The estimation of the metabolic profile of blood serum of purebred and crossbred young sheep in the context of intensity of growth. The object of the research was five-month-old purebred bright Roma breed (P) and crossbred, received in the result of crossing ewes of the Pechora breed groups sheep breed ostfriz (1/2П х 1/2О), grown under the same conditions feeding and maintenance of the Pechora experimental station. For the experience was developed four groups of calves by 5 goals each: I (1/2П х 1/2О) is a high-energy growth; II (1/2П х 1/2О) – low; III (R) – high IV and (R) – low energy growth. Group bright low energy growth taken for control. Metabolic profile sky growing bright was characterized by the following features: the level of albumin over 45% of the total protein; A/G ratio approaches one; the average and below average (3,3 to 5,0 mmol/l) within normal level of urea; glucose + cholesterol more than five; the de Ritis coefficient is 1,8-2,2; high within the normal values of calcium, phosphorus and alkaline phosphatase. Metabolic profile slow growing bright: the level of albumin less than 45% of the total protein; A/G ratio is less than 0,85; glucose and glucose + cholesterol – the lower limit of normal; the de Ritis coefficient above 2,2. Significant differences in favor of the growing bright in intensity of protein, carbohydrate and other exchanges allow the use of biochemical parameters of blood on the early stages of ontogenesis as a marker signs to predict the growth and the assessment of adaptation to the conditions of detention.
