文摘
- •
We gave rumen degradable (RDP) and/or undegrabable protein (RUP) to cattle fed hay.
- •
Both RDP and RUP were effective in enhance body nitrogen balance.
- •
Fiber degradation was enhanced by RDP supplementation, but not by RUP.
- •
Quality of the forage affected liquid associated bacteria communities in the rumen.
- •
Protein supplementation did not influence bacterial profile in the rumen.
