The impact of feed efficiency selection on the ruminal, cecal, and fecal microbiomes of Angus steers from a commercial feedlot
Feed is the greatest cost of animal production, so reducing it is critical to increase producer
profits. In ruminants, the microbial population within the gastrointestinal tract (GIT) is critical …
