Fewer proteins in ecological raw materials
Protein-rich raw materials for pig feed have shown to
contain fewer proteins and more fats when they are grown
This was the result of a digestibility research in finishing pigs at
Wageningen University's Animal Sciences Group in the Netherlands. The research
was carried out for the Dutch ministry of Agriculture, Nature and Food
The research focused on flakes of rape seed, soybean, sunflower
seed, sesame seed and whole ground blue lupins.
ecological grown products, protein content, crude fibre content and ash content
were lower than in conventional products.
The level of major amino acids
as a percentage of crude protein was somewhat higher than in conventional
Up until now, it was thought that
ecological grown raw materials had the same composition and digestibility
coefficients as conventional products. The results however seem to point in a
Researcher Hans van Diepen said, "It's too early to
say that we should use a separate table for ecological raw
The researchers are also doing research into feeds for
ecological kept laying hens.
