Advantages of fermented protein

Fermented protein, also known as PDGS, has a number of advantages compared to soybean protein, which is used in animal feed today.

By using PDGS from Hveiti, you are guaranteed that the product you receive is always uniform, and that the production process is always the same. This means that a stable nutritional value is guaranteed, so that the product can enter into a carefully prepared diet for e.g. pigs.

PDGS = Protein Distillers Grains with Solubles.

The use of PDGS is advantageous in relation to animal welfare. Because the product, as opposed to soybean, is processed, it makes it easier for the animals to absorb and digest the protein. Especially pigs have a sensitive intestinal system, and by using PDGS, gastric ulcer and intestine failure, which is a big problem in today’s production of pig, is avoided.

The PDGS can also be used in the production of fish. Today, fish protein, which is an article in short supply, is used, but because of the low contents of fiber in the PDGS, it can be used as a substitute for fish protein.

Better phosphorus utilisation

According to the report ”By-products from ethanol production – the forgotten part of the equation” from the Danish Institute of Food and Resource Economics, the fermented protein product has a higher content of calcium, phosphorus and sulphur relative to corn, thereby reducing the need for supplements in feed diets. 

Preliminary analyses suggest that the fermented protein product also has an advantage in relation to phosphorus discharges. 

Phosphorus is an element tied up in protein. When you, through a fermenting process, improve the bioavailability of the protein, you also improve the phosphorus absorption. This means that you lower the need to blend phosphorus into the feed product, which results in both an environmental and economic advantage, as phosphorus discharges is a well-known problem. 

Studies on land use effects of bioethanol production show that the land required for the production of bioethanol is substantially reduced by the feed effect of the co-products like protein feed, reducing land use by 94%.  

Therefore, protein feed from the bioethanol production plays an important role in reducing the pressure on the South American rainforests, as it present an alternative to soybean protein
