Short summary
The polymerase chain reaction (PCR) coupled with single-strand conformational polymorphism (SSCP) analysis was used to reveal variation in bovine leptin gene (LEP) in New Zealand (NZ) Holstein Friesian × Jersey (HF × J) dairy cows. This is the first report of findings of this kind in NZ HF × J cows, and they suggest that variation in exon 3 of bovine leptin gene could be explored as a means of decreasing the concentration of saturated fatty acids in milk.
