摘　　要：　湘黄鸡散养时进入脱温期的日龄,因全年中各季的气温不同,而具有很大差异。研究得出;一年中的7月中旬至8月上旬气温最高时,鸡群在7d左右即可脱温,脱温最早。而在12月中旬至2月上旬气温最低时,则要68d以上才能进行脱温,脱温最晚。The time of stopping heat supplication is different because of the different daily temperature change at different seasons for scatter-feeding of Xianghuang Chicken. The research result showed: The chicken could stop heat supplication at the 7th day, the earliest time in one year from the mid of July to the earlier days of Aug. From the mid of Dec to the earlier days of Feb, the daily temperature is the lowest, the stopping heat supplication days should be in its 68 ds, that is the latest time.
