Large-scale chicken farming technology

As people's living standards improve, the demand for chicken has increased due to its firm texture, delicious taste and high protein content, and there are chicken farms in many areas. Here is an introduction to large-scale chicken farming technology .

1. Site requirements

The site selection for the breeding farm requires a quiet environment, high and dry terrain, sheltered from the wind and facing the sun, sufficient lighting, adequate water sources, good water quality, and unobstructed drainage. There must be no pollution sources that pose a threat to the site environment within a radius of 500 meters or upstream of the water source, and the farm must have good isolation conditions and an area with good natural green vegetation.

2. Construction of enclosures

The enclosure runs east-west and faces north and south. Cement floor, smooth surface. The walls are made of brick-concrete structure, the closed chicken coop has solid walls with large windows, and the semi-open chicken coop has walls that are 1.5 meters high. The support is made of steel and brick structure, and the roof is made of heat-insulating color-coated steel shed. The chicken coop is of double slope type, with a roof height of 3.8 to 4.5 meters and an eaves height of 3.0 to 3.5 meters. The span of the chicken house is more than 6 to 8 meters, the spacing between the side wall columns is 5 meters, and the total length is determined by the number of chickens to be raised. The span and length are adjusted according to the actual terrain. The stocking density should be 10 chickens per square meter.

3. Construction of Habitat Sheds

2 to 3 straw huts are built in the grazing area as shelters for rain shelter, sun protection and grazing. The shed should be located in a place that is sheltered from the wind and facing the sun, with relatively flat terrain and no water accumulation, and surrounded by woods or orchards so that the chickens can have shade, shelter from rain and roost at night. The shed is single-slope or double-slope, 4 to 5 meters wide and the length depends on the number of animals raised. The roof is 2.5 meters high and the eaves are 2 meters high. The distance between the two pillars is 5 meters. The span and length can be adjusted according to the actual terrain. A perch is built in the shed. The surroundings can be closed with corn stalks or plastic nets in winter to keep out the cold, and it can be completely open in summer to provide shade and shelter from rain, and keep warm in winter and cool in summer.

4. Temperature control

Temperature is a key condition for the success of chicken farming, especially during the brooding period, providing a suitable temperature is the key to improving the survival rate. The entering house temperature is controlled at 34.5℃-35℃ (adjusted according to the strength and distribution of the flock). It is lowered by 0.4/0.5℃ every day in the first 7 days before brooding. It is lowered by 0.3℃ every day after immunization at 7 days of age and continues until 26 days of age. After 26 days of age (when the molting is finished), it is lowered by 0.4 or 0.5 every day and reaches 23℃ on 35 days. The specific temperature depends on the performance of the flock and the weather conditions of the day.

5. Humidity control

Relative humidity during the brooding period is another environmental indicator that is crucial to broiler growth, but it is also an issue that is easily overlooked. Appropriate humidity will make the chicks feel comfortable, have a good appetite and develop normally. Reasonable humidity in the early stage (60%-70%) can effectively reduce the occurrence of respiratory diseases. The humidity during the brooding period is generally required to be controlled at 65%-75%, and the humidity requirements in the middle and late stages are relatively low.

6. Feeding management

The feed is mainly concentrated feed such as raw grains such as corn, grains, wheat, sorghum, beans or their processed by-products, supplemented by green plants (grass) or green feed such as pollution-free vegetable stems and leaves and sweet potatoes. Take safety precautions to prevent harm from natural enemies such as weasels and wild cats. The local chickens are marketed when they are over 150 days old to ensure their quality.

7. Disease prevention and control

Clean the waterers and feeding troughs every day to keep the chicken house clean and dry. Chicken farms are not allowed to raise other poultry at the same time. Adhere to the disinfection system, set up disinfection pools at the gate of the chicken farm and the entrances and exits of the grazing area, strictly implement the disinfection system, and insist on regular spray disinfection of chicken houses and grazing areas. It is strictly forbidden to use banned drugs, and the medication and withdrawal periods must be standardized. Antibiotics shall not be used after 100 days of age. Deworming should be done once a month during the stocking period, and feces should be removed promptly 1 to 2 days after each deworming. Anticoccidial drugs should be added and used according to the instructions.
