Document Summary
Milk + growth = combined material or total maternal (same things) *talks about bull"s influence when breed to a group of cows- directly using the bull. Predicts differences in the % of unassisted births when a bull is bred to first-calf, 2-year- old heifers. Example: bull a = 10 and bull b = 2 difference is +8: you would expect to have to pull 8% more calves from heifers breed to bull b than. *talks about when using a bull, you look at the trouble his daughters will then have. Predicts differences in daughters of bull aka tells us how much trouble the daughters will calve. Use bull, and determine how much trouble his daughters are going to have when calving. Example: bull a = 10 and bull b = 2 +8. Larger # related to lower age at puberty in daughters: daughters tend to go through puberty at an earlier age and can get heifers bred faster.
