【摘要】 不良的畜床环境是导致母猪肢蹄损伤发病率高的关键因素。为探明不同畜床环境对猪肢蹄损伤发病率影响的差异 ,对采用不同畜床饲养的母猪进行了观察和对比试验。发现冷、硬、潮混凝土畜床上的母猪肢蹄损伤发病率高达 3 7.7% ,全漏缝地板畜床发病率为 3 0 .5 % ,局部漏缝地板发病率则在 2 5 %。简易节能型畜床肢蹄损伤发病率仅为 5 .18% ,使猪肢蹄损伤发病率下降了 70 %～ 80 % ,这一结果证明 ,通过改变畜床材料和结构来改善畜床环境的新思路、新方法是可行的。更多还原

【Abstract】 Poor environmental conditions in stall floors was the key factor affecting the health of feet and limbs of sows. Incidence rate of foot and limb injuries among sows raised for a long time in various types of stall was investigated .The results show that the incidence rate of foot and limb injuries among sows raised on cold and hard cement ground, discretely arranged cement floor board, partly discretely arranged cement floor board and simple energy saving floor was 37.7%, 30.5%, 25%, 5.81%, respectively. The best stall floor is a simple energy saving floor with improved material and structure of floor board .The incidence rate of foot and limb injuries among sows raised on them decreased by 70%~80%. The results suggest that a good way to improve environmental conditions is by changing the material and structure of floor boards.更多还原
