选择24只辽宁绒山羊羯羊,年龄10月龄,初始体重37.21±0.45 kg。试验动物分成3组,1组、2组为试验组,3组为对照组。研究育肥羯羊羊肉常规营养指标、各类脂肪酸和氨基酸含量。结果表明:试验1、2组粗脂肪显著高于对照组(P<0.05);试验1组粗灰分显著高于对照组(P<0.05)。在脂肪酸方面,试验1组总体上高于对照组或与对照组持平。试验1组C8:0、C14:1、C16:1、C22:1n9均显著(P<0.05)高于对照组;试验1、2组C18:1n9c、脂肪酸总量、SFA、MUFA、CLA均极显著高于对照组(P<0.01)。在氨基酸方面,对照组各氨基酸和总氨基酸总体上高于2个试验组;而试验1组又略高于试验2组。在必需氨基酸中,试验2组苏氨酸显著(P<0.05)高于对照组,试验1组氨基酸评分、E/T和E/N均高于对照组。因此,高能高蛋白日粮育肥羯羊可使羊肉粗脂肪含量、不饱和脂肪酸和总脂肪酸含量极显著增加,对羊肉必需氨基酸含量和构成比例有改善作用。
Nutrient characteristics of meat in fattening Liaoning Cashmere Wether Goat
Twenty-four Liaoning Cashmere Wether Goats were randomly divided into three groups, feeding with number 1 to 3 ration. All the Wether goat were investigated normal nutrients ingredi-ents, fatty acids, and amino acids in meat. The results showed crude fat(EE%)in test 1 and 2 were all significantly(P<0.05) higher than the control, and crude ash(Cash%) in test 1 was significant (P<0.05) higher than the control. As a whole, the fatty acids in test 1 were higher than (or equal to ) the control. And C8:0,C14:1,C16:1,C22:1n9 in test 1 were all significant(P<0.05) high-er than the control;and C18:1n9c, total fatty acids,SFA、MUFA、CLA of meat in test 1 were all ex-tremely significantly(P<0.01) higher than the control;C18:1n9c, total fatty acids,CLA in test 2 were significantly(P<0.05) higher than the control. The amino acids in the control in the mass was higher than test 1 and test 2, while threonine in test 2 was significant(P<0.05) higher than the control. Essential amino acid score(AAS), E/T,E/N in test 1 were all higher than the control According to the results it could been summarized that crude fat, PUFA and total fatty acids were increased, and essential amino acid score(AAS), E/T, E/N were all increased, the amino acids were improved after fattening.
