| In this study, organically raised pigs received an increasing proportion of grass silage up to 10 and 20% dry matter in the daily ration in the grower and finisher period, respectively, to determine the effects on feed intake and growth performance. The pigs receiving a mixture of grass silage and compound feed ingested 0.3 kg DM/d (13% of their daily ration) as grass silage and realised a similar daily net energy intake as pigs fed compound feed only. However, the silage fed pigs realised a lower daily gain (37 g/d) and a lower calculated net energy utilisation (1.6 MJ/kg) for gain and a lower dressing percentage (1.1%) of the carcass. The nutritive value of grass silage for growing pigs requires further investigation to clarify and minimise the loss in... |

| 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... |

| This study was conducted to determine whether the supply of grass silage or grass silage mixed with barley or CCM to organically raised gestating sows would allow a reduction of compound feed allowance without loss in animal performance. On average, sows fed grass silage or mixed silage were able to compensate for a pre-set reduction of 1 kg or 1.5 kg compound feed, respectively. However, the variation in silage intake between individual sows was large, with a number of mainly young sows consuming less silage than the required amount. Consequently, these sows showed a net back fat loss during the experimental period from d 7 of gestation to weaning. Our results indicate that more feeder space than 1 for 8 sows is required to allow adequate silage intake in... |
