The objective of this work was to compare the alternative methods to estimate the milk yield of cows from Gyr breed. A total of 3,632 lactations from of Gyr breed cows, from 1986 to 1996, were analyzed. The methods were: A – the morning milking control was performed in the odd months and the afternoon milking control in the even months – the yield of the morning milking control was multiplied by the multiplicative factor of the morning (MF) and […]
