木板与混凝土牛床对奶牛肢蹄的影响研究

The Effect of the Feet and Legs Disorders of Cow Under Wood or Concrete Ground Conditions

本研究比较了木板地面和混凝土地面的牛床对奶牛肢蹄损伤性疾病的发病情况,结果显示:木板地面和混凝土地面牛床的发病率分别为53.18%,66.99%,木板地面的发病率显著低于混凝土地面(P<0.05),且在低气温季节,混凝土地面发病率极显著高于木板地面(P<0.01),而在高气温季节则相反(P<0.05)。腕(跗)部发病率,木板地面低于混凝土地面(P<0.05),分别为22.22%,34.06%。细菌感染率木板地面高于混凝土地面,差异显著(P<0.05)。指(趾)部和蹄部发病率、患病淘汰率,木板均高于混凝土地面,但差异不显著(P>0.05)。结果说明,不同气温(季节)条件下,木板与混凝土地面对奶牛肢蹄损伤差异较大,但总的来说,木板地面要优于混凝土地面。

The feed and legs disorders in dairy cow under wood floor and concrete ground conditions were compared. The results showed that the in cidence of the discase were 53.18% and 66.99% respectioly which was significantly lower under wood floor and condition (P<0.05). With the low temperature, the incidence of disease in concrete ground stall was higher remarkablly, and opposite during high temperature season. The incidence of carpus disease in wood floor and concrete ground stall were 22.22%, 34.06% iespectively, significantly different (P<0.05). The eliminated percentage and incidence of foot and limb injuries in wood floor stall were higher than that under concrete ground condition, but the difference was not significant. This study showed that the difference of foot and limb injuries in dairy cows under wood floor and concrete ground condition were obvious in different seasons, but wood floor was superior to concrete ground in the long run.
