        <dc:description>The influence of dietary amino acid levels (recommended, 7% and 14% lower) on performance and carcass quality was studied in organic indoor and outdoor pigs fed ad libitum in a 2-phase feeding system. The outdoor pigs grew faster during phase 2 than the indoor pigs (p=0.001), although feed conversion ratio did not differ (p=0.358). Dressing percentage was higher for outdoor than for indoor pigs (p=0.011) but lean meat content did not differ (p=0.904). The results indicate a discrepancy between pigs housed in different production systems rather than between pigs directed to different dietary amino acid levels. This suggests that growing/finishing pigs fed ad libitum can compensate for dietary amino acid levels lower than the current Swedish recommendations without affecting production results.&#13;
Behaviour was affected by production system and showed that outdoor pigs walked significantly more (p=0.012) and tended to be rooting more (p=0.098) than indoor pigs. Sniffing, nibbling, pushing (p=0.001 for all) and tail manipulation (p=0.002) occurred more often indoors than outdoors. The incidence of pigs seropositive to erysipelas was higher outdoors (χ2-test; p=0.001). Ascaris suum infections were present in both production systems, whereas Eimeria sp only was found among outdoor pigs. &#13;
