Abstract :

Assessed were changes in selected biochemical parameters taking place during different stages of
pregnancy, post-partum, lactation and dry period in ewes. The observations were conducted on 10
clinically healthy Comisana ewes kept on one farm. Blood samples were withdrawn once before
the morning feeding during dioestrus phase before pregnancy, and then on week 4, 11 and 18 of
pregnancy, week 2 post-partum, week 5, 15 and 25 of lactation and finally once in a dry period (week 32). Blood serum total protein as well as serum albumin increased significantly during pregnancy compared to dioestrus phase. Compared to dioestrus, a significant increase during late gestation and a significant decrease during dry period was shown in blood urea. Total blood lipids showed a significant increase during pregnancy, post-partum and early lactation compared to dioestrus, while total cholesterol and triglycerides showed the opposite trend. The study showed marked changes in certain biochemical parameters of sheep blood serum during late pregnancy, post-partum, lactation and dry period.
