The research was done on a batch of 1344 incubation eggs, descending from the meat chicken commercial hybrid "COBB-500"; out of these eggs, 1008 were decontaminated, in 3 work modules(A, B and C), each containing 336 eggs. The decontamination of the mineral shell of the studied eggs was made with a new substance, named Sodium dichloroisocyanurate. For the A module a 0.6g ‰ a.s. solution was used, for the B module a 0.4 g ‰ a.s. solution and for the C module a 0.2 g ‰ a.s. solution. The decontamination technique of the eggs contained four work stages: water wash, for the removal of impurities on the mineral shell; water rinsing; decontamination; the temporary holding of eggs at a 18°-19°C temperature. The hatched chicks from the treated eggs were studied over all the growth period, from day 1 to day 41, determining their quality, weight growth dynamic, food consumption, losses from the effective and the resulted meat production. The hatched chickens in A module became la L1exp. batch (279 heads) the ones from the B module - L2exp. batch (279 heads), and the ones from the C module - L3exp.(279 heads) in addition a control batch was formed - Lc(279 heads), with hatched chickens from untreated eggs. Incubation egg sanitation with Sodium dichloroisocyanurate, 0,4g ‰ a.s., proved to be the one with the best results in the growth of hatched chicks from the eggs treated this way (average live weight at 42 days - 2572,64 g; IC kg nc/kg gain - 1.84; losses in the effective 1.78%).
