Bonsilage Plus for more usable crude protein in the small intestine

 
Dr Ewald Kramer
 
 

Studies at the University of Hohenheim into protein quality in grass silage confirm it: Bonsilage Plus increases the amount of bypass protein (UDP).

 

The German protein evaluation system for ruminants is based on the principle of usable crude protein in the small intestine (nXP), which is composed of microbial protein (MP) formed in the rumen and bypass protein (UDP). In addition, it is generally known that the amount of UDP in the ration of a high-yielding cow needs to be increased compared with an average-performing cow, in order to meet its nXP requirements.

 

During silaging, the vegetable protein undergoes extensive degradation and conversion processes (proteolysis). The amount of UDP is reduced and non-protein nitrogen (NPN) compounds are produced, including NH3-N, free amino acids (AAs), peptides and biogenic amines. If present in large quantities, these lead to a considerable surplus of nitrogen (N) in the rumen which has to be detoxified to some extent via urea in the liver. This is often at the expense of the animal's health.
