四种不同地板对妊娠母猪肢蹄健康的影响

Effects of Four Different Floor Types on Limb and Hoof Health of Pregnancy Sow

为探索饲养妊娠母猪适宜的地板类型,对河南省四家规模化猪场妊娠母猪(前4个胎次)肢蹄部健康状况进行调查研究。使用不同四种地板的母猪发病率和淘汰率分别为:新型复合材料漏缝地板病变发生率为12%、淘汰率5.92%;三合土地板病变发生率为15%、淘汰率12.9%,铸铁漏缝地板病变发生为20%、淘汰率9.75%;混凝土实体病变发生为26%、淘汰率15.7%。结果证明:使用新型复合材料漏缝地板的母猪肢蹄部健康状态最好;三合土地板次之;铸铁漏缝地板和全混凝土地板较差。新型复合材料地板能显著改善母猪肢蹄部健康,有效降低限位饲养母猪肢蹄病的发生率和淘汰率。

To finding the appropriate type of floors in pregnancy sows,there was an investigation that the healthy situation of limb and hoof health of 1 to 4 parity sow in four industrialized pig farms by using the different floors that were the new composite slatted floor, concrete composite floor,cast iron slatted floor and full concrete floor. The results showed that the limb and hoof lesions rate was 12%, 15%,20% and 26%,and the culled rate was 5.92%, 12.9%,9.75% and 15.7% respectively by using the new composite slatted floor,concrete composite floor,cast iron slatted floor and full concrete floor. The data showed that the use of new composite floor was the best to improve the limb and hoof health, followed by the concrete composite floor. Cast iron slatted floor and full concrete floor were worse. The new composite slatted floor could improve the healthy situation of the sows significantly, and reduce the lesions and culled rates greatly of sows.
