The purpose of this experiment was to study the apparent digestibility and the effects of (BP) branch/leaf powder supplementation on growth performance and serum indicators in donkeys. The results showed that the apparent digestibility of dry matter (DM), crude protein (CP), crude fiber (CF), neutral detergent fiber (NDF), acidic detergent fiber (ADF), and digestible energy content (DE) of BP branch/leaf powder were 51.88%, 67.27%, 64.86%, 49.59%, 54.73%, 40.87%, and 6.37 MJ/kg, respectively. The average daily gain (ADG) in the 20% group was significantly higher than in the 0% and 30% groups. The serum albumin (ALB) levels in the 0% and 10% groups were significantly higher than those in the 20% and 30% groups, while the serum globulin (GLB) content in the 10% group was significantly lower than in the other groups. The 20% group showed decreased serum triglyceride (TG) levels compared to the other groups. Both the 20% and 30% groups exhibited lower total cholesterol (TC) levels and increased alanine aminotransferase (ALT) compared to the 0% and 10% groups and higher serum lactate dehydrogenase (LDH) levels than the 10% group. The 30% group had higher serum immunoglobulin A (IgA) levels than the other groups, while all three BP branch/leaf powder groups had lower serum tumor necrosis factor (TNF-α) levels than the 0% group. There was a gradual increase in serum total antioxidant capacity (T-AOC) with the increasing amount of BP branch/leaf powder added. In conclusion, the optimal supplemental proportion of BP branch/leaf powder in the diet is 20%. Furthermore, BP branch/leaf powder can improve growth performance, serum immune indices, and antioxidant capacity in Dezhou donkeys.
本实验旨在研究补充（BP）枝叶粉对驴生长性能和血清指标的表观消化率及影响。结果表明，BP枝叶粉的干物质（DM）、粗蛋白（CP）、粗纤维（CF）、中性洗涤纤维（NDF）、酸性洗涤纤维（ADF）的表观消化率及消化能含量（DE）分别为51.88%、67.27%、64.86%、49.59%、54.73%、40.87%和6.37 MJ/kg。20%组的平均日增重（ADG）显著高于0%和30%组。0%和10%组的血清白蛋白（ALB）水平显著高于20%和30%组，而10%组的血清球蛋白（GLB）含量显著低于其他组。与其他组相比，20%组的血清甘油三酯（TG）水平降低。与0%和10%组相比，20%和
