Analysis of muscle nutrient composition and content of Zhedong white goose under the orange orchard geese grazing model
摘要
Abstract
The study was to analyze the changes in the composition and content of nutrients in the breast and leg muscles of Zhedong white geese under the orange orchard goose grazing model.A total of 300 one-day-old Zhedong white geese were raised to 21 days old were selected,and randomly divided into three groups,with five replicates per group,and 20 geese per replicate.The housing group was fed a basic diet,the grazing group was allowed to graze in the orange orchard all day and freely eat green grass,and the grazing+supplementary feeding group grazed in the orange orchard all day and was supplemented with a basic diet at fixed locations.The preliminary trial period was 20 days,and the formal experimental period was 50 days.The results showed that compared with the housing group,the moisture and crude protein content in the breast and leg muscles of the grazing group and the grazing+supplementary feeding group were significantly increased(P＜0.05),and the crude fat content was significantly reduced(P＜0.05).The content of aspartic acid in the breast and leg muscles of the grazing group was significantly increased(P＜0.05),and the content of glutamic acid in the leg muscles of the grazing+supplementary feeding group was significantly increased(P＜0.05).The content of saturated fatty acids(SFA)and monounsaturated fatty acids(MUFA)in the breast muscles of the grazing group were significantly lower than that of the other groups(P＜0.05),and the content of polyunsaturated fatty acids(PUFA)and essential fatty acids(EFA)were significantly higher than that of the other groups(P＜0.05).The content of SFA in the leg muscles of the grazing group was significantly lower than that of the other groups(P＜0.05),and the content of PUFA and EFA was significantly higher than that of the other groups(P＜0.05).The study indicates that the orange orchard goose grazing model can improve the meat quality of Zhedong white geese.关键词
