متن کاملMolecular diversity of methanogens in feedlot cattle from Ontario and Prince Edward Island, Canada.
The molecular diversity of rumen methanogens in feedlot cattle and the composition of the methanogen populations in these animals from two geographic locations were investigated using 16S rRNA gene libraries prepared from pooled PCR products from 10 animals in Ontario (127 clones) and 10 animals from Prince Edward Island (114 clones).
