【摘要】：国内外目前对绒山羊的舍饲养殖技术研究不多,至于对密集繁殖“两年三胎”体系的饲养管理技术方案更是鲜见报道。本饲养管理技术方案,面对的主要对象是羊场技术人员的养殖技术人员。方案的制定的意义在于提高养殖科技含量,增加农民收入的需要,也是规范行业操作流程的必备。本论文的技术路线是从四方面进行。第一,从实地调研着手,调研的具体的内容包括了2015-2016年在陕西、山西所辖的24个县(区)的羊产业发展的现状,并对养殖方式、养殖规模、饲料种类、羊群结构组成和经济效益分析等情况做出了详尽的分析。第二,在陕北狄青塬种羊场进行了立地试验,试验用100%、110%和120%营养水平的日粮对母羊妊娠后期、泌乳期进行营养调控,得出了陕北白绒山羊“两年三胎”的实际生产数据。第三,方案的起草立足于陕北当地的生产需要,根据实地情况提出了不同的营养和饲料方案,结合实地的调研报告和试验应用的结果,结合本人羊场实践操作经验,同时参考了的大量的相关文献,并对内容进行了整合提炼。第四,由本人实验室课题组内老师,对方案的完整性、科学性做以讨论、评估和分析,并将方案交予驻场养殖技术人员,对方案的实际可操作性,和方案的实际指导作用做出及时反馈。“两年三胎”的饲养管理技术方案的制定,坚持的五个原则,分别是,坚持优选优配的原则、坚持周期性生产原则、坚持分群饲养管理原则、坚持目标管理原则和坚持程序化疫病防控原则。依托饲养管理技术手段形成的“两年三胎”为目的的密集繁殖体系,具体措施有公母羊的选择、羊群的选种选配、各个繁殖时间节点的母羊和羔羊营养饲料方案、生产周期控制和规范化疫病防疫流程等措施。方案的制定的过程以实地调研为基础,立地试验为生产实践依托,而后进行了方案的起草和征求意见。方案的内容从饲养管理的技术方案,到饲养管理技术措施,再到后期试验的应用等方面。对实际的问题,有针对性的表述了具体的操作方法。
[Abstract]:At present, there are few studies on the house-feeding and breeding techniques of cashmere goats at home and abroad, and few reports have been made on the feeding and management schemes of intensive breeding "two years and three births" system.The main object of the project is the technical personnel of sheep farm.The significance of the scheme is to improve the scientific and technological content of aquaculture, to increase farmers' income, and to standardize the operation process of the industry.The technical route of this paper is carried out from four aspects.First, starting from field research, the specific contents of the investigation include the current situation of sheep industry development in 24 counties (districts) under the jurisdiction of Shaanxi and Shanxi in 2015-2016, and the breeding methods, scale, and feed types.The composition of sheep structure and economic benefits are analyzed in detail.Secondly, the site experiment was carried out at Di Qing's Sheep Farm in Northern Shaanxi Province. The results showed that 100% and 120% diets were used to regulate the nutrition of ewe in late pregnancy and lactation period, and the actual production data of "two years and three births" of Northern Shaanxi White Cashmere Goat were obtained.Third, the drafting of the plan is based on the local production needs in northern Shaanxi. According to the situation in the field, different nutrition and feed schemes are put forward. Combined with the field investigation report and the results of the experiment and application, combined with the practical operation experience of my sheep farm,At the same time, reference to a large number of relevant literature, and the content of integrated extraction.Fourthly, the teachers of our lab group will discuss, evaluate and analyze the integrity and scientificalness of the scheme, and hand it over to the technicians in the field, so that it can be operated practically.And the practical guidance of the program to provide timely feedback.In the formulation of the technical scheme of feeding and management of "two years and three births", five principles are adhered to, namely, the principle of excellent selection and distribution, the principle of periodic production, and the principle of raising and management in different groups.Adhere to the principle of objective management and procedural disease prevention and control principle.The intensive breeding system for the purpose of "two years and three births", which is formed by the technical means of raising and management, has specific measures such as the selection of male and female sheep, the selection of sheep species, the feeding scheme of ewe and lamb at each breeding time node,Production cycle control and standardization of epidemic prevention procedures and other measures.The process of making the plan is based on field investigation, site test is based on production practice, and then the project is drafted and consulted.The content of the scheme is from the technical scheme of feeding management to the technical measure of feeding management, to the application of later experiment, etc.To the actual problem, has stated the concrete operation method pertinently.
