Collection:
Collection ID: | CO002390 |
Collection Summary: | Cecal sample were collected and immediately snap frozen for metabolomics analysis at the end of experiment |
Sample Type: | Cecum |
Treatment:
Treatment ID: | TR002409 |
Treatment Summary: | Half of the animals in each experimental group were challenged with Salmonella Enteritidis (105 CFU/bird) at 24 h after placing. During the first 21 days of the chicken rearing period, Φ-treated group received 0.1% microencapsulated Salmonella-phage (108 PFU/g) encapsulated in Eudragit®L100 (a pH-responsive formulation) with the starter diet feed, and the control group did not receive any phage |
Sample Preparation:
Sampleprep ID: | SP002403 |
Sampleprep Summary: | Cecal contents were lyophilized and homogenated. Then, 10 mg of the sample were mixed with 0.75mL of cold 75% (v/v) methanol, 0.1% (v/v) formic acid, spiked with 10μg/ml formononetin as internal standard. Then, the mix were shaked for 40’ at 20Hz using a Mixer Mill 300 (Qiagen) and centrifuged at 20,000 xg for 15 min at 4°C. The suspension (600μL) was transferred to a new 2-mL conical tube. |

MS Comments: | For the untargeted metabolomic analysis, Compound Discoverer software (Thermofisher Scientific) was used to identify the peaks, peak filtration, and peak alignment, and performed chromatogram alignment, peak picking, and public database (e.g., ChemSpider, KEGG, Metabolika) querying based on accurate masses (m/z). |
