Development of technology for producing protein feed powder from animal hides at «SK-PROTEIN» LLP in North Kazakhstan

The article focuses on developing a technology for producing protein feed powder from leather raw material waste in North Kazakhstan. The goal is to enhance animal and poultry productivity by incorporating this powder into mixed feeds. The necessity of domestic feed additive production and utilization of livestock waste is emphasized. Animal-derived feeds are noted for their richness in essential amino acids and vitamin B12. Data on the chemical composition of leather raw materials, showing high protein content, are presented. Developed methods enable the production of feed powder with approximately 82% protein, which reduces costs and improves economic performance.
