In this paper are analysed productive and reproductive results (eggs and broiler chicken production) of heavy hybrid of poultry Arbor Acres an the farm Pile Produkt - LTD, Mladenovac, Serbia (Serbia and Montenegro), with a special attention on the influence of ages (operation period) of family flock on the lay magnitude and percent of incubates chicks. Exploitation period of family flock was 44 weeks, from 23rd to 66th week of age. Productive period was long enough for calculating of phenotypics correlations. According the results we can conclude that productive results of family flock of heavy hybrid in the most of productive and reproductive attribute accomplished the satis-factory results, with a recommendation to production period is to be less than 44 weeks. This statement is confirmed by calculated phenotypic correlation coefficient and level of a statistical significance between ages and lay magnitude and percent of incubates chicks.
