摘  要：
试验选用5只2岁、体重约40 kg的健康雄性哈萨克羊,单笼饲养。试验共4期(每期18 d,共72 d),第1期不添加棉酚,第2、3、4期在混合精料中分别添加984、13531、722 mg/d棉酚。结果表明,随着棉酚添加量的增加,试验羊的饮水量、排尿量、麦秸采食量、排粪量及粪中含水量无明显变化(P>0.05);抗利尿激素、肾素、皮质酮水平无显著变化(P>0.05),促肾上腺皮质激素、醛固酮水平在前3期呈下降的趋势,第4期与第3期相比显著上升(P<0.05);血清中Na+水平在2、3期明显下降(P<0.05),第4期恢复到第1期水平,血清中Cl-水平呈下降趋势,Ca2+水平也呈下降趋势,在4期试验中K+、无机磷、Mg2+含量无明显变化(P>0.05);尿中Na+、无机磷含量无变化(P>0.05),Cl-含量前3期上升,第4期恢复到第1期水平,K+、Mg2+、Ca2+含量第4期较前3期均显著下降(P<0.05)。

摘  要：
The present experiment was designed to feed 5 Kazak male sheep with gossypol of 0,984,1353 and 1722 mg/d respectively during the four periods,each period last 18 d,total 72 d.The results showed that water consumption,urine output,wheat straw feed intake,faecal output and the moisture content of feces of sheep were not significant change(P>0.05) with the amount of gossypol increasing;the level of antidiuretic hormone,rennin and cortisone didn't change significantly,the level of adreno cortieotropic hormone and aldosterone were both decline at the previous three periods,but increased during the fourth period compare to the third period(P<0.05);The level of Cl-and Ca2+ in serum decreased,and the level of Cl-of the third period was extremely significant lower than the first period(P<0.01).As for the Ca2+,the third period was significant lower than the first period(P<0.05),the level of K+,inorg-P,Mg2+ in serum didn't change significantly(P>0.05);the content of Na+ and inorg-P didn't change significantly(P>0.05),the content of Cl-was increased at the previous three periods,but the forth period return to the level of the first period,while the content of K+,Mg2+,Ca2+ of the forth period were lower than the previous three periods(P<0.05).
