Breeding and Genetics: Dairy Genetic Evaluation
نویسندگان
چکیده
Due to the lower DMI, the IH200 heifers had lighter final weight and lower ADG on a live basis (P<.01) than the IHFH heifers, but these differences were reduced on a carcass-adjusted basis. The IH200 heifers had significantly improved feed conversion compared to FH and R200 (P = 0.01) and tended to have better feed conversion than IHFH (P = 0.14) on a carcass-adjusted basis. The IH200 heifers had significantly higher dressing percent, less rib fat, larger ribeye area, lower average yield grade, greater percentage yield grade 1 & 2, lower EBF, and heavier predicted weight at 28% EBF than any other treatment (P < 0.01). These data indicate that Revalor-200 may improve performance and EBF-adjusted final weight compared to Finaplix-H in either single or reimplant strategies utilized in yearling heifers.

As for any species or population, genetic improvement of dairy cattle involves determining a desirable direction for improvement, identifying traits that provide information to move in that direction, quantifying their heritability, deciding how to evaluate them, and designing a breeding program to achieve the goals. With regard to these issues, dairy cattle are one of the most highly studied o...
