Three types of bamboo pellets as a ruminant feed: P 1 (ground bamboo ( GB ) cultured with the fungus C eriporiopsis subvermispora ( CGB ) : soybean curd residue ( T ) : soy sauce cake ( S ) in a 5:4:1 ratio on a dry matter ( DM ) basis); P 2 ( GB : T : S = 5:4:1 on a DM basis); and P 3 ( CGB : T : S = 5.5:0.8:3.7 on a DM basis) were prepared. Four wethers were assigned in a 4 × 4 L atin square design experiment to evaluate the applicability of the bamboo pellets. The experimental treatments were C (control): fed alfalfa hay cubes ( AC ) only, and T 1, T 2 and T 3: fed P 1, P 2, and P 3 with AC by 1:1 on a DM basis, respectively. The digestibility of the DM , organic matter and acid detergent fiber of P 1 were significantly higher than those of P 2 and P 3 ( P < 0.05). The total digestible nutrient ( TDN ) contents of AC , P 1, P 2 and P 3 were 56.5%, 60.2%, 53.2% and 47.0%, respectively. No significant differences in nitrogen retention or ruminal pH and NH 3 were observed among the treatment groups. The results indicate that bamboo pellets cultured with C . subvermispora and mainly mixed with soybean curd residue improved nutritional quality of ground bamboo because of its high digestibility and TDN content.
