The fact that the stomach of the cow is a complex multi-level mechanism to digest the huge amount of fiber. At its core, is a mini-factory, in which due to the special microflora in the nutrients processed even cellulose. Therefore, the cow can safely eat, for example, hay.However, the microflora of the digestive tract of a cow is happy sensitive, and can easily disrupt an unbalanced diet. For example, when the cow after a long period of feeding hay abruptly switches to the power of young clover, beets or silage, then her problems begin. Microorganisms do not have time to readjust to digesting a new food, and the cow is suffering from a surplus in the rumen (the stomach). If time does not help the animal, he or she may even die from suffocation.
