SEC, silver-feathered hens in enrichment cages; SFR, silver-feathered hens in free range; GEC, gold-feathered hens in enrichment cages; GFR, gold-feathered hens in free range.
2)
Raw PE, the original PE (paired-end) reads; Raw tags, tag sequences obtained after splicing; Clean tags, a sequence with low-quality and short-length tags being removed; Effective tags, tag sequence collected for further analysis after filtering the chimera; Avg Len, the average length of effective tags; OTUs number, the number of OTUs obtained per sample.
