The chickens raised in rural areas are of good quality and fresh taste, and are deeply loved by consumers. However, due to its slow growth rate (5 months before it grows up), there are not a lot of sporadic free-range farmers, so the overall economic efficiency of farmers is not high, and it is difficult to increase income. How to change this situation and develop the rural chicken industry so that the chickens grow faster and have better meat quality. Adopting the “high-quality and high-efficiency farming of chickens†to breed chickens can not only maintain the characteristics of local chickens, but also have a faster rate of weight gain (1.5 to 2 kilograms per day for 90 to 100 days). If farmers farm more chickens, each A chicken can make a profit of 8-10 yuan. The technical points are now introduced in the following: Variety selection Local chickens, namely local chickens, some called grass chickens. As the breeds cross each other, the feathers of the chicken are black, red, yellow, white, and hemp. The skin of the feet is also yellow, black, gray, etc., and the market consumption is also different. Therefore, it is necessary to select and breed varieties that are suitable for the local consumer market. For Guangdong, three yellow chickens, apricots, and chickens are good varieties. Greenhouse brooding The “three-dimensional net bed†brooding greenhouse was established to conduct specialized scale brooding. The peasant households raised the survival rate of the chickens with high survival rate, low risk and easy to succeed (when brooding can be started from brooding). There are several main points in brooding: 1 Room temperature: 35-32°C for 0-1 week old, 31-24°C for 2-3 weeks old, 23-20°C for 4 weeks old, or after 1 week old Drop 0.5°C daily. 2Relative Humidity: The indoor relative humidity is kept at 55%-65%, which is 60-65% 10 days ago, and 55%-60% after 10 days; the indoor air is fresh, no pungent, smoked eyes. 3 Supplemental lighting: The first 5 days of light can be maintained for 23 hours a day, followed by 17 hours of light (including natural lighting). 4 Drink water and eat food in time. Chickens should eat and drink as soon as possible, and they should be able to feed and water continuously and eat freely. Add 5% glucose in the initial drinking water for two days; add 0.02%-0.03% potassium permanganate in drinking water on the third day. 5 high-density brooding. It is 60-70/m2 before 15 days, and generally more than 5,000 broods per batch (depending on the farmers' demand for chicks to determine the brood size). The combination of "net, bed, and bulk" should be adapted appropriately by the farmer according to the amount he keeps. The indoor floor is required to be concrete floor, with windows and windows to allow sufficient air circulation and lighting. And make a net bed or chicken cage, three-dimensional three-dimensional appropriate. The number of net beds is determined by the number of chickens, which is generally calculated as 45-20 pieces per square meter (previous density is larger). The first layer of the net bed is 40 centimeters above the ground, the height of the net bed is 30 centimeters, and the distance between the upper and lower layers is 20 centimeters. The top of the first and second layers of the net bed should be placed on the top of the dung sheet (a three-layer board is available), and the skeleton part of the net bed is used. The wood or white bamboo is fixed around the bottom and bottom of the net bed with a plastic net of 1 cm 1 cm mesh, and the material bucket and the water fountain are placed in the net bed. The garden woodland is surrounded by nylon nets. A pile is hit every 2-3 meters. The nylon net is tied to the pile and the ground of the net is compacted with soil. The area of ​​the surrounding area is generally calculated at not less than 1.5 square meters per bird, and the wider the better. The back-fed chicks (having brooded chicks) are brought to bed in a net bed at a weight of 1 kg, and stocked in the surrounding forest lands from 1 kg to slaughter (rainy days and frosty days) Into), feeding, water, feed, feeding freely. Feeding in a net bed, the range of chickens is small, the energy consumption of the chicken body is small, and the weight gain is accelerated; the chickens are scattered in the surrounding woodland of the hospital, can catch wild weeds and biological insects, change the food structure, and have a high meat quality. Meaty taste). The combination of dietary supplements with full nutrition, good palatability, and easy consumption of broiler full-priced pellets, in combination with other feed chickens, can ensure the normal growth and development of chickens, and accelerate the goal of constant weight gain and constant chicken flavor. Therefore, it is necessary to collaborate with the diet scientifically. During the brooding period, full-grain pellets of broilers should be used. When the food is first eaten, the feed must be soaked and transformed, and then chopped by hand. During the heat-removal period of chickens up to 1 kg in weight, medium-strength chickens are used. They should be gradually replaced when they are replaced, and they must not be replaced at one time to avoid stress. At the same time, 5% -10% of whole grain (or wheat) should be added, and 10% -15% of green feed should be given. During free-range gardens, large chickens are used as full-priced pellets, and 10% to 15% of whole grain (or wheat) is added to the diet and 15% to 20% of green feed is added. If the light feeds the full-priced feed, the cost of feeding is high, and the benefits are uneconomical. Secondly, the intermuscular fat of chicken is much, and it is not refreshing to eat. The third is the unique flavor of soilless chicken that consumers do not like. Adding a proper amount of green feed can increase the vitamin content. Second, it can reduce the cost of breeding. Third, it can reduce the intermuscular fat content of chicken. Disinfection and immunization Prepare chickens for immunization, disinfection and epidemic prevention to prevent the occurrence and spread of infectious diseases. This is the key to the success of large-scale chicken breeding. Therefore, we must do a good job of immunization and disinfection and epidemic prevention, reduce the death of chickens, and increase the survival rate and commodity rate. The immunization procedure for chickens should be based on the nature of the production (commercial broiler chickens). It is best to refer to the broiler's immunization procedure. One-day-old chicks should be immunized with Marek's vaccine. This is mainly done in the hatchery; 6-7 days old chickens are immunized with a mixture of drinking water such as chicken Newcastle disease IV strain (or V4 seedlings), bursa of B87 vaccine, and H120 seedlings; Newcastle disease II is used at 24 to 28 days of age. The vaccine was used once to immunize the seedlings; it was injected once again at the 60th day of the chicken Newcastle disease I strain and was not vaccinated afterwards. At the same time, add some drugs in feed water to prevent the occurrence of diseases, add 0.02% of furazolidone and 0.01% of oxytetracycline or penicillin, gentamycin, etc. at 2-7 days old, repeated at 13-17 days of age. Use the above drugs; 19-90 days of age in the feed to add chlorobenzene, anti-coccidial anticoccidial drugs, insect repellent, clean the house every day, and use quicklime to disinfect the ground and the feces board. Each half of the use of mixed phenolic water will be outside the spray disinfection, killing the poultry house with chicken poisoning. After the slaughter, the site must be completely cleaned, rinsed and sterilized; the disinfectant pool at the door of the henhouse should always have lime or disinfectant, and pay attention to changing.
