Evaluation of lipid profiles and thyroid hormones in Raini Cashmere goats in peripartum.

Raini Cashmere goat is one of the most important breeds of goats in Iran, which has a high economic value in the world markets due to its high-quality fluff. It is mostly found in the southeast of Iran, especially in Kerman province where there are about three million head of this breeds. The present study aimed to evaluate serum lipids profile and thyroid hormones in the Raini Cashmere goat in peripartum for better identification of this breed. Blood samples were taken from the jugular vein of six adult Raini Cashmere goats and sent to the laboratory for evaluation of cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, very low-density lipoprotein, serum glucose, and thyroid hormones. The results showed that glucose, HDL, and LDL levels increased 2 to 3 weeks before parturition and decreased after parturition. However, the triglyceride, cholesterol, T3, and T4 concentrations decreased before parturition and increased after parturition. According to the results, it was concluded that the glucose concentration increases due to the high need of the mother for nutrients to grow the fetus too. Other factors such as triglycerides and cholesterol decrease due to the absorption of fatty acids by the liver and the storage of triglycerides and cholesterol. In addition, the negative energy balance preceding parturition is associated with a reduction in the T3 and T4 levels. [ABSTRACT FROM AUTHOR]
