Technical Methods and Management Points for Raising Native Chickens in Woodland
How to Use Woodland for Raising Native Chickens
Raising chickens in woodland has three major benefits: First, it improves the utilization rate of land, which helps solve the problem of land competition between livestock development and agriculture. Second, it changes the ecological environment of woodland and orchards and improves ecological benefits. Raising chickens in woodland can effectively promote the combination of forestry and animal husbandry, allowing them to promote each other and develop together. The chickens forage for insects and grass in the forest, and their droppings increase soil fertility, which also benefits tree growth. Third, it improves economic benefits and promotes increases in farmers' income. Raising chickens in woodland requires little investment and is easy to operate, with no need for complicated feeding procedures. The woodland provides a broad and ideal space for the chickens; their range of activity is large, their disease resistance is enhanced, and medication is rarely used in feeding management. In addition, the grass and insects in the woodland provide rich nutrition for the chickens, saving feed and reducing feeding costs. The eggs and chicken meat produced have no drug residues, which exactly suits the high-quality consumption pursued by modern people and is very popular in society. The market price is higher than that of ordinary broiler chickens and eggs, increasing the income of farmers.
To develop woodland chicken raising, the following points should be emphasized.
I. Construction of fences and chicken houses
Build one fence for every 667 sq m of woodland or orchard. The purpose is to prevent the chickens from being lost and from being harmed by natural enemies (foxes, yellow weasels, etc.). The fence should be made of plastic netting or nylon netting 1.5 m high, buried 25 cm deep underground, with a wooden stake driven every 2 m, and the netting tied to the wooden stakes. Bring tap water or a water source into the orchard or woodland. Chicken houses should be built at the two ends of the fence to make it convenient to move the fence during rotational grazing. The chicken house is mainly used for the chickens to rest at night and take shelter from wind and rain, so it can be relatively simple, such as a thatched shed, plastic tent, or asbestos tiles. In winter, the surroundings can be enclosed with straw curtains or plastic film for insulation. The density of chickens in the chicken house is generally 10-12 chickens per sq m. At the same time, inside the house, along the direction in which the chickens enter and leave the woodland, build roosts with a 30 cm slope. The roost materials can be wooden strips, bamboo, etc., spaced about 10 cm apart, so that the chickens can rest on the roosts at night. After the chicken house is built, disinfection should be carried out carefully.
II. Breed selection
Raising chickens in woodland is mainly aimed at pursuing chicken quality and ensuring green, pollution-free products. Generally, local native chicken breeds that are suitable for free-range rearing and have strong disease resistance are the main choice. When these breeds are raised for a period and reach market age, the roosters are generally about 2 kg and the hens about 1.5-1.8 kg.
III. Feeding management
1. Brooding
(1) Preparation before brooding. The brooding room is generally specially built, using a brick-and-wood structure to build an insulated single-story house, or an empty house can be renovated for use. Heating is mainly provided by a stove, and the gas is directly discharged outdoors through a flue. Where conditions permit, infrared heat lamps can also be added to raise the indoor temperature. The brooding room should have ventilation windows, which can both ensure the indoor temperature and help supply fresh air and discharge harmful gases indoors (such as carbon dioxide, ammonia, etc.). The floor bedding can use wood shavings, rice husks, straw, etc. Before each batch of chicks arrives, the site must be disinfected. After the chicks hatch, the bedding and chicken manure should be thoroughly removed, strictly disinfected, and then kept for use.
(2) The introduced chicks must be confirmed to have been injected with Marek's vaccine within 24 hours of hatching. This point is very important and is the key to successful rearing. Chicks should be carefully selected. The main characteristics of healthy chicks are: uniform hatching, even size, normal body weight, smooth and glossy feathers, large and spirited eyes, strong and powerful legs, well-closed navels, soft abdomen, and no fecal contamination around the vent. The brooding period is generally 25-30 days and is carried out in a brooding room with heating function. Some chicks have reduced resistance after long-distance transport, so some vitamins, glucose, and antibacterial drugs (such as enrofloxacin, norfloxacin, etc.) can be added to the drinking water. The density of chicks should not be too high, generally about 40 chicks per sq m.
(3) Brooding temperature is the primary condition for brooding, and suitable temperature is the guarantee for improving the survival rate. Attention should be paid to keeping the temperature even and constant, not fluctuating. When the temperature is normal, the chicks are active normally, spirited and lively, have a good appetite, and drink an appropriate amount of water; when the temperature is low, the chicks make sharp cries, move close to the heat source, huddle and pile up, which can easily cause deaths from piling and crushing; when the temperature is too high, the chicks move away from the heat source, open their mouths and pant, and increase water intake. Therefore, close observation must be paid. Generally, in the first week of brooding, the temperature is 32-34°C (not lower than 33°C in the first three days), then decreases by 3°C each week, and should be kept at 20-23°C in the fourth week. Before release into the woodland, the temperature should be reduced in advance so that the chicks adapt to the external environmental temperature.
(4) First drinking and first feeding. After the chicks enter the house and rest, they can drink water. At first, a small amount of vitamin C, compound vitamin B, and sugar should be added to the drinking water, and the water temperature should initially be 16-20°C. First feeding should be carried out 2-4 hours after the flock drinks water. Mix the feed with a little water, then evenly scatter it on a previously disinfected dark plastic sheet and let the chicks feed freely, feeding small amounts frequently. After 3 days, switch to feed buckets and dry feeding. For first feeding, choose pelleted feed produced by feed mills with stable quality and a good reputation.
2. Management of growing chickens
After temperature reduction, the chicks generally still need to be raised indoors for a period so that they gradually adapt to the external environment. In summer, raise them for 7 days; in spring, 15 days; in winter, 20 days before they can be released into woodland or orchards. Note that the flock should be transferred from indoors to woodland or orchards at night to reduce stress responses. Generally, rearing in spring, summer, and autumn is preferable. In the first few days after release into the woodland, the flock should be trained to form a conditioned reflex, so that they come for supplementary feeding when a whistle is blown. The feed is mainly corn and soybean meal, crushed and then mixed with an appropriate amount of multivitamins and trace elements, stirred evenly, and then put into feed troughs for the chickens to eat. Generally, feed is supplemented once in the morning and once in the evening each day. Pay attention to frequently observing the condition of the flock and solve problems promptly when found.
In addition, raising chickens in orchards can use artificial insect cultivation to supplement part of the animal protein feed and save feed costs. Generally, the rice straw insect cultivation method is used, and the effect is very good. The method is: cut rice straw into 6-7 cm lengths, boil in water for 1-2 hours, take it out and put it into a previously dug rectangular soil pit 0.6 m wide and 0.3 m deep, cover it with 6-7 cm of soil, leftover food, etc., then cover with soil and press firm, splash a basin of rice-washing water or rice soup, etc. every day, and insects can be produced in 8 days. Turn it over and let the chickens peck at them. After they finish eating, cover it with soil again and continue sprinkling rice-washing water, and insects can continue to be produced. At the same time, light traps can also be used to attract insects to feed the chickens, which can reduce crop pest damage and lower pesticide use.
IV. Disease prevention and control
Whether in the brooding stage or the growing stage, immunization and disinfection and cleaning work should be carried out in a timely manner, and prevention and control of some common diseases such as chicken coccidiosis, pullorum disease, and colibacillosis should be strengthened. Two to three kinds of anticoccidial drugs should always be kept on hand and used alternately. Other drugs for preventing and treating pullorum disease and colibacillosis (such as enrofloxacin, norfloxacin, etc.) and conventional drugs such as penicillin should be kept in sufficient quantity, so that timely treatment can be given when disease is found and the survival rate of the flock can be improved. Do not spray pesticides casually in orchards. When fruit trees are sprayed, the flock should be kept indoors, and only after the drug's effective period has passed should they be released into the orchard, so as to avoid pesticide poisoning.
For raising chickens in woodland and orchards, the following immunization program can be used as reference:
Age (days) Vaccine Immunization method
6-7 Newcastle disease and infectious bronchitis combined vaccine (ND+H120+J9 strain) Intranasal and eye drop
13-14 Infectious bursal disease (IBD) Drinking water
20-21 Newcastle disease and infectious bronchitis combined vaccine (ND+H120+J9 strain) Intranasal and eye drop
25 Infectious bursal disease (IBD) Drinking water
40-45 Newcastle disease strain I (ND) Intramuscular injection
Prevention and treatment of several common diseases:
1. Pullorum disease
Pullorum disease is an infectious disease caused by Salmonella pullorum. It mainly affects chicks, and both morbidity and mortality are very high. Adult chickens can also be infected, but the symptoms are mild or inapparent, mainly affecting organs such as the ovaries, follicles, oviduct, and testes. The incubation period of this disease is 4-5 days. Chicks begin to develop the disease at 5-6 days, and the second to third weeks are the peak period of morbidity and death. The manifestations are listlessness, dirty and messy feathers, drooping wings, shrunken head and neck, not eating or moving. Because body temperature rises and they fear cold and shiver, they often huddle together or stand dully to one side; they excrete foul-smelling white pasty diarrhea that sticks to the feathers around the vent, forms lumps, and may even block the vent so that feces cannot be passed; they make chirping sharp cries. If the bacteria invade the lungs and cause pneumonia, the sick chickens have difficulty breathing and pant with open mouths. After illness, they often die from weakness and exhaustion. Adult chickens infected with this disease generally show no obvious symptoms. Prevention and control of this disease: brooding is the key. Try to purchase chicks free of pullorum disease, carry out strict disinfection, and do a good job in cleaning and disinfecting the floor, equipment, forage, cages, drinkers, etc. in brooding and growing houses. Strengthen the feeding and management of chicks. Temperature, humidity, ventilation, and light should be strictly controlled. Pay close attention to flock dynamics, and sick chickens with pasted vents should be isolated or culled in time. In the first few days of brooding, enrofloxacin can be appropriately added to drinking water. When disease occurs, drugs such as compound poultry antibacterial powder, potent ciprofloxacin, norfloxacin, and gentamicin can be used for treatment, with good results.
2. Chicken coccidiosis
Chicken coccidiosis is a common intestinal parasitic disease. The incidence is highest in chicks aged 15-50 days, and the mortality rate can reach more than 80%. Common symptoms: listlessness, reduced appetite, dirty and messy feathers, closed eyes and standing dully, drooping wings, diarrhea, etc. The most diagnostically characteristic symptom is bloody feces. Necropsy shows enlargement and congestion of the small intestine and ceca. Prevention and control of this disease should be carried out early. Usually change the bedding frequently and prevent feed and drinking water from being contaminated by feces. Disinfectant can also be used for disinfection with chickens present. When disease occurs, anticoccidial drugs such as diclazuril or sulfonamides can be used for treatment, with medication for the whole flock, and coccidiostats should be changed frequently to prevent drug resistance.
3. Chicken colibacillosis
Chicken colibacillosis is an infectious disease caused by pathogenic Escherichia coli. Chickens of all ages can develop it, but it is more common in chicks and young chickens aged 6-10 weeks. Clinically, it is mainly secondary infection and often mixed with infectious bursal disease, chronic respiratory disease, pullorum disease, Newcastle disease, ascites syndrome, etc. Dense flocks, turbid air, excessive cold or heat, malnutrition, and unclean drinking water are all major predisposing factors. The main clinical manifestations are: acute septicemia and airsacculitis, pneumonia, enteritis, etc. Sick chickens show listlessness, dirty and messy feathers, shrunken neck and standing dully, diarrhea or loose stools, sometimes difficulty breathing, and yellow, green, or grayish-white feces. Necropsy lesions mainly include congestion, blood stasis, and degeneration of internal parenchymal organs, often with some white fibrinous membranes attached, enlarged spleen appearing purplish-red, fibrinous pericarditis, turbid pericardial fluid, inflamed peritoneum, and swollen joints in some chickens. This disease should focus on prevention, do a good job in environmental sanitation, strengthen feeding management, and do well in the prevention of infectious bursal disease, Newcastle disease, and other diseases, which can reduce or lower the harm of this disease. Appropriately adding antibiotics to the feed during the brooding period is beneficial for controlling this disease. Because Escherichia coli easily develops drug resistance, sensitive drugs should be selected for treatment, such as loperamide, enrofloxacin, gentamicin, tetracycline, potent norfloxacin, oxytetracycline, potent ciprofloxacin, etc., and the dosage should be sufficient, ensuring continuous medication so that the effective drug concentration is maintained in the body for a certain period.
Raising chickens in orchards and woodland is a good short-term, stable, and quick sustainable development project. It is a new thing under the adjustment of the rural industrial structure and a good path for farmers to increase income, escape poverty, and become prosperous. It should be combined with agricultural structural adjustment to increase the scale of promotion.
