This work aimed at evaluating the effects of injected copper supplementation on the occurrence of hypochromic anaemia in dairy cows 30 days before parturition. At the beginning and on the 20th day of the experiment, experimental animals were treated with Copperdep inj. at a dose of 1 mg Cu/kg b.w. This preparation is tested before its commercial production. Increases in serum copper levels were recorded on the 4th day after administration and significant differences between the experimental and control groups persisted up to the 15th day after calving (p 0.001). In the experimental group, an increase in serum Fe concentration was observed from the 7th day after the treatment. Administration of the preparation to pregnant cows suffering from hypocupraemia, sideropenia, and hypochromic anaemia resulted in an improvement in serum levels of Cu, as well as Fe, and values of Er, Hb, and PCV. Moreover, in the experimental cows a gradual restoration of hair and mucosal membranes was observed from the 20th day after the treatment
