METHOD FOR IDENTIFYING ANIMALS FOR MILK PRODUCTION QUALITIESBY ANALYZING THE POLYMORPHISM OF THE PIT-1 AND KAPPA-CASEIN GENES

摘要

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