ABSTRACT
The purpose of this study is to estimate genetic parameters of milk yield traits in Holstein and Brown Swiss cattle raised at two different State Farms. The heritability estimates of 305 days milk yield and lactation length were 0.21±0.06 and 0.06±0.04 for Holstein Friesian; 0.37±0.03 and 0.27±0.03 for Brown Swiss, respectively. The repeatability estimates of 305-days milk yield and lactation length were 0.36±0.03 and 0.22±0.03 for Holstein Friesian; 0.54±0.16 and 0.65±0.12 for Brown Swiss, respectively. It has been estimated that heritability of milk yield traits were moderate, repeatability of lactation length was high. Thus, high repeatability estimates are promising for opportunities for early selection practices.
