Effect of calving interval on assessment of breeding value in cattle. I. Effect of calving interval on 1st and 2nd lactations of German Brown cows in Bavaria



Effect of calving interval on assessment of breeding value in cattle. I. Effect of calving interval on 1st and 2nd lactations of German Brown cows in Bavaria



Bayerisches Landwirtschaftliches Jahrbuch 50(6): 643-651



305-day lactation records of all German Brown cows in Bavaria that had completed their 1st and 2nd lactations in 1969-1971 were examined. The overall mean values with SD for 28 332 cows were: calving interval (CI) 387 plus or minus 24 days; lactation length, 299 plus or minus 9 days; 1st lactation yield, 3304 plus or minus 620 kg; and 2nd lactation yield, 3919 plus or minus 757 kg.
