FAQ

How much does one tonne of rapeseed yield, after crushing and extraction?
- You get some 400 kg of rapeseed oil and 600 kg of protein feed.

What is a bypass protein?
- A bypass protein is a protein that does not metabolise in the cow’s rumen, but proceeds more or less intact to the intestines where it is absorbed by the blood.

What’s the difference between ExPro and a standard rapeseed meal?
- In the cow’s rumen, ExPro meal takes longer to metabolise than common rapeseed meal, which means that a larger amount of intact meal reaches the intestines. As a consequence, the cow profits from a considerably higher protein content in its feed. In studies where ExPro was compared to standard rapeseed meal, ExPro led to a yield increase of 3 – 4 kg milk per cow and day.

How much ExPro can you add to the total maintenance ration?
- To a high-yielding cow you may add up to 4 – 5 kg per cow and day, or 25 percent of the concentrated feed.

Why use fat in animal feed?
- By adding fat to the maintenance ration, you increase the degree of concentration of the ration. Today’s cows are high-yielding enough to make it difficult to provide the extra energy needed throughout the first part of lactation, without adding some extra fat.

Why do you saponifiy or hydrogenate a fat?
- For a ruminant, unsaturated or unsaponified fat has a negative impact on the rumen’s micro-organisms, or microbes. A saponified or hardened fat passes through the rumen unaffected, and you thus eliminate the negative effect of the fatty acids on rumen microbes. Microbes are of vital importance to the ruminant’s capacity of digesting and metabolising fibres.
