Effect of Olive Leaves and Propolis Extracts on Growth Performance, Immunological Parameters and Economic Efficiency using Nile Tilapia (Oreochromis niloticus)
Abstract:This study aimed to evaluate the effects of olive leaves ether extract (EEOL) and ethanol extract of propolis (EEP) on growth performance, body composition, nutrient digestibility, immunological parameters and economic efficiency in Nile tilapia, Oreochromis niloticus. Three Isonitrogenous (crude protein 35%), isocaloric (Digestable energy, 2900kcal) diets were fed to Nile tilapia averaging 19.7 ±0.94 g. A basal control diet had no additives, second and third diets containing 0.1% EEOL (1g/kg) and 0.4% EEP (4 … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
