【摘要】：试验旨在研究沙子-混凝土(SC)地面对蛋鸡趾部的磨短程度以及群体等级是否影响蛋鸡的磨爪效果。将48只17周龄的京粉蛋鸡随机分为试验组与对照组2个处理,每个处理4个重复,每个重复6只。试验组为蛋鸡提供养殖笼及SC地面,对照组只为蛋鸡提供养殖笼。试验持续12周,每周对蛋鸡趾部长度与锐度进行数据采集。结果显示:(1)试验组与对照组蛋鸡趾长度在试验第二周就呈现显著性差异(P0.05),28周龄时试验组蛋鸡趾部长度为11.12 mm,对照组为13.87 mm。(2)试验组蛋鸡趾锐度显著低于对照组(P0.05),28周龄时试验组蛋鸡趾尖端曲率半径为1.26 mm,对照组为0.50 mm。(3)试验组不同等级蛋鸡在试验8周后均能实现有效磨爪。试验表明:SC地面可显著改善蛋鸡趾部长度及锐度,适合用于蛋鸡磨爪。
[Abstract]:The purpose of the experiment was to study the wear short degree of sand concrete (SC) ground facing the toes of laying hens and whether the population grade affected the clawing effect of laying hens. Forty-eight 17-week-old Jingfen laying hens were randomly divided into two groups: the experimental group and the control group, each treated with 4 replicates and each with 6 replicates. The test group provided cage and SC ground for laying hens, while the control group only provided breeding cages for laying hens. The experiment lasted 12 weeks. The length and acuity of toe were collected every week. The results showed that: (1) there was significant difference in toe length between the test group and the control group at the second week of the experiment (P0.05) the length of the toe of the test group was 11.12 mm at the age of 28 weeks, and that of the control group was 13.87 mm. (2) the toe acuity of the test group was significantly lower than that of the control group (P0.05) for 28 weeks. The radius of curvature of toe tip was 1.26 mm in the test group and 0.50 mm in the control group. (3) all the layers of different grades in the test group could effectively grind their claws after 8 weeks. The results showed that the toe length and acuity of the layers could be improved significantly by the weight SC ground, and it was suitable for laying hens to grind their claws.
