Effects of Different Feeding Modes on Meat Quality Characteristics in Guizhou Black Goat
摘要
Abstract
To explore the suitable breeding mode for high-quality meat goats in karst mountainous areas,Guizhou Black goats were used as the research object to study the effects of different feeding methods on their meat quality characteristics.Sixty 4-month-old Guizhou Black goats with healthy and similar body conditions were selected for the experiment and randomly divided into two groups.Two feeding modes were adopted,namely grazing+supplementary feeding(group A)and shed-feeding(group B).The two groups were fed with the same concentrate supplement until 12 months of age.Six goats with similar body weight were selected for slaughter in each group,and the longissimus dorsi muscle was taken for routine physicochemical indicators,meat quality,amino acids,and fatty acids determination.The results showed that the moisture content,crude ash content,and drip loss of Guizhou Black goat meat in group A were significantly higher than those in group B(P<0.05);the L* value of group B was significantly higher than that of group A(P<0.01),while the a*value,b*value,and crude fat content were significantly higher than those of group A(P<0.05),and there was no significant difference in pH45 min and crude protein content between the two groups(P>0.05).The total amino acid content and non essential amino acid content of group B were significantly higher than those of group A(P<0.01),and the difference in essential amino acid content between the two groups was not significant(P>0.05);the lysine content of group A was significantly higher than that of group B(P<0.01),while the glutamic acid and glycine content were significantly lower than those of group B(P<0.05),the histidine content was significantly lower than that of group B(P<0.01),and there was no significant difference in other amino acid content between the two groups(P>0.05).The palmitic acid(C16:0)content in group A was significantly higher than that in group B(P<0.01),while the oleic acid(C18:1n9c)content was significantly higher than that in group B(P<0.05);the content of stearic acid(C18:0)in group B lamb was significantly higher than that in group A(P<0.01),the content of linoleic acid(C18:2n6)was significantly higher than that in group A(P<0.05),and there was no significant difference in the content of other fatty acids between the two groups(P>0.05).In summury,the effects of grazing+supplementary feeding and shed-feeding on the quality characteristics of Guizhou Black goat meat were not significant,but the grazing+supplementary feeding mode could improve the meat flavor and taste.关键词
