บทคัดย่อ: According to the strong anti-coccidial property against Eimeria tenella of fingerroot oil from our in vitro study, two experiments were designed to study the bio-efficiency of fingerroot oil against coccidiosis in broilers. The optimum concentration as anti-coccidial agent was investigated in the first experiment. Sixty thirteen days old broilers were assigned into six groups as following; non-challenged with E. tenella group and fed basal diet without anti-coccidial drug (gr. 1), whereas gr. 2 to 6 were groups challenged with E. tenella and fed basal diets without anti-coccidial drug, supplemented with 60 ppm salinomycin, 89, 178 and 356 ppm fingerroot oil, respectively. All broilers were orally inoculated with 6x104 sporulated oocysts at 14 days old and sacrificed at day 7 post-inoculation. Results revealed that challenged group without dietary anti-coccidial drug showed the highest lesion score, whereas caecal lesion scores of challenged broilers were decreased with increasing doses of fingerroot oil and at 356 ppm fingerroot oil provided the non-significantly response compared with using 60 ppm salinomycin. Thus, fingerroot oil at 356 ppm was used as dietary coccidiostat agent compared with 60 ppm salinomycin and its effects on productive performance as well as the toxicity were further studied in experiment 2. Two hundred and seventy one day old broilers were divided into three groups and were randomly fed one of these diets as following; basal diets without anti-coccidial drug, with 60 ppm salinomycin and 356 ppm fingerroot oil. During the feeding period of 35 days, diet and water were administered ad libitum. Productive performance of broilers during starter period was not improved by supplementation either salinomycin or fingerroot oil. However, the feed intake of broiler fed diet supplemented with fingerroot oil in grower period was higher than the non-supplemented group (P < 0.05). Prolonged administration of fingerroot oil for 35 days did not have a detrimental effect on the liver and kidney tissues by providing the similar values of serum AST and creatinine concentration. Therefore, fingerroot oil can be an effective and safe natural alternative for coccidiostatic drug in broiler production.
