flag Study finds gut microbes linked to higher performance in cattle, challenging plans to reduce methane emissions.

flag 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. flag Better-performing calves were found to have eight distinct gut microbes. flag Additionally, artificial insemination was found to produce calves that were 6kg heavier at weaning, though it costs more. flag Finally, inbreeding was shown to reduce yearling weight and muscle area, underscoring the need for maintaining genetic diversity in breeding.
