Résumé
Background: study on the effects of some additives to reduce the negative effects of physiological stress in poultry
Objectives: this study was conducted to investigate the effects of the dietary synbiotic Biomin-IMBO and electrolytes-multivitamin solution in drinking water on performance of Japanese quail under physiological stress
Methods: a total of 240 one-day-old Japanese quail [Coturnix Coturnix japonica] were randomly assigned to 4 treatments with 4 replicates and 15 birds each. Experimental diets were 1- diets based on corn and soybean meal [negative control], 2- basal diets+ dexamethasone [positive control], 3- positive control+ 1gr/kg diet Biomin-IMBO[registered sign], 4- positive control+ 2 ml/li water electrolyte-multi vitamin
Results: physiological stress significantly reduced feed intake and live body weights of quails [p<0.05]. Feed consumption of stressed bird increased by adding electrolytes-multivitamin to drinking water [p<0.05]. Dietary Biomin-IMBO supplementation decreased significantly heterophil:lymphosyte ratio in blood of stressed birds [p<0.05]. The concentration of glucose in serum of positive control and water electrolyte-multivitamin group were lower than birds in negative control at stress period [p<0.05]
Conclusions: dietary Biomin-IMBO supplementation could reduce negative effect of physiological stress in Japanese quails
