Effects of very low quantities of dietary concentrates on performance and health of high yielding dairy cows
Landwirtschaft Schweiz 2(9): 508-512
In a 2-year experiment 20 and and 24 dairy cows were given concentrates 150 kg mainly in the first 2 months of lactation. Basal diet was dried fodder plus fodder beet 6 kg DM or maize silage. Diet during the summer was green fodder, maize silage 3.5-4.0 kg DM and half-day grazing. Decreasing concentrates increased intake of the basal diet significantly. Average milk production was 7240 and 6730 kg with an average concentrate supplement of 121 and 107 kg.
