TL;DR: In this paper, a life cycle assessment (LCA) was conducted using HOLOS (i.e., a whole farm model based on Intergovernmental Panel on Climate Change methodology modified for Canadian conditions that considers all significant CH4, N2O and CO2 emissions from the farm) to establish whole farm GHG emission intensity for beef production in western Canada.

TL;DR: This study shows that the risk of ruminal acidosis is high for cows fed a low F:C diet, particularly when finely chopped silage is used, and intake of dietary peNDF is a good indicator ofRuminal pH status of dairy cows.

TL;DR: It is suggested that risk of acidosis may have little overall effect on general behavior, with the exception of rumination, and identification of these changes in behavior through repeated measurements may assist in the detection of an acidosis event within a herd.

TL;DR: This study indicates that cows become more prone to acidosis over time even though they decrease intake of the challenge grain to avoid acidosis, especially for cows fed diets low in physically effective fiber and at high acidosis risk.

TL;DR: In alfalfa, it seems that effective enzymes work by removing structural barriers that retard the microbial colonization of digestible fractions, increasing the rate of degradation, which is consistent with previous findings of synergism between exogenous and ruminal enzymes.
