Chai chicken breeding technology

Chaiji, also known as stupid chicken, is characterized by resistance to roughage, adaptability, foraging, stable genetic properties, strong nesting, and strong disease resistance. The average weight of a 6-month-old cock is 2 kg, and that of a hen is 1.5 kg; Sexual maturity is 6.5 months, and production is 8 months old; 600-day egg production is 180--210 eggs (7--9 kg), average egg Weight 40--42 grams, eggshell color is mostly white, light brown; its large proportion of egg yolk and yellow color, egg white sticky, bright color, good palatability; its fresh meat, delicious meat, unique flavor, very delicious.

Chai chicken is suitable for free-range farming and stocking on hillside, woodland, wasteland, orchard and field crops. Using a combination of grazing and supplementation, the chickens are allowed to enjoy sufficient sunlight, fresh air and exercise on a wide range of pastures, and feed on a variety of nutritious feed such as grasses, insects, and seeds. Adopting morning grazing and feeding at night

First, feeding and management during brooding

(I) Preparation before entering the chick

1. Disinfection: Thoroughly disinfect the ground, walls, roofs and all utensils in the chicken house. Disinfection must be done carefully and carefully. Disinfection procedures: cleaning → water washing, drying → washing after disinfection, drying → washing after secondary disinfection, drying → formaldehyde fumigation. After passing the inspection, you can enter the chicks.

2. Have all the equipment overhauled to make it work properly.

3. Use poison baits, potions or other methods to destroy rats.

4. Start the heat source at least 24 hours before the chick arrives (at least 48 hours in winter), raise the temperature in the house to 34-33°C, and the relative humidity should not be lower than 60%.

5. The light was set for 23 hours of light, 1 hour of darkness, and the height of the chandeliers was adjusted so that the water fountain was in a bright place for chicks to find.

6. Brooding temperature and feeding density

(b) Picking up

1. Choose strong disease resistance, tender meat, good feed intake, suitable for breeding in mountainous areas. When selecting chicks, you should choose healthy activities, struggle hard, call for crispness, receive good umbilicals, clean feathers, and good uniformity of the chicken. Destroy the chickens and lame chickens.

2. The brooding period is a key stage in the whole breeding process of the chickens. It is particularly important to carry out the rearing of the nursery room. First of all, according to the site and the planned breeding capacity, we must do a good job in the construction of the brooding room. To reduce the occurrence of diseases, we must do a good job in sanitation and disinfection.

3. After the chicks are put into the chicken house, they should provide drinking water (not less than 35°C) and feed as soon as possible. The sink and trough space should be adequate, and the height should be suitable to ensure that each chick can drink water and eat normally, and not drink water. Chicks can be manually assisted.

4. The chicks were prohibited from cleaning the ground within 15 days. Because the chicks had immunity only 14 days after the injection of Marek's vaccine at 1 day of age, chicks could not be protected if they were infected with virulent poisons during this period.

Second, rearing and management of the breeding period

(I) Restocking site construction

1. Seine network. After the stocking site is determined, fences should be fenced and nylon mesh or stainless steel mesh should be used to form a closed fence with a height of 1.5 meters. Chickens can feed freely in the pens to avoid running loss. The area of ​​the fence is based on the number of breeding animals. Generally, each chicken takes up an average of 8 square meters. The fence should be square as far as possible to save on the amount of the net. Seine stocking is also conducive to standardization of the epidemic prevention and purification environment.

2. The establishment of the chicken house. Choose a place with high dryness, good drainage, and a place that is 500 meters away from the road. You can also build a henhouse north and south under tall trees, fruit trees, or woodland. The sheds can be made of plastic greenhouses, which are generally 6 meters wide and the length of which depends on the number of chickens. There is no drip film on the inner layer of the greenhouse. A layer of 5- 10 cm thick straw is laid on top to form a thermal insulation layer. The straw is covered with a plastic film and fixed with a nylon string. The lower edges of both sides of the longitudinal axis of the plastic greenhouse can be rolled up or down to adjust the indoor temperature and ventilation. The floor of the shed can be filled with fine sand to make the room dry, raising 6-8 chickens per square meter. At the same time, multi-layer dove nest nests and habitats are set up, and the size of the egg nests can accommodate 2- 3 Only chickens are appropriate, and soft wheat straw or hay should be placed in advance before laying eggs.

(B) Feeding Management Points

Breeding period is the (31--240 day old) chicks after brooding deferred to the hens start production, cock listing stage, is the key period of chicken growth, therefore, pay attention to the following feeding and management techniques.

1. Stocking season selection. As far as possible after the chicks have been defrosted, they will be stocked at the end of February and early March, when the daytime temperature is not lower than 10°C.

2. Stocking, training and training. In order to return the chickens to the hatchery on time, it is convenient for feeding. When the defrosting chickens are returned in the morning and in the evening, a signal must be given to the chickens to prevent them from being heard when the chickens run away.

Sweetener is a food additive that provides a sweet taste like that of sugar while containing significantly less food energy. Some sugar substitutes are natural and some are synthetic. It allows you to enjoy sweet tasting foods without the extra kilojoules from sugar. It can be beneficial for anyone trying to lose weight and control their sugar intake. Sweetener also does not contribute to tooth decay, as they are not broken down to acid by bacteria in dental plaque.
