| 摘要: |
| 本研究测定了肥育秦川阉牛脂肪组织7种高级脂肪酸的含量,分析了增重剂Rcvalor、脂肪沉积部位及体重的影响。研究发现,埋植Revalor显著提高了秦川阉牛脂肪组织中硬脂酸与亚油酸含量,降低了棕榈酸、棕榈油酸及油酸含量,而对豆蔻酸及豆蔻油酸含量均无显著影响;肾脂的总饱和脂酸含量极显著高于肌肉脂,而后者又显著高于皮下脂;体重对各种脂肪组织的脂酸组成均无明显影响。 |

| Abstract: |
| Contents of 7 fatty acids in adipose tissues of fattened Qin Chuan stetrs were determined, and the effects of growth promotant Revalor, fat depots and liveweight were also analyzed. The results showed that Revalor implantation significantly increased the contents of stearic and linoleic acids, but significantly decreased those of palmitic and oleic acids and had no significant effect on C14 : 0 and C14 : 1 contents. The total saturated fatty acid content was greatly higher in kidney nob fat than that in intramusculor fat, which was much higher than that in subcutanous fat. No evident effect of body weight on fatty acid composition was found. |
