Abstract: 

The technology of green synthesis of nano-metals is considered promising, as it produces environmentally friendly nano-metals in larger quantities and can be used at low levels in broiler diets, which reduces the amount excreted in the bedding and thus reduces environmental pollution. This experiment was conducted in the farm of Al-Anwar Poultry Company in Al-Anwar Governorate. Babel, for a period of 35 days from 11/28/2022 to 1/2/2023, during which the physiological and productive response to adding copper nanoparticles and copper nanoparticles loaded on papaya plants to the diet of broilers under conditions of environmental stress (heat stress) was studied. I used 360 unsexed broiler chickens (Ross-308), and the experimental chickens were prepared from the Al-Anwar Company hatchery in Babil Governorate. The chickens were raised on the floor in cages (pens) with 18 cages, dimensions of 1.5 x 1 m², and the floor was covered with sabus with a thickness of 4-5 cm. In addition to the paper brush. The experimental treatments included (0, 8, and 16 mg/kg of Cu and NPs, 8 and 16 mg/kg of Cu loaded on papaya plants, and 10 mg/kg of papaya feed, for treatments (T1, T2, T3, T4, T5, and T6, respectively. All experimental treatments were exposed to a temperature of (34±1°C) in all study periods. The results showed a significant superiority of the T5 treatment in the concentration of glutathione peroxidase, and a significant improvement in the MDA (Malondialdehyde) concentration in favor of the T5 and T6 treatments. It was also shown that there was a significant improvement in the concentration of the enzyme AST (Aspartate aminotransferase), glucose, and heat shock protein in the blood of the birds of treatment T4 and T5. It appeared that the activity of the enzyme SOD (Superoxide dismutase) and immunoglobulin IgM in treatment T5 and ALP (Alkaline phosphatase) and immunoglobulin IgG and protein increased significantly. In treatment T4, respectively, there was a significant improvement in uric acid concentration in favor of treatments T2, T3, T4, and T5 compared to the rest of the treatments. All addition treatments also significantly improved the level of cholesterol compared to the control treatment, and the concentration of IgA increased significantly for treatments T3, T4, and T5. There was a significant increase in the relative weight of the Fabricia pouch and Fabricia guide in the T2 treatment birds.
