16S amplicon survey of chicken gut microbiota via Illumina HiSeq 2000, delivering 40 million reads (10 billion bases) with good quality (97.5% Q20, 92.5% Q30) and zero N content. Characterizes avian intestinal bacterial communities across poultry production systems; the 52.7% GC reflects the typical cecal and fecal microbiota composition in chickens. The substantial read depth enables robust assessment of alpha/beta diversity, pathogenic colonization dynamics (e.g., Salmonella), and probiotic efficacy in commercial poultry operations.
The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
