Temporal progression of anaerobic fungal communities in dairy calves from birth to maturity.

Establishment of microbial communities in neonatal calves is vital for their growth and overall health. While this process has received considerable attention for bacteria, our knowledge on temporal progression of anaerobic gut fungi (AGF) in calves is lacking. Here, we examined AGF communities in faecal samples from six dairy cattle collected at 24 different time points during the pre-weaning (days 1-48), weaning (days 48-60), and post-weaning (days 60-360) phases.
