Ten Dohne merino wethers with an average mass of 50 kg, were used to study differencesin ruminal VFA production rates, whole body kinetics of VFA, glucose and FFA as well as blood hormone concentrations when fed a high- or a…
Genetic variation within and differentiation between juvenile and adult elephants (Loxodonta africana) culled during April 1992 and May 1993 were compared to determine the effect of culling on successive generations. Gene products of 25 protein-coding loci were examined by horizontal…
