Relationship of molecular breeding value for beef tenderness with heifer traits through weaning of their first calf.

Theriogenology - 1 Oct 2021

Abstract excerpt

Polymorphisms in μ-calpain (CAPN1) that beneficially associate with beef tenderness are reported to antagonistically associate with calving day in beef heifers and post-partum interval to estrus in beef cows. We, therefore, hypothesized that a molecular breeding value for slice shear force, calculated based on CAPN1 and calpastatin (CAST) genotypes, would demonstrate an antagonistic relationship between...
