The aim of this study was to develop a method for the prediction of broiler chicken hatchability on the basis of the biological control of eggs. The incubation of Ross-308 cross-bred eggs was carried out during the period from 2011 to 2016. A formula for predicting broiler chicken hatchability for the current program of maintenance of the parent stock and egg incubation mode was obtained using the results of egg incubation analysis. The difference between the observed and expected hatching rates fluctuated within a range of -0.1 to +1.3 %. The hatchability prediction of broiler chickens according to the proposed formula based on the results of biocontrol for 0-11 days is accurate enough to be recommended for use at enterprises producing and selling dayold Ross-308 cross-bred meat broiler chickens.
