Genetics of reproductive performance in seasonal calving beef cows and its association with performance traits
DP Berry, RD Evans - Journal of Animal Science, 2014 - academic.oup.com
Due primarily to a lack of phenotypic data, little research has been undertaken on the
genetics of reproductive performance in beef cattle. The objective of this study was to …
