Development and use of low-expenditures compound feed in poultry feeding

Abstract

The purpose of the research was to develop and study the effect of the use of lowexpenditures compound feed in poultry feeding on hematological and biochemical blood parameters. In order to achieve this purpose, three scientific and economic experiments were carried out on the development and use of low-expenditures compound feed in the feeding of Haisex Brown egg cross poultry. Two experiments were carried out under the conditions of the Scientific and Research Center safety and effectiveness of feed and additives of the Federal State Budgetary Educational Institution of Higher Education “Volgograd State Agrarian University”, the third experiment was conducted at the AO Volga Poultry Farm in the Sredneakhtubinsky area in the Volgograd region. The first experiment included the study of the effect of the anti-stress additive Feed-Food Magic Antistress Mix, in the second scientific and economic experiment the use of the Availa Cr mineral complex was studied, and in the third experiment the research was conducted to study the effectiveness of using lupin grain instead of full-fat soy in the diets of laying hens. The inclusion of the Feed-Food Magic Antistress Mix additive in the diet of egg-bearing poultry contributed to an increase in the number of red blood cells. So, their indicator was in the experimental group at the level of 3,96×10¹²/l, in the control group it was in the range of 3,55×10¹²/l, there was then increase in the concentration of hemoglobin in the experimental group by 5,82 g/l. The use of the Availa Cr mineral complex allowed to increase the hematocrit level in the blood of egg poultry by 1,38 %, to reduce the number of leukocytes in the experimental group by 0,38×10⁹/l. The inclusion of lupine grains in the diet contributed to the increase in the number of red blood cells by 0,14×10¹²/l, the increase in total protein in the blood by 2,65 g/l, the increase in the level of carotene and vitamins A and E.
