The experiment was conducted to investigate the effect of heating by briquet stove on the performance of the laying pullets (W.L.×W.L., W.L.×N.H., W.L.×B.P.) in winter night. The laying cage house was divided into two parts, one part (10.8×4.0m) was covered with board and glass window and heated by two briquet stoves in night. Another part (7.2×4.0m) was not heated and covered with polyethylene membrane. Average minimum temperature in the heated part was 3.2°C higher than that in the unheated part and average hours of ambient temperature below 5°C in a day in the heated part became shorter than unheated part (Table 1). In the heated part, egg production did not increase and feed consumption decreased, but feed conversion did not necessarily become better (Table 2).
