6 duplicate floor pens with 20-day-old commercial broiler chicks each, were fed practical-type broiler diet with maize-palm kernel meal, supplemented with graded levels of biotin so that the rations had 40, 80, 120, 160, 200, and 240 micrograms of the vitamin per kg of feed. This treatment was maintained for 6 weeks. Estimation of the body weight, feed intake, blood glucose concentration, and lipid contents of liver, kidney and blood showed that dietary biotin of 120 micrograms/kg feed is a minimum requirement. 160 micrograms/kg feed was required for the prevention of dermatitis, mortality due to fatty liver and kidney syndrome (FLKS) and leg deformities.
6个重复栏位，每个栏位饲养20日龄的商品肉鸡，饲喂含玉米-棕榈仁粕的实用型肉鸡日粮，并添加不同水平的生物素，使日粮每千克饲料中维生素含量分别为40、80、120、160、200和240微克。该处理持续6周。对体重、采食量、血糖浓度以及肝脏、肾脏和血液中的脂质含量进行评估，结果表明每千克饲料中120微克的日粮生物素是最低需求量。预防皮炎、脂肪肝和肾综合征（FLKS）导致的死亡率以及腿部畸形需要每千克饲料160微克的生物素。
