Feed characteristics can influence behaviour in laying hens. Twelve hens (ISA-Brown, 56th to 68t th week of age) were used to analyse feeding patterns. Three diets, different in structure (fine vs. coarse particle size distribution) and composition (isoenergetic replacement of starch by fibre and fat) were tested. Diurnal distributions of number, size and duration of meals, feed consumption and feeding time per hour were registered . Fine structured feed resulted in Ionger feeding times per day than coarse diets. Feed composition had less influence on feeding patterns. Feed with fine particle size distribution can be recommended to reduce occurrence of feather pecking because of increased occupation by feeding.
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.
