Effects of Treating Corn Stalk with Probiotics in Combination with Lime on Rumen Fermentation Characteristics in Northeast Fine-wool Sheep
摘要
Abstract
This experiment was conducted to study the effects of treating corn stalk with probiotics in combination with lime on rumen fermentation characteristics in Northeast fine-wool sheep. Four male sheep with permanent rumen fistula were used in a 4 ×4 Latin square design and fed with corn stalk ( group CK) , corn stalk treated with 6% lime ( group A) , corn stalk treated with probiotics ( group M) , and corn stalk treated with probiotics combined with lime ( group C) , respectively. Rumen pH, the concentrations of ammonia nitrogen ( NH3-N) , microbial crude protein ( MCP) and volatile fatty acids ( VFAs) were determined in this experiment. The results showed that the rumen pH of animals in the four groups were all in a normal range, and the differences among the four groups were not significant ( P >0. 05) ; the concentration of NH3-N and production of MCP in group C were significantly higher than those in group CK ( P < 0. 05) ; the concentration of total volatile fatty acids ( TVFAs) in group C was higher than that in the other groups at 2 and 4 h ( P >0. 05) ,but there were no significant differences in the average concentration of rumen TVFAs among the four groups ( P > 0. 05) . The results indicate that corn stalk treated by probiotics in combination with lime is more effective to improve rumen fermentation in sheep.
