Optimization of Technological Parameters of Compound Feed Production with the Introduction of Feed Enrichment Concentrate

Improving the efficiency of pelleted compound feed production requires optimizing process parameters while considering the use of new protein components that provide high nutritional value without compromising technological properties. The aim of the study was to optimize the parameters for producing pelleted compound feed using a feed enrichment concentrate (FEC) based on natural, multi-protein raw materials of animal origin. The study examined the effects of mixing duration, feed mixture moisture content before pelleting, and the FEC addition rate on pelleted feed quality. Process efficiency was assessed based on feed mixture homogeneity, pellet strength and crumbliness, and key chemical composition indicators. The optimal mixing duration was 9 minutes, while the most favorable moisture content before granulation was 16%, ensuring high mixture homogeneity, maximum pellet strength, and minimal crumbling. The introduction of FEC did not negatively affect production processes or the physical and mechanical properties of pelleted feed compared to the control. At the same time, FEC increased crude and digestible protein and crude fiber content while maintaining high energy value. The 20% FEC treatment was the most effective, confirming the feasibility of its industrial application.
