Investigating the Effect of In Ovo Injection of Silver Nanoparticles on Fat Uptake and Development in Broiler and Layer Hatchlings

Table 1

Total oxygen consumption (O₂), carbon dioxide production (CO₂), and heat production (HP) of layer (Lohmann-Lo) and broiler (Ross-Ro) hatchlings in ovo injected with different concentrations of AgNano (50, 75, and 100 mg/kg) and the control (no-injection, C) measured at embryonic days 13 to 19¹.
