摘要:

The effect of different iron concentrations in the milk replacer on the development of iron deficiency anaemia during a fattening period of 28 weeks was studied in three groups of 14 calves. The iron contents in the milk replacer differed during the first seven weeks: 60, 100 and 150 mg Fe/kg in groups A, B and C, respectively. In all three groups blood haemoglobin, mean corpuscular volume, plasma iron concentration and saturation decreased during the fattening period whereas the total ironbinding capacity increased At week 7, liver iron concentrations were high with a large individual variation [A: 201 (61–706), B: 99 (47–129), C: 296 (77‐ 1572) μg/g dry matter]. During the fattening period, liver iron concentrations decreased with the lowest values at week 25 [A: 54 (34–82), B: 55 (44–83), C: 57 (42–79) μg/g dry matter]. Muscle iron concentrations decreased between week 7 and 19. Except plasma iron and saturation in group C, no differences in haematological and tissue iron variables were found throughout the fattening period in spite of different iron contents in the milk replacer during the first seven weeks.
