The research target was the parent flock of broiler cross Ross-308; the age - from 52 to 61 weeks. Two groups of 1000 birds were formed; where the 1st group was the control and received the basic diet (complete formula feed), and the 2nd group was a trial group, in addition to the basic diet, the 2nd group received the ProActiv’ Poultry feed supplement in a dose of 1 kg t. The gross egg yield in the 2nd group was by 3.1% higher than in the control group. The hen housed egg production in the groups was at the level of 45.1-46.5 eggs. The surplus of the trial group compared to the 1st group made 3.1% or 1.4 eggs. The percent settable eggs and fertilized eggs are important indices of the reproductive qualities of the parent flock. These indices in the 2nd (trial) group exceeded those in the control group by 6.7 and 1.2%, respectively. It was found that in the 2nd group, the number of contaminated eggs was by 2.92% less than in the control group. Survival in the trial group was by 2% higher than in the control group. The inclusion of the ProActiv’ Poultry feed supplement in the diet of the 2nd (trial) group contributed to increase of the total egg yield, percent settable eggs, fertilized eggs and bird survival, respectively, by 3.1; 6.7; 1.2 and 2.0%, and the number of contaminated eggs decreased by 2.92%. The greatest economic effect was obtained in the trial group and amounted to 35.0 rubles per head.
