What is the relationship between the characteristics of the cow's rumen and feeding and management?

The digestive characteristic of the cow's rumen is that it has a large capacity for storing, processing and fermenting food. This makes the rumen a huge, highly automated "feed fermentation tank" within the cow's body. According to this characteristic, in actual cattle feeding, the first thing is to meet the need for a large amount of feed intake, providing a filling amount of feed; the composition of the feed should be based on roughage, with an appropriate proportion of concentrates, achieving strong palatability, diversity and relative stability, so that the various microorganisms in the rumen develop in balance and energy conversion remains at a highly efficient level.
