METHOD FOR OBTAINING VITAMINIZED FEEDSTUFF FOR LAYING HENS Russian patent published in 2007 - IPC A23K1/16 

FIELD: poultry science.

SUBSTANCE: the present innovation deals with technologies for preparing the feedstuff due to supplementing the feedstuff with vitamin-pigmenting additive. Moreover, as such an additive one should apply a protein-vitamin concentrate out of alfalfa juice and gourd paste at equal weight portions with addition of culture liquid of lactic-fermentation bacteria for fermenting at concentration of 0.1-0.3%, it should be added then to the feedstuff at the quantity of about 3-5% against the feedstuff weight before feeding. The innovation enables to decrease cost price of dietary egg production and increase the safety of stock in laying hens, obtain ecologically safe production due to applying natural sources of vitamins and pigments and pigmentation of hen's eggs and, also, improve commercial quality of eggs.
