Heifeng Wuji, also known as Black Feather Chicken, is known as "China Black Po". Grassland grass slopes, fruit and vegetable lands, and reservoirs can be used to create good aquaculture benefits. The breeding techniques are now described as follows: 1 The chicken house construction area is 30-40 square meters, and it can be built into a single-shelf corridor shed north to south. There are 1 large and small window on both sides of the north and south sides, and the south wall has free entrances and exits and a playground outside. Feeding troughs and drinking fountains are evenly distributed in houses and on sports grounds. Egg laying boxes are placed on the inside of the house and the other side is provided with perch. A corner of the stadium is provided with sand. There should be a wood or orchard next to the chicken house so that the birds can cool off in the shade when the sun shines violently. There must also be a relatively flat open area, preferably with abundant grass and sand blocks, allowing chickens to freely inhabit and feed. 2 Feeding Management 2.1 Chickens from hatching to 30-day-old chickens are called chicks. Breeding black brooded broilers is the key to brooding. 1 eat. Chicks can be eaten on the second day after hatching. In the first 3 days, the broken rice soaked in boiling water was fed, and the appropriate amount of sesame and cooked yolk was added (every 100 chicks were fed 3-5 yolks). Spread the feed on a plastic sheet to induce chickens to feed. From the fourth day, the compound feed was fed in a small feeding trough (the height of the trough was the same height as the back of the chicken). From the 7th day onwards, green feed that accounts for 10%-20% of the total amount of feed can be fed. After 7 days of age, chicks can be added with 2% to 3% of the fine sand for their free intake to enhance their digestive function. The chicks were fed 6-8 times a day within 21 days of age and fed 30 minutes each time; after 21 days of age, they were fed 4-5 times a day. 2 drinking water. Chicks can drink water 20-30 hours after hatching. They should be fed with 0.2% potassium permanganate solution. Drinking water is generally 1.6 times the feed intake. Chicks can not regulate their body temperature before 21 days of age, and can adopt “high-temperature brooding method†(such as furnace fire heating, electric umbrella, infrared heating) brooding. The temperature requirement is: 0-7 days old 25-27°C; after 21 days old, the temperature is controlled around 23°C. The relative humidity in the brooding period is generally 55%-65%. The chicks were exposed to light for 20-22 hours per day within 7 days of age. After 7 months of age, the chicks gradually reduced light exposure to 13 hours, and gradually transitioned to natural lighting. In general, the light bulb is 2m away from the ground, and the light intensity is 15-20W per 10m2. From the 21st day of age, chicks are allowed to basking in the grazing land and eating grass in sunny weather at temperatures around 20°C. Open the window when the temperature is high at noon, so that fresh air enters the house. Appropriate density for stocking per square meter is: 40-50 on 10 days, 40 on 20 days, and 30 on 30 days. 2.2 Chickens Chickens that have been defrosted to 165 days of age are called medium-sized chickens. According to their uses, they can be divided into two types, namely, dietary chickens and reserved breeder chickens. Their feeding and management methods are different. Breeding methods of breeders are divided into three types: ground level raising, online raising and cage raising. 1 feeding and management of broiler chickens. The conditional feed is best fed with full-priced nutritional commercial broiler feed to facilitate weight gain. It can also feed self-mixed feed, combined with grazing. During the period of grazing, feed supplements should be added sooner or later, free-range food intake should be provided, and drinking water should be sufficient. If there are no conditions for stocking, the proportion of green feed and ingredients in the chicken diet should be 1:1. Maintain proper temperature, humidity and light throughout the breeding process. The density of chicken houses is 12-15 for 31-60 days and 10-12 for 61-90 days. 2 rearing breeder breeding management. The first is to adopt a restricted feeding method, that is, to limit the quantity and quality of the chicken's diet, but to ensure that the drinking water is sufficient and clean; the second is a reasonable group, each group is suitable for 150-200; Third, the proper breeding Density, feeding 6-8 eggs per square meter; Fourth, ensuring light, using 8 hours of light per day; Fifth, strengthening the movement of reserved chickens; 6: Deworming at a proper time, driving locusts once every 70 days, and driving the production Aphids, aphids, and blood-sucking insects are each used once. The medicines have insect repellent nets, extermination spirits, etc., and they are used as described.
