Abstract
Technology of Multi-stage Sterilization of Raw Materials with the Production of Feed Meal of High Biological Value
Highlights
Due to their biological usefulness, raw materials and feed of animal origin are a good nutrient medium for the development of various microorganisms
The quality assessment of feed meal from animal waste was carried out by standard methods: sampling and test methods of feed meal of animal origin according to the current standard[6]; sampling, sample preparation and bacteriological analysis of feed meal of animal origin according to the current standard[7]
We have proposed steam sterilization at the final stage of processing of waste raw materials, i.e. after the fine grinding process
Summary
Due to their biological usefulness, raw materials and feed of animal origin are a good nutrient medium for the development of various microorganisms. Despite the fact that the mode of sterilization of raw materials for the production of feed guarantees obtaining semi-finished products (shkvara), free from pathogenic forms of microorganisms, in the domestic and foreign literature reports on the contamination of feed by bacteria of the group of E. coli, Salmonella, toxigenic anaerobes are reported[1,2,3,4]. The effect on feed meal of animal origin of high bacterial contamination has not been studied enough. The presence of various bacteria in the feed meal of animal origin can provoke various diseases with the necessary involvement of medical and social assistance services[5] and adversely affect the productivity of farm animals and birds. One of the main requirements for the quality of feed meal of animal origin is to obtain feed meal of animal origin of high biological value
