| 摘 要： | 运用氨基酸自动分析仪测定了舍饲型合作猪肌肉中氨基酸的含量,结果表明:体重25～30kg,肌肉中氨基酸总量、必需氨基酸含量和鲜味氨基酸含量最高,其值为59.14%、25.70%、24.89%,赖氨酸的含量显著高于其余各组(p0.05),天门冬氨酸和苏氨酸的含量显著高于15kg～20kg和20～25kg(p0.05)、极显著高于10～15kg(p0.01),谷氨酸和亮氨酸的含量显著高于20～25kg(p0.05)、极显著高于10～15kg和15kg～20kg(p0.01);四段体重中苏氨酸、缬氨酸、异亮氨酸及蛋氨酸+胱氨酸为限制性氨基酸,蛋氨酸+胱氨酸为第一限制性氨基酸,EAA/TAA值高于40%,EAA/NEAA值高于60%,属于完全蛋白质。

| Abstract: | Automatic amino acid analyzer was used to determine amino acid contents in the muscle of different weight Hezuo pig under the condition of barn feeding. The results showed that content of total amino acids, essential amino acids and flavor amino acids of 25-30 kilograms were the highest, which were 59.14%, 25.70% and 24.89%, respectively. Lysine content was significantly higher than the other groups （P〈0.05）, Aspartic acid and threonine content was higher than 15-20kg and 20-- 25kg （P〈0.05） ,and was significantly higher than the 10-15kg （P〈0.01）. Glutamic acid and leucine were higher than 20-25kg （P〈0.05）, and was significantly higher than that of 10-15kg and 15-20kg （P〈0.01）. Threonine,valine,isoleucine and methionine ＋ cystine were the limited amino acid in four slaughter weight, methionine＋cystine was the first limited amino acid. Because EAA/TAA value was higher than 40% and EAA/NEAA value was higher than 60%, so it belonged to full protein. |
