One hundred and sixty day-old broiler chicks, procured from a recognized hatchery, were divided into eight groups, of 20 birds each as, CA-Normal feed, CB-Salinomycin @ 1 kg/ton of feed, CC-Coxynil @ 250 mg/kg of feed and CD-Coxynil @ 300 mg/kg of feed and respective infected groups as IA, IB, IC and ID. The birds were maintained on deep litter system and standard managemental practices were followed. Oocysts challenge, with sporulated oocysts, of E. tenella @ 20,000 oocytes/bird was carried out at the age of 21 day. BOdy weights were significantly less in infected groups (748.32, 749.97, 875.3 and 919.67 g in IA, IB, IC and ID, respectively) than the respective control groups (1055.4, 983.23, 1098.6 and 1148.9 g in CA, CB, CC and CD, respectively). After oocysts challenge,FCR in infected groups were higher than respective control groups. Both the coccidiostats used in the study delayed the appearance of clinical symptoms as compared to infected control group (IA). Mortality was observed only in IA (15) and IC (5). Average OPG was highest in IA (10.44 x 10¦4) followed by that in IC (10.07 x 10¦4), ID (8.83 x 10¦4) and IB (7.07 x 10¦4). Haemorrhages, blood clots and distension of caeca, on 6 DPL and caecal core formation and thickening of caecal wall, on 9 DPI, were the prominent gross findings in IA. Caecal lesion score on 6 DPI was highest (+3.66, +2.33, +4.0 and +3.66 in IA, IB, IC and ID, respectively) in the infected groups. Microscopically, catrrhal e
nteritis was evident in all the infected groups, on 3 DPI. Denuded epithelium, large number of schizonts and gametes, along with haemorrhages (in mucosa and submucosa), on 6 DPI and exfoliated epithelium along with oocyts in mucosa, on 9 DPI, were the prominent alterations in group IA, ANAE cell counts, on 9 DPI, were significantly higher in infected groups than the respective control groups and significantly lowest in IA, amongst all the groups. Herbal ration and it reduced the severity of lesions. It was effective as a feed additive and coccidiostat.
