Effects of allicin extract from garlic supplement in feed for growth and survival rate of Thailand Frogs (Rana tigerina Bubois, 1981) seed stage

Abstract

    This study aims to determine the appropriate concentration of allicin added to food on growth and survival rate of Thai frog breeds. Frogs were raised in hapas with a volume of 0.7 m × 0.7 m × 0.9 m, 10-day-old froglets (tadpoles) were arranged in the experiment at a density of 600 frogs/m². The experiment consisted of 4 treatments with different allicin concentrations (0 g/kg of feed (DC), 1 g/kg of feed (NT1), 2 g/kg of feed (NT2), 3 g/kg of feed (NT3) and the food containing allicin was fed for 2 days (twice/day) and then stopped for 5 days. After 42 days of culture, the weight growth of Thai frog breeds was the highest in the treatment with 2 g allicin/kg of food (Wf = 2.41 g, WG = 2.37 g, DWG = 0.06 g/day). The highest (87.33 %) and lowest (67.78 %) survival rates of Thai frog breeds were obtained in the treatment with 2 g allicin/kg of food and in the control treatment with 0 g allicin/kg of food, respectively. Statistically significant difference was shown between treatments (p < 0.05). Experimental results show that when raising Thai frogs, allicin can be added to the feed at a concentration of 2 g/kg of feed for the highest growth and survival rate.
