Abstract excerpt
Twinning rate was analyzed in the Israeli Holstein dairy cattle population by the multiple-trait animal model, and a daughter design genome scan for quantitative trait loci was performed. Each parity was considered a separate trait. Heritabilities of twinning rate were very low, but increased by parity from 0.01 in first parity to 0.03 in fifth parity. All genetic correlations among parities were >0.77, but all...
