Therefore, this study aimed to investigate the influence of high\u2010energy diets (HED) on obesity and oxidative stress in domestic pigeons. Forty\u2010five adult clinically healthy\u2010domestic male pigeons were randomly assigned to three equal dietary groups including low (2,850\u00a0kcal\/kg), medium (3,150\u00a0kcal\/kg) and high (3,450\u00a0kcal\/kg) energy diets (named low energy diet, medium\u2010energy diet and HED, respectively). All birds received formulated diets for 60 consecutive days. Several parameters such as feed intake, body weight (BW), average weight gain (AWG) and total weight gain were determined. Serum concentrations of triglyceride (TG), total cholesterol (TC), high\u2010, low\u2010 and very\u2010low\u2010density lipoprotein cholesterols, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were evaluated at days 0, 30 and 60; and serum levels of total antioxidant capacity (T\u2010AOC), malondialdehyde (MDA) and cortisol were also measured at day 60. On day 60, five pigeons from each group were randomly euthanized and some parameters such as weight and relative weight of liver, breast muscle, and abdominal fat were determined. Furthermore, hepatic total fat content was also evaluated. BW, AWG, total weight, and circulating TG, TC, ALT, AST, ALP, MDA and cortisol in HED were significantly higher than other groups. Serum T\u2010AOC in HED was significantly lower than the other groups. In conclusion, this study showed that increasing dietary energy up to 3,450\u00a0kcal\/kg in pigeons led to obesity and oxidative stress in them. Accordingly, it could be stated that HED and obesity induce oxidative stress in pigeon and controlling the dietary energy intake of pigeons is necessary to prevent oxidative stress in them.<\/jats:p>","DOI":"10.1002\/vms3.478","type":"journal-article","created":{"date-parts":[[2021,4,3]],"date-time":"2021-04-03T07:59:31Z","timestamp":1617436771000},"page":"1391-1399","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Impact
