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.
