In Switzerland cattle are kept in a range of different production systems and environments: From lowland to mountain area, from intensive to extensive feeding systems and from conventional to organic production systems. Some of these environments can be classified as harsh environments. It is assumed that some genotypes affect traits differently in diverging environments. If that would be the case, genotype x environment (GxE) interactions would cause re-rankings of the cattle’s corresponding breeding values in the breeding value list. |

The survey showed a high interest of the Swiss organic dairy farmers in breeding, suggesting that there is potential to breed an adapted organic dairy cow. However, it is clear that it would be difficult to breed an “organic dairy cow” that would be suitable for all farms. The differences between farms, particularly between mountain areas and valley regions, were notable. As a result, each farm manager has to specify criteria and breeding goals essential for his or her farm and try to pursue and reach these goals with the available services. Existing tools, like the EBI, are widely considered as helpful, but have to be improved with new knowledge, and further possibilities should be developed. The modern dairy cow for the organic sector must have a long... |

Estimations of genotype by environment interactions have been carried out for Brown Swiss dairy cattle in Switzerland. Yield traits were considered as different traits in different environments. Genetic correlations were then estimated for the same trait in different environments. First results from bivariate analyses showed that genotype by environment interactions might exist in the investigated population, especially for fat yield and protein yield. Further analyses are needed to prove genotype by environment interactions in Brown Swiss cattle in Switzerland. |

In organic agriculture site related factors of animal environment can’t be changed to a great extend by using remedies like additional food, concentrates and medicines as it is common in conventional agriculture. Therefore site related environment factors have a great influence on the possibilities of dairy cow breeding and husbandry on an organic farm. Non site related animal breeding can elevate the risk of (metabolic) stress and diseases in cows. The goal of this project was to introduce a new tool for advisers and farmers to estimate and ameliorate the site relatedness of dairy cow breeding and husbandry. The tool should help to characterize and compare “farm types” and “dairy cow types” and to judge if they fit together or not. 12 site related factors... |

This study investigated the effect of, and interactions between, US Brown Swiss (BS) genetics and season on milk yield, basic composition and fatty acid profiles, from cows on low-input farms in Switzerland. Milk samples (n = 1,976) were collected from 1,220 crossbreed cows with differing proportions of BS, Braunvieh and Original Braunvieh genetics on 40 farms during winter-housing and summer-grazing. Cows with more BS genetics produced more milk in winter but not in summer, possibly because of underfeeding potentially high-yielding cows on low-input pasture-based diets. Cows with more Original Braunvieh genetics produced milk with more (i) nutritionally desirable eicosapentaenoic and docosapentaenoic acids, throughout the year, and (ii) vaccenic and... |

Unter dem Projekttitel „SMAll RuminanTs breeding for Efficiency and Resilience (SMARTER)” hat sich innerhalb eines Horizon 2020 Projektes ein internationales Konsortium von 26 Partnern organisiert. Übergeordnetes Ziel des Projektes ist die phänotypische und genotypische Charakterisierung von resilienz- und effizienzbezogenen Merkmalen sowie die Etablierung neuer Zucht- und Managementstrategien. Der Schweizer Teil innerhalb von SMARTER wird von den Partnern FiBL und Qualitas AG geleistet. Im Vordergrund steht das Merkmal “Parasitenresistenz” (Magen-Darm-Strongyliden, MDS) bei Schaf und Ziege. Allerdings werden auch leistungsbezogene Merkmale (Milchmenge und –inhaltsstoffe), im Sinne von Hilfsmerkmalen, berücksichtigt. Teil 1: In einer vorangegangenen... |

Züchten ist mehr als nur eine gute Stierenwahl treffen. Ebenso wichtig ist es, die Möglichkeiten und Grenzen des Betriebes realistisch einzuschätzen. Besonders in der Rindviehzucht können auf dem einzelnen Biobetrieb ansehnliche Erfolge verbucht werden, auch wenn es im Moment noch kein speziell auf den Biolandbau zugeschnittenes Zuchtprogramm gibt. Beat Bapst von der FiBL-Fachgruppe Tierhaltung und Tierzucht setzt sich intensiv mit der Entwicklung einer Rindviehzucht für den biologischen Landbau auseinander. Leistungen spielen dabei zwar auch eine Rolle, aber nielosgelöst, sondern eingebettet ist die Verhältnisse des Betriebs. |
