Hot topic: an association between a leptin single nucleotide polymorphism and milk and protein yield.

Journal of dairy science - 1 Oct 2003

Abstract excerpt

Allelic variation (C to T transition that results in an Arg25Cys) in the leptin gene has been associated with increased fat deposition in beef cattle. We report that this same genetic variant is also present in dairy breeds. Body fat reserves play an important role in sustaining high milk production in early lactation, when energy intake is limited. To test for an association between the leptin single nucleotide...
