Association between markers at the leptin gene and carcass traits in bulls and heifers fed commercial batch

摘要

Association between markers at the leptin gene and carcass traits in bulls and heifers of batch of food trade.The present invention provides a method for subgrupar animals according to the genotype of the animals of each group have a similar polymorphism or combination of polymorphisms in the leptin gene, the simple nucleotide polymorphisms being selected group which consists of uasms1, Uasms2, uasms3, Exon2 - FB and e2jw.The combination of single nucleotide polymorphisms of leptin gene, especially combinations comprising alleles of the locus of e2jw, may also indicate an increase in the tenderness of the meat, but also indicate the quality of other features of the animals.The invention also provides methods for identifying an animal having a desirable phenotype on the right amount of feed, growth rate, body weight, merit and carcass composition and yield of milk, when compared to the general population of animals of that species.Comprising determining the presence of a polimodismo nucleotide single or combination of single nucleotide polymorphisms in the leptin gene of the animal.
