Silvipastoral agroforestry in the form of forest grazing and wooded semi-natural pastures has historically been very important for the Swedish supply of food and wood products for local use. Since the end of the 1800s, this form of combined productio

Economical profitability of pasture-based beef production is necessary for continued maintenance of semi-natural pastures. In a situation of decreased cattle stocks, there is a potential to castrate male calves from dairy cows and raise them as grazi

To describe a more sustainable food sector, a supply chain approach is needed. Changing a supply chain inevitably means that various attributes of the product and its system will change. This project assumed this challenge and delivered detailed desc

Soybean meal (SBM) is globally used as a protein feed of good nutritional quality, e.g. for calves. However, the environmental impact of soybean cultivation is often questioned and SBM can therefore of ethical reasons be replaced by nitrogen-fixing f

The profitability in organic and conventional milk production systems when using three different dietary proportions (51 %, 62 % and 69 % of dry matter) of high-quality grass silage to dairy cows was calculated. Feed intake and milk production data w

After decoupling EU income support, normal Swedish systems for suckler cow-based beef production are unable to pay the costs of new investments and market wages for labour. New production systems, able to achieve full cost coverage, were identified b
