Digital technologies represent an opportunity for the modern management of farms. For this, already available technologies must also be utilised in practice. An Agroscope survey illustrates the status quo of technology use.
Farms operate with a balanced nutrient cycle. Agroscope adjusted the reference values for suckling calves to the latest advances in animal production. The values for feed intake and nutrient excretion are now lower.
Protecting sheep from large predators means more work and higher costs for alpine farmers. The economic consequences of the necessary adjustments were investigated in 2017 and 2018 on 13 alpine farms in the cantons of Uri and Valais.
Grassland-based milk and meat production promotes the site-specific feeding of ruminants. With the AP22+, the reduction of protein supply via concentrates is under discussion. Agroscope studied the effects of limited protein supply.
Kaolin was tested in viticulture to control the dreaded pest Drosophila suzukii. The trials showed that this natural product has a comparable efficacy to conventional insecticides without any adverse effect on wine quality.
The risk of nitrate leaching is higher in field vegetable production than in arable crops or grassland. Different species of vegetables have different leaching potentials, which can be reduced through appropriate management.
The Swiss agricultural sector currently makes little use of the opportunities offered by digitalisation. A charter launched in 2018 aims to further develop the digitalisation of the Swiss agricultural and food sector and to exploit the potential in the interests of all stakeholders.
Since 2007, only free-farrowing pens may be used in Switzerland. Since then, litter size has increased significantly. Despite this, piglet mortality during the lactation period has remained stable over the years.
The number of farms with a minimum area of 30 ha is growing, and specialisation – particularly in animal production – is on the increase. Even so, structural change is proceeding at a slower pace in Switzerland than in neighbouring countries.
Alternatives to antibiotics must be found to combat antibiotic resistance in animal production. The forage plant sainfoin reduces postweaning diarrhoea in piglets, thus reducing the need for antibiotic treatment.
Grazing dairy cows is a characteristic feature of Swiss agriculture. In order to use pasture efficiently, the estimation of herbage mass is recommended. Agroscope compared two methods and developed estimation formulas for implementation in practice.
The term ‘agrobiodiversity’ refers to the variety of plant cultivars and species that feature in the human diet. A study in four European countries shows that consumers are interested in this diversity. The genetic diversity of food-crop varieties and species is archived in state gene banks, and continues to serve as a starting point for…
Sowing oilseed rape with other plants reduces damage caused by adult flea beetle, according to a study conducted at Agroscope. This intercropping approach could limit reliance on insecticides and the emergence of resistant pests.
Adapted, productive grass cultivars are crucial for Swiss forage production. Over the past 30 years, the most important grass species – perennial ryegrass – has been substantially improved by breeding.
Farms operate with a balanced nutrient cycle. Agroscope has adjusted beef-cattle reference values to the latest advances in animal production. The said values can be used for fertilisation planning and are to be used for the assessment of the farm- based nutrient cycle.
To protect Swiss cheeses from counterfeiting, Agroscope has developed marker cultures from lactic acid bacteria that allow the origins of the cheese to be determined. Proof-of-origin cultures for extra-hard cheeses are now also available.
From 2016 to 2018 inclusive, Agroscope tested 54 varieties of red clover (Trifolium pratense L.) at six locations. Of these, 25 were new varieties and 29 were already-recommended varieties that were being retested. Yield, vigour, juvenile development, resistance to leaf diseases and anthracnose, winter-hardiness and persistence were all evaluated. For the persistent “mattenklee” type, the…
As part of a farm survey, data on the solid feed intake and liveweight development of suckler calves from birth to the age of 305 days were collected and analysed. The data were used to derive estimation formula on weight development and solid feed intake of suckler calves in Switzerland. The analysis showed that weight…
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…
In order to understand the diversity of insects colonizing oilseed rape, a survey focusing on beetles was conducted in a plot of winter rape in Agroscope Changins (Prangins VD). Beetles were captured with yellow water bowls over the whole cultivation period from August 2017 to June 2018. In total, 11,856 individuals were caught from exactly…
Recent studies show a decline in the abundance and diversity of wild pollinators, as well as an increase in honeybee mortality. These pollinators are an integral part of biodiversity and play an essential role in the growing of certain crops and in wild plant reproduction. In the Swiss cantons of Vaud and Jura, and in…
Plastic products are omnipresent in our everyday lives and are so versatile and efficient that it is difficult to imagine modern agriculture without them. However, in combination with littering and as foreign materials in digestate and compost fertilisers, they are also the main source of plastic inputs on agricultural land. Using material flow analysis, this…
Für Filippo Lechthaler ist es wichtig, dass seine Forschung
auch einen Praxisbezug hat. «Daten direkt im
Feld erheben und Berechnungen machen, die das Leben
von Menschen verbessern können – das motiviert mich»,
sagt der 37-Jährige.
Die Digitalisierung betrifft inzwischen alle Lebensbereiche
und wird häufig als Megatrend bezeichnet. Auch der Wissenstransfer
im LIWIS1 läuft vermehrt digital ab. Die von der
AGRIDEA durchgeführte Online-Befragung gibt einen Einblick
in die Art und Weise der Benutzung verschiedener Medien und
zeigt Unterschiede zwischen Akteursgruppen.
Während des grossen Ausbaus der Mechanisierung in
der Landwirtschaft in den 1960er-Jahren wurde die FAT,
die Eidgenössische Forschungsanstalt für Betriebswirtschaft
und Landtechnik gegründet. Eine Auswertung
der Publikationsreihen zeigt, wie sich die Schwerpunkte
der Forschung verschoben haben.
Drosophila suzukii is an invasive species recently introduced in Europe and causing damages to fruit production. Trichopria drosophilae is considered one of the most suitable indigenous parasitoid to be used in biocontrol programs against D. suzukii. To characterize genetic variability and the spatial genetic structure of populations of T. drosophilae, we developed 21 species-specific molecular…
As part of a milk processor’s annual winter campaign for monitoring the contamination of raw milk with anaerobic spores harmful to cheese – also called butyric acid spores – the analysis methods currently used in Switzerland (MPN method according to CNERNA and filtration method according to Bourgeois) are compared with a new method (SY-LAB). To…
The third beef tenderness survey campaign was carried out during the final trimester of 2018. One hundred sixty-eight samples of beef were purchased in retail outlets, as well as 38 pork fillets for purposes of comparison. Some of the samples were also analysed as part of the beef origin verification program set up by the…
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…
Saprophage insects convert diverse biowaste streams into protein- and fat-rich insect biomass generated independently of arable land. Since 2017, 7 insect species have been approved for fish feed in the EU so far. The most promising species are: black soldier fly (SF; Hermetia illucens), house fly (HF; Musca domestica), mealworm (MW; Tenebrio molitor), and house…
