Efficiency of using a domestic feed additive in preventing eimeriosis in broiler chickens

The effectiveness of using a feed additive containing plant extracts in the treatment and prevention of poultry eimeriosis has been scientifically substantiated in comparison with the existing scheme for combating eimeriosis. Introduction of a feed additive based on a plant component into the diet of broiler chickens from the age of 3 days to 42 days of maintenance contributed to a 2.5-fold decrease in the number of oocysts in the bird's droppings compared to the control group. The feed additive contributed to an increase in the live weight gain of broilers compared to the control group by - 7.8 %, the average daily gain increased by - 7.9 %, while the gross feed consumption decreased by 7325 g and feed consumption per head by 42.6 g. The plant feed additive reduces the intensity of intestinal damage in broiler chickens caused by eimeria. The intestinal damage assessment, according to the Johnson and Reid scale, on the 10th day of the experiment was 0 points, while in the control - 3 points. According to the histological examination of intestinal tissues, it was found that the feed additive not only effectively reduces the number of oocysteine in the intestinal lumen, but also stimulates the development of immune reactions in tissues and promotes the restoration of the intestinal mucosa.
