Effect of milk yield level on some fertility indices in Polish Black-and-White Lowland cows



Effect of milk yield level on some fertility indices in Polish Black-and-White Lowland cows



Zeszyty Naukowe Akademii Rolniczo Technicznej w Olsztynie (129 (Zootechnika 6)): 179-188



Milk yields and fertilities of 663 Polish Black-and-White Lowland cows on 20 state breeding farms in Olsztyn province (Poland) covering 1st-4th lactations (2271 lactations) in 1962-1969 were considered. The results are tabulated in detail. A significant effect of max. daily milk yield on length of calving interval was found only in the 1st lactation, heifers with a max. yield of less than or equal to 15 kg having the longest interval.
