TI  - Impact of a trace element supplementation programme on health and performance of 
      cross-breed (Bos indicus x Bos taurus) dairy cattle under tropical farming 
      conditions: a double-blinded randomized field trial.

AB  - Small-scale urban dairy farms (n = 16) in and around Jimma, Ethiopia with 
      cross-bred (Bos indicus x Bos taurus) cows were enrolled in a double-blinded 
      intervention study to investigate the effect of a trace element supplementation 
      programme on trace element status and milk concentrations as well as performance 
      [body condition score (BCS), milk yield, leptin], milk composition, antioxidant 
      status (ferric-reducing ability of plasma (FRAP), thiobarbituric acid-reactive 
      substances (TBARS)], blood biochemistry, serum proteins and immune response 
      (antibody titre upon rabies vaccination). The farms were allocated to a (1) 
      placebo or (2) Cu, Zn, Se, Co and I supplementation treatment for 150 d. On days 
      0 and 120, four lactating cows per farm were sampled for milk and plasma, and on 
      day 150 for serum, following primo-vaccination. Cu deficiency was present in 17% 
      and marginal Se deficiency in 30% of initially sampled cows, while no Zn shortage 
      was detected. Over 120 days, trace element supplementation caused a bigger 
      increase in plasma Se and Cu concentrations, but also a larger decrease of plasma 
      Fe concentrations. A larger increase in milk Se concentrations was observed in 
      the supplemented group, whereas none of the other elements were affected. BCS 
      decreased more over time in the supplemented group. None of the other parameters 
      of performance and antioxidant status nor milk composition or blood biochemistry 
      was affected by treatment. Antibody response to rabies vaccination did not differ 
      between groups, whereas alpha1-globulins tended to be lower and beta-globulins tended to 
      be higher in the supplemented group. In conclusion, despite improved Cu and Se 
      status and Se concentrations in milk, cows on tropical urban dairy farms did not 
      seem to benefit from trace element supplementation, with respect to the 
      parameters investigated.
