Advanced feeding methods are used to maximize poultry productivity on an industrial scale. The use of genetically improved poultry crosses in combination with optimally balanced feeds makes it possible to achieve significant results in the production of poultry products. The main components supplying protein are soybean meal and fish meal, most of which are purchased abroad and are of satisfactory quality. Finding alternative protein sources can help overcome shortages and reduce dependence on imports.
One promising option is the white lupine. Its advantages include a high protein content, high yield potential, drought resistance and a small amount of fiber. As part of a scientific study aimed at reducing the level of anti-nutritional substances, lupine seeds were processed using the barohydrothermal method and enriched with yeast.
In a scientific study on ducks of the SK-6 cross, the effect of treated lupine seeds on productivity was studied. In the conditions of the Penza State Agrarian University vivarium, three groups of birds with 20 heads each were formed according to the principle of pairs of analogues. The poultry of the control group received standard compound feed. For the poultry of the first experimental group, the standard compound feed was replaced with 25% treated lupine seeds, which make up the weight of soybean meal in the diet. The second experimental group received standard compound feed, in which part of the soybean meal (50%) was replaced with treated lupine seeds. As a result of adding treated lupine in the diet in the first experimental group, there was a significant increase in the concentration of total protein in the blood serum of ducks by 6.8% compared with the control. There was a tendency to increase in the live weight of ducks of the first experimental group by 4% compared with the control group. It has been established that the most optimal dose for introducing barohydrothermal treated lupine followed by yeast enrichment into the diet of ducks is 25% replacement of soybean meal with this type of feed mixture in the poultry diet. The results obtained indicate that the issue of expanding the feed raw material base for protein components requires continued research and a comprehensive approach, including the development of advanced technologies for treatment of lupine seeds, the selection of new crop varieties with a reduced content of alkaloids, as well as optimizing the formulation of feed, taking into account the specifics of all components used.
