White clover and smooth-stalked meadow grass make a significant contribution to persistence and grazeability in high-yielding fodder-production mixtures. Based on the 2022 to 2024 variety trials, Agroscope can now recommend two new varieties for each of these species.

If we systematically reduce inefficiencies in the food system—such as the heavy use of cropland-based feed, concentrate feed for cattle, and avoidable food waste—we can achieve much higher self-sufficiency while lowering environmental impacts.

The use of vegetable fibre can reduce plant-protection product residues by up to 80% in white musts, with a more limited effect in red musts.. The method can be applied in cellar, as a complement to the responsible use of products in the vineyard.

Agroscope and its Italian counterpart CREA (Consiglio per la ricerca in agricoltura e l’analisi dell’economia agraria) have described the new bacterial species Clostridium caseinilyticum sp. nov., isolated from cheese with the ‘putrificus’ quality defect and from silage. The study sheds light on potential causes and can contribute to the development of preventive measures.
