Kansas Agricultural Experiment Station Research Reports
Spring and fall calving Angus (n==86) and Simmental (n==96) cows at three different locations in Kansas were used to evaluate the relationships between milk production, Milk Expected Progeny Difference (Milk EPD), and calf weaning weight. A change of 1 lb in Milk EPD resulted in 4.95 lb change in calf weaning weight in Angus and 4.60 lb in Simmental. Each lb increase in Milk EPD predicted a 69.87 lb increase in total lactation milk production in Angus and 70.741b in Simmentals. Positive correlations were .40 and .64 between Milk EPD and total milk produced per lactation and .24 and .49 …
