Innate immune responses to metabolic stress can be detected in rumen fluids

A difficult issue faced by the farmers without much more knowledge is tried to solve. The solution is understandable but needs much more to further verify and to enable the farmers to be benefitted. Congratulations to authors, as scientists mostly avoid to do research on difficult issues.

I am interested to know how representative sample of rumen liquor can be drawn from cows.

As we go along should Feed Efficiency Genomics Algarythemes be looking at Rumen PH, Rumen Microbiome and certain saliva enzymes to best breed a cow best capable to handle high roughage diets and/or handle high concentrate diets when land and or soil fertility is limited. This revelation could and should take out a lot of fluff and spur better direction of real working enzyme blends and buffers as well as nutritional heat abatement strategies.
I am way out of my Wheel House when I suggest this, but I find it hard to think natural anti-cortisol levels can antagonize feed efficiencies. I believe DNA and DNA editing today and in the future will be the fastest way to address livestock emissions and efficiencies. More latter if not
