In a feeding trial with 58 dairy cows in different stages of lactation, including 14 primiparous animals, the effects of using a high proportion of rapeseed cake (70 %) in a protein supplement were studied in comparison with a concentrate based on soybean meal and sunflower seeds and meal. The basal ration was restricted hay and fodder beets and maize silage fed ad libitum. No significant effect on milk production and composition was observed, but daily intake of maize silage was 1.5 kg DM higher during the first third of lactation. The supplemental intake of plant lipids did not influence the fatty acid composition of the milk in the 9th week of lactation.
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.
