Join us on Tuesday, June 7 as Dr. Mike Van Amburgh will discuss the effects of nutrient intake from weaning to calving, its effect on lifetime productivity and the economic outcomes of this approach. Data suggests growth rates from birth to weaning account for as much as 22% of the variation in first lactation milk yield. In addition, there is a lifetime milk yield response related to nutrient intake over maintenance up to 49 days of life, showing the milk yield response increases with greater nutrient intake. Bottom line: we can increase lifetime performance through better nutrition and management prior to weaning.
Historically, calf feeding programs have focused on survival and reducing the incidence of disease through weaning, followed by moderate growth to puberty for maximized first lactation production. However, new studies suggest this approach to calf and heifer rearing has created missed opportunities to capture the greatest lifetime milk yield.

About our speaker
Dr. Van Amburgh is an associate professor in the Department of Animal Science at Cornell University where he has a dual appointment in teaching and research. He teaches multiple courses and works extensively with the Dairy Fellows Program, advises approximately 50 students and is the advisor for the Cornell Dairy Science Club. The focus of his research program for the last 15 years has been to further the understanding of nutrient requirements of dairy calves and heifers and aspects of endocrine control of developmental functions such as mammary development and puberty. He currently leads the development of the Cornell Net Carbohydrate and Protein System.
