NOVELTY - Cellulase and protease enzyme complex cud liquor from cattle and buffalos cud for biodegradation of organic material, are prepared by collecting fodder loops inserted in the mouth of the cattle/buffalos; and dipping the loops embedded with the cud in at least1 L buffer nutrient solution to obtain cellulase and protease concentrate.    USE - The inventive process is for preparing cellulase and protease enzyme complex cud liquor (claimed) from cattle and buffalos cud for biodegradation of organic material. The cud liquor can be used as rumen modifiers, and as a growth promoter in the swine ration. It can be used as flavoring media for enhancing feed intake of animal feed in mash form, pellet form or compact feed block.    ADVANTAGE - The inventive process economizes the cost of testing biodegradation of organic materials. It does not need to maintain modified rumen fistulated cattle and buffalos, which is very costly affair and causes environmental pollution by emission of methane and other green house gases. In the cud liquor preparation of the inventive process, very minutely minced animal feed particles are present which are evenly distributed while coarse animal feed particle are present in conventional process (rumen liquor). The cud cellulase and protease complex can be used in bioremediation process. The cud liquor can be used as rumen modifiers that optimize rumen function especially under acidosis and anorexia conditions. Pharmaceutical industry can make use of the liquor. Capsule after lyophilization and ultrafiltration can be prepared for treating anorexia suffering cattle/buffalos. The invention provides a valuable solution to protect the cattle and the buffalos from the cruel act of rumen fistulation. It provides a substitute of imported growth promoter. The cud liquor can work as flavoring media for enhancing feed intake of animal feed in mash form, pellet form or compact feed block. This is a good substituted of imported costly flavoring agent.    DETAILED DESCRIPTION - Preparation of cellulase and protease enzyme complex cud liquor from cattle and buffalos cud for biodegradation of organic material, includes feeding the cattle/buffalos with green leguminous/non-leguminous fodder ad libitum; withdrawing the feed from the cattle/buffalos after 2-3 hours and wait till the cattle/buffalos are ruminating; inserting a fodder loop in the mouth of the cattle/buffalos; allowing the loop to stay in the mouth till the cud is embedded on the loop; repeating the inserting and allowing steps with separate fodder loops and different cattle/buffalos; collecting the loops from the mouth of the cattle/buffalos; and dipping the loops embedded with the cud in at least1 L buffer nutrient solution to obtain cellulase and protease concentrate.
