Effects of Corn Straw Silage Ensilaged Using Different Methods on Slaughter Performance, Tissue and Organ Development and Serum Biochemical Indices of Mutton Sheep
摘要
Abstract
This experiment was conducted to investigate the effects of effects of corn straw silage ensilaged u-sing different methods on slaughter performance, tissue and organ development and serum biochemical indices of mutton sheep. Eighty Dorper×small-tailed Han crossbred F1male lambs with initial body weight of(24.00± 2.42)kg were randomly divided into four groups with five replicates in each group and four lambs per repli-cate. Lambs in different groups were fed dried corn straw(blank control group,BC group),corn straw silage without additive(group Ⅰ), corn straw silage with enzyme-bacteria preparation(group Ⅱ)and Chinese wildrye(Chinese wildrye control group,CC group)as roughage,respectively. The experiment consisted of an 8-day of pre-trial period and a 60-day trial period. The results showed as follows: 1)dry matter intake, live weight before slaughter(LWBS), carcass weight of group Ⅰ and group Ⅱ were significantly higher than those of BC group(P<0.05),and feed/gain was significantly lower than that of BC group(P<0.05);dress-ing percentage of group Ⅱ was significantly higher than that of BC group(P<0.05), feed/gain was signifi-cantly lower than that of group Ⅰ(P<0.05); no significant differences were found in carcass weight and dressing percentage among groupⅠ,groupⅡand CC group. 2)Except liver and rumen weight of groupⅠ, group Ⅱand CC group were significantly higher than those of BC group(P<0.05),no significant differences were found in other tissue and organ weight, as well as their percentage of LWBS(P>0.05). 3)No signifi-cant differences were found in serum biochemical indices among groups(P>0.05). In conclusion,feeding val-ue of corn straw silage was improved after enzyme-bacteria preparation treatment,which has the same effects in promoting growth, tissue and organ development of mutton sheep compared with Chinese wildrye.关键词
