摘要: 试验随机选择4月龄的巫山黑山羊、波×巫F1、大足黑山羊、波×大F1公羔各9只,去势,强度育肥60天后,每个群体选择6只进行屠宰并对其进行肉品质特性研究。结果显示,(1)波×大F1肌肉中的总脂肪显著高于巫山黑山羊(P<0.05),灰分极显著低于巫山黑山羊和大足黑山羊(P<0.01),粗蛋白、胆固醇和水分在4个群体中差异不显著(P>0.05)。(2)各种氨基酸在大足黑山羊肌肉中的含量最高,波×巫F1次之,波×大F1最低;波×巫F1肌肉中的14种氨基酸含量较其母本有明显的上升趋势,而波×大F1 却有16种氨基酸明显低于其母本;波×巫F1中有5种必需氨基酸得分接近或超过100,其他群体中只有4种。(3)硬脂酸、棕榈酸和豆蔻酸在波×巫F1肌肉中的含量最高,油酸和亚油酸分别在波×大F1和大足黑山羊肌肉中的含量显著高于巫山黑山羊(P<0.05),大足黑山羊肌肉中的亚油酸占肌内脂肪的相对含量显著高于其杂交后代波×大F1(P<0.05)。(4)4个群体中的磷元素均明显高于其他元素,硒元素在波×巫F1肌肉中的含量最高,显著的高于在波×大F1肌肉中的含量(P<0.05),波×巫F1较其母本有7种元素呈上升趋势,而波×大F1则有5种元素较其母本明显降低。

Abstract: At the beginning, we randomly selected 9 of 4-month-old Wushan black goat, Boer ×Wushan black goat F1, Dazu black goat, and Boer ×Dazu black goat F1 respectively; after 60-day castration and strength fattening, we selected 6 lambs from each group for slaughtering and studies on meat quality characteristics. The results showed that: (1) Boer ×Dazu black goat F1 had higher total fat in muscle than Wushan black goat (P<0.05), and ash content was significantly lower than that of Wushan black goat and Dazu black goat (P < 0.01), but there was no significant difference in crude protein, cholesterol, and water of four groups (P > 0.05); (2) the content of various amino acids in Dazu black goat muscle was highest, the content in Boer ×Wushan black goat F1 was second highest , the content in Boer ×Dazu black goat F1 was minimum; 14 kinds of amino acids content in the muscle of Boer × Wushan black goat F1 had significantly improved than their female parent, while 16 kinds of amino acids in Boer ×Dazu black goat F1 was significantly lower than that of its parent; there were 5 essential amino acids score close to or more than 100 in Boer ×Wushan black goat F1, but other groups only had 4 essential amino acids; (3) there was highest stearic acid, palmitic acid and myristic acid content in the muscle of Boer ×Wushan black goat F1, oleic acid and linoleic acid content in Boer ×Dazu black goat F1 and Dazu black goat muscle were significantly higher than that of the Wushan black goat (P<0.05), relative content of linoleic acid in intramuscular fat in Dazu black goat muscle was significantly higher than that of the Boer ×Dazu black goat F1(P<0.05). (4) The phosphorus content was significantly higher than other elements in the 4 groups; selenium content was highest in muscle of Boer ×Wushan black goat F1, and significantly higher than the content in muscle of Boer ×Dazu black goat F1 (P<0.05). 7 kinds of elements were on the rise in the muscle of Boer ×Wushan black goat F1 than its parents, while 5 kinds of elements were significantly reduced in Boer ×Dazu black goat F1 than its parents.
