Associations of serologically defined BoLA class I alleles with milk production traits in three Swiss cattle breeds

The associations between the bovine MHC (BoLA) class I region and milk production traits in three Swiss cattle breeds was subject of investigation. The data set included 598 Braunvieh × Brown Swiss, 629 Simmental × Red Holstein, and 195 Holstein AI test bulls. A gene substitution model was used to a...

Summary:The associations between the bovine MHC (BoLA) class I region and milk production traits in three Swiss cattle breeds was subject of investigation. The data set included 598 Braunvieh × Brown Swiss, 629 Simmental × Red Holstein, and 195 Holstein AI test bulls. A gene substitution model was used to analyse the influence of BoLA haplotypes on deregressed breeding values of bulls for milk production. In Braunvieh crosses, the BoLA class I alleles were related to the amount of fat produced per lactation. Allele A22 was associated with a high fat production. In Fleckvieh and Holstein bulls, no significant effect on milk production traits was found.
