Gas production methane (ch3), carbon dioxide (co2) Cyclical rumen contractions occur continuously at rate of about 1/min. Major source of amino acids for the ruminant animal. Rumen microbes convert plant protein into microbial protein. Microbes killed in abomasum & digested in si. Urea by product of our protein breakdown. Can feed a little of it to ruminants.
