| Abstract |
The present study was carried out to determine the effect of onion (Allium cepa) additives at 3 and 5glkg diet either in fresh and dried forms on growth performance, nutrients utilization, carcass composition and blood parameters of mono sex Nile tilapia (Oreochromis niloticus) fry with initial weight of 0.26 g. The treatments were performed for 22 weeks in triplicates concrete ponds sized 3m3 stocked with 60 Nile tilapia fry for each replicate. The obtained results indicated that incorporation of dried onion in the diets improved growth performance parameters, nutrients utilization, increased protein content of whole fish body and decreased its fat content. Some blood serum parameters were affected with addition of dried onion such as increased total protein, total albumin and total globulin. The increases in these parameters were more pronounced at higher incorporation levels either in fresh or dried form of onion compared to the unsupplemented diet. The reduction in gain costs in the onion added groups was more pronounced in groups fed on diet containing dried onion at "level of 5glkg. Based on results of the present study, addition of growing Nile tilapia diets with dried onion at 5glkg diet level is recommended to achieve better growth performance, feed utilization and to reduce the costs of production of one kg/gain in weight.
Keywords: Onion, Allium cepa, Nile tilapia, growth performance, nutrients utilization, carcass composition, blood parameters, costs
