Objective: To determine the concentrations of serum lipids, lipoproteins and - hydroxybutyrate in Iranian native goats in late pregnancy, at parturition and during the post - parturition period. Design: Quasi - experimental time series single group design.
Animals: Fifteen pregnant Iranian native goats without records of twining.
Procedure: Blood samples were taken from the jugular vein of 15 Iranian native goats during 8 weeks pre-partum, at parturition and 8 weeks post-partum. The measured parameters were cholesterol, triglyceride, total lipid, high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL) and ? ¬hydroxybutyrate.
Statistical analysis: The data were analysed by repeated measure of analysis of variance (Time series). All values were expressed as mean± standard error with P< 0.05.
Results: Pregnancy had a significant effect (P<0.05) on the serum cholesterol, triglyceride, VLDL- cholesterol and LDL-cholesterol of the Iranian native goats, as with progression in the pregnancy period there was an increase in the cholesterol and LDL- cholesterol
concentrations and a decrease in the triglyceride and VLDL¬
cholesterol concentrations. Lactation had a significant effect on the serum lipids and lipoproteins of Iranian native goats as with progression in the lactation period there was an increase in the cholesterol, triglyceride, LDL- cholesterol and VLDL- cholesterol concentrations.
Conclusion: During the periparturient period of Iranian native goats, variations of serum lipids and lipoproteins should be taken into consideration in reaching a more precise diagnosis of metabolic diseases. In these times, the variations of serum ? -hydroxybutyrate were not significant and hence neglectable in assessing the disease
