Abstract: 

BACKGROUND: Pregnancy and parturition are the important physiological conditions that could affect the body metabolism in ruminants.
OBJECTIVES: The present experiment was carried out to investigate the variations of thyroid hormones and metabolite levels during pre-conception, pregnancy months and post parturition in Arabic ewes.
METHODS: Estrus synchronization and natural mating were done in 20 healthy Arabic ewes with the ages of 3 to 5 years and they were reared under the same breeding and feeding conditions. Blood samples were taken before gestation, consecutive months of pregnancy and 45 days after delivery and blood sera levels of thyroid hormones and metabolites were determined. Data were analyzed using the SAS software in a completely randomized design by Proc Mixed.
RESULTS: The blood sera concentration of T3 before the pregnancy was lower than that in post parturition (P<0.05). The amount of T4 in the last month of pregnancy was the lowest (P<0.05). T3/T4 ratio in various periods was not significantly different (P>0.05). Blood sera glucose in pre pregnancy was higher than its amount in gestation months and post parturition (P<0.05). Triglyceride concentration in the last month of pregnancy was the highest (P<0.05). Total protein concentration in the last month of pregnancy showed a significant decrease in comparison with other months of the pregnancy and before pregnancy (P<0.05). Albumin concentration of the blood sera was not affected by the time intervals of the study (P>0.05). Sera globulin concentration in the fourth month of pregnancy reached the highest value when compared to pre pregnancy and post parturition (P<0.05).
CONCLUSIONS: The results of this study showed that the levels of thyroid hormones and some blood serum parameters of Arabic ewe in pre-conception, months of pregnancy and post parturition periods were different.
