| On organic farms, infections of gastro-intestinal nematodes (GIN) in grazing cattle, sheep and goats can have a detrimental impact on animal health, and are therefore of substantial economic importance. The aim of our interdisciplinary project is to investigate the basic conditions for the implementation of a control strategy against GIN based on the use of tanniferous plants. The project combines research on plant growth and management, animal nutrition and parasitology. The first results, especially those from Onobrychis viciifolia (sainfoin), presented here are encouraging. O. viciifolia has a consistently high concentration of condensed tannins (CT) throughout the whole growing season. Thus, the optimal time for harvest can be determined in relation to... |

| Forages rich in condensed tannins have repeatedly shown potential to reduce gastrointestinal nematode infection in sheep. Similarly, several breeds of sheep have shown a relative resistance to gastrointestinal nematodes (GIN). We hypothesised that additive or even synergic effects may arise from the combination of a relatively resistant breed and a diet rich in condensed tannins. In study I, 160 lambs of the native Red Engadine Sheep (RES) and 113 lambs of the Swiss White Alpine sheep (SWA) were artificially infected with GIN and subsequently grazed for 52 days. The lambs were then distributed to 2 groups for a 14-day experimental feeding period. One group received a diet with a proportion of 55% sainfoin and was compared to a control group on the basis of... |

| Gastrointestinal nematodes (GIN) substantially impact on goat health. Because of the widespread development of GIN, resistant to allopathic drugs, further research into alternative parasite control methods is required [1]. Silver fir, Abies alba MILL (SF), is traditionally used by Swiss farmers in order to control GIN infections of goats but also to improve animal welfare. A survey among goat farmers revealed that goat farmers use SF in winter during a period of approximately five months. The SF-ration per animal and day differ between approximately 8.2 g dry matter (DM) to 600 g DM [2]. As there is scientific evidence neither for an anthelmintic potential nor for the feed intake and milk performance of SF, we conducted a study with 30 goats. For a 20... |

| The aim of this experiment conducted at four sites in Switzerland was to investigate the transmission and infectivity of the two main helminth parasite species of poultry (Ascaridia galli and Heterakis gallinarum) in outdoor runs with two different stocking rates. Additionally, the influence of a simplemanagement practice (mowing of run) on helminth transmission was studied. Three run types were created on each site: runs C served as control (stocking rate 10 m2/hen, no management), runs B corresponded to runs C but were managed (10 m2/hen, management). In runs A stocking rates were doubled compared to control runs (5 m2/hen, no management). During two subsequent layer flocks, a set of parasitological parameters (faecal egg counts (FECs), prevalence, worm... |

| tPrevious research has demonstrated the potential of tanniniferous feed sources to reducethe faecal egg count (FEC) of sheep and lambs infected with gastrointestinal nematodes(GIN). The present study investigates the use of sainfoin (Onobrychis viciifolia, cv. Perly)and faba bean seeds (Vicia faba, cv. Scirocco), either as single condensed tannin sources orin combination, to reduce the periparturient rise in the faecal egg count of GIN-infectedewes. Seventy-eight periparturient Red Engadine ewes (PP ewes) and fifteen ewes of thesame breed in early gestation (EG ewes) were used for the study. All animals experiencedan artificial infection with 1500 infectious larvae of Haemonchus contortus 33 days prior tolambing. For a feeding period of 25 days, PP ewes... |

| The aim of this study carried out in 6 commercial layer houses was to examine the effect of litter management on water content, helminth egg count and litter infectiousness with the intestinal nematodes Ascaridia galli, Heterakis gallinarum, and Capillaria spp. Three types of litter management were established in each layer house in parallel: in compartment A, litterwas left undisturbed, in compartment B, wet litter was replaced and in compartment C, new litter material was added weekly. Dry matter (DM) contents of the litter and parasitological parameters (helminth egg concentration in litter samples, faecal egg counts (FECs) in the permanent layer flocks, helminth prevalence and burdens in two series of tracer animals) were determined every 4 weeks during... |

| In der Schaf- und Ziegenhaltung stellt der Befall mit Magen-Darm-Strongyliden (MDS) einen wesentlichen Problemfaktor für die Tiergesundheit dar. Klinische und subklinische Erkrankungen können von erheblicher wirtschaftlicher Relevanz sein. Eine zunehmende Resistenzentwicklung gegen seit langem eingesetzte Anthelminthika hat derzeit einen intensivierten Einsatz dieser Wirkstoffe zur Folge und verschärft das Problem somit zusätzlich. Die Entwicklung und Bereitstellung komplementärer Kontrollstrategien könnte zu einer erheblichen Reduktion des Anthelminthika-Einsatzes beitragen. Eine mögliche Strategie stellt der Einsatz tanninhaltiger Futterpflanzen dar. Wir beschreiben Ergebnisse aus einem in vivo Versuch zur antiparasitischen Wirkung von Esparsettenheu und... |

| Gastrointestinal nematodes (GIN) are one of the most important problems affecting health and therefore performance and welfare in small ruminant husbandry. The control of these parasites in the past strongly relied on the repeated use of anthelmintic drugs. This has led to nematode populations which are resistant to most of the currently available anthelmintics. Furthermore customer’s demands for organic and residue free animal products are increasing. The aforementioned problems have given a strong impetus for the development of new non-chemical strategies to control GIN. Previous research has pointed out the anthelmintic potential of sainfoin (Onobrychis viciifolia) and other tanniferous (CT) feed sources in goats and lambs infected with GIN. A recent... |

| Tanniferous forage plants can have beneficial effects on ruminant productivity and health (improved protein supply, bloat safety and antiparasitic properties). However, condensed tannins can also lower palatability, voluntary feed intake and digestibility. The aim of our interdisciplinary project was to generate basic knowledge on plant management, feed palatability and the antiparasitic properties of tanniferous forage plants for their practical application in agronomy, focusing on their usefulness in controlling gastrointestinal nematodes in organic farming. We found that Onobrychis viciifolia (sainfoin), Lotus corniculatus (birdsfoot trefoil) and Cichorium intybus (chicory) were suitable for cultivation under the given temperate climatic conditions,... |

| Oak and Walnut are both of ethnoveterinary importance, especially for anthelmintic treatment of ruminants [1,2]. H2O and EtOH-water (1:1) extracts of oak and walnut foliage were used for phytochemical profiling and for in vitro assays with Caenorhabditis elegans and gastrointestinal nematodes (GIN). Oak extracts contained mainly tannins, walnut extracts were dominated by flavonoids. Oak EtOH extract caused significant lethal effects in adult C. elegans (LC50 1.5 mg/mL); motility of GIN L3 larvae was reduced by the EtOH extract but at substantially higher concentrations. Egg hatching was inhibited by both, the oak H2O and EtOH extract. In vivo: 42 lactating Alpine goats carrying natural GIN infections were allocated to 3 feeding groups: oak, walnut and... |
