Grass chicken breeding technology, grass chicken scientific free-range breeding technology

Grass pheasant is a local chicken breed that has to be kept by the farmers themselves and has been raised for a relatively long time.

At present, some of the grass chickens sold in farmers' markets are indeed local chicken breeds, but they are raised in captivity or greatly shorten the breeding period with synthetic feed; some are broiler chickens, but they are kept separately by farmers themselves, and the breeding period is relatively long. Grow up by eating grains, vegetable leaves and bugs. The above two kinds are not real grass chicken.

According to farmers who have experience in raising grass pheasants, genuine grass chickens can be identified from their appearance, that is, by looking at chicken heads and feet. Usually the grass chicken head has a small mouth, the chicken legs are relatively thin, the claws are small, pointed, rough and powerful, and the chicken skin is thin, smooth and tight. On the other hand, captive chickens have short feet, round claws and thick meat.

The following is a summary of the scientific breeding technology of grass pheasant, just for your reference!

I. Variety selection

Suzhou local breed Qiongdongshan Chicken can be selected, which is mainly characterized by yellow feathers, thin feet, strong disease resistance, fat body and strong body, and the single chicken is generally heavy 2.0~2.5kg.

II. Site selection

Choose dry land, sloping land or wasteland facing north and south, next to a large area of orchards, grasslands or mountains as stocking grounds. Plastic sheds can be built or old buildings can be transformed into chicken sheds. The middle of the shed is high, low on both sides, 4 meters wide, and 2. 5-3 meters high in the middle. 5-3 meters, dripping eaves on both sides are 1. 2-1. 5 meters, covered with hairy grass, dig drainage ditches around. The floor area of the chicken house is calculated according to 8-10 pieces / m2. According to the density of chickens, put a simple fence around the site, cover with rain-proof awning, set up a feed level for every 30-50 chickens on the site, and 80 chickens use a water fountain.

3. Brooding

Before entering the chicken, the henhouse and the environment should be thoroughly washed and strictly disinfected. The temperature of chicks should be 33-35 ℃ when they enter the house, and then decrease by 2-3 ℃ per week until the temperature is de-heated. After entering the house, young chickens should be provided with clean warm water to adapt to the new environment as soon as possible, reduce stress and prevent dehydration and yolk absorption. Add 3%-5% glucose before 3 days old. After drinking enough water (3-5 hours after entering the house), the chicken begins to eat with broken particles, allowing it to eat freely, and pay attention to "adding frequently and feeding less".

While keeping warm in the chicken house, we should pay attention to ventilation. 1Mel 30 days old was exposed to light for 24 hours. After 30 days of age, the light was reduced by 1 hour a day until the transition to natural light. The light intensity was 4 watts / m ~ 2 at the age of 1-30 days, and then gradually decreased, so that the chicks could see eating and drinking water.

At the age of 0-2 weeks, 80 animals per square meter, 40 birds per square meter at the age of 5 weeks, 18 animals per square meter at the age of 10 weeks, and 12-15 animals per square meter after 11 weeks of age, which can be flexibly controlled according to the season and climate. The beak was cut off at the age of 7-8 days, and the beak was repaired at the age of 30 days if necessary.

IV. Grass chicken grazing

Grazing is generally chosen from the beginning of April to the end of October, where vegetation is luxuriant, insects, ants and other insects thrive, and chickens can get sufficient ecological feed. In other months, captive breeding is mainly used, supplemented by grazing. The warm-free chicken seedlings can choose appropriate grazing in a small area when the outdoor wind is small and the temperature is high in sunny days, the first time is about 1 hour, and then gradually extend the grazing time until all-weather grazing. When grazing around the clock, there should be forage grass that can be fed, such as white clover, purple flower head, Rumex, Juba and even Chinese cabbage, sweet potato leaves and so on. Grazing grounds should be able to provide emergency shelter from rain and sun. At the beginning of grazing, the chicken seedlings are too small to be placed in the grass above the back of the chicken. The breeding chickens that return to the shed in the evening should be fed properly, mainly corn, wheat, soybean meal and other grains, with a feed quantity of 20-30 grams per chicken. Appropriate amount of trace elements and multivitamin should be added during feeding to increase the immunity of the body.

V. Disease prevention and treatment

Must be in accordance with immunization procedures and preventive administration to prevent, mainly to prevent and cure parasites, large% bacilli, staphylococci and other infections and poisoning. Grazing chickens are prone to parasites, mainly coccidia, trichomonas, white cell worms and so on. For newly grazed chicken seedlings, the decoction of Bupleurum and Changshan was used for drinking water, for preventive deworming, and 0. 5% for grazing grounds. 0.2% caustic soda solution was disinfected.
