leaf is known for its many nutritional and nutraceutical properties, which are essential for the growth performance and well-being of the animal. So, in this review, we aim to use meta-analytical procedures to resolve uncertainty, identify knowledge gaps, and create new insights using published data on the effects of leaf meal (MOLM) on growth responses, hemo-biochemical parameters, and slaughter performance of rabbits. Google and electronic databases were employed to search for studies on feeding rabbit MOLM-based diet (MOLMBD), and the data generated were analyzed using OpenMEE software. Sources of heterogeneity were evaluated using rabbit breed, inclusion levels, study periods, and sex. Results reveal that rabbits fed MOLMBD had similar feed intake (standardized mean difference (SMD) = 0.07; 95% confidence interval (CI): -0.19, 0.05; = 0.001) with higher average daily gain (SMD = 0.86; 95% CI: 0.63; 1.09; = 0.001) along with an improved feed conversion ratio (FCR) (SMD = -0.90; 95% CI: -1.11, -0.69; = 0.001). Additionally, MOLM improved white and red blood cells, while lymphocytes, mean corpuscular volume, and mean corpuscular hemoglobin significantly reduced. Blood plasma and slaughter performance were affected positively by a MOLMBD when fed to rabbits. The study revealed that the inclusion levels, breeds, sex, and feeding duration were responsible for inconsistent results among studies. We conclude that feeding rabbits MOLMBD promotes weight gain and FCR and did not significantly affect feed intake (FI). Further research on the production of and its utility on animal feeds is needed.
树叶因其多种营养和营养保健特性而闻名，这些特性对动物的生长性能和健康至关重要。因此，在本综述中，我们旨在使用荟萃分析程序来解决不确定性、识别知识空白，并利用已发表的关于树叶粉（MOLM）对兔子生长反应、血液生化参数和屠宰性能影响的数据来创造新的见解。我们利用谷歌和电子数据库搜索关于以MOLM为基础的兔日粮（MOLMBD）的研究，并使用OpenMEE软件对生成的数据进行分析。使用兔品种、添加水平、研究周期和性别来评估异质性来源。结果显示，饲喂MOLMBD的兔子采食量相似（标准化均值差（SMD）=0.07；95%置信区间（CI）：-0.19，0.05；P=0.001），平均日增重更高（SMD=0.86；95%CI：0.63；1.09；P=0.001），同时饲料转化率（FCR）有所改善（SMD=-0.90；95%CI：-1.11，-0.69；P=0.001）。此外，MOLM改善了白细胞和红细胞，而淋巴细胞、平均红细胞体积和平均红细胞血红蛋白显著降低。给兔子饲喂MOLMBD时，血浆和屠宰性能受到积极影响。研究表明，添加水平、品种、性别和饲喂持续时间是研究结果不一致的原因。我们得出结论，给兔子饲喂MOLMBD可促进体重增加和FCR，且对采食量（FI）没有显著影响。需要对MOLM的生产及其在动物饲料中的效用进行进一步研究。
