Are the basics of calf management getting overlooked? Fresh from dairy research meetings in Florida, Brad explores a North American survey led by Penn State’s Melissa Cantor examining the management challenges calf health professionals encounter on dairy farms.

Brad discusses how low milk allowances, larger calf groups, inconsistent routines, and poor ventilation can contribute to challenges with respiratory disease, scours, and navel infections. He also shares examples from the University of Minnesota’s dairy herd and explains why troubleshooting calf health requires looking beyond treatments to everyday feeding, housing, and care.

Topics include:

• Milk allowances and the importance of adequate nutrition.
• Group size, feeding competition, and disease exposure.
• Written protocols for colostrum feeding, sanitation, and navel care.
• Clean, dry maternity pens and hygiene at birth.
• Winter ventilation and timely delivery of adequate colostrum.

The take-home message: healthier calves start with consistent management. Before investing in new equipment or changing treatment strategies, review the fundamentals—and make sure everyone caring for calves understands and follows the farm’s protocols.

Does a second colostrum feeding give newborn calves an extra boost? In this episode of The Moos Room, Brad explores University of Minnesota research involving 150 dairy and beef-on-dairy calves that examined how a second colostrum meal—and feeding by bottle versus tube—affected immunity, health, appetite, and behavior.

On a farm delivering high-quality colostrum within one hour of birth, a second colostrum feeding eight hours later did not significantly increase blood IgG concentrations compared with feeding milk replacer. Brad discusses why that strong first feeding matters when interpreting the results and what the study revealed about second-meal intake, subsequent appetite, and feeding labor. Bottle-fed calves often left part of their meal unfinished, while researchers observed no colic events during the study’s first 72 hours under the feeding protocols evaluated.

The practical takeaway: prioritize the timing, quality, and quantity of the first colostrum feeding. Tune in for a discussion of how second feedings fit into calf management, why meal size and spacing matter, and why these findings do not rule out other benefits of continued colostrum or transition milk feeding.

Fresh from World Dairy Expo, Brad Heins discusses the newly identified HYAL1 mutation in Holstein cattle and its implications for cow health, longevity, and farm profitability. Research in Switzerland and France links this recessive variant to swollen hocks, joint fluid buildup, impaired mobility, and reduced productive life in cattle that inherit two copies.

Brad explains how researchers uncovered a genetic problem that standard additive analyses missed, why joint abnormalities can appear before first calving, and how affected animals may experience lower production and earlier culling. He also explores the importance of combining genomic data with observations of cattle and how genetic testing and avoiding carrier-to-carrier matings could help prevent affected calves. Tune in for a practical look at what this discovery could mean for dairy breeding decisions and healthier, longer-lived cows.

The reported 4.4% and 8.4% are allele frequencies, not percentages of affected cattle; and affected animals inherit two copies of the variant.
