Milking dairy cows only once daily in late lactation increases the physiological changes in milk composition compared to „normal“ milk. Milk fat and protein contents are considerably higher, coagulation properties are deteriorated, plasminogen and plasmin concentrations are higher and pH is slightly increased. In spite of this critical transformation properties, up to 50% of such milk in processed milk did not lead to a impaired quality of Emmental cheese. It can be concluded that potential problems with the transformation of milk from cows milked only once daily in late lactation can be compensated by mixing it with “normal” milk.
Livestock can convert grassland and by-products into valuable food. But how many animals would Switzerland need if arable land were primarily used for food production instead of animal feed?
Which stakeholders in the dairy sector have an influence on the productive life of dairy cows? Research results from FiBL and Agroscope suggest that broad-based cooperation is needed to create structures for a longer productive life.
Agriculture is aiming to reduce greenhouse gas and ammonia emissions. Agroscope showed that for dairy cattle housing, feed composition plays a role in these emissions as well as wind and temperature.
