| Two similar trials were carried out to examine how dietary inclusion of an easily fermentable carbohydrate source such as chicory roots (Cichorium intybus) may effect established and establishing helminth infections in pigs. In the first trial varying feeding periods with crude chicory roots naturally rich in fructans (primarily inulin) were tested whereas crude chicory roots were compared with dried chicory roots and purified inulin in the second trial. In both trials pigs were infected with 3000 O. dentatum L3-larvae while fed a traditional standard diet. When the infections were well established and patent, experimental diets were introduced and the faecal egg counts monitored. Two weeks before the pigs were slaughtered all animals were infected with... |

| In organic dairy farming, a goal about improved animal welfare and avoidance of the use of chemicals has introduced restrictions in the use of antimicrobials for treatment of infectious diseases. Mastitis is the major cause of antimicrobial treatments in Danish dairy farming. In order to improve and minimise the use of antimicrobials and the risk of antimicrobial resistance in organic farming, a study based on qualitative research interviews with newly converted organic farmers was carried out. Twenty farmers,18–26 months after conversion, were interviewed focusing on mastitis treatment patterns and the farmers’ own perception of possible changes in strategies, choices and daily routines linked to mastitishandling. Antimicrobial treatment was the dominant... |

| Two trials were conducted to examine the effect of chicory included in or as additional plots of the ryegrass–white clover pastures on growth, naturally acquired nematode infections and selectivity of chicory by lambs. In Experiment 1, 31 weaned Texel lambs (36±7 kg) grazed either ryegrass–white clover (CTRL) or ryegrass–white clover–hicory pastures (CHIC). In Experiment 2, 30 weaned Shropshire lambs (32±7 kg) grazed either ryegrass–white clover (CTRL) or ryegrass–white clover with access to small additional chicory plots, which corresponded to 3% (CHIC-LO) or 6% of the total grazing area (CHIC-HI). No consistent differences in live weight gain and nematode faecal egg counts were observed in lambs grazing the different pasture types. Sward height on the... |

| The QLIF project has targeted a variety of issues to make organic animal production (dairy cattle, pig, poultry) more safe, develop alternative methods to promote animal health and improve product quality. This workshop will discuss these aims as well as the QLIF achievements to date. It will also address our way of assessing the quality of our organic farms. We ask the question what the advantages are of doing this by looking at the output of a farm, such as yield, animal welfare and environmental issues. Alternatively, we also want to know what benefits there are in looking at how the farm is organised, via input factors such as housing design, nutrition, management quality. Two invited speakers will state their preference. Legislation, certification and... |

| Pigs are potential sources of contamination with Cryptosporidium spp., which can lead to infection in humans. Cryptosporidiosis in humans is primarily caused by two species, C. hominis and the zoonotic C. parvum, however, other species including C. suis and C. scrofarum are able to cause zoonotic infection. The oocysts can survive for long periods in the environment and are able to resist most disinfectants. In order to estimate the prevalence of Cryptosporidium spp. in organic pigs and to improve knowledge of the epidemiology, the oocyst excretion was monitored at quarterly intervals during the period September 2011 to June 2012 in each of three organic, Danish pig farms. Faecal samples for examination of Cryptosporidium spp. were collected from 994 pigs... |

| Thick-shelled ascarid eggs have been reported to remain infective in the environment for several years, thus posing a prolonged risk of infection to animals and/or humans. The following in vitro study was therefore conducted to evaluate the negative impact of two species of naturally occuring soil microfungi (Pochonia chlamydosporia and Paecilomyces lilacinus), on the viability of Ascaridia galli, Toxocara canis and Ascaris suum eggs. Approximately 150 fresh eggs of individual ascarid species were embryonated on a 2% water agar in Petri dishes with or without a fungus (P. chlamydospria or P. lilacinus). On days 7, 14, 21, 28, 35 and 42 post experimental set up (p.s.), the viability of the eggs in each experimental group was evaluated (destructive... |

| Although Ascaris suum is the most common nematode in pig farms, the on-farm transmission dynamics is not well described. Hence we performed a 1-year field study on organic pig farms, mapping egg contamination levels in pens and on pastures (dry sows, lactating sows and starters) and infection levels in animals. In conclusion, recovery of infective eggs was limited in deep litter compared to shallow litter, but many deep litter eggs were still viable. A. suum transmission takes place both indoors and outdoors. Highly infective bedding material should be stored, composted or treated before spreading on crops and never used for pastures. |

| Although pigs are commonly infected with Cryptosporidium and Giardia duodenalis, and thus potential reservoirs of zoonotic species (or genotypes), little is known about age-related infection levels, seasonal differences and genetic variation in naturally infected pigs. Thus, to characterise seasonal and age-related variation in prevalence and intensity of infections at farm level, (oo)cyst shedding was monitored at quarterly intervals (September 2011 to June 2012) in piglets (n=152), young pigs (n=234), finishers (n=230) and sows (n=240) from three organic, Danish farms. (Oo)cysts were quantified by immunofluorescence microscopy; and representative Cryptosporidium (n=75) and Giardia (n=67) positive subsamples were characterized by amplification and partial... |

| Two experiments studied the effects of dietary chicory against gastrointestinal nematodes in cattle. In Experiment (Exp.) 1, stabled calves were fed chicory silage (CHI1; n = 9) or ryegrass/clover hay (CTL1; n = 6) with balanced protein/energy intakes between groups. After 16 days, all calves received 10 000 Ostertagia ostertagi and 66 000 Cooperia oncophora third-stage larvae (L3) [day (D) 0 post-infection (p.i.)]. In Exp. 2, calves were assigned to pure chicory (CHI2; n=10) or ryegrass/clover (CTL2; n = 10) pastures. After 7 days, animals received 20 000 O. ostertagi L3/calf (D0 p.i.) and were moved regularly preventing pasture-borne infections. Due to poor regrowth of the chicory pasture, CHI2 was supplemented with chicory silage. At D40 p.i. (Exp. 1)... |

| The rising demand for pigs produced in organic farming systems, which require access to outdoor areas and associated increased risk of gastrointestinal nematode infections, is creating growing interest in alternative control strategies. Also development of anthelminthic resistance due to extensive use of anthelmintics is a concern in intensive pig production. Use of chitin-degrading microfungi is one of the options. Extensive research has been conducted on biological control of plant pathogenic nematodes using such fungi, and some fungal species are commercially available for plant protection. In contrast, there are only limited laboratory studies conducted on eggs from nematodes which are animal parasites. The aim of present study is to investigate the... |

| This paper focuses on the changes in production, herd health and veterinary treatments in Danish organic dairy herds during approximately eleven years based on historic data from herds converted to organic milk production before 1990 (old organic herds) compared to herds converted in 1995 and 1999-2000 and herds that are still conventional. Herd size, milk production, the shape of the lactation curve, somatic cell counts and veterinary treatments for mastitis, retained placenta and ketosis are compared over time and between herd groups. The old organic herds differed from the other three herd groups by having lower milk production per cow, lower somatic cell counts and fewer treatments of mastitis. Herds converted in 1995 and 1999-2000 were comparable to... |

| Quarter milk samples from cows with high risk of intramammary infection were examined to determine the prevalence of Staphylococcus aureus (SA) and penicillin resistant SA (SAr) in conventional and organic dairy herds and herds converting to organic farming in a combined longitudinal and cross-sectional study. 20 conventional herds, 18 organic herds that converted before 1995, and 19 herds converting to organic farming in 1999 or 2000 were included in the study. Herds converting to organic farming were sampled three times one year apart; the other herds were sampled once. Risk of infection was estimated based on somatic cell count, milk production, breed, age and lactation stage. The high-risk cows represented about 49 % of the cows in the herds. The... |

| ABSTRACT: Organic livestock production has increased dramatically in recent years in Europe and other parts of the world. The aim of producing livestock under more natural conditions has led to a reversion to primarily outdoor production systems and less intensive housing when indoor, more forage-based diets, and a reduced reliance on external inputs like antiparasiticides. These major changes in livestock production systems may potentially result in re-emergence (or emergence) of parasitic infections. The basic objective of this paper is to give an overview of the available information on parasitic problems in organic livestock production with a focus on northern temperate regions. Furthermore, options for control that target these problems and are... |

| Gastrointestinal nematodes (GIN) in sheep are a common cause of reduced animal welfare and performance, and thus, high economical losses. The emerging drug resistance in GIN prompts for new methods in combating infections. Several studies have indicated an anti-parasitic effect of tannin-rich plants when included in the diet. The objective of this study was to assess the potential in vitro anthelmintic efficacy of tannin-rich extracts from bark of common Norwegian trees (spruce and pine) against GIN of sheep. |
