Effect of dietary onion (Allium cepa L.) powder on growth performance, survival rate and feed efficiency of Goldfish (Carassius auratus)
2015
This study investigated the Onion Powder (OP) supplementation in the diet of the Gold fish (Carassius auratus) on the growth survival rate and feed efficiency that were carried out in eight weeks experimental period. Fish averaging 1.16 ± 0.09 g were randomly stocked into aquarium. Four experimental diets were prepared to contain onion powder at the concentrations of 0, 0.5, 1 and 1.5% for diets. In order to adapted to experimental condition. The optimal growth performance and feed efficiency were observed in fish fed the 0.5% onion powder diet. The highest survival rate in fish fed the 0.5% onion powder diet compared with the control (P<0.05). In conclusion, it can be suggested that dietary inclusion of 0.5% onion powder could be effective at improving growth and feed efficiency of Goldfish.
