| 摘 要： | 本试验利用母猪行为以及唾液皮质醇和淀粉酶含量探索空间限制对母猪生理心理状态造成的影响。试验选择大白妊娠母猪64头,随机平均分成2组,分别采用限位栏(180 cm×60 cm×110 cm)和群养模式(568 cm×448 cm×50 cm)饲养,群养模式下每圈8头母猪,共4圈。于试验1、3、5、6、8、10、11、13、15周第1、2天分别采用10 min间隔扫描取样法记录母猪行为和采集试验母猪唾液样本,检测唾液皮质醇水平和唾液淀粉酶含量。结果表明:限位栏母猪表现无食咀嚼、啃栏、啃槽行为的次数显著高于群养母猪。限位栏母猪的唾液皮质醇和淀粉酶表现出相反的分泌趋势,无食咀嚼与唾液淀粉酶含量之间存在显著的正相关关系(r=0.336,P=0.048)。群养模式下试验母猪的唾液皮质醇水平、淀粉酶含量与无食咀嚼行为之间没有显著性相关的关系。

Effect of Confinement on Sows Behavior,Salivary Cortisol Level and Salivary Amylase Concentration |

| Abstract: | The aim of this study was to examine the effect of confinement on sows physiological and psychological state by animal behavior,salivary cortisol level and salivary amylase concentration.A total of 64 pregnant Long White sows were equally divided into two groups randomly.The sows from two groups were housed in standard individual stalls(180 cm×60 cm×110 cm) or group-housing system of 8 sows per group(568 cm ×448 cm ×50 cm).10-min interval scan sampling was used to record sows behavior,salivary cortisol and amylase were repeatedly measured on first and second day in weeks 1st,3rd,5th,6th,8th,10th,11th,13th,15th of the experiment,respectively.Sows in stalls showed a significantly lower frequency of sham chewing,bar manipulation and trough manipulation.There exist some significant changes in salivary cortisol level and salivary amylase concentration with time in stalls and these changes are significant different.Significant positive correlations were found between salivary amylase and sham chewing behavior(r =0.336 P =0.048) in stalls.No significant correlations were foundamong salivary cortisol level,salivary amylase concentration and sham chewing behavior in house. |
