Journal ArticleDOI
Alteration of the Antioxidant Capacity and Gut Microbiota under High Levels of Molybdenum and Green Tea Polyphenols in Laying Hens.
Jianping Wang,Zengqiao Yang,Pietro Celi,Lei Yan,Xuemei Ding,Shiping Bai,Qiufeng Zeng,Xiangbing Mao,Bing Feng,Shengyu Xu,Keying Zhang +10 more
TL;DR: Microbiota analysis revealed differentially enriched microbial compositions in the cecum caused by MO and TP, which might be responsible for the protective effect of dietary TP during a MO challenge.
Journal ArticleDOI
Effect of dietary 25-hydroxycholecalciferol supplementation and high stocking density on performance, egg quality, and tibia quality in laying hens.
Jianping Wang,Lingyun Qiu,Haojie Gong,Pietro Celi,Lei Yan,Xuemei Ding,Shiping Bai,Qiufeng Zeng,Xiangbing Mao,Shengyu Xu,Caimei Wu,Keying Zhang +11 more
TL;DR: High stocking density is indicated to result in reducing production performance, shell color and quality, and tibia health, whereas dietary 25-OH-D3 was able to maintain tibiahealth and to mitigate the negative impact of high stocking density on productive performance.
Journal ArticleDOI
Effect of benzoic acid on production performance, egg quality, intestinal morphology, and cecal microbial community of laying hens.
Haojie Gong,Zengqiao Yang,Pietro Celi,Lei Yan,Xuemei Ding,Shiping Bai,Qiufeng Zeng,Shengyu Xu,Zhuowei Su,Yong Zhuo,Keying Zhang,Jianping Wang +11 more
TL;DR: Dietary supplementation with benzoic acid positively modulated intestinal health by improving intestinal morphology and enriching microbial composition and significantly improved egg quality.
Journal ArticleDOI
The impact of dietary supplementation of different feed additives on performances of broiler breeders characterized by different egg-laying rate.
Shuju Zhao,Keying Zhang,Xuemei Ding,Pietro Celi,Lei Yan,Shiping Bai,Qiufeng Zeng,Xiangbing Mao,Shengyu Xu,Jianping Wang +9 more
TL;DR: Overall, the results gathered in this study indicate that LR breeders have lower production performance, eggshell thickness and decreased gastrointestinal tract functionality in compared with the AR breeders.
Journal ArticleDOI
Dietary 25-hydroxyvitamin D improves intestinal health and microbiota of laying hens under high stocking density.
Jianping Wang,Chunhua Zhang,Tao Zhang,Lei Yan,Lingyun Qiu,Huadong Yin,Xuemei Ding,Shiping Bai,Qiufeng Zeng,Xiangbing Mao,Keying Zhang,Caimei Wu,Yue Xuan,Zhiguo Shan +13 more
TL;DR: It is suggested that supplementing 25-OH-D3 in diets may elevate gut health through the improvement of intestinal barrier function, antioxidant capacity and cecal microbiota composition in laying hens with high stocking density.
