Additives with bioactive properties can improve chickens’ gut health. This study investigated the physiological status of the gut, including its morphological structure and microbiome activities in chickens fed diets supplemented with phytogenic ingredients with hops (Anta®Phyt) or a mixture of a free butyrate acidifier and gluconic acid (PreAcid). In this study, 1155 broilers were distributed to three dietary treatments with 5 replicate pens per treatment, 77 birds each. Anta®Phyt was added at 400/300/200/200 mg/kg diet whereas PreAcid was added at 3/2/1/1 g/kg starter/grower I/grower II/finisher diet respectively. Dietary treatments did not compromise body weight in different growth periods. In the birds fed PreAcid-supplemented diet, higher gut concentration of butyric acid was observed, particularly in the early stage of growth, while the profile of the short-chain fatty acids was maintained among the treatments. Neither additive significantly affected cecal bacterial enzyme activities. Feeding the birds with Anta®Phyt and PreAcid had beneficial effects on gut morphostructure indices, including intestinal wall thickness, crypt depth and the villus height to crypt depth ratio, in 35- and 42-day old birds. In conclusion, the feeding Anta®Phyt- or PreAcid-supplemented diet exerted beneficial effects on the indices determining the physiological status of the gut and maintained good performance of birds of different ages.

日粮与啤酒花和游离丁酸酸化剂与葡萄糖酸的混合,可维持鸡肠道健康状况和生产性能。

具有生物活性的添加剂可以改善鸡的肠道健康。本研究调查肠道的生理状态,包括其形态结构和在供给补充有植物性成分与啤酒花(安塔日粮的鸡微生物活动® PHYT)或游离丁酸酸化剂的混合物和葡萄糖酸(预酸)。在这项研究中,将1155只肉鸡分配到三种饮食处理中,每种处理使用5支重复笔,每只处理77只鸡。安踏®分别以400/300/200/200 mg / kg的日粮添加Phyt,而分别以3/2/1/1 g / kg的起子/种植者I /种植者II /完成者饮食添加PreAcid。饮食疗法不会在不同的生长期影响体重。在饲喂添加了PreAcid的饲料的家禽中,可观察到较高的丁酸肠浓度,尤其是在生长的早期,而短链脂肪酸的分布在各处理中均保持不变。两种添加剂均未显着影响盲肠细菌酶活性。饲喂安塔鸟® PHYT和预酸对肠道形态结构指数的有益效果,包括肠壁厚,隐窝深度和绒毛高度到隐窝深度比,在35-和42天龄的鸟类。总之,喂养安踏®补充Phyt或PreAcid的饮食对确定肠道生理状态的指标产生了有益的影响,并保持了不同年龄的禽类的良好性能。
