Some factors affecting milk yield and lactation period in Holstein Friesian cows



Some factors affecting milk yield and lactation period in Holstein Friesian cows



Dirasat Agricultural Sciences 31(1): 39-45



Breeding and production records collected from the Holstein-Friesian herd (black-white and red-white) of The Nasr Dairy Cattle Station, central Iraq, were analysed by the least squares method. The analysis included 4487 lactations produced during 1998-2000. A total of 1250 pregnant heifers were utilized for this study. The effects of some non-genetic factors on total milk yield and lactation period were investigated.
