Anticoccidial activity of Curcuma longa L. in broilers

Comparative efficacy of turmeric (Curcuma longa L.) crude powder and salinomycin sodium on the occurrence of coccidiosis and growth performance of broiler was evaluated. A total of 90, day-old chicks were randomly divided into six groups. From first day onward, ration was supplemented with 1, 2 and 3 % turmeric powder in groups 2, 3 and 4, respectively, group 1 received salinomycin sodium @ 12 g 50 kg-1 feed while groups 5 and 6 were kept as infected un-medicated and uninfected un-medicated controls. First five groups were infected with Eimeria tenella sporulated oocysts @ 1,00,000/chick at the age of 20 days. Body weight gain, feed consumption, feed conversion ratio were investigated throughout the experimental period, and bloody diarrhea and oocysts excretions were investigated at the first and the second week after infection. Maximum coccidiostatic effect was observed with turmeric (3%) showing mild bloody diarrhea as compared to other infected groups receiving turmeric containing rations. This effect was comparable with a standard coccidiostat i.e., salinomycin sodium. Similarly, the weight gain in the groups treated with salinomycin sodium (2280g) and 3% turmeric (2293g) were also significantly higher (p < 0.05) than that of infected control group (1955g). In the groups treated with ration supplemented with 3% turmeric powder and salinomycin sodium, the peak excretion of oocysts was delayed about 1 or 2 days relative to the control infected group. Concentration-dependent coccidiostatic effect of turmeric suggested that further studies should be carried out to determine the possible maximum safe levels of turmeric with least toxic effects to be used as coccidiostat.
