Kosyanenko O. Digestibility of fodder, metabolism and productive qualities of young rabbit at selenium influence

The dissertation presents theoretical and experimental data of using feed with various doses and sources of selenium for young rabbits. Revealed certain changes in growth efficiency of young rabbits. The estimation of morphological and biochemical structure of blood is done. Has been studied nutrients digestibility and nitrogen balance, calcium, phosphorus and selenium depending on a dose and source of selenium. The expediency of balancing of diets on selenium has been proved and its optimum dose feeding has been established. Has been shown influence of organic and inorganic selenium on efficiency, digestibility, morphological and biochemical indicators of blood, lethal qualities, aminoacid structure of the longest muscle of young rabbits silvery breed. Has been recommended to use feed with a level of selenium of 0,2 mg/kg in organic form - Sel-Plex optimum level of this trace element for young rabbits.
