摘　　要：以1日龄、健壮的艾维茵(avian)肉仔鸡630只(公母各半)为试验动物,以自行配制的复合维生素、复合微量元素和复合生物活性添加剂为试验因素,采用3因子5水平二次回归通用旋转组合设计,平分成21个组(其中设1个对照组),得到15种施用水平组合及其15种试验日粮,进行49d饲养试验。结果表明:采食2号日粮的第2组试鸡胸肌中多不饱和脂肪酸含量最高,均值为22.10%;饱和脂肪酸含量较低,均值为26.09%;分别比增设的对照组优8.59%和16.27%,差异极显著(P<0.01)。试验条件下,肉鸡胸肌中饱和脂肪酸含量和不饱和脂肪酸含量与3种复合添加剂施用水平呈极显著的回归关系,对二次回归数学模型寻优得出各复合添加剂(或其各个活性成分)在肉鸡饲粮中的最佳添加量分别是:复合维生素2234.51mg/kg(E340.53、C378.35、A5675.38、H0.57)、复合微量元素4211.70mg/kg(Fe113.51、Cu132.43、Mn170.26、Cr1.14、Zn208.10、Se0.281)、复合生物活性物质1099.95mg/kg(甜菜碱1054.11、大蒜素24.33)。By means of three-factor, five-level, quadratic regression general rotational combination design, 630 one-day-old healthy avian broilers were divided into 21 groups （one control and 20 treatments） randomly. Multi-vitamin, compound trace elements and compound active additive are the experimental factors. 20 out of 21 groups were fed to fifteen kinds of experimental diets, while the rest one was fed to normally diet as control. After 49days experiment,the results showed that polyunsaturated fatty acids contents of chest muscle in broilers in group 2 fed on diet No 2 was the highest ,the mean was 22.10%. and saturated fatty acids contents was lower, the mean was 26.09%. Which were better than the figures of the control group by 8.59% and 16.27%,respectively （P〈0.01）. The results obtained suggested that the supplement levels of three compound additives are closely related with the saturated fatty acids and un- saturated fatty acids contents in chest muscle in broilers. In the condition of this experiment, the optimal level of these compound additives in the diet is 2 23451 mg/kg multi-vitamin （E 34053,C 378.35 ,A 5 675.38, H 0.57）;4 211.70mg/kg compound trace elements（Fe 113.51 ,Cu 132.43,Mn 170.26,Cr 1.14,Zn 208.10,Se 0.281）, and 1 099.95mg/kg compound active additive（Betaine 1 054.11, allitridum 24.33）.
