Sažetak
Properties of bone tissue adapt to environmental conditions by process of bone remodeling during the lifetime of an individual as well as by the process of evolution for many generations. Over the life of the cow there are two important metabolically intense events dominated by absorption processes, to which bone tissue is constantly adapting: fetal development and milk production. This study was carried out on 13 cows of Simmental breed. Blood samples were collected from jugular vein 6, 12, 48 hours and 7 days after birth. Serum concentrations of parathyroid hormone (PTH) and calcium and activity of bone-specific alkaline phosphatase (BALP) were determined. Concentration of PTH was significantly higher 7 days after birth compared with values measured 12 hours after birth (p<0.05). The BALP activity was significantly higher 6 hours and 7 days after birth compared with that 12 hours after birth (p<0.05). Concentration of calcium showed no significant variations during study. In cows, positive correlation was observed between calcium concentration and BALP activity 7 days after birth (r=0.79 ; p<0.01). The changes observed in cow’s serum indicate that the bone metabolism of cows in the early postpartum period is very intense and directed to the remodeling of a bone tissue, due to increased need for calcium for milk production.
