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.

Virtual fencing is drawing plenty of questions from grazing dairy and beef producers. In this episode of The Moos Room, Brad shares what the University of Minnesota’s West Central Research and Outreach Center learned from using NoFence collars with heifers during the summer grazing season.

Undergraduate interns observed 27 heifers from June through August and compared their behavior with collar records of audio warnings and pulses. The heifers spent most of their observed time grazing or standing, although grazing increased as the summer progressed. Observations associated with pulses showed less grazing and more walking, while warnings and pulses varied widely among individual heifers. Brad discusses what those patterns might mean, including how heifers respond when a virtual boundary moves.

He also looks ahead to testing additional collars and virtual fencing systems with dairy cattle. Future work will examine animal behavior alongside the labor and economics of managing pasture with virtual fences.
