Background: The Lori-Bakhtiari sheep breed is one of the most common native breed in the south-western parts of Iran. The peri-parturition period (2 weeks before to, 2 weeks after parturition), is generally of critical importance regarding the health, production and profitability of the ewes. OBJECTIVES: This study was carried out to compare the serum concentrations of glucose, non-esterified fatty acid (NEFA), β-hydroxybutyrate (BHBA), cholesterol, blood urea nitrogen (BUN) and calcium (Ca) during peri-parturition period in 30 single and 30 twin-bearing Lori-Bakhtiari ewes. METHODS: All blood profiles were determined in healthy ewes on days 14, 7 prepartum, and days 7 and 14 postpartum. RESULTS: Serum glucose levels were lower in twin-bearing ewes, compared to single-bearing ewes on prepartum and day 7 after lambing. Serum NEFA, BHBA and cholesterol levels were higher in twin-bearing ewes compared to single-bearing ewes during the peri-parturition period. Lower serum Ca levels were recorded 7 days before and after parturition in twin-bearing ewes, compared to single-bearing ewes. CONCLUSIONS: The results showed that NEFA and BHBA recorded significant (p<0.05) changes during the peri-parturition period in twin-bearing ewes. These significant differences could be related to increased metabolic demands of the fetuses in twin-bearing ewes. | ||
