The decomposition of protein

in the rumen is affected by a great many of different factors.




The bacterial protein break down into amino acids can be decreased by:

the selection of components with a low protein degradability that could add to reduce the rapid decomposition of protein compounds in the rumen into amino acids.



The activity of essential oils

In many cases essential oils (classified as secondary herbal metabolites) possess anti-microbial characters. The properties of each of them are dependent on the quality and quantity of their principal constituent.




ProtiSpar - a patented combination of several essential oils:

  • reduces the amino acids break down by "HAP" bacterial strains into ammonia,
  • without any interference of the acetic or propionic acid synthesis, i.e.
  • no adverse effects on milk yield, milk fat and protein content. 



ProtiSpar benefits:


  • effecting an economy in protein supply 
  • relieving the ammonia overexposed liver
  • increases the small intestine protein inflow
  • relieves the energy balance and maintains health and fertility
  • optimizes cost-efficiency in milk production
  • environmental relief by decreased ammonia emission


To be sourced as supplementation in mineral and compound mixed feed, please ask your expert adviser.
