摘要:

为了探讨日粮中棉酚含量对肥育肉牛血液指标和组织中棉酚残留的影响。本试验选取40头体况良好、平均初始体重为((454.37±42.42) kg)的利木赞杂交肉牛,随机分为4组,每组10头牛,分别饲喂4种不同棉酚含量的精饲料(对照组棉酚含量为98.28 mg•kg-1,低棉酚组棉酚含量为373.29 mg•kg-1,中棉酚组棉酚含量为644.60 mg•kg-1,高棉酚组棉酚含量为920.27 mg•kg-1),育肥期90 d。结果表明,日粮中棉酚含量增加对血常规、红细胞脆性、谷草转氨酶、谷丙转氨酶、谷氨酰基转移酶以及心、脾、肺、肾、肌肉、血清中的棉酚残留没有显著影响(P>0.05),但会显著提高血清尿素氮(P<0.05)及肝中的棉酚残留(P<0.05)。综合以上考虑成年肉牛对棉酚的抵抗力较强,日粮棉酚含量达到920.27 mg•kg-1不会对育肥肉牛生理造成伤害,但饲喂含棉酚日粮的牛的肝中棉酚残留均过多,不适宜食用。

Abstract:

The study was conducted to investigate the effects of different levels of gossypol in the diets on blood index and tissue residues of gossypol in fattening Limmonsin crossbred steers.Forty healthy steers with similar weight (454.37±42.42)kg were randomly allocated to 4 treatments with 10 replicates each and one steer in each replicate,precise feeding concentrates with different contents of gossypol(control group:98.28 mg•kg-1;low gossypol group:373.29 mg•kg-1;middle gossypol group:644.60 mg•kg-1;high gossypol group:920.27 mg•kg-1) during the 90 days finishing periods.The results showed that the different contents of gossypol in diet had no significant influence on blood routine,erythrocyte fragility,aspartate aminotransferase,alanine aminatransferase,γ-Glutamyl Transpeptidase Isoenzyme and gossypol residued in heart,spleen,lung,kidney,muscle, serum (P>0.05).But the different contents of gossypol in diet had significant effect on Serum urea nitrogen and liver residues of gossypol(P<0.05).In conclusion,adult steers own stronger resistance on gossypol,the gossypol content in diet reached 920.27 mg•kg-1 have no physiological damage,but feeding the diet with gossypol to steers,the gossypol residues in liver were too high for us to eat.
