摘　　要：妊娠限位栏虽能提高饲养密度并降低管理成本,但也带来诸多福利问题。设计了全垫草小群妊娠圈,研究妊娠环境对母猪行为及生理性状的影响,了解该稻草圈对母猪福利的影响。研究结果表明,稻草丰富群养妊娠圈与限位栏相比,能满足妊娠母猪的行为需求、激发稻草相关行为、满足采食动机、减少饮水行为及啃栏、无食咀嚼等规癖行为的发生,降低皮质醇水平,减少应激。稻草圈仍存在无食咀嚼和啃栏行为,表明为高产次母猪改善妊娠环境并不能完全消除早期环境的影响。Although the gestation crate increased the stocking density and reduced management costs, it brought many animal welfare issues. A straw bedded gestation pen for small group was designed to study the effect of environment on behavior and physiology of sows. The results showed, compared to the crate, the straw enriched pen met the behavior needs of gestating sows, stimulated straw-related behavior, and reduced the feeding motivation, the drinking behavior and stereotypies such as vacuum chewing and bar-biting. It also lowered the cortisol concentration, and reduced stress. But there were also few vacuum chewing and bar-biting in straw pen,which meaned that improved pregnancy environment couldn＇t completely eliminate the influence of early environment on older parity sows.
