INFLUENCE OF FLAX CAKE ON PHYSIOLOGICAL STATE OF YOUNG CATTLE AND DIGESTIBILITY OF FEED NUTRIENTS

Abstract

Sunflower and soybean meals, which contain a wide range of minerals, amino acids and proteins, are used as a basis for the preparation of compound feed. However, they are imported from abroad, which significantly increases the cost of manufactured products and reduces the efficiency of the livestock industry. With that in mind, it is reasonable to look for alternative sources of protein among available local raw materials, in particular, oil cake. The article contains the materials of research, the purpose of which was to study the influence of different levels of oil flax cake on physiological state of young cattle, digestibility and utilization of nutrients. In the course of the research, the optimal input rate of oil flax cake as a fully-featured substitute for sunflower meal in compound feed for calves has been established, which is 20% by weight, providing an increase in the digestibility of dry matter of diets by 1.7 p.p., crude protein – by 0.5, fiber – by 4.3, fat – by 6.1 p.p., along with improving the use of nitrogen by 1.7 p.p.
