ABSTRACT

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.

摘要

这篇文章介绍了数据，这些数据证实了用于饲养Lo牛的膨化龙骨（ELM）粕的功效。该实验基于收集蝗虫，饲养ste牛和计算经济效益。将一百头ste牛白头牛品种平均分为两个处理组，并饲喂基础饲粮（BR，对照组），或饲喂含10％ELM完全饲料的饲粮（试验组）。在研究的人群中，观察了体重动态，并控制了生理状态和血液学状态。根据控制屠宰的结果，研究了公牛的肉生产率和肉质。
