Local chickens have a low incidence due to their strong adaptability. They use less drugs in their lives than breeders and are safe to eat. Furthermore, because of its high protein content in chickens, it is delicate and succulent, mellow and mellow, and it is increasingly favored by urban and rural residents. The price of local chickens is also known every day, which is usually 2 to 3 times that of ordinary hybrid chickens. In the east of Yudong, the use of orchards, fields, and groves for open or semi-open broiler chickens has become a new bright spot for farmers to increase income. In view of the situation and problems of feeding chickens in this zone, the author believes that the following points should be noted in order to raise good chickens:
1 Select the site of the site to be selected far away from residential areas, railways, highways and other main farms, no industrial waste and pesticide pollution sources nearby, more live insects, lush grass, easy access to water, geographically open, easy to manage The place.
2 Doing a good job of raising chicks to raise chicks (usually 0 to 35 days old) Due to incomplete development of the digestive system and immune system, poor plumage, poor foraging ability and body temperature regulation, and high requirements for the growth environment, it is not appropriate to stocking. It should be cultivated indoors. The temperature of the brooding room should be kept between 30°C and 33°C for 1 to 3 days, then 2°C every week. If the coal stove is used for heating, pay attention to ventilation to avoid high carbon monoxide causing chicken gas poisoning. The feed should be selected from the fine materials that are easily digested and absorbed, such as millet and broilers, and gradually adapt to herding life after the body is strong.
3 Set up a temporary shelter in the rearing area and choose a lee, sunny, open, high-lying, well-drained vacant land and build a temporary shelter. The brackets can be used for trunk steel pipe, bamboo poles, etc., fixed with iron wire and covered with blue canvas or plastic film. The winter sheds are covered with straws made of plant stalks to facilitate the insulation of the sheds. Sheds can be made "shelf" type or "person" type, and the size of the shedding house depends on the number of breeding. The door of the shed was opened on the sunny side. After it was set up, it was hauled around with a wire to prevent it from being blown down by the wind.
4 The rational feeding of native chickens is based on open-breeding, which is usually based on the collection of insects, grass leaves, and grasses. The required nutrient preparation is not as strict as the requirement for cage chickens, but if it is supplemented only with coarse grains such as corn and wheat bran, Causing anal fistula, hair removal, malnutrition, especially in the pre-growth period, in the grazing gap, pay attention to protein, minerals, vitamin supplements. In the late growth period, for the taste and food safety of chicken, supplements should be based on coarse grains such as corn, soybean cake, and bran, and the drugs and various additives should be fed as little as possible. Ten days before the chicken was marketed, drugs, fish meal, and choline chloride were stopped feeding.
5 The timely cutting of small roosters in the cockerel after cutting, the reduction in the number of androgen secretion, body weight gain, feed conversion rate, good meat quality. Local chickens are generally cut at 40 to 70 days of age. In order to make the operation go smoothly, generally fasting for 15 hours before castration, in order to reduce the wound infection, the surgery is generally performed on a sunny morning, after the castration, the chickens should be given anti-inflammatory drugs (oxytetracycline, penicillin, SMZ, etc.) and fed according to instructions. 5 days.
6 Do a good job of prevention and control of the epidemic disease "will not keep busy, do not understand prevention of disease and take the money." In recent years, due to the high incidence of chickens, epidemic control work has become the key to the success or failure of chicken farming. In order to do a good job in this work, the breeder should always observe the chicken's feeding, excrement, spirit, and activities, find problems, and take early measures so that no disease can be prevented and the disease can be treated early. The following procedures can be used for the prevention of chicken disease:
6.1 Chicken chicks were injected with 0.2 ml of live turkey virus herpes virus within 24 hours after hatching to prevent Malik.
6.2 Chicks are 3 days old and drink water with 0.01% potassium permanganate solution to prevent digestive diseases.
6.3 The chicks were 10 days old and were spotted or nasally vaccinated with Newcastle disease virus IV attenuated seedlings.
6.4 The chicks are 20 days old and the venom of the bursae of the bursae is venomous or watery.
6.5 The chicks were 30 days old and used eye drops or drinking water.
6.6 The chicks were 45 days old and were injected with Newcastle disease I strains.
7 Strengthening daily management Even though chickens are kept more extensively than breeders, it is still necessary to formulate strict measures and strengthen management. Such as keeping the animals as little as possible to the outside world, entering and leaving the site to be disinfected; outsiders are prohibited from entering to prevent cross-infection of the disease; sheds should be cleaned regularly, excrements should be cleared in time, and bedding, huts and utensils should be changed regularly, and the chickens should be regularly sterilized. Carry out innocent treatment such as deep-buried or incineration; put protective nets around the chickens in stocking areas to prevent birds from getting lost, prevent pigs and dogs from entering, and harm chickens; pay attention to weather changes in high winds and stormy days Stop grazing; in the hot season, to prevent heat stroke, shading less to build awnings, enough to drink water; appropriate increase in the proportion of energy feed in the winter, while paying attention to the insulation of the shed, pay attention to ventilation to prevent ammonia, carbon monoxide poisoning All-in and all-out systems are implemented. Before the birds enter, the huts and utensils must be completely disinfected.
