224-225: confusion about parity is corrected,
Line 224-225, it states that that no information/security on the productivity data on whether it was primiparous or multiparous sow. Again this creates a bit of confusion. Sows were recorded, 50% primiparous and 50% multiparous to evaluate behaviour, and results are discussed accorging to that (lines 320-321). Why productivity data was not available?
