概括
使用不同范围的环境丰富并没有显著改变赤裸的行为或蛋质量. 较大范围的地区对生产绩效产生了积极影响,但对福利指标没有影响.
科学领域:
- 动物科学动物科学
- 禽畜科学 禽畜科学 禽畜科学
- 动物福利 动物福利
背景情况:
- 环境丰富对于家禽的福利和生产力至关重要.
- 裸子是一种独特的品种,具有自由放牧系统的潜力.
- 了解范围面积大小对表现和福利的影响至关重要.
研究的目的:
- 评估不同范围区域大小对赤裸子行为的影响.
- 评估范围区域对福利指标的影响.
- 为了确定对生产绩效和蛋质量特征的影响.
主要方法:
- 1080只裸的雌性被安置在三个不同的范围区域 (121.9米2,152.4米2,190.5米2).
- 行为观察,福利评估 (脚皮炎,),生产性表现 (蛋产量,料摄入量) 和蛋质量被测量.
- 采用了一个完全随机的设计,每次治疗有4次复制.
主要成果:
- 范围区域大小没有影响大多数行为或蛋质量特征,除了步行和范围使用.
- 较大的范围面积 (190.5平方米) 提高了生产性能 (蛋重量,产量,质量,料摄入量).
- 福利特征没有受到不同范围区域的显著影响.
结论:
- 通过各种范围的环境丰富并没有显著改变裸的行为或蛋质量.
- 最佳的范围面积大小,结合有效的环境丰富,如息和尘埃浴,是后院家禽推的.
- 自由范围的系统可以支持良好的性能,但仔细考虑空间和丰富是关键.

01:20Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

00:54What is Behavior?
9.0K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.
