Method for identifying animals for milk production qualities by analysing the polymorphism of the Pit-1 and kappa-casein genes

摘要

Methods and kits for determining milk production potential in an animal by analyzing the polymorphism of its Pit-1 and kappa-casein genes. More particularly, the invention concerns a method for identifying a mammal with a genotype that is indicative of advantageous milk production traits, including a step for analyzing the polymorphism of the Pit-1 and kappa-casein genes of the mammal, in which the simultaneous presence of allele A and/or T of the Pit-1 gene and allele B of the kappa-casein gene is indicative of high potential for milk production and protein production in the mammal.
