Sukharenko O. Influence of Antioxidants preparations on Exchange Substances, Digestibility Feeds and Duck Productivity

Thesis contains theoretical and experimental material on the use of antioxidant preparations stibil and distinol in duck feeding rations. It is defined that inclusion of antioxidant preparations stibil and distinol influences on the increase of daily average weight gain, preservation of stock, reduce of combined feeds cost per 1 kg of daily average weight gain, positively influences on digestibility of feed nutritive matters, nitrogen exchange. Productive qualities of layers, morphological, chemical content and indices of egg incubation have been studied. Influence of antioxidants on functional condition of blood and liver has been defined. For the increase of productivity and digestibility level of nutritive matters of duckling feeds it is recommended to use combined feeds with additive of stibil in amount of 1-2% from feed mass or distinol - 0,025% from feed mass. Additives should be included on the 7th day of age till 35-42 days.
