Comparative Analysis of the Methanogen Diversity in Horse and Pony by Using mcrA Gene and Archaeal 16S rRNA Gene Clone Libraries

Table 2

pH and population densities (copy numbers per gram wet weight of feces) of anaerobic rumen fungi, methanogen, and bacteria in feces of the horse and pony.

Total bacteria (×10^10 copy/gram)	2.72±0.81	2.31±0.99
Methanogens (×10^6 copy/gram)	11.30±17.88	4.38±1.48
Anaerobic rumen fungi; (×10^5 copy/gram)	2.31±2.23	1.52±0.80
