Relationship Between Expected Progeny Differences (Epd) And Performance Of Angus And Simmental Bulls In Central Bull Tests, D.D. Simms
Kansas Agricultural Experiment Station Research Reports
The performance of bulls (n = 656 for Angus and n = 1343 for Simmental) at the Beloit and Potwin bulls tests from 1989 to 1992 were compared to their expected progeny differences (EPDs). In general, correlations between on-test ADG and weaning and yearling EPD were low for both breeds. However, the correlations between actual yearling weight and yearling EPD was moderate for Angus. Differences in actual yearling weight were 2.80 and 1.71 pounds (for Angus and Simmental, respectively) for each pound of difference in yearling weight EPD, which is close to the 2.0 pound difference expected. Thus, although the …
Factors Influencing The Price Paid For Bulls At Central Test Stations In Kansas From 1988-1992, D.D. Simms, J.R. Schwenke
Factors Influencing The Price Paid For Bulls At Central Test Stations In Kansas From 1988-1992, D.D. Simms, J.R. Schwenke
Kansas Agricultural Experiment Station Research Reports
Results of 13 sales of Angus (n=185) and Simmental (n=544) bulls at central bull tests in Kansas from 1988 through 1992 were analyzed to determine the relationship between performance and the price received. The Kansas bull test index (based 50% on weight per- day-of-age and 50% on test ADG) was the most significant single factor determining price in both Angus and Simmental bulls. Birth weight, final weight, and frame score were other major contributors to price in Angus bulls, whereas weaning weight ratio, birth weight, and being polled were important in Simmental bulls. Expected progeny differences made small but significant …
