The objective of this study was to determine if device that simulate methane capture equipment (DSMC) located in the frontal part of the head of dairy cows affect animal welfare using productive, behavioral, biochemical and physiological indicators. Twenty Holstein dairy cows were assigned to one of the two following treatments: cows with DSMC (CDSMC, n=10) and cows without methane capture devices (CC, n=10). Treatment did not affect neither milk production nor biochemical blood. The group CDSMC tended to ruminate less (P=0.06) and tended to eat more (P=0.08) frequently than the group CC. In conclusion, considering the data set, the welfare of the cows was not significantly affected by the use of DSMC located in their heads.
本研究旨在通过生产性能、行为、生化和生理指标来确定位于奶牛头部前部的甲烷捕获设备模拟装置（DSMC）是否会影响动物福利。将 20 头荷斯坦奶牛分配到以下两种处理方式之一：带有 DSMC 的奶牛（CDSMC，n=10）和没有甲烷捕获设备的奶牛（CC，n=10）。处理方式对牛奶产量和血液生化指标没有影响。CDSMC 组的反刍时间减少（P=0.06），采食频率增加（P=0.08）的趋势比 CC 组更为明显。综上所述，考虑到数据集，奶牛的福利并未因使用位于头部的 DSMC 而受到显著影响。
