Description
GlDH, GOT urea and acetone concentrations were estimated in 1254 bovine sera from 150 herds with problems of infertility, metabolic or foot claw diseases. Assossiations of these parameters with the stage of lactation, milk yield and condition of the animal and the whole herd were investigated. The normal range for GlDH was considered to be less than 10 units per litre. Significant correlations between GOT and GlDH and between GlDH and acetone concentrations were observed (r = 0.319 and 0.116). In cases where the blood urea levels exceed 30 mg%, GOT concentrations were significantly increased, but with no detectable changes in GlDH concentrations. The serum concentrations of GlDH were increased only in herds in poor conditions. Animals in good condition did not exhibit increased GlDH concentrations even for those animals which had a relatively high milk yield with a temporary increase in acetone concentration. As a consequence of these studies the Cattle Health Service considers that the serum concentration of GlDH is a late and non-specific metabolic indicator of nutritional insufficiency
