A batch culture technique was used to evaluate dry matter (DM) digestibility of corn stover (Zea mays L.) and kudzu, Pueraria montana (Lour.) Merr. after solid-state fermentation (SSF) with a white-rot fungus, Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm. Five dietary treatments consisting of mixtures of corn stover (C) and kudzu (K) in varying ratios, (1) 100C:0K, (2) 75C:25K, (3) 50C:50K, (4) 25C:75K, and (5) 0C:100K, were inoculated with P. ostreatus (MBFBL 400) and subjected to SSF for 0, 35, and 77 days. The study was arranged as a 5 × 3 factorial design with 3 replicates. Grass hay was included in the study as a control. Interactions (P < 0.05) between treatments and fermentation time were noted for the fermentation kinetics. Asymptotic gas was the highest (P < 0.05) for 0C:100K and 100C:0K on day 77. Treatment effect (P < 0.001) and treatment × fermentation time interaction (P < 0.001) were noted for in vitro dry matter digestibility (IVDMD). On day 77, treatment 4 had the highest (P < 0.001) IVDMD value, while treatment 1 had the lowest (P < 0.001) IVDMD. There was no difference (P > 0.05) between treatments 3, 5, and control. Numerically, the ranking of their IVDMD values from the highest to the lowest is 4 > 2 > 5 > control >3 > 1. The results show that the treated corn stover and kudzu mixes were comparable with the control, which is good quality hay. This is the first report that demonstrates the potential use of a combined mixture of corn stover and kudzu in ruminant animal feed development.

使用分批培养技术评估玉米秸秆 ( Zea mays L. ) 和葛根 ( Pueraria montana (Lour.) Merr. ) 的干物质 (DM) 消化率。在用白腐真菌Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm进行固态发酵 (SSF) 后。五种日粮处理，由不同比例的玉米秸秆 (C) 和葛根 (K) 的混合物组成，(1) 100C:0K，(2) 75C:25K，(3) 50C:50K，(4) 25C:75K，和(5) 0C:100K，接种P. ostreatus (MBFBL 400) 并进行 SSF 0、35 和 77 天。本研究采用 5 × 3 因子设计，重复 3 次。干草被包括在研究中作为对照。互动 ( P < 0.05) 处理和发酵时间之间的发酵动力学被注意到。 在第 77 天，0C:100K 和 100C:0K 的渐近气体最高 ( P < 0.05)。 处理效果 ( P  < 0.001) 和处理 × 发酵时间相互作用 ( P  < 0.001) 注意到体外干物质消化率 (IVDMD) ）。在第 77 天，治疗 4 的 IVDMD 值最高（P < 0.001），而治疗 1 的 IVDMD 值最低（P  < 0.001）。没有区别（P > 0.05) 在处理 3、5 和对照之间。从数值上看，它们的IVDMD值从高到低排列为4>2>5>对照>3>1。结果表明，处理后的玉米秸秆和葛根混合物与对照相当，为优质干草。这是第一份展示玉米秸秆和葛根混合物在反刍动物饲料开发中的潜在用途的报告。
