Etiotropic approach to antibiotic therapy in broiler chicks
An example of the effective application of etiotropic approach to antibiotic therapy in broiler chicks is presented. Bacteriological analysis of samples isolated from broiler flock from South Russia at 23 days of age revealed the presence of 5 main pathogens: Е. coli, Mycoplasma synoviae, Ornithobacterium rhinotracheale, Staphylococcus aureus, and Enterococcus spp. The study on the sensibility of isolated strains to different antibiotics proved that the most effective preparations for this combination of pathogens would be Solutistin® and Pulmosol®. Control group of broilers (60 000 birds per group) was treated according to standard protocol of the farm; experimental group was treated with these preparations and an acidifying additive. European production efficiency factor (EPEF) in experimental group was higher by 17 points in compare to control due to better livability (mortality lower by 1.1% in compare to control), average daily weight gains (by 2.4%), and live bodyweight at slaughter (40 days of age, by 2.2% in compare to control).
