Breeding technology of free-range native chicken

Free-range native chickens in rural areas are deeply loved by consumers because of their health, delicacy and rich nutrition. Free-range native chicken has always been a feature of rural breeding industry, and the prospect of consumption is very broad. Next, let's take a look at the breeding techniques of free-range native chickens.

First, choose a suitable breeding ground

The native chicken breeding site should be kept at a considerable distance from the main residential areas, water sources, trunk roads, etc.; the chicken coop should be in a flat position with leeward facing sun, sitting north and facing south, and easy ventilation. Plastic sheds can also be built for rest; chicken sheds can be transformed from old houses or built separately; plastic nets with elastic mesh diameter of l0mm can be installed in small or medium chicken sheds, and the distance between the ground and the net is about 9-l0m. If the chicken coop is transformed from the old house, it is necessary to set up daylighting windows about 1.5m from the ground and floor windows about 0.2m from the ground in the front and rear positions.

II. Feeding and management of native chickens

1. Prepare the chicken coop

For the chicken house transformed from the old house, the four walls and tops of the house should be fully cleaned, and the house should be painted twice with concentrated limestone water, and then fumigated with formalin and potassium permanganate; bedding grass, pellet feed and feeding utensils should be fully disinfected.

2. Choose chicks

In order to prevent exotic chickens from bringing germs and ensure the purity of native chicken breeds, it is appropriate for self-breeding chickens and self-breeding chicks.

3. Choose breeder chickens

When selecting breeder chickens, we should pay more attention to their coat color, growth rate and health degree, and the pure native chicken with bright coat color, fast growth rate and strong body is suitable, the weight of rooster should be L 5-2 lkg, the weight of hen should be above and below 1.5kg, and the proportion of rooster and hen should be 1:10.

4. Hatching chicks

When hens hatch chicks, the age of chicks should be as close as possible; if raised on a large scale, they can choose to hatch in an incubator.

5. Brooding management

(1) feeding density: the feeding density of chicks can refer to the following standards: 50 / m2 in the first week, 40 / m2 in the second week, 30 / m2 in the third week, and then 10 / m2. In addition, the plastic net should be evenly covered with a layer of clean straw, which should not be too thick to prevent chicken droppings from falling to the ground, and the bedding grass should be removed in the third week.

(2) temperature: 32C in the first week, then decreased by 3C per week until the temperature reached the natural temperature.

(3) Light time and intensity: in the first week, 60W incandescent lamp was used for 24 hours, and in the second week, it was reduced to 18 hours. In the third week, the natural light time was taken as the standard, and no artificial light was needed.

6. Chicks drink and eat

The first drinking water after the chicken comes out of the shell is "boiled drink". 10 cracked glucose or 8% brown sugar water can be added to its drinking water, and vitamins can also be added to enhance its physique and disease resistance; the first feeding of the chicken after coming out of the shell is "eating". It can be "eaten" only 3 hours after the chick "starts drinking". The feeding amount of each animal was 4: 59 and increased gradually, with less frequent feeding and 6-8 times per day.

7. Stocking

Chickens need to be trained artificially at the beginning of their stocking, and they can be trained to look for food by throwing feed, artificial driving, whistling and so on. After training for about lOd, chickens will form a conditioned reflex and look for food freely.
