Genetic and Economic Implications of Single Trait Selection for Protein and Solids-Not-Fat

Studies on dairy production of milking ewes. I. – Estimates of genetic parameters for total milk composition and yield

“…The corrected variables (CM, CF and CP) were more heritable than the original variables (M, F and P) (table 3) and reported by others since that time (D EB et al, 1974 ;ToNG et al, 1976 ;H ARDIE et al, 1978 ;H ARGROVE et al, 1981 ;D ANELL , 1982 composition in dairy ewes are known to us. These estimates were obtained from two experimental flocks in the Sarde breed.…”
