Effect of Adding Different Levels of Silver -Curcumin Nanoparticles on Some Productive Traits, Blood Parameters and Antioxidant Status of Broiler Chickens

Abstract

The objective of the current study was to investigate the impact of adding different levels of silver-curcumin nanoparticles on some productive traits, blood parameters and antioxidant status of broiler chickens. A total of 144 broiler chicks (Ross308),one day old, with an average weight of 40 grams, were used in this study. The chicks were randomly distributed into four experimental treatments (each with 36 chicks), with three replicates for each treatment (12 chicks per replicate), using a completely randomized design for a period of 35 days. The first treatment was a control without addition, while the second, third, and fourth treatments, each added 1, 1.5, and 2 mg of silver-curcumin nanoparticles per liter of drinking water, respectively. The results indicated that the best average body weight, overall weight gain, and feed conversion efficiency were in the fourth treatment. The results indicated a significant increase (p≤0.05) in some blood parameters such as the packed cells volume , red blood cells, and hemoglobin concentration in the third and fourth treatments compared to the other experimental treatments. The results indicated a significant increase (p≤0.05) in the third and fourth treatments for the effectiveness of the GPX enzyme compared to the control and the second treatments. In terms of the CAT enzyme's efficiency, the results showed an improvement all treatments when compared to the control treatment. While the results did not indicate a significant difference in the mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), the activity of the enzyme superoxide dismutase (SOD), and the concentration of malondialdehyde (MDA) among the study treatments. It can be concluded that adding 2 mg/L of silver- curcumin nanoparticles has improved the growth of broilers and their feed conversion efficiency, as well as improving blood parameters and enhancing antioxidant enzymes such as glutathione peroxidase and catalase.
