用含有0,500,750,1000,2000或4000PPm的铅(PbAc_2·3HpO)的饲料喂养Arbor Acre broiler种小鸡21天。不同的铅水平饲料分6组,每组小鸡10支。在第21每个铅水平饲料组处死8支,用气一液相色谱仪测定每支鸡肝脏内脂肪酸的组分,随着食铅水平的增加,16:1脂肪酸的浓度下降,(前一数字代表碳数,后一数字代表双键数,即含有16个碳原子和1个双键的脂肪酸)18:0及20:4脂肪酸浓度上升。在所有铅水平饲料
Arbor Acre broiler chicks were fed for 21 days with a feed containing 0, 500, 750, 1000, 2000 or 4000 PPm of lead (PbAc 2 .3HpO). Different levels of lead feed 6 groups, 10 chickens in each group. Eight pigs were sacrificed in the 21st lead-level feed group, and the fatty acids in each chicken liver were determined by gas-liquid chromatography. As the lead level increased, the concentration of 16: 1 fatty acids decreased, The numbers represent the number of carbons, the latter number representing the number of double bonds, ie the fatty acids containing 16 carbon atoms and one double bond.) The 18: 0 and 20: 4 fatty acid concentrations increase. Feed at all lead levels
