Abstract

The environmental impact of methane, a greenhouse gas emitted from ruminants, is a pressing issue and methods to control methane emissions from ruminants are being investigated worldwide. In this study, we investigated the effects of the administration of spent coffee grounds (SCG) on methane production in the rumen in two cows. In the control condition (days 1 and 2), the cows were fed a basic diet twice daily (roughage and concentrate), and in the SCG condition (days 1 and 2) sequentially, the cows were fed the same basic diet and administered SCG into the rumen twice daily. The methane and carbon dioxide concentrations in rumen gas were measured via a fistula after feeding on days 2 in both cases of the study. The measurements were made using a newly developed gas measurement system with a portable gas monitor, and data were obtained for the control condition and SCG condition at each measurement time. The methane ratio at each measurement time was calculated from the methane and carbon dioxide concentrations, and compared between the two conditions. Statistical analysis showed no significant difference between the two conditions in the methane ratios after the morning (P=0.108) and afternoon feedings (P=0.345). However, the methane ratios before the morning (P=0.043) and afternoon feedings (P=0.008) were significantly lower in the SCG condition than in the control condition, suggesting that the administration of SCG may suppress methane production in the rumen.

饲喂废咖啡渣对牛瘤胃甲烷产量的影响。
反刍动物排放的温室气体甲烷对环境的影响是一个紧迫的问题,控制反刍动物甲烷排放的方法正在世界范围内进行研究。在本研究中,我们研究了在两头奶牛的瘤胃中添加废咖啡渣(SCG)对甲烷产生的影响。对照组(第1、2天)分别饲喂2次基础饲粮(粗饲料和精料),SCG组(第1、2天)分别饲喂相同基础饲粮,每天2次向瘤胃中添加SCG。在饲养后第2天,通过瘘管测量两组瘤胃气体中的甲烷和二氧化碳浓度。采用新开发的气体测量系统和便携式气体监测仪进行测量,并在每次测量时获得控制条件和SCG条件的数据。根据甲烷和二氧化碳浓度计算每个测量时间的甲烷比率,并在两种条件下进行比较。经统计分析,上午饲喂后的甲烷比率与下午饲喂后的甲烷比率差异无统计学意义(P=0.108),差异无统计学意义(P=0.345)。然而,SCG组上午饲喂前(P=0.043)和下午饲喂前(P=0.008)的甲烷比率显著低于对照组,说明SCG可能抑制了瘤胃甲烷的产生。
