A-G. Statistical analysis of body weight in chickens from control and experimental groups. Group P – supplemented with the probiotics Enterococcus faecium, Lactobacillus casei, Lactobacillus plantarum and Pediococcus acidilactici; prebiotic fructooligosaccharides and the prebiotics inulin, maltodextrin and oligofructose; vitamins B1, B2, B3, B5, B6, B12, C, K3 and folic acid, and glucose and silica; Group AO – treated with the antibiotics enrofloxacin, fortamox and trimsulfasol; Group P&AO – supplemented with probiotics, prebiotics and vitamins and treated with antibiotics; Group C – not supplemented nor treated with antibiotics. Statistical analysis was carried out using the Mann–Whitney U test and where possible, Student’s t-test. The normality of distributions was tested with the Shapiro-Wilk test, and the homogeneity of variance with Levene’s and the Brown-Forsythe tests. The relationships described a level of α = 0.05
