Abstract

The objective of this study was to evaluate effects of Artemisia annua extract (AAE) on fatty acid contents, i.e. conjugated linoleic acid (CLA) content, in external pudendal arterial and venous blood in the mammary gland of dairy goats. Nine healthy lactating Guanzhong dairy goats with the body weight of (38±3) kg were randomly divided into 3 groups with 3 goats in each group. Goats in control group, group Ⅰ and Ⅱ were supplemented with 0, 7.26 and 12.10 g/d AAE, respectively. After 30 d pretrial period, blood samples were collected from external pudendal artery and vein in the mammary gland after 0, 3, 6 and 9 h of feeding for analysis of fatty acid composition. The results showed as follows: In the mammary gland, c9 C18∶ 1 and CLA could be synthesized, while C18∶ 2, C18∶ 3, t11 C18∶ 1 and C18∶ 0 could not be synthesized; supplementation of AAE increased contents of t11 C18∶ 1, CLA and c9 C18∶ 1, but decreased the content of C18∶ 2. The results indicate that AAE has a stimulant effect on the synthesis of CLA and its precursor.
