Application of Different Levels of Silver Nanoparticles in Food on the Performance and Some Blood Parameters of Broiler Chickens

This study was carried out on 240 broiler chickens in a completely randomized design in four treatments at 0, 300, 600 and 900 pmm levels of silver nanoparticles with four repetitions within 16 separate cages. The chickens were individually weighed and recorded at the end of every week of experiment. Increase in the amount of food intake and weight, was recorded every week and finally the food conversion ratio (FCR) was calculated; Also blood sampling was carried out to determine blood cells and parameters such as, WBC and some blood Enzymes (ALP, ALT and AST). The effect of different levels of silver nanoparticles had not significant on the number of white blood cells (WBC) and no significant on the blood enzymes at different levels. The effect of the treatment of 900 ppm of nanoparticle has more significant than the others on the weight of living chickens and also there was a significant difference in the food conversion ratio among all treatments at p<0.05. Finally the amount of FCR in 900 ppm showed lesser effect than other treatments.
