The effect of garlic powder (Allium sativum) on growth indices and survival rate of English name Litopenaeus vannamei (Boone, 1931)

Garlic plant due to organophosphorus compounds can be used as growth promoters and immune system of shrimp. In this study the effect of diets containing 0, 0.5, 1 and 2% powder of garlic (Allium sativum) were evaluated on the weight rate, length rate, specific growth rate (SGR), feed conservation rate (FCR), feed conversion efficiency (FCE) and survival rate of Litopenaeus vannamei with weight average 8.64 gr for 60 days. The results indicated weight, length average and SGR of shrimp fed diet 2% (15.42 g, 16.2 cm and 237.368 %, respectively) were significantly higher than other treatment (P0.05). Also, FCE of shrimp fed diet 2 % was significantly increased and FCR of them were significantly lower than other treatments (P
