摘要
为培育我国自主知识产权的新品种奶绵羊,本研究对戴瑞羊(DM)、小尾寒羊(STH)、戴寒杂交F_(1)(F_(1))和戴寒杂交F_(2)(F_(2))乳中常规成分、脂肪酸、氨基酸、矿物质和维生素进行了比较分析。结果表明,F_(1)乳的脂肪含量最高,其蛋白质、酪蛋白、固形物和非乳脂固形物以及必需氨基酸含量仅次于STH乳,显著高于DM和F_(2)乳(P<0.05),而以上指标在DM与F_(2)乳之间无显著差异(P>0.05)。DM乳中亚油酸、花生四烯酸、MUFA、PUFA脂肪酸等功能性脂肪酸的相对含量均高于其它组。F_(1)乳中维生素B_(12)、叶酸以及短链脂肪酸、α-亚麻酸和ω-3脂肪酸含量高于其它组。本研究结果表明,新品种奶绵羊培育群体的乳中均含有丰富的营养物质,本研究为新品种奶绵羊的选育和本土化绵羊乳制品的开发提供了理论依据,可根据具体需求选择合适的乳生产群体。
This study aimed to cultivate intellectual property rights of dairy sheep breeds in China,the conventional components,fatty acids,amino acids,minerals and vitamins in the milk of Dairy sheep(DM),Small-Tailed Han sheep(STH),Dairy-Han crossbred first generation F_(1)(F_(1))and Dairy-Han crossbred F_(2)(F_(2))were compared and analyzed.The results showed that the fat content of F_(1) milk was the highest in four groups.Its protein,casein,solids and non-milk fat solids and essential amino acids content were lower than STH milk,but significantly higher than DM and F_(2) milk(P<0.05).Those indicators were no significant difference between DM and F_(2) milk(P>0.05).The relative contents of functional fatty acids such as linoleic acid,arachidonic acid,MUFA and PUFA fatty acids in DM milk were higher than the other.The vitamin B12,folic acid,short-chain fatty acids,α-linolenic acid and ω-3 fatty acids in F_(1) milk were higher than those in other groups.The results showed that the milk of new dairy sheep breeding group was rich in nutrients.This study provides a theoretical basis for the breeding of new breeds of dairy sheep and the development of localized ovine dairy products.Appropriate lactation groups could be selected based on the specific needs.
