High self-sufficiency in animal products? Two-thirds of the protein in livestock feed comes from abroad.
Why do 55% and 69% differ? Feed can be measured in three ways: by weight, by energy content, or by protein content. All three measures are differently import‑dependent: 55% by weight, 56% by energy, 69% by protein. Protein is the scarcest nutrient in Swiss feed production, so the import share is particularly high here, mainly because of soy products. There are also large differences between animal species: ruminants such as cattle, sheep, and goats efficiently utilize roughage and source over 9…
