| The object of the study was to test the effect of (i) two different terminal sire lines (Danish Duroc, Du vs. Piétrain, Pi) and (ii) two different feeding strategies (without (-) vs. with (+) raw potato starch prior to slaughter) on performance, carcass quality, and meat quality in organic intact male pig fattening in connection with boar taint reduction. The results confirm the known differences between both genotypes also in intact male growing-finishing pigs. The feeding strategies remained without noteworthy effect. Hence, the choice of terminal sire genotype can completely be adjusted to the requirements of the marketing goal. But the present results still do not justify a final recommendation concerning the choice in connection with boar taint... |

| Die Mast intakter männlicher Tiere stellt eine Alternative zur Ferkelkastration dar. Neben dem Problem des Ebergeruchs, verursacht durch die Leitsubstanzen Skatol und Androstenon, unterscheiden sich Eber in der Mastleistung, der Schlachtkörper- und Fleischqualität. Ziel dieser Arbeit ist es, zwei verschiedene Endstufeneberherkünfte und zwei verschiedene Fütterungsstrategien im Hinblick auf Mastleistung, Schlachtkörper- und Fleischqualität miteinander zu vergleichen. Dazu wurden auf dem öko-zertifizierten Versuchsbetrieb des Thünen-Institutes für Ökologischen Landbau in Trenthorst bis jetzt 147 Eber bis zu einer Lebendmasse von 115 kg, aufgeteilt in vier Versuchsvarianten, zwei verschiedene Endstufeneberherkünfte (Pietrain, Duroc) und zwei... |

| Based on organic agriculture´s aim to produce as regionally and self-sufficient as possible, animal feeding should be mainly based on home-grown feedstuff. This poses a special challenge in feeding of piglets, who require highly digestible diets and highquality protein. Therefore, a feeding trial was conducted to compare various singlephase, 100% organic feeding strategies for piglets before and after weaning, differing in the proportion of home-grown feeds. Each strategy consisted of one out of three concentrates and one out of two roughages. The type of roughage did not affect animal performance, but the concentrate with the highest proportion of home-grown feed and accordingly lowest quality led to significantly slower growth, while the concentrate... |

| Fattening of entire male pigs is a useful alternative to piglet castration but the problem of boar taint is still unresolved. The object of the present study was to test the effect of (i) two different terminal sire lines (Danish Duroc, Du vs. Piétrain, Pi) and (ii) two different feeding strategies (without (-) vs. with (+) raw potato starch prior to slaughter) on the prevalence of boar taint in organic pork production. The results show that entire male growing-finishing pigs of Du origin have significantly higher androstenone concentrations in shoulder back fat than those of Pi origin whereas the feeding strategy has no significant effect. Concerning skatole, both genetic origin and feeding strategy significantly affect concentrations in shoulder back... |

| In organic farming, appropriate protein feeding is challenging based on regional or farm-grown resources. Therefore, feeding maize-bean-silage to dairy cows and fattening pigs could be a viable option to increase the protein content in the diet. However, anti-nutritional compounds might impair animal performance. When exchanging maize silage with maize-bean-silage in the diet of dairy cows, no detrimental effects could be detected. Similarly, the on-top feeding of maize-beansilage to pigs revealed no differences in regard to animal performance compared to a grass-clover diet. Thus, the inclusion of a certain amount of maize-bean-silage in the diet of dairy cows and fattening pigs had no negative effects on the animals. Further studies are going to... |
