摘要：
The present study was aimed to investigate the effects of the addition of Yingshan Yunwu green tea polysaccharide conjugates (GTPC) on meat quality, immune response and gut microflora in chickens. A total of 200 chickens with average initial body weight were randomly allotted to 4 groups. Intestinal samples were collected at the end of experiment for bacterial culture and microbial community analysis by 16S rDNA gene sequencing using Illumina MiSeq. Chicken breast muscle and serum were also sampled for analysis of meat quality and immune function. The results showed that dietary GTPC addition increased (P < 0.05) chicken breast muscle pH and redness-greenness (a*) value and decreased (P < 0.05) the values of lightness (L*), yellowness-blueness (b*), hardness, toughness and adhesiveness. In addition, dietary supplementation of GTPC increased (P < 0.05) the weight of thymus and bursa and serum concentrations of IgA and IgG. Furthermore, of the 10 bacterial phyla, the predominant taxa across all sampling time-points were Bacteroidetes, Firmicutes, Proteobacteria, and Deferribacteres, representing >97% of all sequences. GTPC increased the abundance of Bacteroidetes and Lactobacillus, and decreased the abundance of Proteobacteria. These findings provided some references of the application of GTPC in the poultry industry. (C) 2020 Elsevier B.V. All rights reserved.
