Abstract:

The objective of this experiment was to study the effects of dietary supplement of fermented corn straw (fermented by bacillus subtilis, lactic acid bacteria and saccharomycetes) on production performance, nutrients digestibility, and methane emission for mutton sheep. 30 ram lambs (Dorper × Small tailed han sheep, F1) were randomly allotted to two dietary treatments supplemented with 0 (control group) and 27.5% fermented corn straw(experimental group), forage-to-concentrate ratio was 45:55.The results indicated that feeding fermented corn straw could significantly increase the ADG and nutrients digestibility of sheep; the methane emission of experimental group decreased 21.5% compared with control group by using respiration calorimetry unit. In conclusion, microbial fermentation could improve straw quality, and feeding this fermented corn straw could enhance the production performance and nutrients digestibility of mutton sheep, and significantly decrease the methane emission and methane energy.

Key words: fermented corn straw; fattening sheep; production performance; digestibility; methane emission
