Abstract：The purpose of the experiment was to determine the effect of green tea powder on liver small molecule metabolites of Changshun green-shell laying hens.Thirty-six Changshun green-shell laying hens aged 27 weeks were randomly divided into two groups,namely,a control group and an experimental group(GTP1.5 group),with three replicates in each group and six chickens in each replicate.The control group was fed a basal diet and the GTP 1.5 group was a fed basal diet with 1.5％green tea powder.The pre-test period was 1 week,and the formal test period was 5 weeks.The results showed that compared with control group,31 metabolites were found in GTP1.5 group,among which 28 metabolites were up-regulated and three metabolites were down-regulated.The above metabolites belong to 10 categories,such as amino acids and their metabolites,fatty acyl and glycerophospholipids,among which hyodeoxycholic acid is the most different.KEGG enrichment analysis revealed 11 significant enrichment pathways,of which three were related to amino acid anabolism and four to fatty acid anabolism.The results showed that green tea powder mainly affected the synthesis and metabolism of amino acids,their metabolites and fatty acids in the liver of laying hens.The addition of green tea powder can lead to up-regulation of hepatic hyodeoxycholic acid,which may be related to cholesterol regulation in laying hens.
