Four metagenomic pools (SNJ-1 to SNJ-4) were created by equimolar pooling of qualified DNA samples: SNJ-1: Spring wild+captive (1:1 mix of wild/captive feces) SNJ-2: Summer captive  SNJ-3: Summer wild  SNJ-4: Diarrheal samples collected across both spring and summer  These Qualified DNA samples were then submitted to LingEn BioTech Co., Ltd. (Shanghai, China) for metagenomic shotgun library construction. Sequencing was conducted using the Illumina NovaSeq 6000 platform, generating 150 bp paired-end (PE150) reads.
