                                  要降低母猪分娩时仔猪的死产率就必须预防母猪产程延长并尽量缩短产仔时间生产中加强饲养管理预防为主
                                 

                                     1控制好母猪分娩时的体况防止过肥或过瘦?#23548;?#24037;作中母猪分娩时的体况应背部丰满有一条平的上线不见任何骨头突出在腰椎以下肋骨后面和骨盆前面应有一个陷窝过肥母猪无陷窝所以妊娠母猪在100天以前应根据胎儿生长发育规律和母猪膘情肥瘦做好限制饲养工作又能防止母猪过肥
                                 

                                     2母猪产前一定要限料饲喂为了减轻胃肠负担过重对产仔的不利影响母猪产前3天以预产期为准要开始限料限料标准为产前第3天每头每天3千克产前第2天每头每天2千克产前第1天每头每天1千克母猪分娩?#20445;?#20135;仔当餐不喂料隔半天再喂料0.5千克比如母猪早上产仔早上母猪停喂下午喂料0.5千克下午产仔下午停喂产后第1天早上喂料0.5千克下午也喂料0.5千克产后第2天每头每天2千克产后第3天每头每天3千克产后4天——断奶自由采?#22330;?#21363;产前限料从多到少产后加料从少到多以防止母猪产后消化不良
                                 

                                     3防止母猪产前便秘建议在母猪分娩前后1周在饲料中拌入1%的硫酸钠和0.5%的大黄苏打粉可使母猪粪便松软湿润有利于排便畅通有条件的猪场如能使用泌乳进更好
                                 

                                     4夏天要加强怀孕母猪的防暑降温工作特别是怀孕后期的母猪和上产床的临产母猪怀孕母猪实行限位饲养密度大散热困难尤其是怀孕后期母猪采食多食后体热增加体温比采食前上升0.5左右达到39.5棬当妊娠102-110天的母猪体温长期维持该温度?#20445;?#20998;娩时仔猪死产率升高?#23454;?#29615;境温度达到30以上?#20445;?#24314;议间隔半小时对配种舍怀孕母猪实行喷雾降温对产房的临产母猪冲水降温尽量减少热应激对母猪的影响
                                 

                                     5对于正产仔的分娩舍应尽可能保持舍内安静特别对初产母猪尤其重要当母猪烦躁不安?#20445;?#25353;摩乳房可使其安静下来?#28304;?#36827;顺利分娩很有意义
                                 

                                     6仔猪生后擦干粘液烘干被毛后要立即放到母猪乳房?#21592;?#21507;奶通过仔猪不断吮吸乳头可刺激母猪下丘脑分泌催产素引起子宫收缩不仅有助于顺利分娩缩短产程也有利于乳汁排出
                                 

                                     7做好疫苗接种工作预防母猪繁殖障碍性疾病对?#30142;?#29482;只特别是发烧母猪及时治疗选自新牧网
