Trials were performed to determine the relationship of heparin-binding proteins (HBP) to fertility of bulls. Red Angus (142), Santa Gertrudis (59), Gelbvieh (59), and Santa Gertrudis x Gelbvieh (40) bulls were identified according to the presence or absence of the greatest affinity HBP (HBP-B5) on sperm membranes and in seminal fluid. Nine to 20 bulls with the same HBP-B5 profiles were assigned to pastures with Santa Gertrudis cows at a ratio of 1 bull:25 cows. Fertility for Group 1 (80 bulls with HBP-B5 in sperm membranes but undetectable HBP-B5 in seminal fluid, in six pastures) was 82% pregnant of 1,692 cows. Group 2 bulls (48 bulls with HBP-B5 detectable in seminal fluid and in sperm membranes, in four pastures) impregnated 67% of 919 cows. Fertility for Group 3 (37 bulls with HBP-B5 in seminal fluid but undetectable HBP-B5 in the sperm membranes, in three pastures) and Group 4 (56 bulls with undetectable HBP-B5 in seminal fluid and sperm, in four pastures) was 63% pregnant of 747 and 1,208 cows, respectively. Group 1 had an average of 17% greater fertility compared with Groups 2, 3, and 4 (P < .05). In conclusion, groups with the greatest affinity HBP-B5 in sperm membranes but not in seminal fluid had greater fertility than did groups with other HBP-B5 profiles.
开展了多项试验以确定肝素结合蛋白（HBP）与公牛生育力之间的关系。根据精子膜和精液中是否存在亲和力最强的HBP（HBP - B5），对红安格斯牛（142头）、圣格特鲁迪斯牛（59头）、盖尔维赫牛（59头）以及圣格特鲁迪斯牛×盖尔维赫牛杂交牛（40头）进行了鉴定。将9至20头具有相同HBP - B5谱型的公牛以1头公牛比25头母牛的比例分配到与圣格特鲁迪斯母牛同处的牧场。第1组（80头精子膜中有HBP - B5但精液中未检测到HBP - B5的公牛，分布在6个牧场）使1692头母牛中的82%受孕。第2组公牛（48头精液和精子膜中均可检测到HBP - B5的公牛，分布在4个牧场）使919头母牛中的67%受孕。第3组（37头精液中有HBP - B5但精子膜中未检测到HBP - B5的公牛，分布在3个牧场）和第4组（56头精液和精子中均未检测到HBP - B5的公牛，分布在4个牧场）分别使747头和1208头母牛中的63%受孕。与第2、3和4组相比，第1组的平均生育力高出17%（P < 0.05）。总之，精子膜中具有亲和力最强的HBP - B5但精液中没有的组比具有其他HBP - B5谱型的组生育力更高。
