Extract

In a previous experiment with dairy cows at this Institute, in which fodder beet was included as a third component of the diet along with grass silage and concentrate, fodder beet considerably increased metabolisable energy intake (MEI), but there was little effect on milk yield (unpublished data). The main objectives of the present study were to examine the effects of including fodder beet versus concentrate in a grass silage diet, on milk production, digestibility of nutrients and the utilization of nitrogen (N) and energy at equal ME intake in lactating dairy cattle.
