摘要
养殖场后备母猪群不仅对后代仔猪有较大的遗传影响,还会对后代仔猪的正常生长发育产生影响,同时也会影响养殖场的整体养殖效益和成本投入。随生猪养殖规模不断扩大,集约化规模化养殖场后备母猪的引种频率不断增加,但在新品种引进中,如果没有落实严格的引种制度,易引入新的疫病,使生猪生长面临较大危险。需要落实严格的后备母猪引种制度,明确最佳的引种方法,并做好后备母猪的饲养管理工作,保证后备母猪健康生长,快速达到繁殖阶段,发挥后备母猪的繁殖能力。该文主要论述后备母猪的引种程序及饲养管理措施。
The reserve sows not only have a great genetic influence on the offspring piglets,but also have an influence on the normal growth and development of the offspring piglets.With the continuous expansion of the scale of pig breeding,the frequency of introducing gilts to intensive scale farms has been increasing.However,in the introduction of new breeds,if no strict introduction system is implemented,new epidemic diseases will be easily introduced,put the growth of live pigs in greater danger.It is necessary to carry out the strict breeding system of gilts,make clear the best breeding method,and do a good job in raising and management of gilts,so as to ensure the healthy growth of gilts,reach the breeding stage quickly and bring into full play the breeding ability of gilts.The introduction procedure and feeding and management measures of gilts were discussed in this paper.
