| 摘要: |
| 用气相色谱技术测定了长白猪皮下及肌间脂肪中8种脂肪酸的含量,分析了埋植Anabolic的影响。发现埋植Anabolic显著降低了豆蔻酸、硬脂酸和饱和脂肪酸总量(SFA)的比例,提高了棕榈酸以及不饱和脂肪酸总量(UFA)的比例。Anabolic的A,B两种剂型比较,以B剂型的作用较强。此外,皮下脂肪中未测出棕榈油酸,没有发现肌间脂肪中有亚麻酸和花生烯酸;前者富含棕榈酸、亚油酸、UFA和多聚不饱和脂肪酸(PUFA),后者豆蔻酸和SFA较多。肌间脂肪的脂肪酸易受Anabolic的影响。 |

| Abstract: |
| Contents of 8 fatty acids in adipose tissues of fattened Landrace pigs were determined using gas chromatography techniques, and the effects of the growth promotant agent-Anabolic and adipose tissue on them were analyzed. It was found that the Anabolic implantation significantly (P<0.01, P<0.05) decreased the percentages of myristic acid, stearic acid and total saturated fatty acid (SFA), and increased the percentages of palmitic acid and total unsaturated fatty acids (UFA). Compared with A type agent of the Anabolic, B type agent had stronger effect. In addition, no palmitc acid was found in subcutanous fat. Also, linolenates and arachidonic acid were not detected in intramuscular fat. The former is rich in palmitoleatie acid, linolelic acid, UFA and PUPA, but the latter has more myristic acid and SFA. The fatty acid composition in intramuscular fat is easy to be affected by Anabolic. |
