In cows of the Belarusian black-motley breed, the polymorphism of genes for lactoferrin and mannose-binding leсtin was established. The genotypes LTF AA , LTF AB and MBL1 TT , MBL1 TC , MBL1 CC were identified. The milk productivity (yield, fat content, amount of milk of basic fat content), the number of somatic cells in milk were studied, and the economic efficiency of milk production from cows with different genotypes for the genes of lactoferrin and mannose-binding leсtin was calculated. It was found that the profit in cows with the LTF AA genotype was 7.91 rubles higher than in cows with the LTF AB genotype, in individuals with the MBL1 CC and MBL1 TT genotypes, and a higher profit per head was obtained from cows with the LTF AB MBL1 CC and LTF AA MBL1 TC genotypes, which amounted to 3249.49 and 2855.40 rubles respectively.
