dc.description.abstract |
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 between Milk EPD and calf weaning
weight for Angus and Simmental, respectively. Milk EPDs can be used as genetic selection
tools to influence milk production levels and make corresponding changes in calf weaning
weights. |
