Effect of different levels of copper nanoparticles and copper sulphate on performance, metabolism and blood biochemical profiles in broiler chicken

摘要: Summary A study was conducted to investigate the influence of copper administration in ovo chicken embryos and/or supplied drinking water growing chickens form nanoparticles (Cu-NP) or sulphate (CuSO4). The fertilised eggs were assigned three groups (n = 50 per group): control (not injected), injected with 50 mg/kg Cu-NP CuSO4 at day 1 incubation. Thereafter, 126 one-day-old broiler randomly seven post-hatched groups: not and provided Cu water, Cu-NP + 20 mg/kg injected + 20 mg/kg CuSO4 + 20 mg/kg CuSO4. experiment carried out from 35 post-hatching. injection improved final body weight, average daily gain feed conversion ratio relation group. Conversely, provision had less an effect on growth performance comparison groups.
