摘要

1.本研究的目的是确定不同粒径的豆壳对黄羽肉鸡生长性能、血液指数和肠道微生物群的影响。 2. 将 240 只健康、一天龄的黄羽肉鸡随机分为 4 组,每组 6 个重复,每栏 10 只。对照组饲喂基础日粮(对照组)。对于处理组,在基础日粮中添加不同粒径的 5%豆壳。三个处理组的豆壳粒径几何平均直径(dgw)分别为 299.69 μm(LowPS)、489.85 μm(MediumPS)和 734.83 μm(HighPS),几何标准偏差(Sgw)分别为 1.75 μm、1.62 μm 和 1.67 μm。 结果表明,四个处理组的生长性能变量和器官指数没有差异。中PS组的TG、T-CHO、ALT、HDL-C和GSH-PX水平升高,T-AOC水平降低,而低PS组和高PS组的HDL-C和GSH-PX水平升高(p 固着菌和类杆菌)。加入不同粒径的 5%大豆壳对盲肠微生物群的α多样性指数没有影响。与低粒径组和中粒径组相比,高粒径组的固着菌属相对丰度明显较高,而拟杆菌属相对丰度较低,但与对照组相比没有差异。蓝藻属的相对丰度在高浓度多糖组明显高于其他三组。4. 总体而言,添加不同粒径的豆壳对黄羽肉鸡的生长性能、血液指数和盲肠微生物群组成的影响有限。

Effects of soyhulls with different particle size on the growth performance, blood indices and gut microbiota of yellow feather broilers.

1. The objective of this study was to determine the effects of soyhulls with different particle sizes on the growth performance, blood indices and gut microbiota of yellow feather broilers.2. Total of 240 healthy, one-day-old, yellow feather broilers were randomly divided into four groups, with six pen replicates within each group and ten birds per pen. The control group birds were fed the basal diet (Control). For the treatment groups, 5% soyhulls with different particle sizes were included in the basal diet. The particle size geometric mean diameters (dgw) of the soyhulls in the three treatment groups were 299.69 μm (LowPS), 489.85 μm (MediumPS) and 734.83 μm (HighPS) with geometric standard deviation (Sgw) 1.75 μm, 1.62 μm and 1.67 μm, respectively.3. Results showed that the growth performance variables and organ indices were not different among the four groups. The MediumPS group had increased TG, T-CHO, ALT, HDL-C, and GSH-PX levels and decreased T-AOC levels, whereas LowPS and HighPS groups had increased HDL-C and GSH-PX levels (p < 0.05). Microbial diversity analysis showed that the intestinal microbiota of yellow feather broilers mainly included Firmicutes and Bacteroidetes. Inclusion of 5% soyhulls with different particle size had no effect on alpha diversity indices of caecal microbiota. The HighPS group had significantly higher relative abundance of Firmicutes spp. and lower Bacteroidetes spp. compared with the LowPS and MediumPS group but this was not different from the Control group. The relative abundance of Cyanobacteria spp. was significantly higher in the HighPS group than the other three groups. LEfSe analysis showed that there were more enriched biomarker taxa in the groups with soyhulls than the control group.4. Overall, the inclusion of soyhulls with different particle sizes had limited effects on growth performance, blood indices and caecal microbiota composition of yellow feather broilers.

期刊介绍: From its first volume in 1960, British Poultry Science has been a leading international journal for poultry scientists and advisers to the poultry industry throughout the world. Over 60% of the independently refereed papers published originate outside the UK. Most typically they report the results of biological studies with an experimental approach which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: anatomy, embryology, biochemistry, biophysics, physiology, reproduction and genetics, behaviour, microbiology, endocrinology, nutrition, environmental science, food science, feeding stuffs and feeding, management and housing welfare, breeding, hatching, poultry meat and egg yields and quality.Papers that adopt a modelling approach or describe the scientific background to new equipment or apparatus directly relevant to the industry are also published. The journal also features rapid publication of Short Communications. Summaries of papers presented at the Spring Meeting of the UK Branch of the WPSA are published in British Poultry Abstracts .
