Abstract | The current study was carried out to investigate the in-ovo effect of L-arginine on gross anatomy of tibial bone, alkaline phosphatase enzyme and growth parameters in Japanese quail (Coturnix japonica). For in-ovo inoculation, the eggs (n = 480) were equally divided into four groups (Group I: Control, 0% L-arginine; Group II: 1% L-arginine (1 g / 100 ml); Group III: 2% L-arginine (2 g / 100 ml), and Group IV: 3% L-arginine, (3 g / 100 ml)). After hatching, the chicks of all the groups were reared on the basal diet for four weeks. Gross anatomy of tibial bone in terms of bone weight, bone length, medullary canal diameter, diaphysis, and tibio-tarsal index as well as growth performance was statistically (p<0.05) higher in 3% L-arginine in-ovo inoculated group as compared to control. Alkaline phosphatase levels were also significantly (p<0.05) better with 3% L-arginine in-ovo inoculation as compared to control. In conclusion, 3% L-arginine in-ovo inoculation improves morphometry of tibial bone, alkaline phosphatase levels and growth performance in Japanese quail birds.
