[Follow-up studies on the behavior of mineral metabolic parameters with particular reference to the degree of skeletal minearlization in the milch cow in the period 4 weeks ante- to 16 weeks postpartum].

The following parameters were tested in clinically intact dairy cows and those afflicted with parturitional paresis, over a period from four weeks before to 16 weeks after parturition: calcium, inorganic phosphate (PA), magnesium, alkaline phosphatase (AP), glucose, total protein, mineral mass/fat-free dry matter (A/FFT), mineral mass/volume of fresh skeletal bioptate (A/V). Literature data regarding the behaviour patterns of Ca, PA, Mg, AP, and glucose were confirmed. The dynamics of physiological mineral catabolism and mineral anabolism were expressed by the A/V changes more clearly than they had been reflected in A/FFT. The criterion A/V should be included as a function of age in the spectrum of parameters of metabolic monitoring.
