Smaller dairy cows prove more efficient in milk production
University of Minnesota researchers from the Northwest Experiment Station show smaller Holstein cows are, on average, 4.5 percent more efficient than larger cows in converting feed to milk. Data from 68 cows across 16 years indicate small cows consume less feed by body weight, with medium grain levels yielding the best net energy efficiency and notable variation among individuals.
