畜牧业在温室气体排放中占相当大的比例。必须在这一部门建立减少这些气体排放的机制。这就产生了一个研究的需求，评估植物物种或其提取物，以确定其在调节瘤胃发酵的潜力，以减少肠道甲烷排放的目标。马黛茶提取物（YME）是从巴西南部地区广泛消费的植物中获得的，其生物学特性，对瘤胃发酵，肉质和生产参数的研究很少。为此，本研究旨在评估不同水平的YME的包含和分析其对瘤胃发酵率，甲烷排放量和动物生产性能的影响。我们的研究结果表明，列入YME不影响瘤胃发酵参数或表观消化率。近年来，含有次级化合物的植物提取物具有调节瘤胃发酵和改善动物生产性能的潜力，这一点引起了人们的关注。本研究的目的是评估巴拉圭冬青提取物（Ilex paraguariensis ST. Hilaire）（YME）对瘤胃参数的影响。将8头去势牛分为4组，不含YME（0%）的对照组和干物质中含有0.5%、1%和2% YME的3个处理组。列入YME没有显示差异，瘤胃甲烷排放量（CH 4），总表观消化率（p = 0.54）。同样，YME没有修改瘤胃pH值，但积极影响NH3-N，其线性下降的提取物水平在饮食中的增加（p = 0.01）。除异戊酸（p = 0.01）外，YME对短链脂肪酸（SCFA）无影响，异戊酸在2% YME中的浓度较低。我们的研究结果表明，高达2%的YME不影响消化率，瘤胃发酵参数，或短链脂肪酸在瘤胃中的浓度。
The livestock sector contributes a considerable proportion of greenhouse gas emissions. Mechanisms must be developed in this sector to reduce these gases’ emissions. This generates a demand for studies that evaluate plant species or their extracts to define their potential in modulating ruminal fermentation with the objective of reducing enteric methane emissions. The yerba mate extract (YME) is obtained from a plant widely consumed in the southern region of Brazil for its biological properties, with few studies on rumen fermentation, meat quality, and production parameters. For this reason, this study sought to evaluate the inclusion of different levels of YME and analyze its effects on ruminal fermentability, methane emissions, and animal performance. Our results show that the inclusion of YME does not affect ruminal fermentation parameters or apparent digestibility. The inclusion of plant extracts that contain secondary compounds with the potential to modulate rumen fermentation and improve animal performance has gained attention in recent years. The aim of this study was to evaluate the effect of the inclusion of yerba mate extract (Ilex paraguariensis ST. Hilaire) (YME) on the ruminal parameters. Eight castrated cattle were divided into four groups, a control without YME (0%) and three treatment groups with 0.5, 1 and 2% inclusion of YME in the dry matter. The inclusion of YME did not show differences in ruminal methane emissions (CH4), and total apparent digestibility (p = 0.54). Likewise, YME did not modify ruminal pH, but positively affected NH3-N, which decreased linearly as the extract level in the diet increased (p = 0.01). No short chain fatty acids (SCFA) were influenced by YME, except isovaleric acid (p = 0.01), which showed a lower concentration in the inclusion of 2% YME. Our results show that up to 2% YME does not affect digestibility, ruminal fermentation parameters, or the concentration of short-chain fatty acids in the rumen.
