Семена сурепицы в кормлении цыплят-бройлеров

Abstract

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 spring colza, the seeds of which can be used as a fat and protein supplement. A limiting factor in the use in poultry nutrition is the presence of glucosinolates in the seeds and erucic acid in the oil, which negatively affect the growth and development, especially of young animals. Breeding work aimed at improving the feed qualities of spring colza seeds contributes to a wider use in the composition of diets for poultry. In growth experiments on broiler chickens the rate of introduction of seeds of spring colza of the 'Nadezhda' variety selected by the Federal Williams Research Center of Forage Production and Agroecology. It has been established that this variety belongs to the "canola" varieties, and its seeds can be included up to 7% (by weight) in the feed composition without adversely affecting the state of the body and the rate of growth of live weight of chickens. The use of colza seeds reduces the use of soybean meal to 4.7% and sunflower oil to 2.3 % (relative). Increases the efficiency of feed in the control up to 61.93% and in the experimental groups (I, II, III, IV) – 62.18, 62.51, 63.62, 62.78%, respectively. The seeds of the spring colza variety 'Nadezhda' satisfy the bird's need for nutrients and ensure equal productivity with the control
