The use of a fatty acidphospholipid complex in the cultivation of broiler chickens

Phospholipids make up the structure of cell membranes and organelles, influencing the activation of cellular enzymes. They are involved in the intercellular transport of fats, fatty acids, cholesterol and other substances in blood lipoproteins. These compounds, being natural metabolites, contribute to more efficient use of fat and prevent its excessive accumulation in tissues. Phospholipids have emulsifying properties, of particular interest are lecithins, which are phosphatides. Lecithin-based supplements in poultry feeding improve growth, reduce the risk of perosis, have a beneficial effect on skeletal formation and accumulation of vitamin A in the liver (lecithin has a synergistic effect). They also protect farm poultry from the development of liver obesity syndrome. The aim of the research was to study the effect of the phospholipid-fatty acid complex on the main zootechnical indicators in the cultivation of broiler chickens. Partial replacement of sunflower oil with fatty acids at various age periods by 0.69–1.48 % and phospholipids by 0.84–1.8 % (according to the experimental scheme) contributes to an increase in the safety of broiler chickens by 2.5 %. The inclusion of a phospholipid-fatty acid complex in broiler diets is advisable, which is confirmed by an increase in live weight by 1.95–7.42%; a decrease in conversion by 0.01–0.02 kg/ kg; preservation of safety indicators at the level of 97.5–100 %; an increase in income from the sale of chickens by 4.57–7.42 %; making a profit of 52.60–104.98 % more in comparison with the control; increasing the level of profitability by 1.01–2.19 %.
