Evaluation of the role of green synthesis silver nanoparticles as adsorbents and protective agents for broilers tissue treated with aflatoxin

Abstract

Aflatoxin (AF) is the most crucial problem in the poultry industry, feed contaminants lead to toxicity. This study aims to evaluate the effects of synthetic silver nanoparticles mediated by plant extract on the histopathological alteration in broilers treated with AF. Forty-five chicks were divided randomly into three groups: the control group, the second group of chicks were treated with aflatoxin at a concentration of 70 part per million rations for 21 days, the third group of chicks was treated with AF 70 ppm, and silver nanoparticles 150 ppm. Aflatoxin concentration significantly declines in the ratio of the third group 1.86 ppm in comparison to the second group 1.91 ppm. Histopathological examination in the liver of broilers infected with aflatoxicosis revealed vascular disturbances involving congestion of the central vein, recent thrombus formation, and dilatation of sinusoid with the cell adaptation mainly hyperplasia of epithelial cells lining the bile duct, and this considers pathognomic lesion of aflatoxicosis and hepatic necrosis. The silver nanoparticles exhibit a tissue protective role against aflatoxin, improving the histopathological architecture. The I See an Inside method is a good tool for statistical histopathological analysis, which revealed significant elevation in the score of liver alteration in the second group in contrast to the third and first groups. The study concludes that silver nanoparticles can adsorbent the aflatoxin and reduce its deleterious toxic effect, and ISI is one of the vital techniques for detecting toxic effects in variable parts of the liver.
