Sugar beet pulp and silage quality

In the next years the sugar beet factories in Switzerland intend to press the sugar beet pulp more strongly. In an experiment we ensiled sugar beet pulp with 20 % (standard) and 27 % dry matter (DM) in order to investigate the influence of the DM-content on the fermentation quality and on the aerobic stability.…

Animal feed analysis using microcopy

Since the appearance of mad cow disease (BSE), most of the animal feeds sold or produced in Switzerland are officially and systematically tested for contamination with animal by-products. The method of analysis consists in fractionating (sedimenting and sieving), followed by coloration and observation under the microscope. Particles of animal origin are recognized by their color,…

Investment costs for larger dairy barns in Switzerland

The aim of the present survey was to evaluate the investments for larger dairy barns in Switzerland based on realized objects. The investments were analyzed on 22 objects built between 1998 and 2001 with an average capacity of 84 animal units (AU) (52 – 190 AU). The capital cost was evaluated based on the construction…

Women in Agriculture Today

The present study examines the position of women in agriculture in Switzerland. It is still the case that many women who work in the agricultural sector today come from a farming background. As a rule, however, their principal training was not in agriculture. Their main spheres of activity are housework, family and gardening, followed by…

The earthworm populations in two soils

The relation between earthworm populations and site properties was studied in a gleyic and in a calcaric cambisol. In the wet gleyic cambisol the earthworm biomass was 54 % higher than in the drier calcaric cambisol. By increasing the aeration of the soil and a more intense mixing of organic and mineral soil constituents, earthworms…

A case study on the growing and marketing of old land races

This paper deals with biodiversity conservation by economic activities in the food and nutrition sector. A case study about the growing and marketing of the wheat species Emmer (Triticum dicoccum) in the region Schaffhausen analyses necessary success factors for the development of similar regional economic activities. Such success factors are the involved regional production capabilities,…

Efficiency: the key to profitable dairying

For profitable dairying, efficient high yielding dairy cows are needed. They can be characterised by a high feed conversion efficiency of over 1.2 kg energy corrected milk per kilogram annual dry matter consumption, by a low age at first calving and a long productive heard life. The annual milk yield is not a sufficient efficiency…

Structure and costs of different protected areas

The Swiss National Park, Biosphere Reserve Entlebuch and Wetland Preserve Glaubenberg in the cantons Obwalden and Luzern are compared with regard to their administrative structure and their costs. It becomes clear that the National Park is administered with more staff than the other areas, as informational services are offered to a large extent. That implies…

Soil nitrogen dynamics in different maize cropping systems

For a better understanding of soil nitrogen dynamics in maize cropping systems, Nmin content of soil and soil water samples from 0 to 100 cm depth were measured periodically in a loamy Cambisol near Zurich, Switzerland, from 1998 to 2000. Maize was sown either with conventional tillage (CT), rotary band seeding (RBS), or no-tillage (NT)…

Impact of different cultivation techniques on yield of maize silage

During the early growth of conventionally cropped maize, the soil surface is usually uncovered for nearly two months. Frequent heavy rainfalls, typical for Switzerland in spring, increase the risk of soil erosion. Cropping systems with reduced tillage intensity are suitable measures to prevent these negative environmental impacts. With rotary band seeding, a new system for…
