Ruminants are readily able to digest phytate because of the phytase produced by rumen microorganisms. This is also where the ruminant digests the microbes produced in the rumen. Ruminant animals are those that have a rumen. The rumen of the water buffalo has important differences from that of other ruminants. The cud is then swallowed again and further digested by specialized microorganisms in the rumen. Improved fermentability of soya meal nitrogen in the rumen may occur. For optimal digestion, the environment of the rumen must be ideal for the microbes. Most dietary carbohydrates are fermented into VFAs in the rumen. Although protozoa are not essential for rumen functioning, their presence has pronounced effects. No enzymes are secreted in the rumen. They are produced, by fermentation, in the rumen of these animals. Lipids are otherwise inert in the rumen. The reticulum is adjacent to the diaphragm, lungs, abomasum, rumen and liver. The first two chambers are the rumen and the reticulum. The productivity of dairy cattle is most efficient when the cattle have a full rumen.
