Background: Rumen microbes play a greater role in host energy acquisition than that of gut-associated microbes in monogastric animals. Although genome-enabled advancements are providing access to the vast diversity of uncultivated microbes, our understanding of variables shaping rumen microbial communities is in its infancy. Viruses have been shown to impact microbial populations through a myriad of processes, including cell lysis and reprogramming of host metabolism. However, little is known about the processes shaping the distribution of rumen viruses or how viruses may modulate microbial-driven processes in the rumen. To this end, we investigated how rumen bacterial and viral community structure …
Effect Of Partially Replacing A Barley-Based Concentrate With Flaxseed-Based Products On The Rumen Bacterial Population Of Lactating Holstein Dairy Cows, E. Castillo-Lopez, J. Moats, N. D. Aluthge, H. A. Ramirez Ramirez, D. A. Christensen, T. Mutsvangwa, G. B. Penner, S. C. Fernando

Aims: The effects of partial replacement of a barley-based concentrate with flaxseed-based products on the rumen bacterial population of lactating Holstein dairy cows were evaluated. Methods and Results: Treatments fed were CONT, a normal diet that included barley silage, alfalfa hay and a barley-based concentrate that contained no flaxseed or faba beans; FLAX, inclusion of a nonextruded flaxseed-based product containing 55-0% flaxseed, 37-8% field peas and 6-9% alfalfa; EXT, similar to FLAX, but the product was extruded and EXTT, similar to FLAX, but product was extruded and field peas were replaced by high-tannin faba beans. The rumen bacterial population was …
The Effect Of Regular Or Reduced-Fat Distillers Grains With Solubles On Rumen Methanogenesis And The Rumen Bacterial Community, E. Castillo-Lopez, C. J. R. Jenkins, N. D. Aluthge, W. Tom, P. J. Kononoff, S. C. Fernando
The Effect Of Regular Or Reduced-Fat Distillers Grains With Solubles On Rumen Methanogenesis And The Rumen Bacterial Community, E. Castillo-Lopez, C. J. R. Jenkins, N. D. Aluthge, W. Tom, P. J. Kononoff, S. C. Fernando

Aims: The effect of feeding dried distillers grains with solubles (DDGS) or reduced-fat DDGS (RFDG) on ruminal methanogenesis and the rumen bacterial community of dairy cattle was evaluated. Methods and Results: Treatments were CONT, a diet with no distillers grains; DG, inclusion of 20% DDGS; rfDG, inclusion of 20% RFDG; and MIX, inclusion of 10% DDGS and 10% RFDG. Methane emission was measured; rumen bacterial community was evaluated by sequencing the V4 region of the 16S rRNA gene. Total methane production remained unaffected. However, feeding distillers grains tended to reduce methanogenesis per unit of feed intake, decreased the abundance of …
