研究发现,肠道微生物与牛的较高性能相关,对减少甲烷排放的计划提出了挑战。 Study finds gut microbes linked to higher performance in cattle, challenging plans to reduce methane emissions.

对澳大利亚牛群的研究表明,其肠胃中排放甲烷的微生物可能与更强大的免疫系统和更好的性能相关联,这表明,如果不进一步研究,这些微生物不应被消除。 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. 发现表现好的幼崽有八种不同的肠道微生物。 Better-performing calves were found to have eight distinct gut microbes. 此外,还发现人工受精可产生在断奶时重量为6千克的幼崽,尽管其成本更高。 Additionally, artificial insemination was found to produce calves that were 6kg heavier at weaning, though it costs more. 最后,传宗接代证明会减少育龄体重和肌肉面积,突出表明在育种过程中需要保持遗传多样性。 Finally, inbreeding was shown to reduce yearling weight and muscle area, underscoring the need for maintaining genetic diversity in breeding.
