Estimation of heritability and repeatability of milk yield of Brown Swiss cattle reared in Ulas State Farm*

Suleyman Cliek, Mehmet Emin Tekin

Abstract


In this study, heritability and repeatability of milk yield were estimated for Brown Swiss cattle. From 2 652 lactations, repeatability of milk yield was estimated as 0.52±0.02. Heritability of milk yield for all lactations was estimated as 0.24±0.05 from 2 820 lactation records. It was concluded that both the repeatability and the heritability were at expected levels and these results can be used for selecting and culling of the cattle in this farm.
