Abstract The present work was performed to study the effect of toltrazuril, probiotic and thyme essential oil on growth performance, immunity, antioxidant enzyme activity and blood parameters on Eimeria spp. infected and non-infected quails. One hundred and sixty eight one day old quails were used in this study. The birds were divided into eight equal groups. group (1) was kept as normal control. group (2) administrated probiotic (1 gm/L drinking water) from one day till 28 days old. group (3) supplemented with thyme essential oil 450 mg/kg mixed with the diet from one day till 28 days old. group (4) administrated toltrazuril at 16 days old at a dose of 25 ppm (1 ml/L drinking water) for 2 consecutive days. group (5) experimentally inoculated intracrop with 4.1 x 104 sporulated oocysts of Eimeria spp. at 14 days old. group (6) administrated probiotic (1 gm/L drinking water) from one day till 28 days old and experimentally inoculated intracrop with (4.1 x 104) sporulated oocyst of Eimeria spp. at 14 days old. group (7) supplemented with thyme essential oil 450 mg/kg mixed with the diet from one day till 28 days and experimentally inoculated intracrop with (4.1 x 104) sporulated oocyst of Eimeria spp. at 14 days old. group (8) experimentally inoculated intracrop with (4.1 x 104) sporulated oocyst of Eimeria spp. at 14 days old and treated with toltrazuril at 16 days old at a dose of 25 ppm (1 ml/L drinking water) for 2 consecutive days. |
