FIELD: veterinary science. ^ SUBSTANCE: the present innovation deals with cooling selected fertilized uninfected eggs at 2-4 C up to 7 d followed by homogenization, diluting with physiological solution of egg mass, bactericidal treatment, conservation with phenol solution up to its concentration being 0.3% at subsequent filtration of target product. Moreover, egg mass should be diluted with physiological solution at the ratio of 1:5, then comes thermal treatment upon water bath at 70-80 C for 1 h and before conservation one should cool the target product in bactericidal chamber under the lamp with ultraviolet irradiation for 30-40 min. The method provides increased total and specific body resistance, it enables to obtain cheaper and more acceptable biostimulant and simplified way for preparing. ^ EFFECT: higher efficiency. ^ 4 ex, 3 tbl |
