概括

奶牛重组可能会引起社会压力,影响行为和牛奶脂肪. 初配牛表现出更多的负面影响,而多配牛更好地适应社会环境的变化.

科学领域:

动物科学动物科学
乳制品畜牧业乳制品畜牧业
动物福利动物福利

背景情况:

住房系统中的奶牛经常被重新组合起来进行管理.
重组可以引起社会压力,影响行为,表现和福利.
了解这些影响对于优化奶牛群管理至关重要.

研究的目的:

研究重组对奶牛行为,皮质醇,催产素,牛奶产量和质量的影响.
根据平价区分影响 (原生母牛与多生母牛).
为了评估机器人挤奶系统对福利的影响.

主要方法:

观察52只哺乳母牛的行为 (社交互动,独处,养) 在四个时间区块内围绕重组.
从机器人挤奶系统收集的牛奶产量,活动,反 (RUM) 和牛奶成分数据.
使用线性混合效应建模分析了牛奶皮质醇和催产素度.

主要成果:

在重新分组后,初生母牛的社交互动减少;两组在重新分组当天的食时间都减少了.
在重新分组后,乳脂在两个平价群体中都显著下降.
每日活动增加,反时间减少,催产素水平在重组后下降;皮质醇和牛奶DM不受影响.
在重新分组后,原生母牛的奶产降低了,与多生母牛不同.

结论:

重组对原生母牛的社会行为和牛奶产量产生负面影响,这表明短期的社会不稳定.
多夫妇牛似乎更有弹性,可能从以前的重组经验中受益.
日常活动,反和催产素的变化表明生理应激对重组的反应.

Naturalistic Observations

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
