摘要
本实验的目的是研究各种纤维来源如何影响日本鹌鹑的性能、微生物数量和肠道组织学,实验采用完全随机设计,为期 42 天。日粮处理包括不含纤维的玉米-豆粕型日粮(对照组,CTL),以及添加了向日葵壳(SFH)和甜菜浆(SBP)(20 和 40 g kg-1)的 CTL。每周记录体重增加(BWG)和采食量(FI)。42日龄时测量胴体特征、盲肠微生物群、血液变量和肠道组织学。添加 40 g kg-1 的 SBP 可显著降低体重增加,并提高 1 到 21 天的饲料转化率(P < 0.05)。摄入 SFH 的家禽胃肠道和胗的相对重量显著增加。日粮中添加纤维后,血液中的甘油三酯浓度降低。然而,与饲喂 SFH 的禽类相比,饲喂 SBP(20 和 40 g kg-1)的禽类血液中胆固醇浓度明显增加(P < 0.05)。与饲喂 20 和 40 g kg-1 SFH 的禽类相比,饲喂 4 g kg-1 SBP 的禽类盲肠中的大肠杆菌数量明显增加(P < 0.05)。与其他处理相比,饲喂 20 g kg-1 和 40 g kg-1 SFH 的禽类空肠绒毛高度明显增加(P < 0.05)。总之,研究结果表明,在日粮中添加 40 g kg-1 的 SBP 对家禽的生产性能和其他生理参数有负面影响。然而,使用 SFH 和 20 g kg-1 SBP 产生的结果与 CTL 中的鸟类相似,在某些情况下甚至更好。
Changes in performance, cecal microflora counts and intestinal histology of Japanese quails fed diets containing different fibre sources
The purpose of this experiment was to investigate how various fiber sources impact the performance, microbial population, and intestinal histology of Japanese quail that was performed in a completely randomized design for 42 days. The dietary treatments involved a fiber-free corn-soybean meal-based diet (control, CTL), and CTL with added levels of sunflower hulls (SFH) and sugar beet pulp (SBP) (20 and 40 g kg-1). Body weight gain (BWG) and feed intake (FI) were recorded weekly. Carcass characteristics, cecal microbial population, blood variables and intestinal histology were measured on the 42 day of age. Adding 40 g kg-1 of SBP led to a significant decrease in body weight gain and an increase in the feed conversion ratio of birds from 1 to 21 days (P < 0.05). The relative weight of the gastrointestinal tract and gizzard increased significantly in birds that consumed SFH. Blood triglyceride concentration decreased with the inclusion of fiber in the diet. However, there was a notable increase in blood cholesterol concentration in the birds that were fed SBP (20 and 40 g kg-1) in comparison to those fed SFH (P < 0.05). The population of E. Coli in the cecum increased significantly in the birds that were fed 4 g kg-1 of SBP as opposed to those fed 20 and 40 g kg-1 of SFH (P < 0.05). The villus height of the jejunum in birds that were fed 20 g kg-1 and 40 g kg-1 of SFH demonstrated a significant increase in comparison to the other treatments (P < 0.05). In general, the findings of this research indicated that the inclusion of 40 g kg-1 of SBP in the diet had a negative impact on performance and other physiological parameters. However, the use of SFH and 20 g kg-1 of SBP yielded similar results to birds in the CTL, and in some cases, even better outcomes.
