The MITYBA project tested an integrated dairy cow nutrition approach on 10 Lithuanian dairy farms, covering grassland fertilisation, forage productivity and quality, silage production and the use of extruded linseed press cake in dairy cow diets. In the second stage, cows received 1 kg/day of extruded linseed press cake for 90 days, while milk yield, milk composition and animal health were monitored. Average milk productivity increased by 6%, while milk fat increased from 3.85% to 4.04%. The project provided farmers with farm-tested recommendations for improving forage production and feeding management.
