Keyword:  饲料添加剂睾丸标志酶蓄积;
Abstract: 观察饲料添加剂的蓄积对雄性幼犬生殖发育的影响.选用12只1月龄土犬,随机分为试验组和对照组,试验组幼犬饲喂正常剂量日粮和高剂量组大鼠鼠肉,正常对照组幼犬饲喂正常剂量日粮和大鼠鼠肉,喂至幼犬成熟,检测雄性幼犬食用饲料添加剂高剂量组大鼠鼠肉后对其生长、生殖发育产生影响.检测幼犬睾丸标志酶活性,结果显示:试验组幼犬睾丸组织中酸性磷酸酶ACP和乳酸脱氢酶LDH的酶活性下降,碱性磷酸酶AKP活性未发生变化.试验组的酸性磷酸酶和乳酸脱氢酶活性明显下降,差异有统计学意义.推测饲料添加剂可能通过食物链的蓄积影响雄性幼犬的睾丸标志酶活性,从而影响雄性幼犬睾丸组织的正常生理功能,进一步影响幼犬的生殖功能.
