How Digitised are Swiss Plant Production Farms?

Digital technologies are fixed features of modern agriculture – but to what extent are they already being used in Switzerland? A survey conducted by Agroscope provides answers to this question. Digital technologies reduce the physical workload of farming and contribute to sustainable field management. They also enable optimised management decisions based on plant- or soil-related…

Greenhouse gas emissions from coupled dairy-beef production in Switzerland

Coupled dairy-beef systems are of major significance in Switzerland’s cattle sector. Using Swiss reference data, the present study modelled greenhouse gas emissions per cow and year for a range of different milk and meat yield levels. The study also determined the impact on greenhouse gas emissions of using a combination of sexed semen and beef…

Extent of genomic inbreeding in Swiss sheep and goat breeds

The development of modern technologies now allows thousands of genetic markers in an animal’s genome to be revealed by means of DNA genotyping. This information can be used to deduce genomic inbreeding. This is valuable for populations that have no, or only incomplete, pedigree information. Furthermore, differences in the inbreeding of full siblings can be…

Oil seed by-products as alternative protein sources for imported protein-rich feed

The protein-rich, solvent-extracted meals and press cakes of oilseeds are among the most important protein sources used in compound feed worldwide. In Switzerland, 85 % of oil seed by-products have to be imported. Rapeseed and sunflowers are the most important indigenous oilseeds. Domestic production is bound to contractually negotiated quantities and has thus limited expansion…

Cleaning quality and animal behaviour with the use of a dung-removal robot

The use of dung-removal robots on perforated flooring has not been widespread to date. Moreover, scientifically substantiated recommendations for their operation are lacking. In an experiment involving different cleaning frequencies with the Lely Discovery Mobile Barn Cleaner, floor soiling and the behaviour of the cows on perforated flooring were ascertained. The variant with an optimised…

Genetic parameters of protein efficiency in a Swiss Large White pig population

Pork production contributes to environmental pollution through the emission of nitrogen compounds. In addition, pig fattening in Switzerland requires imports of soybean, since the protein requirement of feed cannot be met by domestic plant-protein sources alone. It is therefore desirable to improve protein efficiency, i.e. to achieve a similar protein uptake in the carcass with…
