[Comparative observations of the results from community studies of the precision of the energy requirements of young female cattle].
Institutes from 4 CMEA countries took part in coordinated joint studies for a precise determination of the energy requirement of young female cattle. A comparative description of the results is given. The most important conclusion is that the energy requirement of young female cattle of various dairy cattle genotypes can be described with sufficient accuracy according to the net energy fattening (NEFcattle) requirement equation derived in the GDR if the keeping conditions are taken into account.
