Experimental batch of tannin-based feed premix for reducing stable emissions in ruminants

The EU's strategic aim to reduce methane (CH4) emissions, improve air quality, andstrengthen the EU's global leadership in the fight against climate change creates a need to designalternative solutions to reduce greenhouse gas emissions from livestock production. Livestockproduction accounts for about 17 – 20% of the total 30 – 35% of global anthropogenicemissions, representing a significant ecological burden. In addition to contributing to globalwarming, CH4 formation in the rumen results in a loss of 2 – 12% of the animal's metabolicenergy intake. Therefore, the main goal of the SS06020190 project is the development of a newfeed supplement for cattle with an antimethanogenic effect while simultaneously eliminatingthe negative impact on production, health, and animal welfare. In 2024, in cooperation with theproject partner, the company MIKROP Cebin, a functional sample of feed premix for ruminantswas designed to achieve these purposes. A pilot in vivo study conducted on cannulated cowsexperimentally verified the supplement's effect. This experiment monitored the influence of thenew premix/supplement dietary addition on rumen fermentation parameters, the total count andrelative abundance of protozoal genera, and the production of enteric CH4.欧盟为减少甲烷（methane, CH4）排放、改善空气质量，并强化自身在全球应对气候变化斗争中的领导地位而提出的战略目标，催生了研发可降低畜牧生产温室气体排放的替代方案的迫切需求。畜牧生产约占全球人为温室气体总排放量的17%至20%，而全球人为温室气体总排放占比达30%至35%，该领域已然构成沉重的生态负担。除了加剧全球变暖之外，瘤胃（rumen）内生成的甲烷还会导致牲畜代谢能量摄入损失2%至12%。因此，SS06020190项目的核心目标是开发一款具备抗甲烷生成（antimethanogenic）功效的新型牛用饲料添加剂，同时消除其对生产性能、畜禽健康及动物福利的负面影响。2024年，项目团队与合作伙伴MIKROP Cebin公司携手，针对反刍动物（ruminants）设计出一款功能性饲料预混料样品，以达成上述项目目标。研究人员通过对瘘管奶牛（cannulated cows）开展体内预试验，对该添加剂的效果进行了实验验证。本试验监测了日粮中添加新型预混料/添加剂对瘤胃发酵参数、原生动物属（protozoal genera）的总数量及相对丰度，以及肠道甲烷（enteric CH4）生成量的影响。
