Abstract: | In order to explore different concentrations of mixed acids in improving quality of whole-plant corn silage and their effects on growth performance of Dorper×Han F1 sheep.4 levels of 45% formic acid,45% propionic acid and 10% sodium propionate were mixed,and 0(control),0.3%,0.6% and 1% were added to 4 groups of ripening period whole-plant corn.The results showed that compared with control group,the experimental groups could significantly decrease the proportion of AA/PA in silage (P<0.05);0.3% and 0.6% groups had the better effects.Based on the result of CNCPS,0.6% group significantly improved the PB3 component (P<0.05),reduced the CC component (P>0.05),and improved the quality of silage.Compared with control group,the experimental groups effectively inhibited the mold and yeast reproduction,improved the aerobic stability of silage.The feeding trial results showed that ADG and F/G of sheep in experimental groups were better than control group,and F/G of both 0.6% and 1% groups were significantly better than that in control group (P<0.05).In conclusion,treatment of mixed acids could improve the quality of whole-plant corn silage,and silage treated with 0.6% levels of mixed acids could significantly improve the growth performance of Dorper×Han F1 sheep. |
