Table 1_Effect of dietary fat source on the composition of the cecal microbiome in maturing broiler chicken.xlsx

Diet has been found to significantly influence gut microbiota throughout various life stages, and gut microbiota have been increasingly shown to influence host physiology, health, and behavior. This study uses 16S rRNA sequencing to examine the effects of six different fat-supplemented diets (canola oil, coconut oil, fish oil, flaxseed oil, lard, and olive oil) on broiler chicken cecal microbial composition and predicted function in comparison with a common and inexpensive fat source (poultry fat). Groups of broilers were fed each of these diets and then evaluated on day 41 and day 55 of age. For both 41- and 55-day samples, Firmicutes and Bacteroidetes phyla were the dominant bacteria in the ceca accounting for 99% of the microbial community. Across the 41- and 55-day samples, treatment time was associated with a stronger and more significant microbiota shift (p

饮食已被证实对贯穿生命各个阶段之肠道菌群产生显著影响，而肠道菌群亦日益显现出对宿主生理、健康及行为的影响。本研究采用16S rRNA测序技术，以探究六种不同脂肪补充饲料（菜籽油、椰子油、鱼油、亚麻籽油、猪油和橄榄油）对肉鸡盲肠微生物组成及其预测功能的效应，并与一种常见且廉价的脂肪来源（家禽脂肪）进行对比。将肉鸡分为不同组别，分别喂养上述饲料，并在鸡龄41天和55天时进行评估。对于41天和55天的样本，厚壁菌门和拟杆菌门是盲肠中占主导地位的细菌，构成了微生物群落的99%。在41天和55天的样本中，处理时间与微生物群落的显著变化（p值）呈正相关。
