The mean generation interval of the flock is 5. 42 years of the current breeding scheme, and the ratio of input and output is 1∶11. 50, but the rate of mammitis will increase at the speed of 2%, at the same time, the number of daughters and sons of test bulls is not large enough for good accuracy for estimating test bull breeding value, so the breeding scheme in effect need to be improve.

D、在影响育种效益的诸因素中，单一的加大群体规模、育种群比例以及每年选留测验公牛数将在一定程度上提高育种效益和遗传进展，但随选留种子公牛数提高将降低育种效益和综合育种值遗传进展；在育种实践中应尽量扩大育种群规模和主动育种群比例。
