在成年雄性羊身上研究了在芥菜（Brassica Campestris）秸秆（MS）基完全饲料块（CFB）中添加树叶对养分利用和瘤胃发酵的影响。准备了四种类型的 CFB 日粮（粗粮：精料：糖蜜，70:25:5）。压实过程使 MSB、MSNL、MSSL 和 MSAL 的堆积密度 (g/cm3) 分别增加了 2.9、1.79、2.40 和 2.26 倍。 MSSL和MSAL的干物质摄入量（克/天）高于MSB（P<0.05）。由于树叶的加入，粗蛋白和半纤维素的消化率有所增加（P<0.05），而干物质和有机质的消化率则略有改善。然而，树叶的加入并不影响中性洗涤纤维、纤维素和能量的消化率。 MSAL 中瘤胃中总挥发性脂肪酸的浓度显着高于 MSB 或 MSSL 中。各组血液生化参数均在正常生理范围内。
The effect of inclusion of tree leaves in mustard (Brassica campestris) straw (MS) based complete feed blocks (CFB) on nutrient utilization and rumen fermentation was studied in adult male sheep. Four types of CFB diets (Roughage:Concentrate:Molasses, 70:25:5) were prepared. The compaction process increased bulk density (g/cm3) of MSB, MSNL, MSSL and MSAL by 2.9, 1.79, 2.40 and 2.26 times, respectively. The dry matter intake (g/day) was higher (P<0.05) in MSSL and MSAL than in MSB. Digestibility coefficients of crude protein and hemicellulose increased (P<0.05) due to inclusion of tree leaves, while digestibility of dry matter and organic matter showed small improvement. However, inclusion of tree leaves did not affect digestibility of neutral detergent fibre, cellulose and energy. The concentration of total volatile fatty acids in rumen was significantly higher in MSAL than in MSB or MSSL. Blood bio-chemical parameters were within the normal physiological range in all the groups.
