B.1 Comparison of the same period and age Method B (normative supplement) Method for calculating breeding value of breeding bulls The table summarizes the calculation of the number of times of milking, the selected bulls (about 18 months old) are randomly selected within ? months, and the 5th mate of the cows is generally required to wait for their offspring to be born. 3.2 Method for calculating the relative commercial breeding value of breeding bulls B2.1 First calculate the comparison value of the same age in the company. The weight difference between the tested bull and the last generation of the secret bull is calculated with the weight difference of one year old as the comparison standard. The number of all effective generations of the tested bulls in the early stage of maturity (2: weighted average difference (DW) is calculated by dividing the weighted average of the tested bulls and other bulls in the later batches. This number of generations is combined with the average number of the whole body, which is the breeding value of the bull in this category. Its breeding value is a percentage of the herd average, which is the general breeding index of this bull. 2.2 Calculation formula:
B..2.1 Weighted average formula (B1): NN.
W is the weighted average difference between the tested bulls and the bulls of the same period and age. W..-- - Number of effective offspring, namely: N or bull generation efficiency;
