The present work, studied the effect of 0, 1,000, 1,500 and 2,000 mg of garlic powder/kg dry ration for Piaractus mesopotamicus (Osteichthyes: Characidae), weighting 73.6 ± 39.4 g and measuring 15.0 ± 2.7 cm, fed for a period of 15, 30 and 45 days. Fifteen days after treatment with 1,000 and 2,000 mg of garlic/kg dry ration, significant reduction of Anacanthorus penilabiatus (Monogenea: Dactylogyridae) in the gills was related. Nevertheless, the addition of garlic to the ration caused significant increase in the erythrocyte number and in the thrombocyte percentage in the circulating blood. However, a decrease in the lymphocyte percentage was also observed. After 45 days, fish fed with garlic showed significant increase in the erythrocyte number, leucocyte, haemoglobin rate, hematocrit and thrombocyte.
Résumé
Ce travail a étudié l'effet de 0, 1 000, 1 500 et 2000 mg d'ail en poudre par kg de ration sèche sur Piaractus mesopotamicus (Osteichthyes : Characidae), pesant 73,6 ± 39,4 g et mesurant 15,0 ± 2,7 cm, alimenté pendant une période de 15, 30 et 45 jours. Après 15 jours d'alimentation avec 1 000 et 2000 mg d'ail, une diminution significative du nombre d'Anacanthorus penilabiatus (Monogenea : Dactylogyridae) sur les branchies a été observée. L'addition de l'extrait d'ail dans la ration alimentaire a provoqué une augmentation significative du nombre d'érythrocytes et de thrombocytes dans le sang du poisson. Toutefois, une diminution des lymphocytes a été aussi observée. Après 45 jours de traitement, le poisson alimenté avec ail a montré une augmentation significative des taux d'erythrocytes, de leucocytes, de thrombocytes et d'hémoglobine.
