Chichik R. Digestibility of fodder metabolism and productive qualities young rabbit at different levels of exchange energy and crude protein in mixed fodder.

Object - young rabbits of breed silvery meat-fell of a direction of productivity at different levels of metabolizable energy, crude protein and AES in ration. The purpose - to establish optimum levels of metabolizable energy and crude protein in mixed fodders for young rabbits and to determine efficacy of use in their structure of new biologically awake additive. Methods - zootechnical, biophysical, chemical, biochemical, microbiological and statistical. Novelty - for the first time is installed requirement of young rabbits for metabolizable energy and a crude protein depending on age. New data about influence of different levels of metabolizable energy and a crude protein in mixed fodders on productive qualities and a metabolism of young rabbits are obtained meat-fell of a direction of productivity. It is proved efficacy of use AES in feeding young rabbits and optimum levels of its introduction in structure of mixed fodders are certain. Results of researches - are used in practice, educational processand research work. Branch - animal industries.
