Selected indicators for the metabolic profile of blood plasma in 22 Aberdeen Angus bulls reared by the extensive method were monitored during postnatal development (from 4 to 564 days of age), including total proteins, albumin, urea, creatinine, glucose, cholesterol, triacylglycerols, bilirubin, alkaline phosphatase, alanine transaminase, aspartate transaminase, tyroxin, triiodothyronine, calcium, inorganic phosphorus, magnesium, potassium, sodium, chlorides, copper, zinc and iron. In assessing the relationship of age to the indicators of the internal environment, values of correlation coefficients for total proteins (r = –0.70; p < 0.01), albumin (r = –0.56; p < 0.01), urea (r = –0.73; p < 0.01), glucose (r = –0.38; p < 0.01) and triiodothyronine (r = –0.82; p < 0.01) were established. Significant relationships were shown between the temperature of the external environment and the amount of total proteins (r = –0.38; p < 0.01), urea concentration (r = –0.41; p < 0.01), ALP (r = 0.58; p < 0.01) and ALT (r = 0.45; p < 0.01) activity. Temperature also showed a significant impact on the concentration of P (r = 0.57; p < 0.01), K (r = –0.69; p < 0.01) and Zn (r = 0.33; p < 0.01). The work yields important information on changes in the indicators of the metabolic profile of the blood plasma of bulls during postnatal development under defined nutritional and temperature conditions that can be used as reference values for evaluating health status as well as nutrition level.
