Heat stress and β-adrenergic agonist supplementation have little impact on the rumen bacterial composition of wether lambs

Cattle are suplemeneted with β-adrenergic agonists prior to harvest. This supplement stimulates the adrenergic system, which is also responsive to stressors. As the supplement and stress alone impact growth efficiency, we are interested in how the combined stimuli to the adrenergic system may alter animal performance. In this study, we investigate the impact of these factors on the rumen microbiome of market lambs using 16s sequencing.

在收割前，牛只被补充了β-肾上腺素受体激动剂。该补充剂刺激了肾上腺素系统，该系统对压力源也具有反应性。鉴于补充剂和压力单独对生长效率产生影响，我们感兴趣的是，对肾上腺素系统的联合刺激可能如何改变动物的表现。在本研究中，我们利用16s测序技术，调查了这些因素对市场羊的瘤胃微生物组的影响。
