| To determine the current control measures for strointestinal nematodes (GIN) on Swiss organic small ruminant farms, a phone questionnaire was developed and conducted. The survey also aimed to assess the understanding and implementation of possible alternative GIN control options. In total, 52 meat sheep and 58 dairy goat farm questionnaires were completed, and it was found that in general, farmers were aware of the potential benefit of an adequate grazing management to reduce GIN infection. However, practical realisation was often limiting. On average it was stated that adult meat sheep and dairy goats were drenched 1.5 and 1.3 times per animal and year, respectively, whilst lambs and kids were treated 1.6 and 1.3 times per animal and year, respectively.... |

| 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... |

| 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... |

| 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... |
