摘要： Tetramethylthiuram disulfide (thiram) is a pesticide and fungicide, widely used in agriculture, and is a recognized cause of tibial dyschondroplasia (TD), a skeletal abnormality in fast-growing broiler chickens. This study aimed to investigate the effect of resveratrol (RSV) against TD induced by thiram in broilers. A total of 240 broilers were evenly divided into three groups (n = 80) i.e., Control, TD and RSV. All groups received feed and water ad libitum, whereas the TD and RSV groups received standard diet with an addition of thiram (50 mg/kg of feed) from 4-7 days to induce TD. After the cessation of thiram on day 8, the RSV group was administered RSV at 400 mg/kg body weight orally from 8-18 days. Histopathological changes in tibia were assessed using hematoxylin and eosin (H&E) staining. In addition, the mRNA and protein expressions of targeted genes were analyzed using RT-qPCR, immunohistochemistry, and western blotting. Thiram feeding resulted in an increased growth plate (GP) width, decreased vascularization, irregular shaped chondrocytes with pyknotic nuclei, lameness, poor production performance, reduced levels of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), total antioxidant capacity (T-AOC), alkaline phosphatase (ALP) and elevated levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and malondialdehyde (MDA). The mRNA and protein expressions of BMP-2 and RUNX-2 were downregulated, whereas HIF-1 alpha was upregulated in TD affected broilers (p < 0.05). RSV administration resulted in a significant increase in mRNA and protein levels of BMP-2 and RUNX-2 (p < 0.05) and a decrease in the levels of HIF-1 alpha. In addition, RSV improved vascularization, angiogenesis, alleviated lameness, and enhanced production efficiency. Furthermore, it restored the GP width, serum biochemical levels and liver antioxidant enzymes. In conclusion, this study indicated that resveratrol mitigated the adverse effects of thiram toxicity in broiler chickens.
