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 biologically.
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
In the ecological grown products, protein
content, crude fibre content and ash content were lower than in conventional
The level of major amino acids as a percentage of crude
protein was somewhat higher than in conventional products.
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 different
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.
