Heat-treated lupine in the diets of Lohmann Brown-Classic laying hens

Abstract

In the diets of laying hens, readily available protein is the second most important nutrient in cost. With the development of the poultry industry, the need for good and high-quality feed also increases. Soybean and sunflower meal and oil cakes, which are familiar to us, cannot fully provide egg-based poultry farming with protein. This publication discusses the replacement of soybean meal and sunflower meal with heat-treated lupine in the diets of laying hens. The correction of the diet with the introduction of heat-treated lupine - 3% and the data obtained in the course of the process is analyzed. To study the effect of lupine on the productivity and safety of birds of the Lohmann Brown-Classic cross, a scientific and economic experiment was carried out, where two groups of birds were selected. The control group received the main diet without lupine, and the experimental group received the diet with heat-treated lupine. In the experimental diet, soybean meal and sunflower meal were partially replaced with heat-treated lupine. Partial replacement of heat-treated lupine in diets for laying hens showed positive dynamics, namely, an increase in egg productivity and safety. Replacing soybeans and sunflowers with lupine reduces the cost of the diet.
