Effects of Ear Corn Silage on Growth Performance and Pork Quality of Growing-Finishing Pigs
To investigate the effects of dietary ear corn silage on growth performance,carcass traits and meat quality of growing-finishing pigs,192 Duroc×Landrace×Yorkshire commercial pigs with similar age and 36.82±1.50 kg of initial body weight were randomly divided into control group and experimental groups(Ⅰ,Ⅱ,Ⅲ)with 4 replicates per group.The control group was fed with the basic feed,while the experimental groups were fed with three kinds of experimental feed containing 15%,30%and 45%ear corn silage respec-tively during the growth stage(54 days),and three kinds of experimental feed containing 23%,46%and 69%ear corn silage respectively during the finishing stage(62 days).The results showed that ear corn silage diet had no significant effects on carcass traits and muscle quality of growing-finishing pigs.The average daily gain of the control group and group Ⅲ during the entire period were significantly lower than that of group Ⅰ(P<0.05),and the other growth performance indexes had no significant differences.Compared with control group,the muscle linoleic acid content in group Ⅲ was significantly increased by 36.22%(P<0.05),and the crude fat content was significantly lower than that of control group and group Ⅰ(P<0.05).In conclusion,the appropriate ear corn silage content at growth and finishing stages were 15%～30%and 23%～46%,respective-ly,which could provide data support for its promotion and application in growing-finishing pigs.
