Hunchak A. Influence of biogenic additives on metabolic processes and productivity of poultry

Object - physiological and biochemical processes in the poultry of different species and productive groups. Purpose - determination the effects of different doses of dietary supplements (iodine and tincture of eucalyptus leaves) to diets of different species and productive groups of poultry on intensity of the metabolic processes. Methods - biochemical, physiological, microbiological, immunological, histological, morphometric, statistics. Novelty: for the first time have conducted the system research of the effect of iodine and eucalyptus leaves tincture on the intensity of protein, carbohydrate and lipid metabolism, quantitative and qualitative composition of intestinal microorganisms, indices of antioxidant status and T-and B-cell immunity, histological structure of organs, productivity, reproductive function and production quality of different types and productive groups of poultry. Results: theoretically and experimentally proved the advisability of increasing the iodine in the diet of poultry for normalization of cecum microbial biocoenosis and morphological structure of the thyroid gland, improving the quality of eggs by increasing of minerals content (Ca, I, Mg, Zn, Cu) in egg yolks and intensification of metabolic processes in embryos. The optimal amount of iodine in the diet of laying hens, Japanese quails, turkeys and geese have been found. Experiments in vitro showed that tincture of eucalyptus leaves has bactericidal activity for strain of Escherichia coli from hen ceccum. Positive effect of eucalyptus leaves tincture on laying hens and eucalyptus leaves tincture with ascorbic acid on broiler chickens for normalization of gut microorganisms biocoenosis, activation of protein, carbohydrate and lipid metabolism and digestive processes, reducing the intensity of lipid peroxidation, stimulation of T-and B-cellular immunity, increasing productivity have been pointed. Developed and tested schemes and doses for herbal medicine.
