摘要

基于宏基因组学和代谢组学技术,研究了蛋鸡饲粮中添加紫草多糖(CPs)对蛋黄氧化稳定性和脂肪酸组成的影响。饲粮中添加cp可提高鲜蛋和贮藏蛋中总酚含量。1.0% cp组贮藏卵的超氧化物歧化酶活性升高,丙二醛含量降低。饲粮中添加1.0% CPs可提高贮藏蛋黄中多不饱和脂肪酸(PUFA)的含量,包括二homo-γ-亚麻酸(C20:3n6)、花生四烯酸(C20:4n6)和二十二碳六烯酸(C22:6n3)。在1.0%的cp组中,盲肠中甲烷预菌、拟杆菌和Merdibacter的丰度增加。CPs使盲肠中褪黑素含量升高,棕榈酸和肉豆蔻酸含量降低。综上所述,CPs可以提高蛋黄的抗氧化能力和脂肪酸组成。

Integrated metagenomics and metabolomic to reveal the effects of dietary comfrey polysaccharides on the oxidative stability and fatty acid composition of egg yolks in laying hens
This study investigated the influences of comfrey (Symphytum officinale L.) polysaccharides (CPs) in the diet of laying hens on the oxidation stability and fatty acid composition of the egg yolks based on metagenomic and metabolomics techniques. Dietary CPs improved the total phenolic content in fresh and stored eggs. The activity of superoxide dismutase was increased, and the content of malondialdehyde was reduced in the stored eggs of the 1.0 % group of CPs. Dietary supplementation with 1.0 % CPs increased some polyunsaturated fatty acid (PUFA) contents in stored egg yolk, including dihomo-γ-linolenic acid (C20:3n6), arachidonic acid (C20:4n6), and docosahexaenoic acid (C22:6n3). The abundances of Methanobrevibacter, Parabacteroides, and Merdibacter in the caecum were increased in the 1.0 % group of CPs. The content of melatonin was increased, and the contents of palmitic acid and myristic acid in the caecum were decreased by CPs. These results suggested that CPs could improve the antioxidant status and fatty acid composition of egg yolks.

期刊介绍: First self-published in 1921, Poultry Science is an internationally renowned monthly journal, known as the authoritative source for a broad range of poultry information and high-caliber research. The journal plays a pivotal role in the dissemination of preeminent poultry-related knowledge across all disciplines. As of January 2020, Poultry Science will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers. An international journal, Poultry Science publishes original papers, research notes, symposium papers, and reviews of basic science as applied to poultry. This authoritative source of poultry information is consistently ranked by ISI Impact Factor as one of the top 10 agriculture, dairy and animal science journals to deliver high-caliber research. Currently it is the highest-ranked (by Impact Factor and Eigenfactor) journal dedicated to publishing poultry research. Subject areas include breeding, genetics, education, production, management, environment, health, behavior, welfare, immunology, molecular biology, metabolism, nutrition, physiology, reproduction, processing, and products.
