Diversity of Rumen Bacteria in Canadian Cervids. Rumen Microbes, Enzymes and Feed Digestion-A Review** Y. Wang and T. A. McAllister* Agriculture and Agri-Food Canada Research Centre, Lethbridge, Canada ABSTRACT : Ruminant animals develop a diverse and sophisticated microbial ecosystem for digesting fibrous feedstuffs. Plant cell, 01/12/2009В В· Recent data suggest that the coevolution between reindeer and their heterogeneous diet of arctic plants has resulted in a unique rumen microbial ecosystem within these animals (Sundset et al., 2007). In fact, >90% of the bacterial 16S rRNA genes sequenced from the reindeer rumen represented novel strains (Sundset et al., 2007)..

Microbial populations change with feed type as well as with other environmental influences such as the inclusion of antibiotics in the diet. Plant carbohydrates and proteins are fermented to volatile fatty acids by microbes and both these and the microbial protein produced provide nutrients that are directly utilized by the ruminant host. Rumen The objectives of this study were to investigate the effects of different forage-to-concentrate ratios and sampling times on the genetic diversity of carbohydrate-active enzymes (CAZymes) and the taxonomic profile of rumen microbial communities in dairy cows.
