| Although the administration of sainfoin is associated with anthelmintic effects, information on the consequences of feeding this legume on product quality is scarce. In the present study we looked at milk quality and yield of goats fed either sainfoin or a non-tanniferous control forage. Twelve lactating goats of the alpine breed were used for the study. They received grass/clover hay for a period of 15 days (grass clover feeding period, GCFP). Then the feed was switched to sainfoin hay (approx. 90 % of daily intake) for another 15 days (sainfoin feeding period, SFP). Both feeds were supplemented with concentrates in order to guarantee isoproteic and isoenergetic feeding throughout the trial. Milk yield and quality (fat, protein, energy and urea) were... |

| Innere Parasiten gehören zu den wichtigsten Infektionserregern weidender Rinder. Zunehmende Resistenzen gegen die Entwurmungsmittel rücken vorbeugende Massnahmen zur Regulierung in den Mittelpunkt. Das Merkblatt beschreibt nachhaltige Regulierungsstrategien die gegen die wichtigsten Weideparasiten des Rindes zur Verfügung stehen. Das Hauptaugenmerk des Merkblattes liegt auf einer parasitenminimierenden Weidestrategie gegen Magen-Darm-Strongyliden. Empfehlungen zur Regulierung des Grossen Leberegels und von Lungenwürmern runden den Ratgeber ab. |

| Introduction: Sainfoin is a high-quality condensed tannin containing forage plant. The knowledge about anthelmintic effects against sheep nematodes and about the influence of plant preservation (e.g. ensiling) on the anthelmintic activity is limited. Method: 36 parasite naïve lambs (6 groups of 6 animals each) were infected with H. contortus (7,000 L3) and C. curticei (15,000 L3). From day 28 until day 44 p.i., groups A1, B1 and C1 received fresh, dried or ensiled sainfoin. Groups A2, B2 and C2 served as respective tannin-free controls. Individual faecal egg counts on a dry matter basis (FECDM) were performed every 3-4 days. On day 44, all animals were slaughtered and adult worm populations were determined. Results: The consumption of sainfoin was... |

| Les vers gastro-intestinaux comptent parmi les problèmes principaux dans la garde de petits ruminants. Les infestations engendrent selon leur importance des pertes considérables au niveau de la productivité et peuvent fortement compromettre la santé des animaux. Depuis plus de 30 ans le contrôle des vers gastro-intestinaux se base sur l’administration de vermifuges. Cependant, certains problèmes apparaissent; les premiers rapports faisant état d’une efficacité réduite de certains vermifuges datent d’il y a 15 ans déjà. Des études plus poussées ont démontré quecertaines populations de vers avaient développé des résistances contre ces préparations. À l’heure actuelle, à l’échelle mondiale les populations de vers gastrointestinaux résistants sont plutôt la... |

| Gastro-intestinal nematodes (GIN) are the most important problem in small ruminant production with regard to animal welfare and economics. The control of GIN currently relies almost exclusively on the use of synthetic anthelmintics. This is unsatisfactory for organic as well as for conventional small ruminant farmers because of rapid increase of resistant GIN populations and risk of residues in meat and milk. Alternatives to synthetic anthelmintics are therefore needed. This poster presents the main alternative control strategies for GIN. The strategies are divided into measures aimed at freeliving GIN stages (grazing management, biological control) and at stages within the host (genetic resistance, vaccination, anthelmintic plants, feeding... |

| 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, cv. Visnovsky) and other tanniferous (CT) feed sources in goats and lambs infected with... |

| The aim of our experiments was to investigate the transmission and infectivity of the two main helminth parasites of poultry (Ascaridia galli and Heterakis gallinarum) under different run and litter management regimes. In experiment (a) two stocking rates were simulated in outdoor runs and the effect of a simple management practice (mowing) on helminth transmission was studied during two subsequent flocks. Stocking rate seemed not to change helminth transmission patterns and repeated mowing of runs did not reduce helminth infections. Lower stocking rates led to a substantial improvement of the run vegetation. In experiment (b) two litter management regimes (replace or add litter material) were compared to unmanaged litter with regard to... |

| Dairy goats, naturally infected with gastrointestinal nematodes, were fed 700g sainfoin- or alfalfa-pellets per day, additionally to a non-tanniferous basic diet. The effect of the feeding on the parasite egg excretion per gramm faeces (EPG) was monitored over a period of 7 weeks. The trial was conducted in parallel at two sites; in France and in Switzerland. At both sites the same quality of sainfoin- and alfalfapellets were used. Compared to the alfalfa group the EPG of the sainfoin fed goats were reduced by 12% in France andby 18% in Switzerland. A repeated measurement analysis revealed no significant difference between the feeding groups at neither site. As it is very likely that the effect of condensed tannins on gastrointestinal nematodes is dose... |

| La qualité de la viande des agneaux de boucherie dépend d’un grand nombre de facteurs. Outre l’âge au moment de l’abattage et le sexe, l’affouragement a une incidence prépondérante. En principe, un affouragement constitué principalement de céréales, comparé à du fourrage plutôt grossier, provoque les plus grandes différences dans la qualité de la viande. Une autre influence très discutée sur la qualité de la viande est la race; on dit que les races primitives comme le Heidschnucke ont une qualité de viande élevée, se rapprochant de celle du gibier. Certaines races primitives suisses ont également la réputation d’avoir une viande particulièrement bonne. Cet article traite de la question de savoir si la viande d’agneau des races Nez Noir du Valais, Blancs... |

| Magen-Darm Würmer sind eines der grössten Probleme in der Haltung von kleinen Wiederkäuern. Infektionen mit diesen Parasiten führen je nach Befallsgrad zu erheblichen Einbussen in der Leistung der Tiere und können deren Gesundheit stark beeinträchtigen. Die Kontrolle von Magen-Darm Würmern stützt sich seit über 30 Jahren auf den Einsatz von Entwurmungsmitteln. Der lang jährige Einsatz dieser Mittel ist aber nicht unproblematisch. Bereits vor 15 Jahren gab es erste Berichte über reduzierte Wirksamkeiten von gewissen Entwurmungsmitteln. Weiterführende Studien brachten den Beweis, dass gewisse Wurmpopulationen Resistenzen gegen die Mittel entwickelt hatten. Gegenwärtig sind resistente Magen-Darm Wurmpopulationen weltweit eher die Regel als die Ausnahme und... |

| The aim of this field study was to investigate interactions between gastro-intestinal nematode (GIN) infection, milk performance and age in goats in order to identify animal groups with higher susceptibility to GIN. On 3 farms (farm A: n = 29, farm B: n = 33, farm C: n = 117 milking goats) fecal egg count reduction tests (FECRT) were performed in summer. All 179 milking goats were enrolled in FECRT and individual milk performance was recorded before and after FEC for FECRT. Furthermore, in early summer and autumn bulk fecal samples were cultured for every farm and GIN genera were determined. |
