在春、冬育雏季节,经常停电或无电,使育雏的温度得不到保证,影响了养禽业的发展。为此,我们开展了锯末育雏桶育雏试验。育雏桶系用铁皮制做直径60厘米、高为100厘米的圆桶,并相应做个上盖。在盖的中央钻个直径10～15厘米的孔,并附设活动片(见图),可以开闭。圆桶底部开通风孔,安上活动风门开关,用以调节室温;同时在底部顺通风孔连接一根直径10厘米,长与圆桶直径相等的铁管,管中央开个10厘米的口,以便中心通风孔的铁管插入此处.最后,在圆桶上方(离炉盖
In the spring and winter brooding season, often blackouts or no electricity, the brooding temperature can not be guaranteed, affecting the development of poultry industry. To this end, we conducted a sawdust brood barrel brooder test. Brood barrels made of metal with a diameter of 60 cm, height of 100 cm drum, and the corresponding to be a cover. Drill in the center of the lid a diameter of 10 to 15 cm hole, and attached to the activity film (see photo), you can open and close. At the bottom of the vent connected to a diameter of 10 cm, the same diameter and length of the tube drum, the center of the tube to open a 10 cm of the mouth, So that the central vent of the iron pipe inserted here Finally, above the drum (away from the lid
