Determination of degree and relations between derangements of metabolic processes in calves with respiratory syndrome in the milking period was realized in the conditions of the Republic of Belarus. Research results showed that the calves with the respiratory syndrome had expressed metabolic processes disturbances, which were marked in the analyzed biochemical blood indexes (total protein; albumins; urea; creatinine; glucose; cholesterin; triglycerids; bilirubin; ALP; AAT; SGPT; calcium; phosphorous; magnesium; iron; manganese; cobalt; cuprum; zinc). In calves with respiratory syndrome there was noted the increased content of crude protein in blood serum (71,42 +/- 2,57 g/l P less than 0,05), low urea level (3,08 +/- mmol/l). There was the increased level of creatine (574,11 +/- 65,26 mkmol/l; P less than 0,01) and bilirubin (8,11 +/- 1,15 mkmol/l; P less than 0,05). Glucose concentration in blood of diseased calves was at below standard level (3,49 +/- 0,69 mmol/l). Glucose indexes varied and were changing during a day; and depended on muscular activity, intervals between feeding and hormonal regulation. Diseased calves had high cholesterol level in blood serum (4,07 +/- 0,34 mmol/l; P less than 0,05), which was stated in case of liver disease and hypothyroidism. Phosphor level was higher than the standard indexes of healthy calves (2,85 +/- 0,03 and 2,05 +/- 0,05, respectively). Content of magnesium, cobalt and zinc in blood of the diseased calves was lower than in healthy ones. Calves with respiratory pathology had protein, fat, hydro-carbonic and mineral metabolic processes
