Animal products as the backbone of protein supply? Without crop feed, Switzerland could produce about 20 % more protein domestically.
Around 60 percent of Switzerland’s arable land is currently used for animal feed. If that land were used to grow food for direct human consumption, the detour through the animal would be eliminated, and more food and protein would be available per hectare. The magnitude of the loss depends on the animal species. Ruminants efficiently convert grass, and according to Mottet et al. (2017) they provide roughly 0.6 kg of human‑edible feed protein per kg of animal protein net suppliers. Pigs and chic…
