| 摘要: |
| 研究舍饲圈栏条件下猪对环境丰富度材料的选择倾向性。随机抽取20头70~150日龄生长育肥猪,选择不同的啃咬、鼻拱及蹭痒材料,就生长育肥猪对各种材料的接触频次及时间等行为学指标进行研究。结果表明:生长育肥猪对各种材料的选择偏爱程度随放置时间的延续而减弱;对啃咬材料的接触频次大小和接触时间长短顺序依次为,铁链>尼龙绳>剪成条状的自行车内胎>塑料水管>细铁棍,其中对铁链的接触频次显著高于其他材料;对鼻拱材料的接触频次大小、接触时间长短依次为新鲜泥土>鹅卵石>蘑菇培养土>稻草>碎木屑>玩具塑料球;猪蹭痒时更多的选择木质蹭痒架。 |

| Study on selection preference of finishing pigs for environmental enrichment materials |

| Abstract: |
| It is an important technical measure to improve the welfare of housing pigs by increasing the environmental enrichment.To investigate the selection preference of finishing pigs for different environmental enrichment materials in a housing system,some environmental enrichment materials were tested in this study.The actions of 20 finishing pigs randomly selected were video-recorded and analyzed the contact frequency and time.The result showed that the contact frequency and times between the pigs and the gnawing materials decreased with the time of a material to be provided.The sequence of the contact frequency and time was: iron chain>nylon string>striped bicycle inner tube>plastic water pipe>thin iron stick.The average contact frequency of iron chain is significantly higher than that of others.The sequence of contact frequency and time between pigs and the rooting materials is: fresh clay>cobble>incubation earth for mushroom>straw>smashed sawdust>plastic ball.The favorite ranking material for pigs is wood shelf. |
