| Resumo: |
Reducing the amount of human-edible feed in livestock diets is a key factor towards more sustainable livestock systems. Based on results from a conventional wholesystem study comparing performance, efficiency, land productivity, and profitability of an indoor-feeding system (SH) and a pasture-based dairy production system (VW) in lowlands of Central Switzerland, the net contribution of these systems to human food protein and energy supply was analysed. Depending on the presumed human-edible fraction, the system VW produced between 6.6 and 11.2 times more human-edible protein and 3.5 to 6.6 times more human-edible energy via animal products than the animals consumed via feeds. For the group SH, these factors were clearly lower but still in a positive range (1.0 to 2.5 and 0.9 and 1.9 for protein and energy respectively). In addition, protein quality in the animal products was considerable higher than protein quality in the potentially human-edible feed components.
