饲料磷脂水平对巴丁鱼(Pangasius sutchi)鳃Na+-K+-ATPase 活性及细胞膜脂肪酸组成的影响
Effects of dietary phospholipid on Na+-K+-ATPase activities and cell membrane fatty acid composition in gill of catfish (Pangasius sutchi)
摘要
Abstract
The aim of this study was to determine the effects of dietary phospholipid on Na+-K+-ATPase activities and cell membrane fatty acid composition in the gill of catfish (Pangasius sutchi). 900 healthy catfish (1.4±0.08g of average weight) were randomly divided into five groups. Dietary phospholipid level of group PLO was 0％, and 1％, 2％, 3％, 4％ for group PL1, group PL2, group PL3, group PL4, respectively. The experiment lasted for 56 days. The results showed that the Na+-K+-ATPase activities in gill decreased gradually with the increase of the dietary phospholipid level (P＜0.05). Cell membrane fatty acid composition was affected significantly by dietary phospholipids. The content of saturated fatty acids and monounsaturated fatty acids of group PLO was highest (P＜0.05), however, it had the lowest content of highly unsaturated fatty acids (P＜0.05). The content of polyunsaturated fatty acids in group 3 was higher than that in group 0 and group 1 (P＜ 0.05). The results indicate that there is obvious compensation effect on Na+-K+-ATPase activity with phospholipids content changes in gills of catfish (Pangasius sutchi) and the increase of ∑HUFA and ∑PUFA is necessary for gill cell membrane to maintain and perform normal physiological function.关键词
