和牛血液生化指标与肉品质的相关性分析
Correlation between blood biochemical indexes and meat quality in Wagyu cattle
摘要
Abstract
The aim of this paper was to analyze the relationship between blood biochemical parameters and meat quality of Wagyu cattle.Forty-five 60-month-old Wagyu cattle(372.3±40.2)kg were selected.Their blood biochemical indexes were measured and their meat quality was graded.The differences between the blood biochemical indexes of Wagyu cattle of different meat quality grades were analyzed by one-way ANOVA,and the entropy value method was used to evaluate the Wagyu cattle of different meat quality grades using the significantly different blood biochemical indexes as evaluation indexes.The results showed that the contents of cholinesterase(CHE),potassium(K)and free fatty acids(NEEA)were different among blood biochemical indicators in the Wagyu cattle of different meat quality grades,with CHE highly significant(P＜0.01)between grades A2,A3 and A4,K highly significant(P＜0.01)between grades A2 and A4,A3 and A4(P＜0.05),and NEFA highly significant(P＜0.01)between grades A2,A3 and A4.The differences in CHE,K and NEFA index scores and the overall scores of A4 meat grades and cattle were significantly higher than those of A2 and A3(P＜0.01).There were significant differ-ences between the blood biochemical indexes of Wagyu cattle of different meat quality grades,and the blood biochemical indexes of Wagyu cattle can reflect their meat quality to a certain extent.关键词
