Document Summary

Same pasture, kennel, cage, sex, year, etc. Ebv estimated breeding value *** read detailed sheet on how to ebvs. ~ creating a similar life for the phenotype you are evaluating. ~ animals raised on pasture last yr are going to have a different growth pattern than those raised this yr. Same e = (cid:498)contemporaries(cid:499) (cid:523)as close to the individuals w. phenotypes expressed(cid:524) Calculate deviation from group average contemporary deviation. *each animals deviation includes the group average (cid:523)don"t have to calculate new for each(cid:524) ~ comp animal breeders don"t have the same resources that cattle breeders do (cid:498)contemporaries(cid:499) factors that affect p (ie. e) (p = g + e) ~ ie. drought 1 year compared to next yrs growth rates. ~ want compare on the same track, same day, etc. ~ if it rained one day, footing would be different for the horses. Track/course (~racing on diff lengths, track ground) Ebvs a sample (aka selection index or blp)
