Abstract Two experiments (in vitro and in vivo evaluation) were conducted to evaluate the ability of three different tanniniferous legumes to replace berseem hay on ruminal fermentation, digestibility and methane (CH4) emission. Berseem (Trifolium alexandrinum L.) hay (BH) was considered as control, or replaced at 50% with Acacia saligna (AS), Leucaena leucocephala (LL) or Atriplex halimus (AH) on a DM basis. In Experiment 1 (in vitro evaluation), in vitro ruminal degradability, gas and CH4 production were measured. In Experiment 2 (in vivo evaluation), twelve Barki rams weighing 43.29 ± 0.13 kg were randomly assigned into 4 treatments and individually fed the BH, AS and LL diets for 30 days (21 days for adaptation, 7 days for digestibility and N balance and the subsequent 2 days for CH4 measurements). Results of Experiment 1 showed that AS, LL and AH diets decreased (P

鞣质豆科植物减少甲烷产生和提高巴尔基公羊饲料利用率的能力：体外和体内评估

摘要 进行了两个实验（体外和体内评价），以评价三种不同的单宁豆类植物在瘤胃发酵、消化率和甲烷 (CH4) 排放方面替代 berseem 干草的能力。Berseem (Trifolium alexandrinum L.) 干草 (BH) 被认为是对照，或在 DM 基础上用 Acacia saligna (AS)、Leucaena leucocephala (LL) 或 Atriplex halimus (AH) 替代 50%。在实验 1（体外评估）中，测量了体外瘤胃可降解性、气体和 CH4 产量。在实验 2（体内评估）中，将 12 只体重 43.29 ± 0.13 kg 的 Barki 公羊随机分配到 4 个处理组，分别饲喂 BH、AS 和 LL 日粮 30 天（21 天用于适应，7 天用于消化率和 N 平衡以及CH4 测量的后续 2 天）。实验 1 的结果表明，AS，
