The changes in some biochemical and haematological parameters in three cows with post-parturient haemoglobinuria were described. The animals were 4, 6, and 7 years of age. These cows had calved in the autumn. Post-parturient haemoglobinuria in the cattle occurred at a post-partum of about 3 weeks. The cows received phosphorus supplementation and supportive treatment. The mean serum phosphorus level in the affected cows was significantly lower compared with healthy cows. In the meantime, the blood RBC, PCV, MCHC, and Hb values were also significantly lower compared with healthy cows. In conclusion, the deficiency of phosphorus could be responsible for the development of post-parturient haemoglobinuria in the cows.

The objective of this study was to investigate the serum concentrations of iron, manganese, cobalt, copper, zinc, and copper/zinc ratio in Downer cows. The study was performed on 20 recumbent Downer cows and 20 healthy cows. The serum concentrations of iron (P=0.002) and copper (P=0.035) were lower in Downer cows compared with the healthy cows. Serum zinc concentrations, although not significantly (P=0.162), were also lower in Downer cows compared with the healthy cows. Cows with Downer syndrome had greater concentrations of serum AST (P<0.001), LDH (P=0.003), and CK (P<0.001). Other biochemical parameters remained unchanged. RBC (P=0.026), Hb (P=0.029), and MCV (P<0.001) in cows with Downer syndrome had lower values compared with those of healthy ones. However, WBC in cows with Downer syndrome had greater values (P<0.00l) compared with those of healthy ones. Other haematological parameters remained similar between Downer cows and healthy cows. It was concluded that serum iron and copper concentrations may play an important role for the aetiology and/or pathogenesis of Downer cows. These elements may be supplemented for the prevention and therapy of recumbency in cows.
