The high-external-input feeding strategy (HID) caused the significantly highest daily weight gain in the suckling period (+14%) and in the whole trial period (+15%) compared to the average of the medium- and the low-external-input feeding strategies which were statistically similar at a lower level. After weaning, HID advantage was only numerical. Piglets’ health status was good and not affected by the four feeding strategies. Only a maximum of 3.3% of the piglets (HID group) had been treated. Animal losses were on a low level and also unaffected by the four feeding strategies. Diet costs for a standard-20kg-piglet increased by factor 1.3, 1.4, and 3.1 for group 3, 2 and 1 respectively, compared to group 4 piglets. Discussion The high-external-input diet (HID) has the smallest amount of farm grown diet components and the highest amount of technologically processed diet components of farm-external origin, the opposite way around to the low-external-input diet (LID) (Table 1). Hence, HID feeding strategy is not fully consistent with organic agriculture which is defined as a low-external-input-system. On the other hand the question has to be answered whether and how it is possible to fulfill the high feed quality demand of piglets within a more or less extensive agricultural system. The results (Table 2) show that even a LID feeding strategy with straw as roughage source seems to be able to generate sound piglets of proper growth performance and good health status without negative effects on animal losses but with positive effects on economy. However a verification of the results is necessary (mainly by use of higher number of piglets and differing seasons) before communicating a final suggestion. This will be realized in the EC-wide Core-Organic-II project ICOPP (Improved Contribution of local feed to support 100% Organic feed supply to Pigs and Poultry). 290
