Milk EPD and Calf Performance in Beef Cattle
AgriLife Extension
In a long-term study, Oklahoma State Univ. researchers bred crossbred cows to Angus or Hereford bulls that were either very high or very low for milk expected progeny differences (EPDs). The difference in High and Low Milk EPDs for Angus sires was 27.3 lb. Heifers from these matings were born over a 5-year period (1989 through 1993). When the heifers were 6, 7, and 8 years old, milk production was measured, and weaning weights of their calves were compared.
