摘 要:奶牛集约化规模化养殖模式呈现不断加快发展的态势,但中小规模养殖模式依然占据主导地位。相对于集约化规模化养殖场,养殖小区农户散养养殖模式更加灵活,但是整体的养殖水平相对较低,某些饲养管理环节一旦不到位会影响产业发展,不利于提高养殖户的经济效益。需要结合散养奶牛养殖户养殖中存在的问题,加快科学饲养管理技术管理方法的推广应用,帮助广大散养养殖户更好地革新养殖技术,以提高奶牛养殖水平和养殖效益。该文主要论述散养奶牛养殖中存在的问题,并提出提高散养奶牛养殖效益的技术措施。The intensive scale breeding mode of dairy cattle has been developing rapidly,but the medium and small scale breeding mode still occupies the leading position.Compared with intensive scale farms,the model of free-range farming in farming areas is more flexible,but the overall level of farming is relatively low,and if some aspects of feeding management are not put in place,it will affect the development of the industry,not Conducive to improving the economic benefits of farmers.It is necessary to speed up the application of scientific feeding and management techniques in combination with the problems existing in the breeding of freerange dairy cattle farmers,and help the free-range dairy farmers to better innovate their breeding techniques,in order to improve the level and benefit of dairy cattle breeding.This paper mainly discusses the problems existing in the breeding of free-range dairy cattle,and puts forward the technical measures to improve the breeding efficiency of free-range dairy cattle.
