| Abstract | ||
| This study investigated the effect of a lemon, onion, and garlic (LOG) juice mixture on the Nile tilapia health and productivity including; growth performance, feed utilization, body composition, immune status and gene expression of IGF-1, IGF-2, and GH genes. 120 fish were randomly distributed among 12 tanks into four groups before fed with different iso-nitrogenous and iso-caloric diets, containing 0%, 0.5%, 1.0%, or 1.5% of LOG juice for 56 days. The results revealed significant improvements in growth performance, especially specific growth rate in all LOG groups compared to the control. Moreover, a significant increase has been recorded in crude protein percentages in fish body composition. Energy retention (ER)% and protein productive value (PPV)% displayed substantial increases in all experimental groups. Moreover, AST and cholesterol levels were significantly higher in the 1.5% LOG group than the other groups. Immune parameters including lysozyme activity, antiprotease activity and total protein increased in 0.5% LOG and 1% LOG groups compared to the control. Furthermore, the dietary interventions led to a significant up-regulation of growth-related genes expression, compared to the control group, especially for IGF-1 and GH. This study demonstrates the efficacy of the bioactive mixture (LOG) in improving the Nile tilapia health; growth performance, and growth-related gene expressions and immunity. The study results recommended using LOG as a growth promoter, especially with a dose of 1.5% LOG. | ||
