Abstract
The research was done on a batch of 1344 incubation eggs, descending from the meat chicken commercial hybrid „COBB-500”; out of these 4(four) work modules were made, each containing 336 eggs, respectively A, B, C and D module. The eggs included in the A, B and C modules were decontaminated with a new abstergent substance of Romanian nature named Sodium dichloroisocyanurate, 0,6g ‰ a.s. solution(A module), 0,4 g ‰ a.s. solution(B module), respectively 0,2 g ‰ a.s. solution(C module) while the D module eggs have not been decontaminated. The decontamination technique is regulated and consists of immersing the eggs in decontamination solution, in temperature stages, to assure the mineral shell dilatation and the closing of the pores, so that this solution does not get inside the egg. The decontamination efficiency was assessed by bacteriological exams, both quantitative and qualitative. Decontaminated eggs were incubated alongside contaminated ones, rating the specific incubation indexes. Incubation egg sanitation constitutes a determinant factor, both by assuring a high level of hatching and by the ulterior health state of the chicks. The analyzed chicken eggs displayed a constant germ contamination, but with very wide variation limits, covered between 31 and 382 germs/cm2. The hatching percentile of eggs varied between 89.43% for the C module and 92.48% for the A module.
