概括

一个新的基于牧场的乳制品系统,与牛小牛的长期接触和每天一次的挤奶显示,小牛的体重增加速度更快. 这种系统减少了可销售的牛奶产量,但增加了断奶前的牛奶蛋白.

科学领域:

乳制品科学乳制品科学
畜牧业动物养殖动物养殖
基于牧场的生产系统

背景情况:

传统的乳制品系统往往会早早地将奶牛和小牛分开,影响小牛的福利和生长.
在基于牧场的系统中,作为一种替代的管理策略,探索了延长牛犊接触.

研究的目的:

为了评估一个新的10周,基于牧场,延长哺乳系统的牛犊生产力.
为了将这个系统与澳大利亚的传统乳业管理实践进行比较.

主要方法:

三十只奶牛和小牛被分为两组:延长哺乳期与兼职接触和线分离,或常规分离.
扩大哺乳组的奶牛每天一次,而常规奶牛每天两次.

主要成果:

扩大哺乳母产量为9升/母牛/天,可销售的牛奶较少,脂肪含量较低,但在断奶前蛋白质含量较高.
母乳养的小牛体重增加得更快,使得它们比传统养的小牛早两周的断奶.
乳汁产量和成分在断奶后的两组之间变得可比.

结论:

调查的扩展牛犊哺乳系统是基于牧场的奶牛养殖场的潜在实用替代方案.
需要进一步的研究来验证这种新的乳制品管理方法的长期影响和可扩展性.

关键词:

牛和小牛之间的接触.联系大联系大养大的养殖牧场系统的牧场系统.季节性的生犊生育.

Development of Human Microbiota

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
