摘要：

旨在研究西门塔尔杂种牛（西杂牛）肉用性能的利用。选用黑安格斯牛杂交西杂牛，随机选取同期出生断奶的杂交一代安西杂牛（黑安格斯♂×西杂牛♀）和西杂牛，在同一饲养管理条件下持续育肥至20月龄，屠宰安西杂牛和西杂牛公牛各9头，取其背最长肌，利用气相色谱法测定安西杂牛和西杂牛肌内脂肪酸组成及含量。结果表明，安西杂牛和西杂牛背最长肌中饱和脂肪酸（SFA）均达到52%以上，以长链棕榈酸和硬脂酸为主，安西杂牛中SFA显著低于西杂牛（P<0.05）；不饱和脂肪酸（UFA）占测定脂肪酸总量46%以上，安西杂牛中UFA极显著高于西杂牛（P<0.01）；单不饱和脂肪酸（MUFA）和多不饱和脂肪酸（PUFA）在安西杂牛和西杂牛中差异不显著（P>0.05），油酸的含量在安西杂牛中显著高于西杂牛（P<0.05），γ-亚麻酸、顺-11，14，17-二十碳三烯酸、顺-8，11，14-二十碳三烯酸、花生四烯酸和EPA等功能性脂肪酸在安西杂牛中显著高于西杂牛（P<0.05）。综上表明，与西杂牛相比，安西杂牛牛肉中脂肪酸的营养价值明显改善和提高。

Abstract:

The objective of this study was to discuss beef performances utilization of crossbred Simmental by crossbreeding crossbred Simmental with Black Angus. All of the first filial generation cattle (F₁) from Angus and crossed Simmental and crossbred Simmental (CS) were born and weaned during the same period and were selected randomly. They were fattened to 20 months of age under the same nutrition and management. Longissimus dorsi (LD) were collected from 18 bulls (9 heads of F₁and 9 heads of CS, respectively), and the component and content of fatty acids were detected by using the gas chromatography. The results showed that the content of saturated fatty acids (SFA) in F₁ and CS were both over 52% and palmitic acids and stearic acids were the major contribution to the long chain fatty acids in both breeds. SFA content was lower in F₁ than that in CS （P<0.05）. Unsaturated fatty acids (UFA) accounted for over 46% of the total fatty acids. The content of UFA was greater in F₁ than that in CS (P<0.01). The concentration of monounsaturated fatty acids and polyunsaturated fatty acids were not significantly different from F₁and CS (P>0.05). Oleic acids content was greater in F₁ than that in CS (P<0.05). Percentage of γ-linolenic acids, cis-11, 14, 17- eicosatrienoic acids, arachidonic acids, cis-8, 11, 14-eicosatrienoic acids and EPA were greater in F₁than that in CS (P<0.05). These results indicated that nutritional value of fatty acids from F₁could be improved when compared with CS.
