The objective of this experiment was to investigate the effects of forage species and feeding systems on ruminal fermentation, microbiota (Butyrivibrio fibrisolvens, Fibrobacter succinogenes and total bacteria) and conjugated linoleic acid (CLA) concentration of milk in dairy goats. Twenty female crossbred Saanen lactating goats (~35 ± 3.0 kg bodyweight) in early to mid-lactation stage were assigned to a 45-day completely randomised-design feeding experiment, with the following four forage (roughage) treatments: cut-and-carry grass (CG), grazing of grass (GG), cut-and-carry leucaena (CL) and grazing of leucaena (GL; n = 5). All animals were given concentrate equivalent to 1.5% of their bodyweight. The grass used in the study was napier Pak Chong 1 grass (Pennisetum purpureum × Pennisetum americanum hybrid). The results showed that irrespective of the type of forage, grazing goats (GG and GL) had a higher (P B. fibrisolvens, F. succinogenes and total bacteria were significantly (P P B. fibrisolvens (involved in the synthesis of milk CLA), resulting in a higher milk yield, and enhances c9, t11 and t10, c12 CLA in goat milk.

更正：饲草种类和饲喂系统对奶山羊瘤胃发酵、微生物群和共轭亚油酸含量的影响

本实验的目的是研究饲草种类和饲喂系统对奶山羊瘤胃发酵、微生物群（溶纤维丁酸弧菌、琥珀酸纤维杆菌和总细菌）和共轭亚油酸 (CLA) 浓度的影响。将 20 只处于泌乳早期至中期的雌性杂交 Saanen 泌乳山羊（~35 ± 3.0 kg 体重）分配到 45 天完全随机设计的饲养实验中，采用以下四种饲料（粗饲料）处理：草 (CG)、放牧草 (GG)、扦插银合欢 (CL) 和放牧银合欢 (GL; n = 5)。所有动物都被给予相当于其体重 1.5% 的浓缩物。研究中使用的草是napier Pak Chong 1 草（Pennisetum purpureum × Pennisetum americanum hybrid）。
