[Studies on the fertility of a number of A.I. bulls in herds of various sizes (author's transl)].
The inseminations carried out with semen collected from eight bulls were counted and arranged according to the size of the herds in which these bulls were used. A study of the figures shows that the conception rate attained by each bull decreases as the size of the herd increases. Evaluation of the fertility of a bull will therefore not only depend on semen quality but also on the management of the farm on which the bull is used.
