(Elsevier) The United States Department of Agriculture-National Animal Health Monitoring System (USDA-NAHMS) conducted a survey of 2,545 preweaned heifer calves across 104 dairy operations in 2014. The study, which took place in 13 states over 18 months, covered a large cross-section of management of preweaned heifer calves in the United States, and the results have been published in six new articles in the October issue of the Journal of Dairy Science.
