Relationship between beta-lactoglobulin polymorphism and milk performance of HF cows

The study involved 180 Polish Holstein-Friesian var. Black-and-White cows with varied addition of HF genes managed for dairy purposes on a farm located in the Wielkopolskie voivodship. The beta-lactoglobulin genotypes (BLG) were identified using PCR-RFLP according to Medrano and Aguilar-Cordova with...

Summary:The study involved 180 Polish Holstein-Friesian var. Black-and-White cows with varied addition of HF genes managed for dairy purposes on a farm located in the Wielkopolskie voivodship. The beta-lactoglobulin genotypes (BLG) were identified using PCR-RFLP according to Medrano and Aguilar-Cordova with our modifications. We have found that BLG AA-genotype cows achieved the highest performance in terms of milk, fat, and protein yield both for the first and the second 305-d lactation. The highest protein content was found in the BB homozygotes. The highest milk fat content for the first lactation was observed in the BLG AA genotypes, while for the second lactation - in the BB homozygotes
