| 摘 要： | 研究笼养密度分别为17只/m2(高密度)、14只/m2(中密度)和11只/m2(低密度)条件下,4~6周龄肉仔鸡的行为特点,以及笼养密度与胸囊肿发生率的关系。结果表明:笼养肉仔鸡各行为持续时间比例中趴卧最高,达77.08%。6周龄肉仔鸡行为与4和5周龄的相比,其行为受密度的影响最大:高密度下趴卧持续时间长、频次低(P<0.05);低密度下行走、饮水、采食、梳羽、舒展、晃动等活动型的行为频次高、持续时间长(P<0.05);高密度下胸囊肿发病率显著高于低密度(P<0.05),且发病率与晃动、梳羽行为持续时间比例及趴卧频次均具有显著的负相关关系(r=-0.997,P=0.048;r=-0.999,P=0.028;r=-0.996,P=0.034)。高笼养密度条件下,肉仔鸡趴卧行为持续时间长,晃动、梳羽等活动型行为持续时间缩短,频次降低,其胸囊肿发生率增大。

| Abstract: | In order to investigate influencing theory of stocking density on the incidence of breast blister for broilers,the behavior patterns of broilers caged in different densities,17 birds/m2,14 birds/m2 and 11 birds/m2 from the ages of four weeks to six weeks were observed.The results showed that broilers performed more sitting on the cage floor(arrived at 77.08%).The stocking density had the greatest effect on the behavior of broilers in 6 weeks compared with 4 and 5weeks.The duration and number of sitting were more in high density(17 birds/m2) than in low density(11 birds/m2)(P<0.05),while the duration and number of active behaviors,such as walking,drinking,feeding,preening,stretching and shaking in low density,were more than high density(P<0.05).Meanwhile the incidence of breast blister was significantly higher in high density than in low density(P<0.05).There was significantly negative correlation between the incidence of breast blister and the duration of shaking,preening and the number of sitting(r=-0.997,P=0.048;r=-0.999,P=0.028;r=-0.996,P=0.034).This present study showed that the duration or number of sitting,shaking and preening were much effected by stocking density,so as to the incidence of breast blister was done. |
