ABSTRACT
Development of anticoccidial resistance and concerns of drug residues have prompted the evaluation of alternatives to allopathic drugs. In current study, anticoccidial effect of amprolium was compared with that of Curcuma longa and Zingiber officinale. Ninety (90) sheep, naturally infected with Eimeria spp. and having a minimum oocyst per gram (OPG) count of faeces above 5000 were randomly selected and divided into six groups of 15 animals each. Animals were supplemented with amprolium @ 62.50 mg/kg body weight (bw) (GI), turmeric @ 200 and 300 mg/kg bw (GII and GIII) and ginger @ 200 and 300 mg/kg bw (GIV and GV), orally for 7 days and GVI animals were kept as untreated infected control. Faecal samples were collected on '0' day before treatment and on 8th, 14th, 21st and 28th day after starting treatment and evaluated using Faecal oocyst count reduction test (FOCRT). The efficacy of amprolium was 93.18%, 96.82%, 95.56% and 95.80% on 8th, 14th, 21st and 28th day, after starting treatment. Turmeric @200 mg/kg b.w. showed efficacy of 41.49%, 52.37%, 61.47% and 60.08% and turmeric @ 300 mg/kg bw was 44.92%, 54.32%, 64.21% and 61.95% effective on 8th, 14th, 21st and 28th day, respectively. Ginger @200 mg/kg bw showed efficacy of 38.51%, 53.48%, 55.38% and 55.53% and ginger @ 300 mg/kg bw was 39.65%, 54.81%, 57.18% and 58.22% effective on 8th,14th, 21st and 28th day, respectively. The results justify use of amprolium for clinical coccidiosis while Curcuma longa and Gingiber officinale could be used as natural prophylactic alternatives.
