Abstract:

Concentrations of blood lipids and some lipoproteins were investigated in normal female Baladi goats during late pregnancy, parturition and onset of lactation as well as in their newborn kids during the first two weeks of life. A total number of 60 herparinized blood samples was collected from does at 4, 3, 2 and 1 weeks pre-partum, day of parturition and at 1, 2, 3 and 4 weeks postpartum. In addition, blood samples were also collected from their newborn kids during the first two weeks of life (day of birth, 1 and 2 weeks of age). Plasma was separated and analyzed for concentration of total lipid, total cholesterol, triacylglycerols, phospholipids, non esterified fatty acids (NEFA) and some lipoproteins as high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C). The obtained results revealed that there was a significant decrease in plasma level of total lipids at one week after parturition. Plasma level of triaclyglycerols was significantly higher at 4, 3 and 2 weeks before parturition. This increase became very highly significant at one week before parturition. Meanwhile, plasma phospholipid concentrations showed a significant decrease at 3 weeks before parturition, followed by an significant increase at 2 and 3 weeks after parturition and highly significant increase at 4 weeks after parturition. The concentration of plasma NEFA showed a significant increase at 4 weeks before parturition followed by a very highly significant increase at 2 and 1 week before parturition. On the other hand plasma NEFA was non detected at 2, 3 and 4 weeks post-partum when compared with the value reported at day of parturition. Regarding plasma lipoprotein concentrations the obtained results showed that there was a significant increase in plasma HDL-C level at 2 and 3 weeks after parturition, followed by a very highly significant decrease at the fourth week post-partum. However, plasma LDL-C level showed a significant decrease at 3, 2 and 1 weeks before parturition, followed by a further highly significant decrease at 1 and 2 weeks post-partum. In newborn kids plasma concentrations of total lipids, total cholesterol, phospholipids, HDL-C and LDL-C were very markedly increased at 1 and 2 weeks of age. However, plasma triacylglycerol concentrations showed a highly significant decrease at 1 and 2 weeks of age. The concentration of plasma NEFA showed a very highly significant decrease at 2 weeks of age, whereas, at one week of age plasma NEFA were not detected in comparison with first day of life.
