MEZDRA FEASIBILITY STUDY FOR PRODUCTION OF FODDER PRODUCTS

Abstract

The article presents the results of studies to determine the possibility of using mezdra for the manufacture of feed products. It has been established that mezdra obtained using the current technology for processing leather raw materials at Minsk Production Leather Association LLC is a significant source of essential nutrients necessary to maintain the vital functions of animals. (protein content - 8.0%, fat - 7.2%, calcium - 1100.0 mg/100 g, magnesium - 18.2 mg/100 g, potassium - 26.5 mg/100 g, sodium - 185.9 mg/100 g, iron - 16.9 mg/100 g, copper - 0.4 mg/100 g, phosphorus - 216.0 mg/100g, monounsaturated fatty acids - 56.25%, polyunsaturated fatty acids - 1.35%, saturated fatty acids - 42.39% of the total fatty acids), characterized by rational functionaltechnological and structural-mechanical indicators (fat-binding capacity - 61.9%, emulsifying capacity - 50.0%, emulsion stability - 91.0%, moisturebinding capacity - 31.8% (to sample weight), 49.9% (to total moisture), water-retaining capacity - 42.0%, moisture-releasing capacity - 20.0%, ultimate shear stress - 1028.7 Pa), and in terms of safety indicators meet the requirements of regulatory legal acts, which indicates the possibility of using this by-product of the leather industry for the manufacture of feed products and confirms the relevance of further research aimed at developing the technological basis for the manufacture of feed and feed additives based on mezdra.
