| 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... |

| Im Rahmen des EU-Züchtungsprojektes LowInputBreeds wurde in der Schweiz ein Forschungsnetzwerk mit 40 Braunvieh-haltenden Betrieben aufgebaut. Projektziel ist die Entwicklung geeigneter Selektions- und Zuchtprogrammen zur Verbesserung von Robustheitsmerkmalen für „low-input“ und biologisch wirtschaftende Betriebe. Hierbei werden traditionelle quantitative Züchtungsansätze mit genomweiten Ansätzen verglichen. Beginnend im Herbst 2009 finden sechs Datenerhebungen auf teilnehmenden Betrieben statt. Neben einer einmaligen Blutentnahme zur DNS-Extraktion und Genotypisierung werden zwölf weitere Parameter wie Rückenfettdicke, Körperkondition, Eutertiefe, Temperament u.a. bei gut 1000 Kühen erhoben. Für diese sowie über die Milchleistungsprüfung und lineare... |

| Parameter estimation on low-input dairy shows that it is worthwile to invest into phenotyping of new traits. EBVs based on phenotypes of cows are informative, this might be benefical for integration of genomic data of phenotyped cows into genomic breeding programs. |

| This study investigated the effect of, and interactions between, contrasting crossbreed genetics (US Brown Swiss [BS] x Improved Braunvieh [BV] x Original Braunvieh [OB]) and feeding regimes (especially grazing intake and pasture type) on milk fatty acid (FA) profiles. Concentrations of total polyunsaturated FAs, total omega-3 FAs and trans palmitoleic, vaccenic, a-linolenic, eicosapentaenoic and docosapentaenoic acids were higher in cows with a low proportion of BS genetics. Highest concentrations of the nutritionally desirable FAs, trans palmitoleic, vaccenic and eicosapentaenoic acids were found for cows with a low proportion of BS genetics (0–24% and/or 25–49%) on high grazing intake (75–100% of dry matter intake) diets. Multivariate analysis indicated... |
