Effect of Different Replacement Ratio of Soybean Meal by Compound Protein Pellet on Rumen Fermentation and Blood Biochemical Traits in Sheep
The experiment was conducted to study the effects of different replacement ratio of soybean meal by compound protein pellet on rumen fermentation and blood biochemical rraits in sheep. Four crossed - bred ( Charolais X Dorset ) sheep with an average weight of ( 50 ± 2) kg were used in a 4 x 4 Latin square design. The control group was fed the basal diet, and group I to group Ⅲ were fed the basal diet in which 40% , 60% and 80 % soybean meal were replaced with compound protein pellet The results showed that there were no significant effects on ruminal pH value (P>0. 05) , the variety trends of pH value have delayed as the concentration of compound protein pellet supplement increasing. The experimental groups compared with the control group, the NH3 - N concentration increased by 4.66% ,15. 27% ,21. 05% , the experiment group H were distinctly difference compared with control group (P <0.05). The groups showed no difference of the volatile fatty acids concentration(P >0. 05), however, the variety trends have decreased; and the A/P ratio of the experiment group Ⅲ was higher than others groups(P>0. 05); the groups showed no difference of BUN,, URIC, CREA ( P > 0.05 ) , however, the ALT and ALP of the experiment groupⅢ were higher than control group ( P > 0. 05 ) , AST was also significantly higher than other groups (P >0. 05). In conclusion, compound protein pellet substituted for soybean meal have no significant effects on rumen fermentation, substituted for 80% soybean meal had a certain influence on liver function in sheep, from the security and economic considerations, compound protein pellet substituted for 60% soybean meal was better, and it was no significant effect on rumen fermentation and blood biochemical indicators.
