Dr. Jud Heinrichs

Professor, Penn State University

Dr. Jud Heinrichs began his career with Penn State University in 1982, initially in an extension appointment and later in an extension/research appointment where his focus lies with dairy nutrition and management with an emphasis on replacements. His interest in the growth and management of dairy heifers has allowed him to work on several population studies of growth rates of dairy heifers as well as revise the Holstein weight tapes currently used worldwide. He is also a co-inventor of the Penn State Forage and TMR Particle Size Separator. During sabbaticals, he has studied the physically effective fiber needs of lactating cows in Italy and was in charge of the National Dairy Heifer Evaluation Project. He has authored more than 135 journal articles and book chapters as well as extension publications.
