| 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... |

| 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... |

| 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... |

| Aim of this study was to test the influence of feeding strategy on faecal particle size distribution as indicator of fibre digestion under on-farm conditions. Seventy-six cows from 11 farms, located in Switzerland and southern Germany were included. Cows were monitored up to eight times during one full lactation. All valid individual test days resulted in a total of 347 datasets. Milk yield and composition were recorded. Diet composition was described in a binary yes/noindication for the presence or non-presence of different roughage components (fresh grass, grass silage, hay, maize silage and straw) and the exact amount of concentrates. Faecal samples were taken at each test day and sieved with a set of four wire‐mesh screens with pore sizes of 4mm, 2mm,... |
