In order to save soybean meal, sunflower oil and reduce the cost of rations, new sources of raw materials can be used. In modern conditions, attention is drawn to the brassica rapa campestris, the seeds of which can be used as a fat and protein supplement. Experiments were carried out to determine the optimal rate for the introduction of seeds of spring rape variety Nadezhda into compound feed for growing broiler chickens. It has been established that this variety belongs to canola varieties and can be included up to 7% (by weight) in the composition of mixed fodders, does not have a negative effect on the state of the body and the growth rate of broiler chickens. The introduction of seeds of spring rape to 7% in the composition of feed for broiler chickens reduces the use of soybean meal to 4.7% and sunflower oil to 2.3% (relative). The efficiency of conversion to products by group was 61.93 % in the control group and 62.18% to 63.62% in the experimental group, respectively.
