Coccidiosis induced Diarrhea, Growth Implants in Beef, Timing When Processing Calves

Posted on by

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 are biologically minimal, though consumer preferences may justify selling non-implanted beef at a premium. The last topic was a listener question that asked about protocol when gathering cattle before processing. The veterinarians discussed that timing should minimizing stress while ensuring access to feed and water.

Research Update: Larrison Hicks, Line Breeding, Nutritional Listener Questions   

Posted on by

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. The hosts also discussed genetics, noting that line breeding closely related high-performing cattle increases the risk of defects and does not reliably produce superior offspring. Additional topics included managing aflatoxins in feed, the limited effectiveness of sodium bicarbonate in feedlot diets, and how excess fat can negatively impact rumen function in grazing cattle.

Diving into Diets: Fertilization vs. Supplementation in Grazing Cattle

Posted on by

In this episode of Diving into Diets on Bovine Science, Dr.Brad White and Dr. Phillip Lancaster discuss a 17-year study comparing fertilizing pasture versus supplementing cattle on smooth bromegrass and found that supplementation led to higher daily gains and greater gain per acre than either fertilized or unfertilized systems. Fertilization increased carrying capacity but did not improve individual animal performance compared to the control. Importantly, supplementing cattle maintained soil nitrogen levels similar to those in fertilized pastures, likely due to manure recycling, with no long-term effects on forage stands. Overall, the results suggest producers can flexibly choose between fertilization and supplementation based on economics, with supplementation also reducing year-to-year variability in performance.

GLP-1 Use and Beef Dietary Guidelines

Posted on by

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 health. The conversation highlights beef as a nutrient-dense, high-quality protein source that can support muscle preservation and overall nutrition during weight loss. The group also touches on updated dietary guidelines, emphasizing that beef can be part of a healthy diet when consumed in appropriate portions and in conjunction with balanced eating habits.

Research Update: Maddie Mancke and Scours Management 

Posted on by

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 differences, indicating night feeding could be a practical option without harming cattle. The experts also answer a listener’s question about calf scours, emphasizing that treatment should begin quickly when calves show signs of dehydration or depression. They stress that prevention through clean calving environments and separating newborn calves from older calves is the most effective way to reduce scours outbreaks.

Diving into Diets: Organic vs. Inorganic Minerals in Beef Cattle

Posted on by

In this episode of Diving Into Diets on Bovine Science with BCI, the experts discuss a 2025 meta-analysis comparing organic and inorganic trace mineral supplementation in beef cattle during preconditioning and feedlot receiving. They explain the biological differences between mineral sources and review results from about 20 studies included in the analysis. Overall, organic minerals showed a small improvement in average daily gain, but no effect on cattle morbidity. The discussion highlights that while organic minerals may provide slight performance benefits in certain situations, the overall effects are relatively small and context-dependent.

Diving into Diets: Phosphorus and Calcium in Lactating Beef Cows

Posted on by

In this episode of Diving into Diets, the discussion examines how different phosphorus and calcium diets affect phosphorus retention, milk composition, calf growth, and bone status in beef cattle. While cows on lower-phosphorus diets maintained milk production and calf growth in the short term, they mobilized phosphorus from bone, unlike cows on high-phosphorus, high-calcium diets. The takeaway is that cows are resilient and can tolerate short-term deficiencies, but inadequate long-term mineral intake may eventually impair performance, underscoring the need for appropriate supplementation.

Research Update: Liliana Rivas and Cow Efficiency

Posted on by

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 that the nutrition models in the study underestimated the extent to which energy restriction harms reproduction.

Diving into Diets: Volatile Fatty Acids

Posted on by

On Dividing into Diets, Dr. Brad White and Dr. Philip Lancaster explore how a ruminant’s diet influences the production of volatile fatty acids (VFAs), such as acetate, propionate, and butyrate, created through the fermentation of carbohydrates and proteins in the rumen. They explain that different types of feed support different bacterial populations, shifting the balance of VFAs. For example, grain-heavy diets boost propionate levels, while high-forage diets favor acetate. Despite these shifts, overall animal efficiency depends more on the total amount of volatile fatty acids produced than on the specific proportions. The experts note that attempts to manipulate VFA ratios can be expensive and often yield only minor improvements in productivity.

Diving into Diets: Grazing Behavior

Posted on by

On this week’s episode of Diving into Diets Dr. Brad White and Dr. Philip Lancaster discuss a 2025 study on grazing behavior in cattle, focusing on factors like age, size, hide color, and forage quality. The study tracked 40 cows using GPS collars over three years, finding that older cows traveled further distances, possibly due to learning topography. Red cows traveled more in cold temperatures due to better heat retention from black hides. The study also noted that cows traveled further to high-quality forage areas, as measured by NDVI and IRG, and up slopes and to water sources. The study’s individual hypothesis testing approach limited the interpretation of confounding variables like production stage and weather.

Posted on by

In this episode of BCI Cattle Chat, guest Dr. Cassandra Olds continues the discussion of Theileria, a tick- and fly-borne parasite affecting U.S. cattle herds. The team explains how it spreads from the East Coast westward, causes anemia-like symptoms, and persists for life in infected animals. They stress prevention through stress reduction, parasite control, and good nutrition, noting that no approved treatment exists. The conversation shifts to preparing heifers for breeding season, emphasizing pre-breeding exams, tracking weight and reproductive readiness, and managing nutrition to ensure early conception and lifelong productivity.
