Genetic variance components for alternative definitions of fatty acids in dairy cow milk expressed either as a concentration or yield.

Abstract excerpt

The extent of genetic variability in fatty acids in bovine milk has, to date, generally focused on its concentration in either milk or milk fat. Selection for ratio traits, such as fatty acid concentration, is statistically and biologically problematic because it can distort relationships between component traits and lead to unintended genetic responses. The objective of this study was to explore the degree of...
