为研究干姜对肉鸡小肠绒毛组织学和生长性能的影响，将64只马歇尔肉仔鸡随机分为4组，每组4个重复，每个重复4只鸡。在基础市售糖化饲料中添加0（对照）、5、10和20 g/kg DFG，连续饲喂42天。随着日粮中DFG水平的增加，采食量呈下降趋势，20 g/kg DFG组显著降低（p < 0.05）。所有DFG组中的体重增加均较高，其中10 g/kg DFG组中的体重增加最高（p < 0.05），导致所有DFG组中的饲料效率提高。各剂量组小肠绒毛高度、绒毛面积、细胞面积及细胞有丝分裂数均高于对照组。各实验组小肠绒毛和细胞均出现突起和细胞团，提示小肠绒毛和细胞可能肥大。本研究结果表明，日粮DFG可以作为天然饲料添加剂，诱导肉鸡的生长性能，作为一个结果，刺激形态成熟，从而肠道功能。
To evaluate the effect of dietary dried fermented ginger (DFG) on intestinal villous histological alteration and growth performance, 64 Marshall Chunky male broilers were divided into four groups, each with four replicates of four chickens. Birds were fed the basal commercial mash diet supplemented with DFG at 0 (control), 5, 10 and 20 g/kg for 42 days. With increasing dietary DFG levels, feed intake tended to decrease and significantly decreased in the 20 g/kg DFG group (p < 0.05). Weight gain was higher in all the DFG groups, with the highest in the 10 g/kg DFG group (p < 0.05), resulting in an improved feed efficiency in all the DFG groups. Intestinal villus height, villus area, cell area and cell mitosis in all the intestinal segments were higher in all the DFG groups than in the control group. Protuberated cells and cell clusters were found in all the DFG groups, suggesting that the intestinal villi and cells might be hypertrophied. The present results indicate that dietary DFG can be used as a natural feed additive to induce broiler growth performance as a result of stimulation of morphological maturation and in consequence intestinal function.
