Native chicken breeding technology and chicken farm construction scheme

Choose the site: choose the area far away from the village, convenient transportation, north to south, shelter from the wind and the sun. Construction of greenhouse chicken house: building materials are bamboo, wood strips (scraps of saw board), plastic film, shading net, reflective paper and so on. Chick requirements: select healthy chicks with flexible action, loud calls, no navel nails and no pile. Late management: can feed bran wheat, corn, bean cake, bean curd dregs, bean powder and other coarse feed. Prevention and treatment of diseases: vaccination according to different growth stages.

First, choose the site

The chicken farm is suitable to choose the hillside far away from the village, convenient transportation, north to south, shelter from the wind to the sun, abundant water resources, easy to manage, in the shape of a kettlemouth (a small mountain pass and a large hinterland), and a slope of less than 25 °, which is convenient for the transportation of materials and products during this period. it can also enable chickens to have a sufficient range of activities and feeding sources, which is conducive to the healthy growth of chickens.

Second, the construction of greenhouse chicken house

1. The construction of chicken house in greenhouse is generally based on the principle of economy, convenience and flexibility, and local materials are used. The main building materials include bamboo, wood strips (scraps of saw board), plastic film, shading net, reflective paper and so on.

2. Farmers raising native chickens in mountainous areas generally build a double-layer chicken house covering an area of 132 square meters, with a length of 22 meters, a width of 6 meters and a height of 2.3-2.5 meters.

3. The interior is made of bamboo as a support frame, and the wood strips from the bottom of the saw board are used as planks, which are constructed into a middle layer 0.6 meters high above the ground and an upper layer 0.6 meters above the middle level. such a multi-shelf and dry and clean native chicken habitat, a two-layer chicken shed with an area of 260 square meters (middle and upper layers) can raise a batch of native chickens.

III. Requirements of chicks

1. Chicks need to be purchased from a regular production incubator with a production license. During this period, healthy chicks with flexible action, loud calls, shiny feathers, no navel nails and no stacking are selected. After coming out of their shells, they need to be vaccinated against Marek's disease and transported to the henhouse within 24 hours.

2. The chicks need to keep warm after entering the rearing room, raising 40-50 chicks per square meter, and then gradually reduce the breeding density in the later stage, keep the room temperature at about 30-32 ℃, then decrease by 2 ℃ per week, take off the temperature after 25-30 days, raise them in the mountains during the day, and raise them in the greenhouse at night.

3. The chicks drink water before feeding, and antibiotics and vitamins can be added to the drinking water for about 3 days, which can enhance the physique of native chickens and improve their anti-morbidity. Chicks need to be fed with full-price pellet feed.

IV. Post-management

The main results are as follows: 1. The free-range native chickens of 30-50 days old should be raised and managed according to the growth stage. During this period, according to the characteristics of extensive feeding, tolerance to rough feeding and fast growth, they can be fed more agricultural and sideline products.

2, such as bran wheat, rice, corn, bean cake, rapeseed cake, bean curd dregs, bean powder and other coarse feed, properly increase the feed of trace elements. The feed ratio is 55% Mel 65% for cereals, 5% MUE 10% for bran, 15% MUE 25% for plant legumes, plus other fodder, it is not suitable to feed animal feed.

V. Prevention and treatment of diseases

1. Although native chickens are raised in mountain greenhouses, although there are few diseases, they also need to implement the principle of comprehensive prevention and control. According to the immunization procedures of native chickens, chicks need subcutaneous injection of Marek's disease vaccine within 24 hours; 7-day-old chicken TV vaccine and Chuan Zhi H120 vaccine are given nasal drip or drinking water; 14-day-old avian influenza vaccine is subcutaneously injected. At the age of 21 days, the attenuated vaccine against infectious bursal disease (IBD) and the TV vaccine of Newcastle disease were given water.

2, 30-day-old intrawinged fowlpox vaccine; 35-day-old infectious bronchitis H52 vaccine drinking water; 45-day-old subcutaneous injection of avian influenza vaccine; 60-day-old intramuscular injection of Newcastle disease Ⅰ vaccine or inactivated vaccine; local laying hens were subcutaneously injected with avian influenza vaccine 14 days before laying, and combined vaccines such as egg reduction syndrome, Newcastle disease and infectious bronchitis.

3. At the same time, it is necessary to use anti-coccidiosis drugs or traditional Chinese medicine alternately at the age of 15-60 days according to the situation of native chickens in mountainous areas, and to take deworming drugs before and after 15-20 days and every other month to control the occurrence of native chicken nematode disease.
