Method of identification of animals may formed of a good dairy of production, by analysis of the polymorphism of the genes pit - 1 and the kappa - casein

摘要

The present invention relates to methods and kits for determining the potential of milk production in an animal, from the analysis of the polymorphism of the genes pit - 1 and k - casein. More particularly, the invention relates to a method of identification of a mammal, which has a genotype indication of milk production lines, comprising a step of analysis of the polymorphism of the pit - 1 and k - casein of the mammal, in which the simultaneous presence of the hla- a and / or of the t allele pit - 1 and of the hla- b of the k - casein is indicative of high potentials of milk production, and for the production of milk proteins in a mammal.
