The technology of raising native chicken

Native chicken, a kind of poultry. Different from caged broilers. Among them, "hillside scattered raising native chicken" is the best. Let's take a look at the techniques of raising native chickens.

1. Choose a suitable venue:

Native chicken breeding should choose places with leeward to the sun, flat terrain, high dryness, convenient access to water, far from the village, convenient transportation, small canopy and sparse fruit trees. Do not densely spread chicken farms along the river, the distance between the farm and the farm is not less than 200 meters. Make use of the advantage of the natural barrier in the mountain area, advocate one mountain package and one field.

2. Site disinfection:

In the new site, the nursery was sprayed with 5-10% lime water or 1: 600 100 disinfectant, 1purl 1200 disinfectant, 2% caustic soda, etc. The old site, ground cleaning and washing, on the basis of the above methods, more wonderful content, please pay attention to Fumu net, fumigation with potassium permanganate 14g / m2 plus formaldehyde 28ml / m2 for 1-2 days (put drinking fountains, buckets and other utensils together into disinfection), open ventilation for 1-2 days.

Third, temperature requirements:

Temperature is the key to the success of brooding. The temperature should be adjusted half a day before entering the chick. Generally, the temperature in the nursery should be controlled at 32-33 ℃ at the age of 0-1 week, and then decreased by 1-2 ℃ per week until 4 weeks old. There are two ways to observe whether the temperature is appropriate: one is to look at the thermometer, and the other is to look at the condition of the flock. When the chickens gather together, close to the heat source, constantly chirping, indicating that the temperature is on the low side; when the chickens are far away from the heat source, distributing around, constantly opening their mouths to breathe, it shows that the temperature is on the high side; when the chickens are evenly distributed, move freely and relatively quiet, it shows that the temperature is more suitable.

Fourth, choose high-quality chicken seedlings:

The quality of chicken seedlings plays a decisive role in the success of raising chickens. At present, Jiangcun Yellow, Sanhuang Chicken, Guangxi Ma Chicken, Zhejiang Dahuang Chicken, Gushi Chicken, Xianju Chicken, Fujian Blue Chicken and other small and medium-sized late-speed chickens have the characteristics of low environmental requirements, wide adaptability, strong disease resistance, large activity, high meat quality and so on. It is more suitable for wild breeding in our city. Chicken seedlings with purer breeds and strong physique should be selected. In general, the chickens with lively flocks, powerful calls, big heads, protruding eyes, powerful struggle, clean body, uniform individual and consistent coat color are high-quality Miao chickens.

5. Boil water as soon as possible:

Chicks drink boiled water for the first time. When the chick arrives, send it to the nursery as soon as possible (especially necessary in winter) so that it can drink freely. For chicks after long-distance transportation or hot weather, 0.9% glucose saline and quick supplement are added to drinking water, and 0.01-0.02% potassium permanganate is added to close drinking water. Boiled water should be early, so that more than 80% of the chicks drink the first sip of water at the same time; those who are slow to respond and squat motionless should be trained manually, or clapped hands to stimulate drinking water. Water should be supplied round the clock.

6. Timely opening of materials:

Feed the chicks for the first time. The opening time should be postponed appropriately, and the most suitable time should be 24-36 hours after the chicken came out of the shell. It can also be determined according to the health status of chicks and external air temperature. Generally, 85% of chicks have an appetite. If the feed is opened too early, it is easy to cause the chicken yolk to be stiff due to malabsorption of yolk, which leads to the decrease of brooding rate and poor evenness. When opening the material, it is best to choose the formula feed with small particle size and easy digestion. Feed should be sprinkled on nylon cloth or dustpan to make chicks easy to eat, and should be added as little as possible to stimulate chicks' appetite and reduce feed waste.

7. Appropriate feeding density:

The feeding density of native chicken can be slightly larger than that of fast chicken, which is generally controlled at 35 per square meter in one week, and then decreased by about 5 per week until the four-week-old is out of temperature.

8. Do a good job in immunization:

Native chicken has a long feeding period, and its immunity should be different from that of fast chickens raised indoors.

1. Choose high quality vaccine. As the native chicken has a long breeding period and a great threat to the epidemic disease, when choosing and purchasing the vaccine, it is necessary to check the validity period, batch, manufacturer and production date of the vaccine, and put an end to the use of the vaccine if it is found to be broken, lytic, invalid or with impurities. You should buy it from a store designated by the agricultural department.

2. The vaccine should be used in sufficient quantity. Other aspects of native chicken farming can be saved, but the vaccine cannot be deducted and should be used in sufficient quantities. The method is as follows: in the early stage, if the amount of drinking water immunity should be doubled (that is, 1000 chickens, use 2000 feather vaccine), the dose of intravenous immunization should be 1-1.5 times, and it should be 1.5-2 times in the later stage.

3. Reasonable immunization procedure. 4-5-day-old H120 vaccine, 8-10-day-old Ⅱ or L vaccine, 13-15-day-old bursa vaccine and avian influenza vaccine, 25-26-day-old bursa vaccine, 28-30-day-old series I vaccine and avian influenza vaccine, 32-34 days old H52 vaccine. If the feeding period is more than 100 days, it is recommended to inject Series I vaccine at the age of 60-65 days.

4. Adopt the correct immune method. In the early stage, because the chicken is small, the activity is small, and it is easy to be caught, it should be advocated to be immunized one by one by nose, eye or mouth, and the injection method should be adopted in the later stage, which can ensure that the immunity of the chicks is in place, the immune effect is true, and prevent drinking water immunity from bringing about more and less drinking. even the malpractice that can't drink, cause immune dead corner.

IX. Prevention and treatment of major diseases in the brooding stage

1. White dysentery. The disease mainly occurs within 7 days of age and is characterized by white feces adhered to the anus of chicks, which is prevented and treated with enrofloxacin, norfloxacin, diclofenac, oxytetracycline and other drugs.

2. Mycosis. It usually occurs within half a month of age, characterized by dyspnea, body dehydration, weight loss, and the presence of fungal nodules in the pulmonary balloon. Prevention and treatment should put an end to mildew feed, reduce the humidity in the house, often change the cushion, can be treated with nystatin.

3. Coccidiosis. It is characterized by loss of appetite, increased drinking water, bloody stool on the site, and bloody stool around the anus of a few chickens. The cecum and small intestine were thickened with blood thinner and bleeding spots could be seen in the intestinal mucosa. The treatment with penicillin, sulfonamides and coccidiosis, combined with reducing humidity and feeding density in the house, achieved good results.

10. Key points of feeding and management in the later stage

In the later stage, the feed can be gradually transferred from formula to single corn (2318,-5.00,0.22%) and rice. Generally, the material is fed after 10:00 in the morning, once after 3pm, and added again before falling asleep. The water will not stop throughout the breeding period. Regular observation, found that mental, appetite, fecal abnormalities, should take measures as soon as possible. It is necessary to get rid of sick and dead chickens in time to prevent animals such as rats, eagles, snakes and weasels.
