks of transporting pregnant cattle, emphasizing that early pregnancy is the most vulnerable per...

In this episode of BCI Cattle Chat, the team discusses beef imports and brucellosis in the cattle industry. The experts explain that the U.S. imports lean beef to complement domestic production, especially for ground beef, while exporting other cuts, such as liver and tongue, helping balance supply and meet consumer demand. They also review brucellosis, a bacterial disease that affects reproduction an...

In this episode of BCI Cattle Chat, the team mixes listener questions with expert insights on cattle production and education. The team discusses strategies for growing a small herd, emphasizing clear goals, strong local relationships, and patience in a long-term market, while noting that tight supply and strong demand may keep cattle prices elevated in the near future. They also explore animal health...

In this episode of BCI Cattle Chat, Abby Heidari, the director of nutrition for the Kansas Beef Council, discusses the rise of GLP-1 weight-loss medications and their effects on appetite, weight loss, and muscle maintenance. She explains that while these drugs help reduce food intake, maintaining adequate protein and physical activity is essential to prevent muscle loss and support long-term metabolic...

In this week’s episode of BCI Cattle Chat, the team discusses research on reducing heat stress in feedlot cattle and best practices for managing calf scours. Guest Maddie Mancke, a PhD candidate, explains her study comparing morning feeding with nighttime feeding to see whether shifting digestion-related heat production to cooler hours would benefit cattle. The results showed no performance difference...

In this episode of BCI Cattle Chat, the team discusses estrus expression and synchronization strategies used in cattle breeding programs with guest Adrienne Lulay from Select Sires Cooperative. They explore how the intensity of estrus can reflect hormone levels and fertility, helping producers make more informed breeding decisions. The conversation also highlights key factors for reproductive success,...

In this episode of Cattle Chat, the team discusses what it takes to get into veterinary school, including prerequisites, gaining diverse experience, standing out in the application process, and preparing for interviews. They also explore ways to encourage interest in rural and livestock veterinary practice. The team answers a listener’s question for a 125-cow producer, highlighting simple metric...

In this episode of BCI Cattle Chat, the team discusses what producers should consider when purchasing a bull, emphasizing fertility, structural soundness, EPD accuracy, and aligning genetics with herd goals. They highlight the importance of avoiding information overload by focusing on economically relevant traits and practical fit. The group also explores emerging technologies in the beef industry, in...

This episode of BCI Cattle Chat covers liver flukes and emergency preparedness in cattle operations with guest Dr. Christine Navarre. The experts discuss how liver flukes damage the liver, can contribute to sudden death, and may show up in feedlot cattle long after exposure in endemic regions. They emphasize accurate diagnosis, targeted deworming, and vaccination. The team also highlights the importan...

On this week’s BCI Cattle Chat episode, graduate student Liliana Rivas updates us on her research about leaky guts in yearling calves. She conducted this by feeding the calves a restricted diet and measuring indigestible sugars in the bloodstream over 36 hours. The experts also discussed cow efficiency, measured as pounds of calf weaned per pound of feed consumed per cow exposed. A key finding was tha...

The experts discussed whether it is more costly to have thin or fat cows going into the calving season. Thin cows are generally more costly because they are at high risk of having calving issues. Determining when to be aggressive with supplementation is important when addressing thin cows. The team also answered a listener’s question regarding weak calves. They discussed the factors that could b...

On this week’s BCI Cattle Chat episode, the experts debate whether you should start treatment as soon as signs of the disease appear or if you should wait for the signs to develop to have a clear diagnosis. The ability to modify the therapeutic plan can be valuable, but it needs to be balanced with consistency that allows better evaluation of treatment outcomes. The team also debated treatment protoco...

On this week’s BCI Cattle Chat episode, the experts answer a listener’s question comparing two genetically identical bulls raised in different environments. The group discusses whether early development and nutrition can influence fertility, longevity, or even the genetics passed on to offspring, diving into the emerging science of epigenetics. Lastly, the team tackles a listener question on udder qua...
