|Title:||Livol (IHF-1000), a new herbal growth promoter in white prawn, Penaeus indicus (Crustacea)|
|Abstract:||Livol (IHF-1000), new herbal product has been found as a potent growth promoter to stimulate the growth of white prawn. Juveniles of P. indicus were fed with livol at four dosages viz; 1.0%, 1.5%, 2.0% and 2.5% through a fish meal based supplementary diet having 40% protein. All levels of Livol administration produced significantly (P < 0.01) higher growth than control but the diet containing 1% livol promoted maximum growth, high conversion efficiency and improved nutrient digestibility. Specific growth rate (SGR%) was also maximum in 1% livol. Digestive enzymes activity (amylase, protease and lipase) was higher in the midgut of prawns fed livol diets. RNA/DNA ratio in the muscle and hepatopancreas of prawn fed livol were higher than control. The total dry matter contents of the carcass increased in the livol treated prawn while lipid, carbohydrate, fiber and ash contents showed no significant variation. The study indicated that livol could be recommended as a safe growth promoter for enhancing shrimp growth and production.|
