N2 - It is possible to reduce the protein content of organic concentrate in the summer time as grazing pregnant sows can obtain more than 100% of their daily SID lysine requirement from the sward. The daily protein- and amino acid requirements were met during pregnancy but not in early and at peak lactation. The total energy requirement of high yielding second parity outdoor sows during a normal Danish summer was found to be around 46 MJ ME/d during gestation and approximately136 MJ ME/d at peak lactation.
