| Abstract | ||
| This experiment was conducted to evaluate the impact of several levels of nano zinc into grower Japanese quail (Coturnix japonica) diet on feed efficiency, mortality rate, carcass traits, liver and kidney physiological function, histopathology of liver and spleen and economic efficiency. A total of 144 one-week-old quail chicks were randomly divided into four treatments. The control group (G1) received a standard corn–soybean diet containing 24% crude protein and 2900 kcal/kg. Groups G2, G3, and G4 were supplemented with 25, 50, and 100 mg nano zinc/kg diet, respectively. The results showed that dietary nano zinc had no significant effect on feed efficiency, carcass characteristics, or mortality rate. However, significant improvements in serum uric acid, AST, ALT, and creatinine values were observed in G3, followed by G2. Histopathological examination revealed structural alterations in liver tissue, particularly at the higher dose (100 mg/kg). Net revenue was low in all nano zinc treated groups compared to control. In conclusion, nano zinc with levels 25 and 50 mg / kg diet improved liver and kidney function tests but did not affect FE or carcass traits of grower Japanese quail. Nano zinc at high levels affects hepatic tissue and creates low economic efficiency. | ||
