不同卧床材料对海福特母牛舒适度、繁殖及健康状况的影响

目的] 为了研究不同卧床材料对海福特母牛舒适度、繁殖及健康状况的影响。方法] 将600头海福特母牛随机分为 4 组,每组150头,分别散放饲养于混凝土地面、砖铺地面、木屑垫料、细沙子卧床,测定微生物数量,观察母牛舒适度、受胎率、健康状况；结果] 结果表明,细沙子和砖铺地面的霉菌显著低于混凝土地面和木屑垫料(P<0.05)；细沙子中的金黄色葡萄球菌数量极显著低于混凝土地面和木屑垫料(P<0.01)；细沙子中的大肠杆菌数量最少,显著低于混凝土地面、砖铺地面和木屑垫料(P<0.05)。细沙子和木屑垫料能显著提高海福特母牛躺卧率(86%和90%,P<0.05),显著高于混凝土地面和砖铺地面；使用细沙子和木屑垫料比混凝土地面和砖铺地面显著降低了海福特牛肢蹄病发病率(14%和5%,P<0.05)。细沙子垫料与混凝土地面、砖铺地面、木屑垫料相比较,显著提高了海福特母牛受胎率和犊牛成活率(92%、98%,P<0.05)。结论]细沙子垫料与混凝土地面、砖铺地面、木屑垫料相比较,显著降低了霉菌、金黄色葡萄菌和大肠杆菌的数量,提高了海福特母牛躺卧率、受胎率和犊牛成活率,降低了肢蹄病发病率。

Effects of different bedridden materials on comfort, reproduction and health of heifer

Objective ] To study the effects of different bedridden on comfort, reproduction and health of beef cattle.Methods ]600 heifers were randomly divided into 4 groups (150 cows in each group) , which were randomly reared on concrete floor, brick floor, sawdust bedding and fine sand bed respectively, the results showed that the mold content of sand and brick floor was significantly lower than that of concrete floor and sawdust bedding (P<0.05) .The amount of Staphylococcus aureus in fine sand was significantly lower than that in concrete floor and sawdust bedding (p<0.01) , it was significantly lower than that of concrete floor, brick floor and sawdust bedding (p<0.05) . Fine sand and sawdust bedding significantly increased the lying rate of heifer (86% and 90% , P<0.05) , significantly higher than that of concrete floor and brick floor Using fine sand and sawdust bedding significantly reduced the incidence of foot and limb disease in heifer cows (14% and 5% , p<0.05) . Compared with concrete floor, brick floor and sawdust bedding, fine sand bedding significantly increased the conception rate and calf survival rate of heifer (92%, 98% , p<0.05) . Conclusion ] Compared with concrete floor, brick floor and sawdust bedding, fine sand bedding significantly increased the lying rate, conception rate and calf survival rate of heifer heifer, and decreased the incidence of limb and hoof disease of heifer.
