The inappropriate disposal of sugarcane green waste (SGW) frequently results in environmental problems. The use of sugarcane green waste SGW as sheep feed presents a sustainable alternative; nonetheless, its impact on productivity, meat, and milk needs additional research. This study aimed to evaluate the effects of SGW inclusion on growth performance, carcass characteristics, meat quality, and milk production in sheep using a meta-analysis of published studies. Studies were sourced from BASE, CABA, JSTOR, PubMed, Scopus, and WoS, covering publications from 1981 to 2025. The inclusion criteria required original research articles published in peer-reviewed journals that employed a randomized controlled design. A total of 26 articles met these criteria. The meta-analysis utilized a linear mixed model (LMM), while the intraclass correlation coefficient (ICC) and H-statistics were applied to assess heterogeneity. The inclusion of SGW significantly improved average daily gain (ADG) and feed conversion ratio (FCR; p < 0.05). However, carcass parameters, including hot carcass weight (HCW), cold carcass weight (CCW), and dressing percentage (DP), remained lower (p < 0.05). Nevertheless, SGW hydrolysis resulted in a CCW comparable to that of the control group. Meat quality, particularly water content and cooking loss (CL), increased significantly, especially in treatments involving SGW-bagasse and SGW-ensilage (p < 0.05). Additionally, ash content in the meat was significantly higher in the SGW-bagasse (p < 0.05). The water-holding capacity (WHC) at 24 h was also significantly higher in SGW-whole than in the control group (p = 0.01). Regarding milk composition, the addition of SGW significantly reduced lactose and protein levels in sheep milk (p < 0.05), although milk production itself remained unaffected. Overall, SGW exhibited positive effects on sheep productivity without compromising carcass traits, meat quality, and milk production. Further research is needed to determine optimal inclusion rates, assess long-term effects, and explore mitigation strategies to maximize its benefits.
甘蔗绿色废弃物（SGW）的不当处置常常导致环境问题。将甘蔗绿色废弃物用作绵羊饲料是一种可持续的替代方案；然而，其对绵羊生产力、肉和奶的影响还需要更多研究。本研究旨在通过对已发表研究进行荟萃分析，评估添加SGW对绵羊生长性能、胴体特征、肉质和产奶量的影响。研究数据来源于BASE、CABA、JSTOR、PubMed、Scopus和WoS，涵盖1981年至2025年的出版物。纳入标准要求发表在同行评审期刊上的采用随机对照设计的原创研究文章。共有26篇文章符合这些标准。荟萃分析采用线性混合模型（LMM），同时应用组内相关系数（ICC）和H统计量来评估异质性。添加SGW显著提高了平均日增重（ADG）和饲料转化率（FCR；p < 0.05）。然而，包括热胴体重（HCW）、冷胴体重（CCW）和屠宰率（DP）在内的胴体参数仍然较低（p < 0.05）。尽管如此，SGW水解后的CCW与对照组相当。肉质，特别是含水量和烹饪损失（CL）显著增加，尤其是在涉及SGW-蔗渣和SGW-青贮的处理中（p < 0.05）。此外，SGW-蔗渣组肉中的灰分含量显著更高（p < 0.05）。SGW-全株组在24小时时的持水能力（WHC）也显著高于对照组（p = 0.01）。关于奶的成分，添加SGW显著降低了羊奶中的乳糖和蛋白质水平（p < 0.05），尽管产奶量本身未受影响。总体而言，SGW对绵羊生产力具有积极影响，且不影响胴体性状、肉质和产奶量。还需要进一步研究以确定最佳添加率、评估长期影响并探索缓解策略以最大化其益处。
