研究了高温和湿度胁迫对小母牛瘤胃细菌分子多样性的影响。在第一次试验(平均体重250公斤)中，瘤胃微生物区系组成没有显著变化，而在第二次和第三次试验中(附加变量包括相对湿度和体重)，在环境温度和湿度升高的情况下，瘤胃微生物区系组成有显著差异。这些变化伴随着瘤胃中短链脂肪酸浓度的降低。(C)2007年由爱思唯尔有限公司出版。
The effect of heat and humidity stresses on the rumen bacterial molecular diversity of heifers was studied. No statistically significant changes in the rumen microbiota composition were found in the first experiment (average body mass 250 kg) while in the second and third experiments (additional variables included the relative humidity and body weight), the micobiota composition was significantly different at elevated environmental temperatures and humidity. These shifts were accompanied by the decrease in concentration of short-chain fatty acids in the rumen. (c) 2007 Published by Elsevier Ltd.
