Rapid feeding and management of native chicken

1. The structure of chicken coop can be reconstructed from old house, or another chicken coop can be built. Elastic plastic net or bamboo woven net is installed in the small chicken house, the mesh diameter is 1 cm, and the net is about 100 cm away from the ground. If the old house transformation, should open the daylighting window and the ground window before and after. Daylighting windows are 150 cm from the ground and ground windows are 20 cm from the ground. The window size is determined by the light in the room, generally to the chicken during the day can find food and water position. The windows were sealed with barbed wire to keep out intruders. If newly-built chicken coop, usable bamboo weaves a net around, spring, winter season adds 2 white farming film, leave good transom and ground window. Material trough and drinking water can be replaced by bamboo tube, evenly placed in the house. Small logs are horizontally installed in the middle chicken and large chicken coop as perch racks. Small logs about 8 cm in diameter. The first row is 35 cm away from the ground, and the second row is 40 cm away from the ground. It is installed according to the ladder shape, and the row spacing is about 30 cm. Installation should be firm, so that chickens fly on the perch frame does not shake, do not collapse. Other structures are the same as small chicken houses.

2. Do a good job of preparation before entering the chicken house, the four walls and the top of the old house should be painted with concentrated lime water for 1-2 times, whether it is reconstructed or newly built chicken house, strict disinfection, good hygiene, verification of temperature control and ventilation facilities in the house.

3. Chick source for reducing foreign chickens bring germs and do pure varieties, it is best to keep breeders, self-breeding chicks.① Breeders choose pure native chickens with bright coat color, strong and fast growth speed. The hen weighs about 1.6 kg, the rooster weighs 1.6-2.25 kg, the ratio of male to female is 1:10, and the breeding male and female are not suitable for brother and sister chickens.② When the farmer adopts the hen hatching method, in order to unify the age of the chicks, in addition to uniform feeding and timely shelf life, the hens hatched first are carried out empty incubation (no eggs are placed in the nest), but the empty incubation time should not exceed 7 days. Incubator should be adopted to hatch chicks in large-scale breeding.

4. Scientific feeding ① After hatching, chicks are fed brown sugar water first to increase appetite and promote meconium excretion. After drinking water, chicks are fed less and more meals. The chickens are fed 5-6 meals a day and the chickens are fed 3-4 meals a day. (2) Scientific ingredients: chicken meat and chicken complete feed; chicken self-ingredients: grain germination feed 40%, rice bran 25%, corn flour 15%, all kinds of green vegetables leaves (clinker can be root leaves) 15%, blood powder 5%; chicken self-ingredients: grain germination feed 70%, all kinds of green vegetables leaves 25%, blood powder 5%. Self-ingredients for winter clinker.

5. Scientific management ① Chickens enter the brood room, 50 per square meter in the first week, and separated into a group, fresh and clean dry straw is spread on the elastic plastic net or bamboo woven net, and the thickness of the grass is suitable for chick feces to fall to the ground from its gap. 40 chickens per square meter in the second week, removing the grass, so that chicken manure directly falls to the ground in the mesh, 30 chickens per square meter in the third week, and then 10 chickens. (2) Chickens were raised in groups according to age, strength, size, male and female. (3) The temperature of chicken house was 32℃ in the first week, and then decreased by 2.5℃ every week until the natural temperature was 21℃. 4. 1 hour of light and 3 hours of darkness are adopted as 1 cycle interval light, so that the activity and rest of chickens are appropriate, the growth of native chickens is promoted, the feed utilization rate is improved, and the electricity cost is saved at the same time. Light intensity refers to the light intensity of daylight windows. Chicks can graze at 25 days old, which is one of the important factors to ensure high survival rate. 6. The training of chickens on the perch rack should be carried out at the end of the evening. First, a small number of chickens should be caught on the perch rack. When catching chickens, do not turn on the lights. Shine the chickens that have been caught on the perch rack with a flashlight and arrange them side by side. Some chickens are not used to it for the first time, or jump down, or squeeze other chickens from the perch, and need to catch them repeatedly for 2-3 times. After all of them are caught, they close the light. After 1-3 nights, they begin to get used to it. Then this small number of chickens lead the rest of the chickens to fly to the perch. 7. Regular ventilation, keep the air fresh in the house, ventilation in spring and winter should pay attention to heat preservation, and strictly prevent ventilation.

6. Prevention measures are mainly based on prevention, so that chickens eat and drink water every day. Medium chickens and large chickens spend the night on the perch rack, in pairs and in their respective positions, which is conducive to frequent inspection of chicken manure and finding out the corresponding sick chickens. In addition, sick chickens do not fly up the perch when they enter the house. When the chickens go out, sick chickens will not fly off the perch, and seriously ill chickens will fall down from the perch, so as to find sick chickens. Discovered sick chickens immediately isolated, clean feces once a week, rainy and snowy weather is strictly prohibited grazing, so as not to wet chicken feathers, so that chickens catch cold. Grazing sites should be checked in advance and dead animals should be discarded immediately to prevent chicken poisoning.
