| The objective was to investigate the variation in backfat at weaning and its relations to reproduction results in organic sow herds in Denmark. The study included eight herds and 573 sows. The average backfat at weaning mean�13 mm; SD�4.2 mm) ranging from 10.5 to 17.3 mm among herds shows that it is possible to avoid poor body condition at weaning even with a lactation length of seven weeks or more. No main effect of backfat at weaning on reproduction performance was found, but the probability of a successful reproduction after weaning tended to decrease with decreasing backfat for first parity sows, whereas the opposite was the case for multiparous sows. |

| The objective was to compare the performance and meat quality of two different pig breeds: The modern crossbred Landrace x Yorkshire (LY) and the traditional Danish Black-Spotted (BS) breed. The LY gilts and four of the BS gilts were inseminated with semen from Duroc (D) boars, the remaining BS gilts were served by BS boars. The experiment was performed on 26 gilts over two years. RESULTS: The Black Spotted breed in general had smaller litter sizes and weaned on average in terms of kg piglet 35% less than the modern breed combination. Crossbred piglets of BS×D had growth rates from birth to weaning comparable with piglets of LY×D. Black Spotted first parity sows were significantly fatter and less meaty, and the meat was significantly redder and darker... |

| Possible reasons for the low market share of organic pork may be heavy price competition with conventional produced pork products combined with no or small distinctive characteristics in appearance and quality, both regarding eating quality (flavour, tenderness) and ethical quality (production methods). The overall aim of this study is to identify strategies for a diversified organic pork production with high credibility and superior eating quality based on pigs foraging in the cropping system, use of a traditional breed and no castration. Preliminary results indicate that the use of a traditional breed, the Danish Black-Spotted pig, might be a way to produce pork, which in appearance differ from conventional pork and at the same time improve the... |

| Et europæisk forskningsprojekt med 13 partnere fra ti lande viser gode muligheder for at dække svin og fjerkræs proteinbehov med 100 pct. økologisk foder fra Europa. Med udgangen af 2017 ophører dispensationen om, at op til 5 pct. af foderet på økologiske bedrifter må være af ikke-økologisk oprindelse. En af de største udfordringer ved 100 pct. økologisk fodring er at sikre dyrene de nødvendige aminosyrer, så produktionen kan opretholdes, og dyrevelfærden ikke forringes. I det europæiske samarbejdsprojekt ICOPP har vi derfor undersøgt en række nye fodermidler og fodringsstrategier baseret på lokale ressourcer, dvs. foderemner produceret i Europa. Det har bl.a. resulteret i en omfattende ny fodermiddeltabel og i lovende ny viden om grovfoder. Projektet... |

| Free-range pig production in Northern Europe is characterized by high inputs of concentrate on grassland. This increases risk of nutrient leaching, increases feed costs and puts a pressure on land resources. Pigs’ unique ability to find a part of their food directly in the field where they are kept should be taken into consideration. One below ground field forage characterized by very high yields and with great potential as fodder source is Jerusalem Artichokes (JA) tubers. The nutritional contribution from free-range foraging, growth, feed conversion and behaviour were investigated in 36 growing pigs foraging on JA and fed concentrates restrictedly (30 % of energy recommendations) or ad libitum. Behavioural observations were carried out weekly over the... |

| Innovative strategies in free-range pig production is needed to improve the environmental performance of the system. Based on previous studies, inclusion of trees was hypothesized to improve the system’s nitrogen efficiency. We investigated sow elimination behaviour, faeces load and localisation as well as soil mineral nitrogen load in pasture based individual paddocks with and without access to two rows of poplar (Populus sp.) trees. Unlike expected sows showed no preference for eliminating in the zone with poplars but clearly avoided defecating near the hut, feed and water. Soil mineral nitrogen load showed a heterogeneous pattern as also found in previous studies. In comparison to grass, our results indicated that the poplars had an increased winter... |

| Slagtesvin i frilands- og økologiske besætninger har brug for bedre udearealer. Derfor vil projektet pECOSYSTEM nu bl.a. teste, hvordan særligt indrettede områder med forskellige rodematerialer påvirker svinenes adfærd. Frilands- og økologiske svin der opfedes på stald skal have adgang til udearealer. Det er vigtigt for produktionens troværdighed, at dyrene kommer ud i det fri, men udearealerne fungerer ikke altid hensigtsmæssigt. Grisene har generelt brug for mere stimulirige udemiljøer, end de har i dag. Det var der bred enighed om, da 20 producenter af frilands- og økologiske svin for nylig mødtes med rådgivere, forskere og dyrlæger til en workshop om, hvordan man kan forbedre udearealer og staldforhold til slagtesvin i frilands- og økologiske... |

| BACKGROUND: A sensory panel evaluated the sensory profile of breast meat from five broiler products: two conventional standard products (A and B) and three organic niche genotypes (I657, L40, K8) reared in an apple orchard. RESULTS: Twenty-two sensory attributes were evaluated, and 13 differed significantly between the products. The aromas ‘chicken’, ‘bouillon’ and ‘fat’ scored highest and the ‘iron/liver’ aroma lowest for the niche products. The meat was more ‘tender’, ‘short’ and ‘crumbly’, and less ‘hard’ and ‘stringy’ in the standard products than in one or more of the niche products. Product ‘I657’ was less ‘juicy’ than the rest. ‘I657’ and ‘L40’ were more ‘cohesive’ and tasted more ‘sourish’ and less of ‘sweet/maize’ than the standard products.... |

| The risk of boar taint in entire males is supposed to increase with increased age and weight. Thus, a method to reduce this risk may be to slaughter the pigs at a low age and weight. This strategy is investigated as part of a new concept for organic pig production. It is hypothesised that organic pork has to differ markedly from conventional in order to overcome the heavy price competition. A seasonal outdoor rearing system based on production of small entire males, large female pigs and sows slaughtered after their first litter is believed to be a feasible strategy for producing organic pork with high credibility and superior eating quality. The study included a traditional breed, the Danish Black-Spotted. 17 gilts farrowed in April. Within the first week... |

| Finding ways to motivate pigs to excrete in dedicated areas is of major importance for the environment, human health and animal welfare. This review investigates pigs’ excretory behaviour and the relation to the rearing and housing environment in addition to identifying important knowledge gaps in this respect. Eliminating away from the nest/lying area appears to be innate but evolves over time. Postpartum, piglets urinate and defecate close to the nest, indicating that it is difficult to influence piglets’ choice of elimination area, as this is influenced by the sow’s choice of nest area. At increased age piglets begin to excrete further away from the nest, which is probably related to the fact that piglets start to spend more time away from it. There is... |
