文摘
- •
More aged amaranth had lower non protein-N and degradability.
- •
Increasing plant age reduced gas production, but increased methane proportion.
- •
Advancing plant age reduced cellulolytic bacteria without effect on protozoa.
- •
Higher N fertilizer decreased the adverse effect of growth stage on plant quality.
- •
Increasing N fertilization enhanced in vitro ruminal cellulolytic bacteria.
