摘要&本研究旨在比较牦牛、犏牛和黄牛生产性能、肉营养品质及风味物质的差异。选取青海省海南州自然放牧、年龄相近的牦牛、犏牛和黄牛公牛各13头,分别进行体尺和屠宰性能的测定,采用国标方法进行常规营养成分、氨基酸和脂肪酸含量的测定,采用高效液相色谱法进行肌苷、肌苷酸和硫胺素含量的测定,采用高氯酸滴定法进行谷氨酸钠含量测定。结果表明:1)在体重、体长、体高和胸围以及宰前重、头重、皮重、前二蹄重、后二蹄重、胴体重、胴体肉重、胴体骨重上,犏牛均表现出突出的杂种优势。2)牦牛、犏牛肉具高蛋白质、低脂肪的特点;犏牛、牦牛肉中氨基酸丰富;犏牛肉多不饱和脂肪酸的含量显著高于牦牛和黄牛(P&0.05),犏牛、牦牛肉中单不饱和脂肪酸含量均显著高于黄牛(P&0.05)。3)牦牛肉中肌苷含量最高,显著高于同龄黄牛(P&0.05);肌苷酸的含量在3品种间无显著差异(P&0.05);犏牛肉硫胺素的含量显著高于黄牛(P&0.05);黄牛、犏牛肉谷氨酸钠的含量显著高于牦牛(P&0.05)。综上所述,与牦牛和黄牛相比,犏牛具有突出的杂种优势,犏牛肉具有高蛋白质、低脂肪的特点,氨基酸、不饱和脂肪酸和风味物质也更为丰富。

Abstract：
This study was conducted to compare the differences of performance, nutritional quality and flavor compounds in beef of yaks, cattle-yaks and cattle. Yaks, cattle-yaks and cattle (13 heads per breed) with similar age, naturally farmed in Hainan state, Qinghai province were selected. Body measurements and slaughter perform the contents of regular nutritional components, amino acids and fatty acids were determined by natio the contents of inosine, inosinic acid and thiamine were determined by high performance l and sodium glutamate content was determined by perchloric acid titration. The results showed as follows: 1) cattle-yaks showed extrusive hybrid vigor on body weight, body length, body high and bust circumference, as well as the weight before slaughter and the weight of head, skin, two fore hoofs, two hind hoofs, carcass weight, carcass meat and carcass bone. 2) Yaks and cattle-yaks had the characteristics of high the beef of yaks and cattle-yaks was the content of polyunsaturated fatty acids in beef of cattle-yaks was significantly higher than that of yaks and cattle (P&0.05), and the content of monounsaturated fatty acids in beef of yaks and cattle-yaks was significantly higher than that in cattle (P&0.05). 3) Inosine content in beef of yaks was the highest, and was significantly higher than that of cattle (P&0.05); there was no significant difference in inosinic acid content among the three breeds (P&0.05); the content of thiamine in beef of cattle-yaks was significantly higher than that of cattle (P&0.05); the content of sodium glutamate content in beef of cattle and cattle-yaks was significantly higher than that of yaks (P&0.05). In conclusion, compared with yaks and cattle, cattle-yaks have ex the beef has the characteristics of high protein and low fat, and the contents of amino acids, unsaturated fatty acids and flavor substances are more rich.

天然白水牛角并非纯白色，有象青玉、黄玉、白玉色，角尖部分厚实颜色多沉着泛青并伴有白色年轮纹路和黑色血丝纹路，角筒部分稍薄颜色通透多伴有黑色血丝纹路，极少数牛角整体或者部分颜色泛红，如果您有缘遇到这是您的福份，这就是传说中的赤牛（红牛）角，就是赤化或者半赤化的水牛，非常稀有和珍贵。天然白水牛角材质细腻温润，外观晶莹剔透，还是目前唯一能替代犀牛角入药的名贵中药材，有玉石的外观和犀角的药效。
黑水牛角梳或刮痧板一般色泽明亮，反光度好，若有白色的粉末则是角梳打磨过程中的粉末，轻轻擦拭即可；可以看到有点不明显的做工痕迹；工艺好的牛角梳手感温润，厚实。
