Ruminal microbiota-host crosstalks promote ruminal epithelial  development in neonatal lambs with alfalfa hay introduction
Ruminal microbiota is gradually established after birth, while microbiota maturation could be highly diverse because of varied solid dietary accessibility. However, how the ruminal microbiota accreted from postnatal hay diets alters rumen epithelial development, and how this affects animal health remains largely unknown.
