Study finds gut microbes linked to higher performance in cattle, challenging plans to reduce methane emissions.
Research on Australian cattle reveals that methane-emitting microbes in their gut may be linked to stronger immune systems and better performance, suggesting they should not be eliminated without further study.
Better-performing calves were found to have eight distinct gut microbes.
Additionally, artificial insemination was found to produce calves that were 6kg heavier at weaning, though it costs more.
Finally, inbreeding was shown to reduce yearling weight and muscle area, underscoring the need for maintaining genetic diversity in breeding.
