Appropriately increase the ratio of “energy feedâ€, for example, to increase the content of corn, rice, wheat, etc. in the feed, and add 1-2% of animal and vegetable oils to the feed. A better way is to feed a small amount of chopped lard residue every day. Feeding hot feed and hot water powdered feed is adjusted to hard mud with hot water so that the chicken can directly obtain heat from the feed. Use the solar energy conservation site to select the leeward sunny place, depending on the number of laying hens, and build a wall with bricks or mud around the chicken ring. The chicken house and the activity room are divided into two parts. The plastic film is placed on the top of the circle, and the straw is covered on the plastic film at night; ventilation holes are left on the bottom of the activity room wall to prevent oxygen deficiency in the circle. In this way, the solar chicken ring built can have a temperature of 24°C or more during the day in the case of the sun. At the same time, if it is equipped with a 15W lamp, the temperature can still be kept above 15°C. . Zhejiang Industrial Group Co., Ltd. , https://www.xingyeseafood.com
