Description
Summary:The article presented the data that confirm the efficiency of the extruded Locusta migratoria (ELM) meal used in feeding steers. The experiment was based on collecting locust, feeding steers and calculation of economic efficiency. One hundred steers of Kasakh white-headed breed were equally divided to 2 treatment groups, and fed either a basal ration (BR, Control group), or a ration containing complete feed supplemented with ELM at 10% (Test group). In the population under study, the live weight dynamics was observed, and the physiological state and haematological status were controlled. The steers' meat productivity and meat quality were studied on the results of the control slaughter. Partial replacement of the feed with locust reduced the feed costs and contributed to an increase in profits per animal in Test group compared to the control animals, as well as in the beef production profitability.
