Abstract

Measuring ancestry levels of local admixed cattle in Sri Lanka provides insight on the most suitable dairy (cross)breeds for the local environment. Performance data of dairy cows (n=197) as well as blood samples for genotyping were collected from two governmental farms in the Kurunegala District in Sri Lanka. Admixture levels were calculated as proportional abundance of the Jersey, Holstein Friesian, and Sahiwal ancestry. The dominance component of heterosis was determined by calculating the abundance of non-homozygous genetic blocks. A mixed linear model was applied to find how performance and admixture levels were associated. For 305-day milk yield, significant predictors were found for Jersey ancestral breed proportion and the dominance component of heterosis for P
