Abstract

In this study, milk yield parameters of Holstein Friesian cows raised at Koçaş State Farm were investigated. The means of lactation milk yield, 305 d milk yield, lactation length and dry period were found as 7046.18 kg, 6588.38 kg, 327.37 d and 67.48 d respectively. Also, estimated heritability‘s of same traits were as 0.25, 0.26, 0.07 and 0.03 respectively. The effects of year, season and lactation number on lactation milk yield, 305 d milk yield and lactation length; the effects of calving season and lactation number on dry period were found significantly. In conclusion, data of milk yield traits of Holstein Friesian cows in raised Koçaş State Farm herd were determined well condition within reasonable ranges.
