METHOD FOR TREATING AND RECYCLING WASTE BLOOD AND RESIDUAL MATERIAL OF DIGESTIVE ORGAN OF SLAUGHTERED CATTLE AND PIG INTO FEED

摘要

PURPOSE:To produce a feed having a high aroma and excellent palatability of domestic animals, by mixing waste blood and undigested digestive organs of slaughtered cattle or pig with fowl droppings and an alcoholic waste liquor, and carrying out the fermentation. CONSTITUTION:Waste blood and residual undigested digestive organs of slaughtered cattle or pig are mixed with fowl droppings and an alcoholic waste liquor or molasses and a fermentation assistant, and the warm or hot water is added preferably to the materials in mixing to increase the total temperature rapidly to 30-50 deg.C. The above-mentioned mixture is then divided into fine particles and dispersed in a mixer, and fine air bubbles are dispersed and mixed all over the mixture. Thus, the composite lactic acid fermentation ranging from the aerobic to anaerobic fermentation is carried out in the above-mentioned mixture.
