| Abstract | |
Important physiological adaptations occur in the periparturient period; their failure predispose the ewe to metabolic diseases. Knowledge of normal changes makes an early recognition and treatment of mal functions possible and enables prevention of diseases and losses. The biochemical profile of Santa Ines ewes from the 88th day of gestation until 28 days after parturition was evaluated and compared to non pregnant controls. The ewes were divided in groups according to the number of fetuses: G0, non pregnant (10); G1, one (10); G2, two and three fetuses (14). All animals had their heart and respiratory rates as well as their ruminal motility recorded. Serum and plasma was analyzed for the following parameters: glucose, non esterified fatty acids (NEFA), beta hydroxibutyrate (BHB), T3, T4, insulin, glucagon and cortisol activities. Results showed changes in biochemical variables of energy and protein profile during pregnancy and parturition. During the last third of gestation, all ewes showed slightly increased NEFA, T3 and T4 levels when compared to non pregnant ewes. At lambing pregnant ewes, had higher glucose, NEFA and T3 levels. No significant differences on measured parameters comparing simple and multiple gestations were observed. Therefore, when there is adequate adaptation in this period of high metabolic challenge, biochemical parameters considered here are independent of the number of fetuses gestate and can be considered as reference values for a pregnant ewes from the middle third of gestation to first month postnatal period.
