Technical implementation scheme of raising chickens under the forest

Forest chicken is the use of traditional chicken breeding methods, combined with modern scientific breeding technology, make full use of forest resources (insects) chicken and obtain low-cost, environmental protection, green poultry products. Let's take a look at the implementation plan of chicken technology under the forest.

1. Construction of chicken coops in the woods

Choose a place with good ventilation, sunny and drainage conditions, traffic and epidemic prevention conditions meeting the requirements, good growth of surrounding trees, 10-20 meters long and 1.5-6 meters wide open space in the middle, build simple sheds easy to dismantle and move with bamboo, wood, film and other forest materials, and its construction can be made from local materials.

1, with adobe, bricks, oil chain paper, wheat knot or wood to build a 10 meters long, 1.5 meters wide, 2 meters frame, and in the middle open a door about 1 meter.

2. Use old plastic woven bags and thick black plastic film to enclose the periphery and top, cover and fix.

3, habitat with bamboo, wood or street branches to 2 cm with the laying, 30 cm from the ground.

Each shed can raise 300 chickens, one to several sheds can be built according to the word breeding capacity, and management rooms and ingredient rooms can be set up nearby.

2. Selection and breeding techniques of brooding chickens

30-day-old meat offal or commercial laying hens introduced in regular farms are directly put into woodland for breeding, and young chickens newly hatched can also be introduced into hatcheries for breeding until they are out of temperature and then put into woodland for grazing and breeding.

Brooding should pay attention to the following requirements:

One is the appropriate temperature, generally required to brood the first week temperature of 32-35℃, after the weekly drop of 2-3℃ until 20-22℃, relative humidity of about 60%, higher in the early stage, lower in the late stage.

Second, good ventilation, warm at noon when the window ventilation, ventilation to prevent cold invasion, in case of cold.

The third is the appropriate density and population. Generally, 20-25 chicks per square meter are raised on the ground at 0-4 weeks of age, 10-19 chicks at 5-7 weeks of age. Generally, the chick population should not be too large, and 200-300 chicks are appropriate.

The fourth is the correct lighting, the first 3 days after the chicks are housed, 24 hours of light, gradually reduced later, 4-7 days of age to maintain 15 hours, from the second week after the day is not less than 8 hours, the light intensity to 0.6 watts per square meter area, the bulb from the ground about 2 meters is appropriate.

Fifth, the use of complete feed, you can buy regular feed manufacturers produced by meat chicken brooding complete feed direct feeding, you can also buy concentrated feed or premix according to the instructions after feeding.

Sixthly, carefully feed, chicks should be allowed to drink 5% sugar water freely within 3 hours after entering the house, and add 1/10,000 high manganese carbon potassium, water temperature 17-18℃. Once in the morning and once in the evening, after the uninterrupted supply of warm boiled water, feed particle size should be fine, and now feed, 0-7 days old 6-8 times a day, 7 days old after 4-6 times a day, frequently add less feed.

3. Feeding methods of chickens in the forest:

Generally, chickens are allowed to enter the forest land between Qingming and grain rain, i.e. in the middle of April, and leave before the end of October (after processing the last batch of chickens). In this way, if they breed their own chicks, they should introduce chicken seedlings in March, and gradually leave the temperature and enter the forest when they are 20-30 days old. The breeding density should be rather sparse than dense. There are usually no more than 100 per acre. In order to make the weight of chickens reach the market standard of more than 2 kg at the age of 100-120 days, complete feed should be supplied at the same time of stocking. The reference formula ( %) is as follows: corn 51.7, wheat bran 12.0, soybean meal 15.0, sesame oil residue 8.0, bone meal 3.0, pea 10.0, salt 0.3. Feeding during stocking period should follow the principle of "early less, late amount", and consider the characteristics of poor foraging ability of young chickens, feeding as appropriate, to achieve a small amount of frequent addition, avoid leftover in the tank, pay attention to the chicken according to the strength of the group, batch stocking, stocking scale to 800-1000 per group (i.e. 3 shed chicken quantity) is appropriate, too large is difficult to manage, too small cost is high, low income. Blow whistle before feeding each time, so that chickens form the habit of whistling and eating. Add a small amount of green feed to the feed before stocking, so as to avoid stress caused by sudden intake of green feed when chickens graze. Then choose sunny and warm weather for trial grazing. The starting time is shorter, and then gradually extend the time, so that chickens can gradually adapt to grazing. The grazing place should be from near to far, and the range should be gradually expanded. However, the range of grazing chickens should not be too large to improve the feed utilization rate of chickens. Available screen fence separation, both to limit the scope of chicken activities, easy to put in different places, but also to prevent chicken escape and animal invasion. In the process of grazing, special personnel shall be assigned to be responsible for paying close attention to the weather conditions. In case of sudden weather change, chickens shall be rushed back to the shed in time. In summer, they shall be released more in the morning and evening. They shall rest in the shade at noon or rush back to the shed. They shall not be kept in the scorching sun for a long time to prevent heatstroke.

IV. Epidemic prevention and disinfection techniques for chickens in the forest

The scientific immunization program should be formulated as follows: 1-day-old chicks injected with Malik vaccine, 9-day-old chicks injected with Newcastle disease II strain H120 nasal drops, 14-day-old chickens drinking twice as much bursal disease vaccine, 25-day-old chickens injected with Newcastle disease oil vaccine, 45-day-old chickens drinking twice as much bursal disease vaccine to strengthen immunity. Comprehensive immunization of each batch of chickens shall be implemented, and the feeding mode of all-in and all-out shall be adopted. Each batch of chickens shall be thoroughly disinfected after sale. Centralized disinfection treatment shall be carried out on the cleaned chicken manure.

5. Precautions for raising chickens in the forest

Raising chickens in the woods looks simple and easy, but scientific feeding management is still very important.

First, personnel arrangement should be fully considered. When special personnel cannot be fixed, it is necessary to determine who is the main one to clarify responsibilities. Patrol and observation should be strengthened when stocking. If sick chickens with slow movement, isolation and listlessness are found, they should be isolated and treated in time.

Second, careful planning, full preparation, according to the forest area to estimate the number of feeding, arrange feeding intervals, batches, prepare necessary drinking and feeding utensils and feed, do well, avoid passive and temporary improvisation.

Third, the cost should be calculated at any time. Although the forest land can be stocked with food such as Cordyceps sinensis, it mainly depends on feed. Therefore, feed still accounts for a considerable proportion of the cost. When the cost accounts for a low proportion of the chicken price, it should be considered to sell it as soon as possible.

Foreground for chickens

Woodland chickens are popular with consumers because of their wild food, extensive exercise, sufficient light, long breeding time, strong and beautiful body shape, strong flexibility of meat, proper fat deposition, tender quality, delicious and pure taste, and have broad market prospects.

Raising chickens under forest not only saves feed cost, but also eliminates pests and cultivates soil for garden plot and improves output value per unit area of land. It is a development mode of ecological circulation, combination of planting and breeding, and harmony between forest and animal husbandry. Therefore, woodland chicken is not only a kind of high quality, but also a breeding concept and production mode, the essence is "high quality, high efficiency, ecology and safety".
