    Episode 357 - From Calf to Carcass: Early Nutrition for Beef-on-Dairy Success - UMN Extension's The Moos Room

    Beef-on-dairy calves continue to bring strong prices, but producing calves that perform well from birth through harvest requires careful decisions about genetics and nutrition. In this episode, we look at current Minnesota calf markets, the factors influencing beef sire selection and recent research exploring how early feeding programs affect the long-term performance of Angus-Holstein calves. A University of Minnesota study compared conventional 20:20 milk replacer with a higher-energy 24:24 formulation. Calves receiving the 24:24 milk replacer had greater starter intake, faster weight and frame growth, and improved feed efficiency through eight weeks of age. The results suggest that supplying more nutrients early in life may encourage—not suppress—starter consumption. We also discuss an Iowa State University study that followed beef-on-dairy steers from the nursery through harvest. Although pelleted diets produced faster growth shortly after weaning, cattle raised on forage-based total mixed rations performed better later in the feeding period. The low-starch TMR group finished with heavier body and carcass weights, more Prime carcasses and greater carcass value, while the high-starch TMR group experienced substantially more liver abscesses. The research highlights why early growth should not be the only goal. Rumen health, feed costs, finishing performance and carcass quality all matter when developing profitable beef-on-dairy feeding programs.

    Episode 356 - Heat Stress and Water Intake in Dairy Cows - UMN Extension's The Moos Room

    This episode examines how heat stress affects water intake in dairy cows—and why farms must prepare their watering systems for increasingly hot weather. A review of studies from 1985–2024 found that Holstein cows producing roughly 65–70 pounds of milk averaged about 24 gallons of water per day under thermoneutral conditions. During heat stress, intake increased by approximately 10 liters, or 2–3 gallons, per cow per day. Each one-unit increase in the temperature-humidity index was associated with another 1.5 liters of water intake. Although heat-stressed cows produce less milk, they drink more because the additional water supports evaporative cooling and body-temperature regulation. Data from the University of Minnesota’s dairy herd revealed a more complicated picture. smaXtec sensors showed that cows averaged around 23 gallons per day, but estimated intake declined during summer. Possible reasons include warmer drinking water, pasture water access, competition at waterers, and changes in drinking behavior. Cows generally drank only four or five times per day, consuming roughly 14–20 liters at each visit. Peak drinking also shifted from midafternoon in winter to around 7 p.m. in summer, often after milking. These patterns highlight the importance of examining when cows drink—not just daily totals. Farms should ensure adequate water flow, tank capacity, access, and cool water during peak-use periods. Sensor readings are most valuable when compared with each cow’s normal behavior and interpreted alongside weather, milk production, rumination, health events, and management changes. The central message is that water intake can be a useful indicator of heat stress, but unexpected changes should prompt investigation rather than an automatic conclusion. As extreme heat becomes more common, dairy water systems must be designed for peak demand rather than historical averages.

    Episode 355 - How Breed (Holstein and Crossbred) Influences Heifer Feed Intake and Emissions- UMN Extension's The Moos Room

    Brad shares preliminary results from a University of Minnesota study examining feed intake, methane emissions, and feeding behavior in Holstein and crossbred dairy heifers. Using precision feeders, methane-monitoring equipment, and activity sensors, the research team compared Holsteins with ProCROSS and GrazeCross heifers. The early findings show that methane production generally increased with feed intake. Smaller GrazeCross heifers consumed less feed and produced less methane and carbon dioxide, while ProCROSS heifers had the highest feed intake. However, methane produced per unit of dry matter intake did not differ significantly among the breed groups. Brad also discusses how often heifers visited the feed bunk, how much time they spent eating, and what sensor data revealed about rumination and activity. These preliminary results highlight how body size, breed, and feeding behavior may influence heifer management and environmental efficiency.

    Episode 354 - Hot Calves, Lower Gains: Rethinking Summer Calf Care - UMN Extension's The Moos Room

    Brad takes a closer look at heat stress in dairy calves and cows. This episode highlights several recent studies on how temperature-humidity index affects calf behavior, lying time, respiration rates, shade use, and growth performance. Brad discusses research from the University of Guelph, The Ohio State University, and Mississippi State showing that heat-stressed calves spend less time lying down, stand more often, breathe harder, and may gain less weight when shade is not provided. He also reviews a Texas A&M study using precision livestock technology to monitor drinking behavior, rumen temperature, and heat stress responses in robotic milking herds. The big takeaway: heat stress in calves deserves more attention. Simple strategies like shade cloth, better ventilation, and more thoughtful housing design may help improve calf comfort, growth, and long-term performance.

    Episode 353 - Calf Research Roundup: Colostrum, Beef-on-Dairy, and Weaning Insights - UMN Extension's The Moos Room

    Back from the ADSA annual meeting in Milwaukee, Brad shares highlights from several calf-focused dairy studies. This episode covers new research on colostrum management for beef-on-dairy crossbred calves, including how feeding practices differ between retained dairy heifers, beef-on-dairy calves, and calves not kept on farm. Brad also reviews a study comparing fixed-age weaning with starter-intake-based weaning in Holstein and Angus-Holstein calves, plus new work using ear tag sensors to track calf behavior, rumination, eating, and activity through 150 days of age. The episode wraps up with research from the University of Florida on colostrum yield, quality, and genetics, including how season, parity, calf sex, gestation length, and days dry can influence colostrum outcomes.

    Episode 352 - Somatic Cell Count Genetics and Heifer Feed Efficiency - UMN Extension's The Moos Rom

    Brad shares two studies He presented at the American Dairy Science Association annual meeting. First, he examines records from more than 150,000 lactations to compare genetic predictions for somatic cell score and clinical mastitis. The results suggest that PTA for somatic cell score is more useful for predicting and ranking cows by observed somatic cell count than PTA for mastitis. He also discusses a study comparing Holstein and crossbred heifers for feed intake, methane emissions, rumination, and feeding behavior. Although methane produced per kilogram of feed was similar across breed groups, smaller crossbred heifers consumed four to five pounds less dry matter per day. The findings highlight how genetics, breed, sensors, and precision feeding data could help producers improve herd health and heifer management.

    Episode 351 - High Oleic Soybeans: A New Tool for Dairy Rations? - UMN Extension's The Moos Room

    Brad discusses what he learned about high oleic soybeans at the Four State Dairy Management and Nutrition Conference in La Crosse, Wisconsin. High oleic soybeans are gaining attention in dairy nutrition because they can provide both rumen undegradable protein and a more rumen-friendly fat source, potentially reducing the need for purchased protein and fat supplements. The episode covers how high oleic beans differ from conventional soybeans, why roasting quality matters, and how measures like protein dispersibility index help determine whether beans are under- or over-processed. Brad also reviews feeding rates, farm case studies showing milk fat and energy-corrected milk responses, possible cost savings, and the pros and cons of adopting high oleic beans on dairy farms. Overall, high oleic soybeans are not a silver bullet, but they may offer dairy producers another tool for improving ration economics, milk components, and on-farm feed production when managed carefully.

    Episode 350 - New World Screwworm Returns to the U.S.: What Farmers Need to Know - UMN Extension's The Moos Room

    A case of New World screwworm was recently identified in a three-month-old calf in Zavala County, Texas, near the Texas-Mexico border. In this episode, Brad breaks down what New World screwworm is, why it matters to livestock producers, and what signs to watch for in cattle and other animals. He explains how the larvae infest live tissue, how the pest spreads, and why early detection, reporting, quarantine, and treatment are key to preventing further spread. The episode also clears up common myths, including whether screwworm spreads animal-to-animal or person-to-person, whether whole herds must be culled, and whether recovered animals can enter the food supply. Brad also discusses past eradication efforts using sterile flies, current treatment options, and the importance of producer awareness, especially for those in areas at higher risk.  Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!
