At present, in order to alleviate the pressure of closing hillsides and forbidding grazing, and achieve a win-win situation of rural revitalization and ecological restoration, the breeding mode of white cashmere goats in Dingbian County has also begun to change from extensive breeding mode to standardized house feeding. However, some farmers in the county did not master the scientific method of house feeding. Based on this, the problems existing in the house feeding of Shanbei white cashmere goats were analyzed, and the specific breeding techniques were pointed out, so as to effectively improve the farmers breeding benefits, and provide more reference for the future work of Dingbian white cashmere goats breeding.展开更多
为了研究子午岭黑山羊和陕北白绒山羊粪便微生物结构和功能差异,试验采用16S r DNA扩增子高通量测序技术对2周岁的子午岭黑山羊和陕北白绒山羊母羊粪便微生物结构与组成进行研究并对其功能进行预测分析。结果表明:子午岭黑山羊和陕北白...为了研究子午岭黑山羊和陕北白绒山羊粪便微生物结构和功能差异,试验采用16S r DNA扩增子高通量测序技术对2周岁的子午岭黑山羊和陕北白绒山羊母羊粪便微生物结构与组成进行研究并对其功能进行预测分析。结果表明:子午岭黑山羊和陕北白绒山羊的优势菌门均为厚壁菌门、拟杆菌门和变形菌门,三者占整个菌群的91%以上,次级优势菌门为螺旋体门和疣微菌门;子午岭黑山羊和陕北白绒山羊的优势菌属为不动杆菌属、UCG_005、克里斯滕森菌科R-7群。子午岭黑山羊粪便中的弯曲杆菌门相对丰度显著高于陕北白绒山羊(P<0.05);陕北白绒山羊粪便中普雷沃氏菌属、马氏菌科未分类属相对丰度极显著高于子午岭黑山羊(P<0.01);毛螺菌属、螺旋菌属、双歧杆菌科未分类属、拟杆菌属显著高于子午岭黑山羊(P<0.05)。陕北白绒山羊粪便微生物的甘油磷脂代谢、酮己糖激酶、天冬氨酸脱氢酶等功能相对丰度显著高于子午岭黑山羊(P<0.05);子午岭黑山羊粪便微生物的假单胞菌素、二氢二醇脱氢酶、帕金森病蛋白7、硒蛋白相关蛋白、烷基过氧化物酶等功能相对丰度显著高于陕北白绒山羊(P<0.05)。说明子午岭黑山羊粪便微生物种类、数量和功能均与陕北白绒山羊有所差异,提示有必要研发专用饲料以提升饲喂效率。展开更多
