An experiment using 22 440 broiler chickens(Ros-308) was conducted to assess the influence of the commercial preparation Rescue Kit SL (containing Bacillus licheniformis and Bacillus subtilis, betaine, vitamins and microelements), administered in the drinking water (1g/litre) from the age of 9 to 14 days. One group, constituted by the same number of chickens, that were not given the additive, was considered as control. Performance indices were measured weekly and blood samples were collected from 14, 35 and 50-d-old chicks for biochemical and hematological analyses. The results indicate a reduced lethality rate in experimental group - 3.5%, while 3.9% (control).At the end of the production cycle (50 days) the body weight was by 50 g (P 0,05) higher in broiler chickens from the experimental group. The preparation Rescue Kit SL induced the increase of erythrocytes, hemoglobin, total protein and glucose in blood serum, resulting from the intensification of metabolic processes.
