A comprehensive stewardship of genetic resources is necessary to insure a resilient and sustainable agriculture. Most of our food comes from a handful of domesticated species which diversity is constantly shrinking. On the contrary, modern genomics keep discovering the marvels of diversity contained in genetic resources for food and agriculture. High-throughput sequencing and related techniques…
Persistent contaminations with propionic acid bacteria and Lactobacillus parabuchneri in milking systems have repeatedly resulted in financial losses in cheese processing. Moreover, histamine in the cheese, caused by Lactobacillus parabuchneri, can also affect consumer health. Biochemical and molecular biological methods have been developed and introduced into practice to enable the quick and reliable identification of…
More and more farm-manager couples plan and discuss everyday tasks on the farm and for the family jointly, in order to achieve greater flexibility in accomplishing their work. The available planning tools and work budgets for work on the farm and in the household are, however, based on different data sources. In some cases, data…
When it comes to developing recommendations for action for limiting administrative work, knowledge about both the perception of work and the actual work is important. This topic was investigated using the example of the Programme for the Promotion of Grassland-Based Milk and Meat Production (GMMP). A survey of 892 farmers revealed that the perception of…
Preserving soil fertility is a major challenge for farms without livestock specialised in field crops. Several decades ago, several trials were set up at the Agroscope experimental station in Changins to study the long-term effects of different cultural practices on soil fertility and crop yields. This article summarises the main results obtained in these trials.…
The «Agriculture-Related Environmental Objectives» (AEOs) set binding targets for the conservation of species and habitat diversity in the agricultural landscape. For these, lists of species meriting particular consideration (AEO species) were drawn up. An initial evaluation of the ALL-EMA «Agricultural Species and Habitats» Monitoring Programme shows that in Switzerland, on average only 13 % of…
The addition of fatty feed components to a dairy cow ration can influence ruminal fermentation, and hence methane formation in the rumen. In a study with 33 Holstein / Red Holstein dairy cows, the influence of two different types of oilseeds (extruded linseed and ground rapeseed) versus a control (rumen-stable fat) was investigated over a…
To promote efficient grassland utilisation and reduce resource use, it is necessary to minimize the amount of concentrates fed to ruminants. Research findings and practical knowledge are available concerning dairy cow management without concentrates, but there is not much literature on rearing calves without concentrates. Textbooks on animal feeding usually recommend calf rearing with concentrates.…
A fattening trial combining two groups of 15 bulls each was carried out at the Agroscope Posieux site in order to study the influence of the shredlage harvest method compared to the conventional method for ensiling whole-plant maize. The animals were crossbreds between a dam from a dairy breed and a sire from a beef…
A trial was carried out to determine the organic-matter digestibility and nutritional value of whole-plant maize silages (WPMS’s) harvested in different ways. Four methods were compared: standard WPMS from the tower silo removed with a silo unloader, standard WPMS in bales, WPMS shredlage, and cob-enriched WPMS (power maize). According to the chemical analyses, the nutritional…
Today, in addition to maize silages with a standard chop length of 5 to 10 mm, shredlage with a longer chop length (26 to 30 mm) and power maize with a higher proportion of cobs are also produced. At Agroscope, digestion experiments with sheep as well as fattening bull experiments were conducted comparing the use…
Just 20 years ago, over half of the genetic material for the breeding of Braunvieh cattle was imported – primarily from North America – despite the fact that Switzerland is the genetic centre for Braunvieh. Today, however, the self-sufficiency level for Braunvieh breeding material is just shy of 100 %, and Switzerland has even become…
The percentage of concentrates used in the ’dairy cattle and rearing’ enterprise or production branch of organic commercial dairies is estimated on the basis of accounting data. On average this comes to 5 %, with 45 % of farms feeding less than 5 % concentrates. There are very few farms that use no concentrates at…
What is the effect of a low-protein feed supplement on the ammonia emissions from dairy cattle on pasture? To answer this question, the ammonia emissions from two pasture-based feeding systems with dairy cattle were measured and compared between May and October. In the first system (G) the cows fed exclusively on pasture grass, whilst in…
Phosphorus is an essential nutrient for plant growth. Switzerland is reliant upon the import of phosphorus fertilisers, which come from deposit reserves and are increasingly burdened with pollutants. On the other hand, there are hitherto unused phosphorus stocks in sewage sludge and slaughterhouse waste that could completely replace fertiliser imports. Therefore, Switzerland has introduced the…
Between 2015 and 2017, Agroscope tested seven new varieties of xFestulolium braunii (K. Richter) A. Camus and four varieties of brome grass (Bromus spp.) for their agronomic properties in comparative trials at six locations. The characteristics studied were yield, juvenile development, general impression, competitive ability, persistence, resistance to leaf diseases and bacterial wilt, winter hardiness,…
Using cost/performance calculations, the profitability of four para-agricultural activities (contracted work for third parties, direct marketing, tourism and services) is investigated, with labour utilisation, i.e. the resultant hourly wage, serving as a criterion. With a focus on farm activities with a gross performance of between CHF 10,000 and CHF 100,000, there are 2339 observations available…
Arbuscular mycorrhizal fungi (AM fungi) diversity was investigated in 12 selected long-term soil observation sites in the canton of Bern. These consisted of nine soils farmed according to Proof of Ecological Performance (PEP) production guidelines, of which three were natural meadows, three were no-till (NT) or ploughed (PL) arable soils, and three were ploughed arable…
The Swiss agricultural and climate policy- making sector has set itself the target of reducing agricultural greenhouse gas emissions by at least one-third by 2050 compared to 1990’s figures. This target can be achieved via technical measures on the production side and/or by reorganising agricultural structures (area percentages, animal populations). Animal husbandry is responsible for…
In 2016, 75,791 metric tons of fish and seafood were sold in Switzerland, 1,679 metric tons of which were domestically produced. Per capita consumption stood at 9.1 kg and had increased by approximately 60% over the 25 years prior. The present market analysis of the Swiss fish value chain describes the status quo of the…
Since 2014, the Swiss Confederation has made food-supply security payments to ensure the reliable supply of food to the population. At CHF 1.1 billion per annum, these account for a large proportion of direct payments. Agroscope has now tested the effectiveness of this instrument on behalf of the Federal Office for Agriculture, and is proposing…
The tracer ratio method serves to quantify emissions in naturally ventilated animal housing systems. Empa and Agroscope have developed a tracer ratio method with two tracer gases for comparative emission measurements in Agroscope’s experimental dairy housing, with its two spatially separated compartments. In this method, the tracer gases sulphur hexafluoride (SF6) and trifluoromethyl sulphur pentafluoride…
There are three methods available for evaluating sustainability at farm level that were developed in Switzerland: RISE, SMART und SALCAsustain. In this article, the three methods are compared by means of a list of criteria and several concrete examples with the aim of making it easier for readers to decide which tool is best suited…
In Switzerland, biodiversity promotion areas or BPAs (i.e. land under Swiss agri-environment schemes) account for around 15 % of the utilised agricultural area. While the main objective of BPAs is to promote farmland biodiversity, their effectiveness remains limited, in particular as regards the incidence of invertebrates in the lowlands. In this study, the mowing regime…
To improve the underlying data for emission inventories, particulate matter (PM10) emissions were determined for the most common loose-housing system in Switzerland. Emission measurements were conducted in two out of three seasons (summer, transition period, winter) per farm in six naturally ventilated dairy loose-housing systems comprising cubicles, solid floors and an outdoor exercise area. PM10…
Various stakeholders are searching for ways to reduce herbicide use on farms. The implications of such measures, however, are often unknown. This article makes use of a bio-economic model to analyse how plant-protection strategies, yields and contribution margins change in Swiss Extenso winter-wheat cultivation if i) neither glyphosate and ii) nor other herbicides are used.…
Ethologically and ecologically sound production methods, brand awareness and brand credibility are all preconditions for the production of high-quality beef and veal. The market research results presented here show that certain consumer segments more frequently consume Swiss private label branded beef if high production standards in terms of animal welfare, ecology and pasture grazing are…
When people migrate from other cultures to Switzerland, they bring their preferences for the food of their countries of origin. We are what we eat! This article explores the systematic relationship between immigration and food imports for various product categories. The results show that food imports in almost all product categories rise most strongly with…
Grazing differs from mowing in its generally less homogeneous use of forage, and above all in its return of nutrients in the excreta of herbivores. The impact of the type of use (four grazings vs four cuts per year) on the phosphorus (P) and potassium (K) requirements of a grassland in the Swiss Jura was…
The digestibility of the organic matter (DOM) of a forage, whether estimated in vitro via modelling or determined in vivo via experimentation, is a nutritive value considered in isolation. A ration, however, generally consists of a mixture of different forages and concentrates. This trial – consisting of an in vivo study with wethers – studies…
