Antibiotics, Constituents, Hematocrit, Hemoglobin, Oxytetracyclin, Supplement, Tylosin Phosphate


The present research was conducted to evaluate the effect of growth promoter antibiotics Oxytetracyclin and Tylosin Phosphate, alone and in combination, to study the physiological indices of broiler chicken. For this purpose, 405 day-old broiler chicks were randomly divided into nine treatment groups in 32 factorial arrangements. The results showed that the use of Oxytetracycline and Tylosin Phosphate as an antibiotic growth promoter feed supplement resulted in a significantly higher count of red blood cells in treatment groups in comparison to control (P<0.05). While white blood cells, lymphocytes and other hematology constituents were noted to rise significantly among treatment groups (P>0.05).  The results of serum biochemistry parameters revealed that Oxytetracycline and Tylosin Phosphate improved hemoglobin concentration of treatment groups in comparison to the control (P<0.05). However, no significant difference was observed among groups in mean corpuscular volume, hematocrit and platelets (P>0.05). In conclusion it can be suggested that the use of Oxytetracyclin and Tylosin Phosphate as antibiotic growth promoter have no adverse effect on hematology and serum biochemical parameters observed in the present study.
