To improve dietary nitrogen utilization we want to: reduce ammoniaabsorption with an adequate balance of the degradable vs undegradable portion of the protein in the feedstuff, in relation to the degradability of the energy (carbohydrates), and increase amino acid utilization towards protein synthesis to the detriment of oxidation of amino acids: this can be maximized with an adequate balance of amino acids being absorbed.

Protein4
Non-protein nitrogen (NPN) from feed and urea recycled from saliva and from the blood across the rumen wall also contribute to the ammonia pool. (ijabbr.com)
This protein fraction bypasses the rumen but can be utilized by the animal. (ubm.hu)
It is hypothesized that the low solubility of the mimosa protein would favour its escape from the rumen and that decrease in the fermentable substrate in the rumen would create conditions less favourable to the formation of methane. (cipav.org.co)
They have a fascinatingly complex digestive system (the rumen ) that magically turns grass into healthy protein, something very few other animals can do. (butterbeliever.com)

Continuous1
The smaller part of the reticulorumen is the reticulum, which is fully continuous with the rumen, but differs from it with regard to the texture of its lining. (wikipedia.org)
Toxic1
This is largely due to the massive amounts of toxic animal waste being mechanically pooled into large storage lagoons at the CAFOs - the chemical toxins from which pollute the air around them, in addition to seeping into the water supply. (butterbeliever.com)
Neutral1
The rumen has basically a neutral pH when it's healthy and getting grass, and that's very significant for a lot of reasons. (butterbeliever.com)
Wall2
The lining of the rumen wall is covered in small fingerlike projections called papillae, which are flattened, approximately 5mm in length and 3mm wide in cattle. (wikipedia.org)
And the rumen can't deal with acids, and what happens is the acids gradually eat away at the wall of the rumen, creating little lesions or ulcers through which bacteria can pass. (butterbeliever.com)
