Dairy Cows Fed Botanicals-Supplemented Diets use Energy More Efficiently

A new study by Penn State researchers suggests that supplementing dairy cow feed with capsicum oleoresin, derived from chili peppers, or a combination of that extract and clove oil, could improve feed efficiency and reduce methane emissions.
The study involved feeding these supplements to high-producing dairy cows and monitoring their weight gain, milk production, and methane emissions. The results showed that cows fed the supplements gained weight more efficiently and produced less methane compared to the control group. The researchers believe that capsicum oleoresin may affect energy and nitrogen utilization, while the combination with clove oil may have additional rumen-related effects.
This research suggests that botanical supplements like capsicum oleoresin and clove oil have the potential to improve dairy cow health and reduce their environmental impact.
