波尔山羊与南江黄羊杂交一代产肉性能和肌肉品质研究

随机选择相同放牧条件下的 6只波尔山羊与南江黄羊的杂交一代 (BN) (3♂、3♀ )以及同龄的南江黄羊 (NN)(3♂、3♀ )于八月龄进行屠宰 ,结果表明 ,BN的平均宰前活重、胴体重、胴体产肉率、肉骨比等指标均显著或极显著地高于NN(0 0 1

0 0 5 )。BN肌肉蛋白质中的氨基酸种类齐全 ,含量丰富 ,赖氨酸、苯丙氨酸、和蛋氨酸等人体必需氨基酸的含量还有所提高。

Studyies on the Meat Performance and Meat Quality of Hybrids of Boer Goat with Nanjiang Yellow Goat

Under the same extensive grazing conditions, six hybrids of Boer goat with Nanjiang Yellow goat (BN, 3♂, 3♀) and six contemporary Nanjiang Yellow goat (NN, 3♂, 3♀) are slaughtered at the age of eight months. The results show as follows: ①The quality of BN's carcass improves obviously. BN is higher than those of contemporary NN significantly or very significantly (0.010.05) between BN and NN in some physical traits and normal chemical compositions, such as water loss, drip loss, mature percent, shearing force value, fiber diameter and the content of water, cure protein, cure fat and ash etc. ④The types and contents of amino acid in BN's meat are rich. BN's meat is higher than those of NN in content of some essential amino acids such as lysine, phenylalanine and methionine.
