| Gastrointestinal parasitism with helminths and protozoa remains a major threat in cattle and small ruminant production and has been “rediscovered” in pig and poultry production systems operating under organic farming rules because of the requirement to grant outdoor access to the animals. The control of these parasitic infections is a key issue for the economic viability of farms and for animal welfare. Control solutions aim at (i) providing the agronomical bases for parasite control through rational management of pastures; (ii) stimulating the host immune response through different means; (iii) exploring and evaluating the efficacy of new drugs (i.e., phytotherapy, homeopathy and nutraceuticals); and (iv) developing new concepts of application of chemical... |

| Infektionen mit inneren Parasiten gehören weltweit zu den bedeutendsten Gesundheitsproblemen von Schafen und Ziegen. Insbesondere führt die Gruppe der Magen-Darm Strongyliden (MDS) zu beträchtlicher Morbidität und hohen ökonomischen Verlusten. Am Beispiel der englischen Schafzuchtindustrie wurde berechnet, dass die jährlichen durch MDS verursachten fi nanziellen Verluste über 103 Millionen Euro ausmachen (Nieuwhof und Bishop, 2005). Seit den sechziger Jahren wurden MDS mit chemischsynthetischen Medikamenten (Anthelminthika) kontrolliert. Die häufige und teilweise unsachgemässe Anwendung dieser Antiparasitika führte jedoch in den letzten Jahren zu erheblicher Resistenzbildung der Parasiten gegen verschiedene Anthelminthika-Wirkstoffgruppen beim Schaf... |

| 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. |

| The objective of the studywas to examine the effect of dried and ensiled sainfoin (Onobrychis viciifolia) on established populations of Haemonchus contortus (abomasum) and Cooperia curticei (small intestine) in lambs under controlled conditions. Twenty-four parasite naı¨ve lambs were inoculated with a single dose of infective larvae of these parasites 28 days prior to the start of the feeding experiment. Twenty-four days post-infection, 4 days prior to the start of the feeding experiment, animals were allocated to four groups according to egg excretion, liveweight and sex. GroupsAandBreceived sainfoin hay and control hay, respectively, for 16 days. Groups CandDwere fed on sainfoin silage or control silage for the same period. Feeds were offered ad... |

| Management of paddocks for free-range layers requires an effort from farmers to minimize the adverse effects of these systems on animal health (e.g., parasites)and environment (e.g., nutrient accumulation and leaching). In this study, we report results from 2 on-farm experiments conducted to investigate (1) the effects of rotational versus continuous use of the paddocks and(2) the effects of wood chips in the area close to the pop holes (openings to the paddock) with regard to turf quality, nutrient load in the soil, and parasite infections. Rotational use of the hen paddocks led to a lower proportion of bare soil close to the house, but not in more distant regions. Covering the area in front of the house with wood chips did not reduce bare areas. Nitrogen... |

| 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... |

| The aim of this study was to test the effectiveness of physically acting substances (oils and silicas) and plant preparations for the control of the poultry red mite Dermanyssus gallinae (De Geer 1778). Reproduction and survival of fed D. gallinae females were evaluated in vitro for a total of 168 h using the ‘‘area under the survival curve’’ (AUC) to compare survival of the mites between treatments. Four oils (two plant oils, one petroleum spray oil and diesel), one soap, three silicas (one synthetic amorphous silica, one diatomaceous earth (DE) and one DE with 2% pyrethrum extract) and seven plant preparations (derived from Chrysanthemum cineariaefolium, Allium sativum, Tanacetum vulgare, Yucca schidigera, Quillaja saponaria, Dryopteris filix-mas, and... |

| Vor kurzem hat das grosse Forschungsprojekt «LowInput-Breeds» zur europäischen «LowInput»- und Biotierhaltung begonnen. Mit diesem Artikel möchten wir zeigen, welche Arbeiten mit Schafen in diesem Projekt geplant sind und wie Forschungsgruppen aus der Schweiz im internationalen Umfeld arbeiten. Die 21 beteiligten Partner aus Europa und Übersee haben sich zum Ziel gesetzt, mit Hilfe von Management- und Zuchtstrategien die Tiergesundheit und die Lebensmittelqualität bei den wichtigsten Nutztierarten zu verbessern. Das Projekt hat ein Gesamtbudget von 9 Millionen Euro. Es läuft bis 2014 und wird vom 7. Forschungsrahmenprogramm der Europäischen Kommission mitfinanziert. |

| This study investigates meat quality of four autochthonous Swiss ovine breeds, White Alpine (WAS, n=15), Walliser blacknose sheep (SN, n=8), Engadine sheep (EN, n=9) and the Mirror sheep (SP, n=10). Especially for the latter two breeds, which are rare and endangered, information about meat quality and constitution is important for merchandising issues. All lambs (LW 20-25 kg) of each breed were fattened on pasture for 208 d and subsequently slaughtered. Evaluations were carried out for slaughter yield and classifications, pH-value, colorimetry (L*a*b*-System), shear force (Warner Bratzler method) and cooking losses in the Musculus longissimus dorsi. The results showed no meat quality defects in any breed. The main differences between breeds arose... |
