Maximizing efficiency in poultry farming requires the considerable improvement of organizational and technological processes at poultry farms. Poultry farms and feed mills have to control diet composition to in-crease the poultry genetic potential with the high-quality feedstuff and the cost-effective approach. Quality requirements in the modern poultry industry depend on the level and quality of protein feeding. Protein is the main micronutrient for high-quality meat. Currently, the alternative plant protein sources are becoming highly important, such as white lupine seeds, which contain 33-39% protein. Lupine is a relatively new crop in the Penza region. Therefore, it is necessary to study the possibilities of lupine cultivation in the Penza region, as well as technological methods of white lupine seeds treatment to provide nutrition to poultry birds and im-prove their digestion.
The research, carried out by the Penza State Agrarian University scientists, confirmed the hypothesis that partially replacing soybean meal with barohydrothermally treated lupine seeds had a beneficial effect on the metabolic processes of poultry, facilitating the genetic potential of broiler chickens. Since feed accounts for the majority of production expenses, it was noted that in the group where 50% of soybean meal protein was replaced with treated lupine protein, expenses decreased by 3.75% compared to the control group. This cost reduction directly impacts production costs. The cost per kg of the carcass in the second experimental group was 17.8% lower than in the control group, and 3.2% lower than in the first experimental group. Includ-ing lupine in animal diets, along with processed soy or sunflower products, gives new opportunities for feedstuff improvement. It could allow feed producers to use more affordable feedstuff resources and reduce expenses significantly.
