Meat type chickens were fed a commercial mixture of polychlorinated biphenyl (PCB), Aroclor 1254, at 10 ppm for 14 days, then treated for 21 days to hasten the withdrawal of PCB with either mineral oil (MO), petroleum jelly (PJ), propylene glycol (PG), or colestipol (CO) at 5% of the diet, or at 10% of the diet when restricted to 50% of control intake (50% FR). Whole carcass analyses for PCB revealed that MO + 50% FR reduced PCB to 1.91 mg/bird, or 32% of the body burden (5.96 mg) in nontreated chickens previously fed PCB, whereas those restricted in feed intake by 50% (50% FR) had almost no change (6.44 mg/bird) in body burdens. The PJ, PG, and CO in combination with 50% FR reduced body burdens of PCB to 47, 57, and 77%, respectively, of the control value. When treated with MO, PJ, PG, or CO alone (no 50% FR), chickens had body burdens reduced to only 67 to 90% of control, depending on th compound. Thus, feed restriction was necessary for the MO and PJ to have their greatest effect. Carcass lipid values and body weight gains were markedly reduced by the feed restriction. The CO reduced carcass lipid in nonrestricted chickens by 30%.
肉用型鸡被喂食含有10 ppm多氯联苯（PCB）商品混合物Aroclor 1254，持续14天，然后用矿物油（MO）、凡士林（PJ）、丙二醇（PG）或考来烯胺（CO）进行为期21天的处理，以加速PCB的排出，这些物质在饲料中的添加比例为5%，当采食量限制为对照采食量的50%（50%FR）时添加比例为10%。对整个鸡体进行PCB分析发现，MO + 50%FR使PCB含量降至1.91毫克/只，即先前喂食PCB的未处理鸡体负荷（5.96毫克）的32%，而采食量限制50%（50%FR）的鸡体负荷几乎没有变化（6.44毫克/只）。PJ、PG和CO与50%FR联合使用时，使PCB的鸡体负荷分别降至对照值的47%、57%和77%。当单独用MO、PJ、PG或CO处理（无50%FR）时，鸡的体负荷仅降至对照值的67%至90%，具体取决于化合物。因此，采食量限制对于MO和PJ发挥最大效果是必要的。采食量限制显著降低了鸡体脂肪值和体重增加。CO使未限制采食量的鸡的体脂肪减少了30%。
