The microbiological quality of feedstuffs

The quality of a feedstuff is not only defined by the various nutrient contents, or by its composition in terms of raw materials, or its digestibility or its palatability, nor even by its appearance or sensory characteristics, but also by its hygienic status. This article presents a way of assessing the microbiological quality of feedstuff,…

Virulence monitoring and the structure of powdery mildew populations between 2003 and 2010

Breeding for powdery mildew resistant wheat varieties needs information on the presence of virulences and the virulence structure of the current powdery mildew populations. In this work, we present a novel approach for virulence analyses by global analysis and not by analyzing the constituants of the population, as this was done in previous studies. Here,…

The significance of aesthetics for the adoption of no-tillage farming

No-tillage is an effective protective measure against erosion which offers ecological and economic advantages. Although it has spread continually in Switzerland since the mid-1980s and some cantons actively promote its adoption, the share of total agricultural land under no-tillage remains low (4 %). This study on reasons for adoption or rejection of no-tillage shows that…

Chromosome studies and other investigations on equid crossings

Crossings between horses and donkeys are in nature possible and are used as mules or hinnies in agriculture. Other types of crossings are rare and scarcely investigated. Systematic experiments are only allowed with special agreements and are very time consuming and costly and therefore rare. In this report crossings between horse, Przewalski and donkey are…

Motivations for the implementation of ecological compensation areas

Swiss agricultural policy is guided by the goal of improving the ecological services provided by farms through direct payments for ecological compensation areas (ECAs), but evaluation programs have shown that financial incentives alone do not guarantee the implementation of ECAs. We investigated, by means of structured interviews with conventional, integrated production, and organic farmers, which…

Alpine summer farming in Switzerland: surveys on the situation and choice of alpine summer farms

In parallel with agriculture in the lowlands, alpine summer farming is also currently in a state of change. Within the framework of the inter- and transdisciplinary research programme AlpFUTUR, three representative written surveys were carried out in which managers of alpine summer farms as well as of summer-pasturing and non-summer-pasturing home farms were asked for…

Challenges in the environmental monitoring of genetically modified plants

According to genetic engineering legislation in Switzerland, the cultivation of genetically modified plants (GMPs) must be accompanied by environmental monitoring. This environmental monitoring is intended to identify any negative effects on the environment as early as possible so that necessary remedial measures can be taken. Accordingly, the authorities must be in a position to recognise…

Climate change affects welfare of dairy cows

Climate change is leading to higher temperatures across Switzerland, increasing the risk of heat stress in livestock. Analyzing a «Temperature-Humidity Index» at various locations, it could be shown that the risk for dairy cows already grew substantially on a daily average over the past 30 years, whereas the maximum of the index did not change…

Population structure and genetic diversity of Swiss sheep breeds

The year 2010 was declared by the United Nations as the International year of biodiversity. During that year, the Swiss Sheep Breeding Association made herd book data of its four largest breeds available for genetic diversity analyses. Those were Brown Headed Meat Sheep (OX; n=10 858), Black Brown Mountain Sheep (BNP; n=10 964), Valais Black…
