A limited amount of research is available related to the rumen microbiota of calves, yet there has been a recent spike of interest in determining the diversity and development of calf rumen microbial populations. To study the microbial populations of a calf's rumen, a sample of the rumen fluid is needed. One way to take a rumen fluid sample from a calf is by fistulating the animal. This method requires surgery and can be very stressful on a young animal that is trying to adapt to a new environment and has a depressed immune system. Another method that can be used instead of fistulation surgery is a rumen pump. This method requires a tube to be inserted into the rumen through the calf's esophagus. Once inside the rumen, fluid can be pumped out and collected in a few minutes. This method is quick, inexpensive, and does not cause significant stress on the animal. This technical note presents the materials and methodology used to convert a drenching system into a rumen pump and its respective utilization in 2 experiments using dairy bull calves.

技术说明:犊牛的简单瘤胃采集设备:手动瘤胃淋淋系统的改编

与小牛的瘤胃微生物群有关的研究有限,但最近在确定小牛瘤胃微生物种群的多样性和发展方面引起了人们的兴趣。为了研究小牛瘤胃的微生物种群,需要瘤胃液样本。从小牛采集瘤胃液样品的一种方法是通过瘘管动物。这种方法需要手术,并且会对试图适应新环境且免疫系统低下的幼小动物造成很大压力。可以代替瘘管手术的另一种方法是瘤胃泵。这种方法需要通过小牛的食道将一根管子插入瘤胃。一旦进入瘤胃,就可以在几分钟内将液体泵出并收集。这种方法快速,廉价,并且不会对动物造成明显的压力。本技术说明介绍了用于将淋水系统转换为瘤胃泵的材料和方法,以及在两个使用牛犊牛的实验中的用途。
