Abstract

The article deals with the actual problem of optimising the production of fodder for farm animals by using secondary raw materials of the meat industry. The aim of the work was to study the possibility of using low-value and secondary raw materials of the meat industry to create protein-mineral-vitamin supplements (PMVD) and assess their effect on feed quality and animal performance. The conducted experiments included selection and analysis of meat raw materials, development of BMVD formulations, production of pilot batches with the use of specialised equipment, as well as evaluation of their influence on mixed fodders and efficiency of feeding different types of animals. It was found that bone residues, cartilage and tendons are valuable sources of protein, fats and minerals. The developed formulations of BMVD contained optimal proportions of meat raw materials, cereals, amino acids and vitamins. The production was carried out on a technological line including a flour mixer, extruder, dryer and application machine. Extrusion contributed to the improvement of protein digestibility. The use of BMVD in animal diets led to an increase in egg production of hens, weight gain of pigs, reduced feed costs and increased digestibility of nutrients, confirming the prospects of this direction.
