Serum protein profiles under study

Researchers at the University of Minnesota’s Waseca-based calf-and-heifer-rearing facility run a serum protein test on all incoming calves. Last year, the research center brought in 787 calves from three commercial Minnesota dairies. Average serum protein concentration of those calves was 5.5 grams per deciliter, which meets the facility’s goal. What’s more, 45 percent of those calves had profiles greater than 5.5. To see a chart that shows how serum protein levels of incoming calves have changed at the facility, go to: www.dairyherd.com.
