Ma. Arriens et al., ASSOCIATIONS OF SEROLOGICALLY DEFINED BOLA CLASS-I ALLELES WITH MILK-PRODUCTION TRAITS IN 3 SWISS CATTLE BREEDS, Livestock production science, 45(2-3), 1996, pp. 163-169
The associations between the bovine MHC (BoLA) class I region and milk
production traits in three Swiss cattle breeds was subject of investi
gation. The data set included 598 Braunvieh x Brown Swiss, 629 Simment
al x Red Holstein, and 195 Holstein AI test bulls. A gene substitution
model was used to analyse the influence of BoLA haplotypes on deregre
ssed breeding values of bulls for milk production. In Braunvieh crosse
s, 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 product
ion traits was found.
