动物科学
生殖生物学
奶牛群管理

背景情况:

乳牛的早期产后性质 (EPEC) 对乳牛的生育非常重要.
自动监测设备 (AMD) 可以跟踪EPEC并提供对生殖潜力的洞察力.
预测生育率有助于优化群体的繁殖性能和经济效率.

研究的目的:

研究EPEC与奶牛生殖结果之间的关联.
根据EPEC开发和测试用于预测生育潜力的算法.
根据生育水平分类的牛的生殖表现进行比较.

主要方法:

使用了来自3个商业奶牛群的4,578头牛的数据.
收集了关于分娩,产后健康,奶产,EPEC和环境因素的数据.
使用后勤回归和Cox比例危险回归进行统计分析和算法开发.

主要成果:

在牛奶中至少发生一次雌激发事件 (DIM) 的奶牛在第一次服务和更高的高生育率 (HFERT) 分类中显示出更高的怀孕率.
较低的反最低值与怀孕的几率增加和怀孕的风险增加250 DIM.
将奶牛分为生育群体显示出开放日和怀孕率的显著差异.

结论:

乳牛产后的早期性质 (EPEC) 是乳牛生殖潜力的重要指标.
将EPEC与健康,遗传和环境数据相结合,可以提高生育预测的准确性.
使用EPEC的算法可以预测乳牛的长期生殖性能,从而优化群体管理.

Cloning of Dolly the Sheep

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...
