Rumen digesta causes water pollution by entering into the rivers, streams, and local water sources. Rumen digesta also causes environmental pollution by its conversion into methane and carbon dioxide. We can save our environment from rumen digesta pollution by recycling of rumen digesta. One of the best methods to recycle rumen digesta is making silage with crop residue because rumen digesta is good source of beneficial micro-organism and as well as good source of partially digested feed material of high nutritive value. We know, in developing countries agro-industrial wastes contribute huge feed resource for ruminants. These feed resources are high in poorly digestible fiber, low in carbohydrate and protein. Ensiling of rumen digesta with agro-industrial by products not only helps to improve the nutritional value agro-industrial by products like improving protein contents and reducing pH, fiber contents and lignin. Furthermore, the ensilation of rumen digesta with agro-industrial by products increases their digestibility. So, by ensilation of rumen with crop residue we can save our environment and at same time we can fulfill the nutritional requirement of the ruminants in developi
