This study investigated the effects of different supplementation ways of lycopene during pre-hatch (from the diet of hens) and post-hatch (from the diet of progeny) on production performance, antioxidant capacity and biochemical parameters in chicks. In total, 360 hens were fed diets supplemented with 0 (control group) or 40 mg lycopene/kg diet. From 28 to 34 days after the start of supplementation (30 weeks old), 650 qualified eggs were collected to artificial incubation. In this trial, 2 × 2 factorial designs were used. Male chicks hatched from hens fed with 0 or 40 mg lycopene/kg diet were fed a diet containing either 0 or 40 mg lycopene/kg diet. The results showed that, relative to control, in ovo-deposited lycopene significantly increased chick birth body weight, improved liver total antioxidant capacity (T-AOC), glutathione peroxidase (GSH-Px) and glutathione to oxidized glutathione ratio (GSH: GSSG), and significantly declined liver malondialdehyde (MDA) level and increased liver lycopene content during 0-14 days after hatching. On days 14 after hatching, dietary lycopene in diet began to take over gradually. Both supplementation ways of lycopene increased immune organ index, serum high-density lipoprotein (HDL) cholesterol, villus length and villus/crypt in duodenum, jejunum and ileum. Data in this study suggested lycopene supplementation could improve antioxidant capacity and immune function, and regulate lipid metabolism in chicks.
本研究探讨了在孵化前（来自母鸡的饮食）和孵化后（来自后代的饮食）不同补充番茄红素的方式对小鸡生产性能、抗氧化能力和生化参数的影响。总共 360 只母鸡喂食添加 0（对照组）或 40mg 番茄红素/kg 日粮的日粮。从开始补充后的 28 到 34 天（30 周龄），收集了 650 个合格的鸡蛋进行人工孵化。在这项试验中，使用了 2×2 析因设计。喂食 0 或 40mg 番茄红素/kg 日粮的母鸡孵化的雄性小鸡喂食含有 0 或 40mg 番茄红素/kg 日粮的日粮。结果表明，与对照组相比，胎盘中沉积的番茄红素显著增加了雏鸡的初生体重，提高了肝脏总抗氧化能力（T-AOC）、谷胱甘肽过氧化物酶（GSH-Px）和谷胱甘肽与氧化谷胱甘肽的比值（GSH:GSSG），显著降低了肝脏丙二醛（MDA）水平，并在孵化后 0-14 天内增加了肝脏番茄红素含量。在孵化后 14 天，日粮中的番茄红素开始逐渐替代。两种补充番茄红素的方式都增加了免疫器官指数、血清高密度脂蛋白（HDL）胆固醇、十二指肠、空肠和回肠的绒毛长度和绒毛/隐窝比。本研究的数据表明，番茄红素补充剂可以提高小鸡的抗氧化能力和免疫功能，调节脂质代谢。
