摘要
[目的]探究鲁西斗鸡屠宰性能和鸡肉营养成分。[方法]测定鲁西斗鸡屠宰性能、营养成分、主要矿物质元素、氨基酸的含量。[结果]屠宰率、全净膛率、腿肌率分别达到93.26%、73.40%和24.71%。产肉性能良好,腿肌率较高。鲁西斗鸡营养成分中,蛋白质20.50%,检测出的16种游离氨基酸187.5 g/kg,其中必需氨基酸76.0 g/kg,5种鲜味氨基酸79.2 g/kg。不饱和脂肪酸2.32%,富含亚油酸、亚麻酸、花生四烯酸、DHA和二高-y-亚麻酸。矿物质中,硒含量54.0μg/kg,铁含量5.7 mg/kg,锌含量6.4 mg/kg。[结论]鲁西斗鸡鸡肉营养丰富,适合肉用开发,在一定程度上揭示了鲁西斗鸡风味突出的种质特性。
[Objective]To explore the slaughtering performance and nutritional composition of Luxi fighting chicken.[Method]The slaughtering performance,nutritional composition,main mineral elements and amino acid content of Luxi fighting chicken were determined.[Result]The slaughtering rate,full clean bore rate and leg muscle rate reached 93.26%,73.40%and 24.71%respectively.The meat production performance was good,and the leg muscle rate was high.Among the nutrients of Luxi fighting chicken,protein was 20.50%,and the detected 16 free amino acids were 187.5 g/kg,including 76.0 g/kg of essential amino acids and 79.2 g/kg of five delicious amino acids.Unsaturated fatty acids were 2.32%,rich in linoleic acid,linolenic acid,arachidonic acid,DHA and dihydro-y-linolenic acid.Among minerals,selenium content was 54.0μg/kg,iron content was 5.7 mg/kg,and zinc content was 6.4 mg/kg.[Conclusion]Cockfighting chicken was rich in nutrition and suitable for meat development,which reveals the germplasm characteristics of Luxi cockfighting chicken with outstanding flavor to a certain extent.
