Gene mannose binding lectin (MBL) and its influence of polymorphism on resistance of cows to mastitis

Numerous studies show that some genes are associated with animal productivity, product quality, and resistance to various diseases. In particular, such gene genotype as mannose-binding lectin (MBL1) is associated with milk productivity and quality of cow milk, as well as with resistance to mastitis. Studies of the Association of MBL1 gene polymorphism with economically useful traits of cows showed that alleles and genotypes in mbl1 gene are associated with milk productivity, milk composition and somatic cell content in milk. According to the results of the comparative analysis of Holstein heifers, the main indicators of milk productivity were the advantage in animals with the MBL1TC genotype. However, the content of somatic cells in milk favorably differed animals with genotype MBL1CC.
