Effect of nano-material combination on various performance traits of Japanese quails.

Effect of combination of two nano-materials: Nano Germanium (NG) and Nano Selenium (NS) on Japanese quails was investigated. Five solutions(treatments) were prepared in such a way that: T2, T3, T4, T5 and T6 contained 10 & 5; 15 & 7.5; 20 & 10; 40 & 20 and 75 & 37.5 ppb of NG and NS (combined in each treatments) respectively while the solution: T1 (control) contained only distilled water. Respective solutions (@ 0.5ml/bird) were administered orally to birds daily for eight-weeks continuously. Highest egg production (hen-housed and hen-day) and best FCR (Kg feed per dozen eggs and Kg feed per Kg egg mass) was obtained in the T5, however, no significant difference in egg quality, carcass-traits and immune-competence could be observed between the control and treatments. It was inferred that oral administration of two combined nano-materials used in present study improved overall egg production in quails and the dose combination used in T5 was the best. Administration of the nano-combinations had no adverse effects on egg-quality, carcass-yield, slaughter traits and immune-competence.
