The effects of Enterococcus faecium EF55 and Salmonella enterica serovar Enteritidis phage type 4 (SEPT4) on the biochemical parameters and the weight of the organs were studied in chickens. Experiments were carried out on chickens of the hybrid ISA BROWN which were divided into four treatment groups (C — control, SE — Salmonella Enteritidis PT4, EF — Enterococcus faecium EF55, EFSE – S. Enteritidis PT4 + E. Faecium EF55) which lasted for 22 days. For analysis, the blood and internal organs were collected on days 8 and 22. The biochemical parameters were determined spectrophotometrically and the organs were weighed on laboratory scales. The Salmonella infections and probiotic cultures affected significantly (P less than 0.05) the concentration of the total bilirubin (decrease in groups SE, EF, EFSE vs. C in 8-day old chickens; increase in groups SE, EFSE vs. C and in SE vs. EF in 22-day old chickens), glucose (decrease in groups SE, EFSE vs. C and in EFSE vs. EF in 8-day old chickens; decrease in EF vs. SE, increase in groups SE, EFSE vs. C and in EFSE vs. EF in 22-day old chickens), enzymatic activity of alanine aminotransferase (decrease in groups EF, EFSE vs. SE and increase in SE vs. C in 8-day old chickens; decrease in EF vs. SE, increase in group SE vs. C and in EFSE vs. EF in 22-day old chickens) and relative weight of the pancreas (decrease in EF group vs. SE, increase in groups SE, EFSE vs. C and EFSE vs. EF in 8 dayold chickens) and of the spleen (decrease in EF vs. SE, increase in groups SE, EFSE vs. C and in EFSE vs. EF in 22 day-old chickens). Our results demonstrated the appropriateness of the use of probiotics to improve digestive processes and metabolism in chickens.
