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 18o-19oC 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%).
