公牛的自身免疫反应与精液品质的关系

为了进一步了解公牛在自身免疫学反应中对其本身精液品质的影响，本试验应用Kibrick和F-D法分别测定了不同季节和不同年龄公牛血液中抗精子抗体效价及对精子的凝集度。在相同的饲养条件下4头同龄公牛血液中抗体效价和凝集度夏季高，冬季低。而精子顶体完整率则是夏季低，冬季高。从年龄上根据试验分析，老龄公牛血液中抗体效价和凝集度均高，青年公牛低，中年公牛介于中间，精液品质中的顶体完整率老龄牛最低（成不可逆的），中年和青年公牛较高。

THE RELATIONSHIP BETWEEN SELF-IMMUNIZATION REACTION AND SEMEN QUALITY IN BULL

In order to study the influence of bull on semen quality of itself in self-immunization reaction, the titre of the anti-sperm antibody in blood and its agglutination degree to sperm in different season and age were detected respectively using Kibrick and F-D method in this experiment. Under the same feeding condition the titre of antisperm antibody and the agglutination degree in blood of the four same-aged bulls were low in summer but high in winter while the sperm acrosome integrity rate was low in summer but high in winter. According to the experiment the titre of the anti-sperm antibody and agglutination degree were highesht in old bull but lowest in the young. The middle-aged bull's was between them. The acrosome integrity rate was lowest in old bull (irreversible) and higher in young and middle-aged bull.
