Native chickens are also known as grass chickens and stupid chickens. Compared with elite chickens, they have slow growth, low egg production, and high consumption of materials. However, the quality and taste of local chickens is good, and their nutritional value is high, which is in line with the dietary needs of today’s people. Prices are rising, prices are higher, and benefits are better than good breeders. If you can use forest lands and barren slopes for breeding, the income is even more impressive. The method for keeping chickens in the woodland and barren hills is described as follows:
The selection of forest lands, barren slopes, and woodland for construction of sheds and barren slopes should be far away from the urban areas. The hen houses should be built in mountains with high topography, leeward sunlight, relatively flat land, easy protection from animal pests, and easy control of infectious diseases. The shed houses face south and are 1.5 meters to 2 meters high. The size of the hen houses depends on the number of chickens. Generally, 10 to 15 chickens per square meter are used. Temporary chicken sheds and egg nests are used on forest lands and barren slopes to provide eggs for chickens, wind and rain, and water for the day. The brooding house, duty room and warehouse are built next to the chicken house for easy management. A nylon net fence is used around the playhouse to prevent the loss of chickens. The height should not be less than 2.5 meters.
Chicken rearing
The chickens are chicks at the age of 1 day to 40 days. They have rapid growth and development, strong metabolism, poor function of body temperature regulation, poor digestion, difficulty in adapting to changes in outside temperature, and weak resistance to diseases. Therefore, the following points should be made in rearing:
The chicks should pay attention to the ventilation and heat preservation during the transportation of the chicks, and do not be crowded.
When drinking chicks in a timely manner, drink water in a timely manner. Can start to feed some 0.1% potassium permanganate warm water or 5% glucose water, in order to enhance physical fitness, relieve stress, easy to meconium discharge. Drink enough water every day.
After feeding the feeding chicks into the brooding house, they can feed the crushed rice and cooked egg yolk (3 egg yolks per 100 chicks) and feed it every 2 hours. On the second day, feed the compound feed. Reference formula: corn flour 53.2%, bran 8%, bean cake powder 20%, rapeseed cake powder 8%, fish meal 6%, bone meal 2%, shell powder 2%, trace element 0.1%, multi-dimensional element 0.4%, salt 0.3 %, feeding 6 times a day, feeding in strip feeders, feeding unlimited amount, letting them eat.
Temperature, humidity, and light control: 1 day old to 7 days old 33°C to 31°C, 8 days old to 14 days old 31°C to 29°C, 15 days old to 21 days old 29°C to 27°C, 22 days old to 40 Age 27 °C ~ 25 °C, if the temperature does not meet the above requirements, it should be artificially warmed, in the warming process to prevent carbon monoxide poisoning, the relative humidity of 60% to 65%. From 1 day of age, light is maintained for 20 hours to 23 hours per day, and it is reduced to 13 hours to 15 hours after 15 days. Natural light is used after 30 days. illumination
The light is 2 meters away from the ground, 1.5 watts to 2 watts per square meter.
Young chicken rearing
Young chickens between the ages of 41 and 120 days should be divided into males and females for management.
The small rooster feeds the young rooster from 100 days old to 120 days old and weighs 1.25 kg to 1.5 kg. In order to achieve the weight of the slaughter on time, in addition to stocking, it is necessary to provide full-priced feed and allow it to feed. Reference formula: corn flour 60%, bran 10%, bean cake powder 10%, rapeseed cake powder 10%, fish meal 3%, bone meal 1%, shell powder 5.2%, trace element 0.1%, multi-dimensional element 0.5%, salt 0.2 %. Turtles from the 70-day-old to the market requirements fast growth, long fleshy, to eat, eat well, less moving, more sleep, and promote their long fat.
The broiler chickens were reared by the method of small cocks. Laying hens are restricted to feeding, and appropriately reduce the ratio of protein and energy. Reference formula: corn powder 52%, bran 16%, rice bran 14.5%, bean cake powder 5%, rapeseed cake powder 5%, bone meal 1%, shell powder 5.2%, trace element 0.1%, multi-dimensional element 0.5%, salt 0.2 %. Feed 2 to 3 times a day, feed less in the morning, and allow them to have more activities in forest lands and barren slopes, eat more natural forage, feed and insects, feed them at noon or even feed them, and feed them before going to bed at night.
Laying chicken rearing
Increasing feed nutrition, scientific ingredients, and raising protein levels in feed are an important measure to increase egg production in local chickens. Reference formula: corn powder 62%, wheat flour 17%, bean cake powder 6%, rapeseed cake powder 6%, fish meal 4%, bone meal 1%, shell powder 3%, auxin 0.1%, multivitamin 0.5%, salt 0.4% . When the egg production rate reaches 50% to 60%, each chicken feeds 50 g to 75 g in summer and 75 g to 100 g in winter. When the egg production rate is above 80%, the chicken should be allowed to use it without limitation. food. The specific approach is: It is not advisable to feed the chickens every morning. The chickens are free to move on woodlands and barren slopes to eat natural fodder, feed and insects. At noon there are enough materials and water under the shed to allow chickens to eat. When the sun goes down, The chicken retracted the chicken house and fed it.
Create a suitable environment
Practice has proved that the chicken does not affect the laying performance at 15°C～25°C. The egg production rate at 20°C is the highest, and the laying rate below 10°C is severely reduced. Therefore, in the summer, it is necessary to prevent the heat and cool down, do a good job in sanitation, and provide enough clean drinking water for the flock. To keep warm in winter, the chicken's drinking water should be raised properly, avoid drinking ice cold water.
Lighting is an important part of improving the egg production of chickens
The pieces, which can reach 14 to 16 hours a day, have a brightness of 6 to 8 watts per square meter. The color of light is better with red light, followed by white light. Stress is an important reason for the decrease of egg production. To reduce stress, keep the environment quiet. When the breeder is working, the hands and feet should be light. The overalls should be white or blue-gray. Do not use red color. Do not change the color of the overalls casually. In order to prevent harassment of birds and animals, it is forbidden to set firecrackers in order to avoid frightening chickens. In addition, every 4 chickens should have enough nest boxes. The laying boxes should be built in areas where the flock is active so as to avoid grabbing nests when the eggs are laid and disrupting the rules of egg production.
Timely elimination of old chicken
The egg production of native chickens is declining year by year. Although the old chickens are easy to raise, they have few eggs and it is not worthwhile to raise them for a long time. Ordinary chickens are generally sold for one egg production year. Early spring chickens have produced a batch of eggs before the Spring Festival. They can be sold as broilers. The price of chickens is high at this time. Chickens with difficult-to-feed chickens can be forced into moulting when the chickens enter the moulting period of about one year after laying, so that they can resume egg production in advance, continue to use the second year of production, and then sell them as old chickens.
Prevention
Although chickens have a slightly stronger disease resistance in forest lands and barren slopes, they still infect some diseases. Therefore, comprehensive measures must be taken to prevent them. The approach is: 1 day old chicks were injected with Marek vaccine and Newcastle disease attenuated live vaccine, 7 days old to 11 days old were vaccinated with live attenuated Newcastle disease vaccine + H120 transmission, 7 days old to 14 days old with H5N1 subtype of avian influenza Live vaccine or avian influenza - Newcastle disease recombined live double vaccine for initial release, 14-day bursal vaccine for drinking water, 21-day-old H5N1 subtype avian influenza inactivated vaccine for additional boost, 24 days old Newcastle disease IV-line + H120 and bursal vaccine 2 times fluid drinking, 84 days old immunized with live attenuated Newcastle disease vaccine, Escherichia coli vaccine once 50 days and 100 days old, Newcastle disease I line 120 days old + Egg Drop Syndrome + triple bursa of bursa vaccine, comprehensive batch immunization of batches of chickens, injection of Newcastle disease I every 6 months, 130 days of inactivation with H5N1 subtype avian influenza inactivated vaccine. Every 4 months to 6 months, immunization with H5N1 subtype avian influenza inactivated vaccine.
Deworming
The chickens are mainly driven by aphids and coccidia. Local chickens less than 3 months old are most susceptible to infection. They are repelled with 10 mg to 20 mg levamisole hydrochloride per kilogram of body weight and are fed for 6 consecutive days. Repellent coccidiosis is used for every 100 days. Di water 200 liters of water, continuous use of 3 days to 5 days.
disinfection
The chickens are fumigated with potassium permanganate and formaldehyde before being put into the pen homes. When the fowls are fumigated and sterilized, generally 14 ml to 40 ml of formaldehyde per cubic meter, 7 to 21 g of potassium permanganate, and 7 ml of water are used. 21 ml, fumigation 10 hours to 24 hours. The chicken house disinfection should be disinfected once a week and can be sprayed with 0.3% to 0.5% peracetic acid. The sterilized environment should be disinfected once a week and can be sprayed with 2% sodium hydroxide solution.
Benefit Analysis
During the chicken growing season, except for the brooding stage, most of the time was natural stocking, and only a part of the concentrate was added, which greatly reduced the cost of raising the chicken. At present, the price of broiler chickens in the market is 6 yuan per kilogram, while the price of chickens is between 14 yuan and 20 yuan per kilogram. The raising of a 1.5 kilogram chicken costs net income of 14 yuan. 20 yuan. In addition, the soil eggs are also Qiaohuo, each chicken egg production 125, each price of 0.5 yuan (packing and higher prices after the brand), at least gross income of 60 yuan. If a farmer raises 1,000 chickens, the male and the female chickens can make half a year and earn 25,000 yuan a year.
