选用640只雪峰乌骨鸡,分别饲喂添加不同水平(0.1,0.3,0.5mg/kg)的甲状腺激素(T3);5～8周龄分成2个组,一组停止添加T3,另一组继续添加T3,以研究甲状腺激素(T3)对雪峰乌鸡蛋白质沉积是否具有后续作用.结果表明:(1)甲状腺激素在2周龄以前可显著(P

0,0.1,0.3 or 0.5mgT3/kg was added to diet to determine . The whole period was separated and later（5 - 8week） period. At 5thweek, every replicate was separated to two group again ,one fed basal diet, another continue added T3 to basic diet, to deter- mine the carry - over effect of thyroid on black - bone chickens. The growth performance ,protein retention and thyroid homone was examed in every 2 weeks. The results showed that： 1. Dietary T3 supplementation stimulate growth of black -bone chickens before 6th - week, and optimal dose is 0. 1mg...
