【摘要】:【目的】研究柯爾克孜羊的肉品質(zhì)特性和影響因素,為柯爾克孜羊種質(zhì)資源保護(hù),為合理開發(fā)柯爾克孜羊和組織生產(chǎn)提供科學(xué)的理論依據(jù)!痉椒ā恳孕陆聽柨俗窝驗檠芯繉ο,研究相同圈養(yǎng)條件下,柯爾克孜羊7個月齡和20個月齡公羊和母羊骨骼肌常規(guī)營養(yǎng)成分、理化指標(biāo)、礦物元素含量、氨基酸含量等成分的含量。【結(jié)果】不同年齡對新疆柯爾克孜羊骨骼肌中粗脂肪、粗灰分、粗蛋白、羊肉嫩度、鐵、鋅、鈣、鎂、銅等礦物質(zhì)含量、氨基酸組成和氨基酸總量等營養(yǎng)成分含量有顯著(P0.05)或者極顯著的影響(P0.01)!窘Y(jié)論】隨著年齡的增長,柯爾克孜羊骨骼肌蛋白、脂肪、無機(jī)物、鋅、鈣、鎂、銅等礦物元素、氨基酸種類和數(shù)量越豐富,而嫩度卻降低,屠宰2 h后羊肉中p H值維持在5.58~5.83。
[Abstract]:[objective] to study the meat quality characteristics and influencing factors of Kirgiz sheep, so as to protect the germplasm resources of Kirgiz sheep. To provide a scientific theoretical basis for the rational development of Kirgiz sheep and tissue production. [methods] taking Xinjiang Kirgiz Sheep as the research object, we studied the same conditions of captivity. The contents of routine nutrients, physicochemical indexes, mineral elements and amino acids in skeletal muscle of Kirgiz sheep at 7 and 20 months of age. [results] crude fat in skeletal muscle of Xinjiang Kirgiz sheep was affected by different ages. Crude ash, crude protein, tenderness of mutton, iron, zinc, calcium, magnesium, copper, amino acid composition and total amino acid contents had significant effects on P0.01. [conclusion] Kirgiz sheep's skeletal muscle protein, fat, inorganic matter, zinc, calcium, magnesium, copper and other mineral elements, amino acid species and the number of the richer, but the tenderness decreased, after slaughter for 2 hours, the pH value of mutton maintained at 5.58 ~ 5.83.
