QLF’s ‘Timed-Release’ protein is a urea phosphate solution which bonds the protein source so as to mimic soya in the way it degrades in the rumen. By binding Urea with phosphoric acid, QLF can extend the time taken for the protein to degrade in the rumen; other molassed protein liquids that simply add urea to molasses degrade over a faster time period in the rumen and hence may be utilised less efficiently.
The graph below shows the typical degradation times of unbonded urea solution, soya and QLF’s ‘Timed Release’protein in the rumen. It is clear that QLF’s ‘Timed Release’ protein can be used as a substitute for soya with the same, if not improved performance.
Why use Urea in liquid supplements?
Urea is a highly concentrated source of nitrogen; it contains the equivalent of 287% crude protein! As Urea provides crude protein in such a concentrated form more space is available for other ingredients which can provide energy or other nutrients.
Forage-based diets often cannot provide enough nitrogen for the rumen microbes. As virtually 100% of dietary urea is degraded in the rumen, it helps meet this need. Price is also always a consideration, and urea is an economical source of dietary crude protein.
How does QLF Optimise Urea usage?
This is done in 3 ways:
1. QLF provides a balance of nutrients to enhance microbial activity:
The rumen’s bacteria and protozoa need a balanced diet to grow and reproduce. QLF provides a combination of nutrients needed to boost microbial growth including: NPN for ammonia, sugar for readily-available energy, essential macro & trace minerals* and base levels of natural protein
*Not all products contain vitamins and minerals.
2. QLF spreads the supply of ammonia in the rumen over time:
Binding urea to phosphoric acid slows down the breakdown of urea into ammonia in the rumen. As a result, rumen ammonia values are kept more constant in the rumen and do not peak (as they would should urea be added without phosphoric acid). This leads to a more efficient utilisation of urea, with less being absorbed into the bloodstream as excess ammonia as shown below:
3. The movement of ammonia out of the rumen is significantly slowed by acid conditions (low pH). As fermentation activity increases and additional VFA are produced, rumen pH is optimised. Because QLF is designed to enhance the utilisation of forage diets (i.e. increase intake and digestion) via improved microbial fermentation, feeding QLF encourages optimal rumen pH and minimal ammonia movement to the bloodstream.
