In materials of the article the question of influence of unconventional feed raw material of phytogenous (dry apple pomace) is reflected on content of nutrients and bioactive substances in geese’s yolks. This feed addition, that was to the last time considered useless for this aim, contains in the composition many valuable substances, that can enrich the ration of bird. However, an increase level of raw cellulose of dry apple pomace (about 27.79%) something restrains introduction of them in the complement of the mixed fodder for a bird. However, geese are able to arrive at the corresponding level of the productivity after small concentrated as feeding. But in an order to promote ability of tribal bird effectively to use the nutritives of this vegetable feed, there was a necessity of application of enzymic preparation. In particular, the use of enzymic preparation in the conditions of increase of unconventional digister, that has high nutrients qualities resulted in the increase of maintenance of vitamins (BAS) in geese’s yolks under the action of enzyme. Investigating maintenance of vitamins it was set in egg, that in yolks of eggs under the action of this addition the amount of vitamin А grows for certain – on 1,01 –1,73 mgr /g and vitamin of В2 – on 0,51 – 0,78 mgr /g that specifies on the better biological full value of goose eggs. It allows to get the better results of the productivity, in particular bearing rises on 17,5 %, and hatching of gooses on 9,0 %.
