Realization of bioresource potential of hens of parental herd of broilers against the background of immunocorrection

The biological preparation is developed Prevention-N-С and veterinary and hygienic justification of expediency of its application in comparison to earlier tested medicine PS-7 for realization of bioresource potential of productive qualities of hens of parental herd of broilers of a cross of Hubbard F-15 due to activization of cellular and humoral factors of nonspecific resistance of an organism is given. The approved biological preparation raise a amount of the laid eggs of hens that is shown in its intensive increase during an initial stage of efficiency and earlier achievement of peak of a egg production. The intensity of a egg production of hens of the 1st (56,79±0,70%) and the 2nd (57,61±0,79%) was higher than skilled groups of parental herd of broilers in comparison with control (54,03±0,67%) for 3,58 and 2,76% respectively (Р
