中草药添加剂饲喂猪肉中CPK,GPI活性和肉质关系的研究

 对添加中草药和常规抗生素试验猪的背最长肌进行相关酶测定,发现磷酸肌酸激酶（CPK）,磷酸葡萄糖异构酶（GPI）的活性,试验组明显高于对照组,分别提高了30.54%和20.04%（P＜0.05）.屠宰及肉质试验表明,试验组的瘦肉率及眼肌面积分别比对照组提高5.79%和8.48%（P＜0.05）,而脂肪率、膘厚、失水率和贮存损失则分别下降31.40%,28.21%,50.03%和20.35%（P＜0.05）.

Effect of Chinese Herb Feed Additives on the Activities of CPK and GPI and Meat Qualities of Growing and Finishing Pigs

160 growing and finishing pigs (Duroc×Landrace×Yorkshire,20 kg initially)were assigned into control and treated group set with four replicate pens per treatment by weight and sex. Fed basic diet supplemented with Chinese herb feed additives or antibiotic. The results showed that comparing to control group, the Chinese herb feed additives was increased the activities of CPK and GPI in the Longissimus dorsi muscle of the treatment pigs by 30.54% and 20.04% respectively (P＜0.05). The lean meat percentage and rib-eye areas of treated pigs increased by 5.79% and 8.48% respectively（P＜0.05）. The percentage of dissected fat of carcass, the mean backfat depth , the water lose ratio and the ratio of storing lose of treated pigs decreased by 31.40%, 28.21%, 50.03% and 20.35% respectively (P＜0.05).
