Abstract The aim of this study was to evaluate the effects of dietary urea-treated pomegranate (Punica granatum L.) peel (UTPP) on growth performance, carcass attributes, blood biochemical indices, immunity, intestinal morphology, and meat quality of broiler chickens subjected to heat stress. The treatment with urea increased the gross energy and crude protein contents, while decreased the ash, calcium, phosphorous, neutral detergent fiber, acid detergent fiber, extractable polyphenols, total anthocyanins, condensed tannins, and hydrolyzable polyphenols contents of pomegranate peel. A total of 200 1-day-old male broiler chickens were randomly allocated to four groups; each group had 5 floor pens with 10 birds each. The broiler chickens were fed with the basal diet containing 0, 15, 30 or 50 g UTPP / kg diet from day 1, and exposed to a cyclic high temperature (37 ± 1 °C, 55 % relative humidity) for 6 h / day from day 29–42. Dietary UTPP increased body weight gain during the starter (linear (L), P = 0.001; quadratic (Q), P

饲喂尿素处理石榴皮的热应激肉鸡的生长性能、胴体和血液性状、免疫力、空肠形态和肉质

摘要 本研究旨在评价日粮尿素处理石榴皮（UTPP）对受试肉鸡生长性能、胴体属性、血液生化指标、免疫力、肠道形态和肉质的影响。到热应激。尿素处理提高了石榴皮的总能量和粗蛋白质含量，同时降低了石榴皮的灰分、钙、磷、中性洗涤纤维、酸性洗涤纤维、可提取多酚、总花青素、缩合单宁和可水解多酚的含量。200只1日龄雄性肉鸡随机分为四组；每组有 5 个地板笔，每笔 10 只鸟。肉鸡从第 1 天开始饲喂含有 0、15、30 或 50 g UTPP/kg 日粮的基础日粮，并暴露于循环高温（37 ± 1 °C，55 % 相对湿度）下，从第 29-42 天起持续 6 小时/天。饮食 UTPP 增加了起始期间的体重增加（线性 (L)，P = 0.001；二次 (Q)，P
