  1. 1)The three diets were as follows: RS (free access to rice straw); RSBFS (free access to rice straw and BF-based silage); and BFS (free access to BF-based silage).
  2. 2)BF-based silage (BFS) was a by-product feed-based silage, which was composed of 50% spent mushroom substrate, 21% recycled poultry bedding, 15% ryegrass straw, 10.8% rice bran, 2% molasses, 0.6% bentonite, and 0.6% microbial culture, and was ensiled for over 2 weeks.
  3. 3)Voluntary intake (DM g/d)/feeding time (h/d).

  5. 5)Voluntary intake (DM g/d)/chewing time (h/d).
