| Organic and many ‘low input’ production standards for pigs require outdoor access, and as a consequence expose the animals to a wide range of potential endo- and ectoparasite infection sources. Conventional anthelmintics are used to control parasitic infections, but their preventive use is banned by the organic standards. The present paper investigates the potential of prevention of infection through better hygiene. Attempts were made to break the infection cycle through thorough pen cleaning 10 weeks after the pigs had been introduced to the pen. Although pen fouling can be reduced, the level of roundworm (Ascaris suum) infection was not reduced. Regular deworming with conventional medication is still required in addition to good hygiene. |

| From December 2017 onward, including non-organic protein sources in diets for organic poultry will no longer be allowed in the EU. Moreover, in the EU the use of synthetic amino acids in organic diets is prohibited. The main dietary challenge in European organic egg production is to fulfill the protein requirement, especially the methionine (Met) requirement of the hens. Currently available Met-rich ingredients are discussed. In the group of ingredients of plant origin, expelled sunflower seed has a relatively high digestible Met content and is also commonly available. Met content of plant ingredients can be increased by selection of high Met varieties and by specifically breeding on high Met content, e.g. by crossing different breeds. Plant processing... |

| The effects of feeding weanling piglets diets with three different levels of three organic protein crops on performance and health were studied. Diets with 10, 20 or 30% field beans (Vicia faba, variety Aurelia, tannin-free), 10, 20 or 30% white lupins (Lupinus albus, variety Dieta, alkaloid-low) and 20, 40 or 60% quinoa (Chenopodium quinoa, variety Atlas, saponin-free) were compared with a control diet containing 15% soybean expeller and 2.2% soybeans. Besides, the apparent ileal digestibility and the apparent total tract digestibility of nutrients of the control diet and the diets with 30% field beans, 30% lupins and 40% quinoa were assessed. At weaning, 1,055 weanling piglets were assigned to one of the 10 experimental treatments. The piglets were... |
