[The development of iron and copper concentrations in blood plasma of calves in the first days and weeks of life, equally a contribution to the larvaceous neonatal iron deficiency anemia].

摘要: Newly born calves (n = 93) were examined to determine the iron and copper values in blood plasma. The investigation was divided into two sections: 1. Chronic measuring of parameters live-born until sixth week 48). 2. Short-time examination newly with different vitality figures/levels second day life 45). Iron determined by means an inductively-coupled-plasma emissions-spectral analysis (ICP). In case a normal birth criteria are plasma concentration 27.7 +/- 9.6 mumol/l 4.8 1.7 copper. During first few hours drops considerably significantly (p less than or equal 0.01) rises again before week. There is short period considerable depression concentration. values, contrast, increase linearly 0.001) form onwards end week, then remaining on high level. dynamic curve influence race/breed also evident. Calves race DFV have higher level DSB DRB at life. About fifth (18.8) test animals part already had hidden sideropenia (16.1 1.9 mumol/l) when they born. Their developed only slowly.(ABSTRACT TRUNCATED AT 250 WORDS)
