Chicken breeding techniques

Local chickens are also known as grass chickens and stupid chickens. They refer to broiler chickens that are stocked in mountain forests and orchards. In the past few years, due to the disadvantages of slow growth, small individuals, and low egg production, local chickens have gradually been replaced by foreign fine varieties, and the number of cultured chickens has been greatly reduced. However, as consumers' requirements for food taste and quality have gradually increased, “chicken chicken” breeding has become a new hot spot in the breeding industry.

I think there are several reasons why local chickens are popular among farmers. (1) Non-pollution, delicate meat, good taste, rich nutrition, welcomed by people; low cost of farming, not only less investment in chickens and epidemic prevention, but also less consumable consumption, a local chicken only needs about 4 yuan a year the cost of. (2) Flexible feeding and easy management. The use of free-range methods requires the breeder to master general techniques. (3) The income is considerable and the profits are large. The price of local chickens and local eggs in the market is generally higher than that of meat chickens and eggs. Based on the local chicken's lower price of 12 yuan per kilogram, a local chicken weighing 1.5 kilograms can earn 14 yuan. If a farmer raises 200 local chickens for 1 year, it will have a net income of 3,000 yuan.

Native chicken breeding techniques should focus on the following aspects:

The choice of breeding site

The places for stocking must be far away from residential areas, industrial and mining areas, and arterial roads, and require quiet and peaceful environment, clean air, and nearby clean water sources such as clean streams and ponds. Looking for a leeward flatland in the stocking area, take a simple south-facing hen house, and you can build a plastic greenhouse to provide lunch breaks and suffocation places for chickens. The structure of the chicken house can be transformed into an old house, or a chicken house can be built. The chicken house is equipped with an elastic plastic net or bamboo net with a mesh diameter of 1 cm and a net of about 100 cm from the ground. If the old house is renovated, light windows and floor windows should be mined before and after. The lighting window is 150 centimeters from the ground and the window is 20 centimeters from the ground.

Management of young chickens

1 Preparation of the house

Do a good job of preparation before entering the chicks. The chicken house reformed in the old house shall be painted 1 to 2 times with thick lime water in the walls and on the top. Whether it is reconstructed or a new chicken house, it must be strictly disinfected and sanitized. Interior conditioning and ventilation facilities.

2 The source of the chick

In order to reduce the number of foreign chickens and make them pure, it is best to keep the chickens and rearrange the chicks.

2.1 Breeders choose pure, light, strong, fast-growing pure chicken. The weight of the hen is about 1.6 kg, the weight of the rooster is 1.6-2.25 kg, and the male-male ratio is 1:10. The breeding male and female chickens should not use brothers and sister chickens.

2.2 When the farmer adopts the hen hatching hatching method, in order to unify the chicks' age, the hatched hens shall be hatched (without eggs in the coops) except that the feeding is performed evenly and the quality is ensured on time. The time should not exceed 7 days. It is advisable to use an incubator for hatching during mid-scale feeding.

3 Scientific Management

3.1 Chickens enter the brooding room, 50 eggs per square meter in the first week, and are divided into a group of fresh and dry straws on a flexible plastic net or bamboo-woven net. The thickness of the broilers can be dropped from the gaps of the chickens to the ground. . In the second week, there were 40 animals per square metre, and the grass was removed and the chicken manure was dropped directly onto the ground through the mesh. In the third week, there were 30 animals per square metre, followed by 10 animals.

3.2 Rearing chicks according to their age, strength, size, and male-female separation.

3.3 The temperature in the first week of the house is 32°C, after which it is lowered by 2.5°C every week, and it is deheated to a natural temperature of 21°C.

3.4 Use 1 hour of light, 3 hours of dark 4 hours for 1 cycle of light, so that chicken activities and rest amount, promote the growth of the chicken and improve feed utilization, while saving electricity. The light intensity refers to the light intensity of the daylight window.

3.5 Chicks can be grazing at 25 days old, which is one of the important factors to ensure a high survival rate.

Stocking

1 Restocking scale: It is advisable to stock 2,000 in one piece of forest land. Large-scale inconvenience management will result in low scale and low benefit. Late spring to mid-autumn can be stocked, winter temperatures are low, Cordyceps is reduced, and stocking should be stopped.

2 Restocking methods: The chickens should be selected from strong breeder chickens that are resistant to disease. Like the ordinary brooders before 3 to 4 weeks of age, the rooms with good insulation properties are selected for artificial brooding, and then transferred to the mountains for stocking after de-warm. When the chickens began to be stocked, they did not have the habit of going to the mountains and they had to train artificially. It usually takes 2 people to cooperate. One person whistles in front of him and throws the pellets to feed. The chicken then snatches the food. The other uses the branches to drive away until the chicken is all up. At noon every day, it is also necessary to fill the mountain with a whistle to supplement the food once. Intensive training is conducted. In the evening, the same method is used to teach chickens to go home. After training for about 10 days, the chickens have established conditioned reflexes.

3 Precautions: A few days from the start of stocking are stress-resistance. A certain amount of vitamin C or multivitamins can be added to the feed or drinking water; no antibiotics and anthelmintic drugs are required for the first 3 months after the cage is released.

prevent disease

Disease prevention measures are mainly prevention, and it is necessary to observe the feeding and drinking conditions of chickens every day. It was found that the diseased chickens were immediately isolated and the excrement work was performed once a week. In rain and snow, grazing was strictly prohibited so as to avoid wet feathers and make chickens catch cold.

The most harmful to chickens, but also the most popular is chicken gizzards. Chicken gizzards are a highly contagious and devastating disease caused by the Newcastle disease virus in chickens. The mortality rate is almost 100%. The disease can occur throughout the year and is more prevalent in hot summer days. Farmed chickens pay attention to nature and ecology, avoiding the use of chemicals
