Resumo: | The clinical picture of sulphur (S) deficiency is described by the first time in Brazilian dairy calves. Twelve crossbred six-month-old weaned dairy calves, reared on pasture of S-deficient Brachiaria decumbens, were used. The calves were randomly assigned in two groups of six calves each to verify the influence of S supplementation on some clinical and serum biochemical variables. All animals were fed a basal-supplement mix containing macro and microlements, urea and ground corn grain added (41gS/kg) or not of S (elemental S; 1g S/kg), for six months. At the end of the experiment, the S-supplemented calves had higher mean body weight (p &lt; 0.01), body condition score (p &lt; 0.016), serum inorganic sulphate concentration (p &lt; 0.001) and serum albumin concentration (p &lt; 0.01) than the S-deficient calves. The unsupplemented dairy calves exhibited loss of body condition, retarded growth, weight loss and slight apathy.
