Chicken farming techniques

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. The adoption of the “high-quality and high-efficiency farming chickens new technology” breeding chickens can not only maintain the characteristics of local chicken meat, but also have a rapid rate of weight gain (1.5 to 2.0 kg in 90 to 100 days). The technical points are introduced below. Varieties choose chickens, that is, 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 to 32°C from 0 to 1 week of age, 31 to 24°C from 2 to 3 weeks of age, 23 to 20°C from 4 weeks of age, and 1 week of age After that, it drops 0.5°C per day. 2. Relative Humidity: The relative humidity in the room is kept at 55% to 65%, that is, 60% to 65% before 10 days, and 55% to 60% after 10 days; the air in the room is kept fresh and has no pungent or smokey 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% dextrose in the initial drinking water for two days; add 0.02% to 0.03% potassium permanganate in drinking water on the third day. 5. High-density brooding. Before 15 days, it is 60-70/m2, and each batch of broods is generally 5,000 (depending on the demand of the farmers for the chicks). The “net, bed, and bulk” combination should be appropriately adapted by the farmer according to the amount he keeps. The indoor floor is required to be cement floor, with windows and windows, so that the air circulation and lighting are sufficient, and a net bed or cage is made. And three-dimensional three-dimensional appropriate. The number of net beds is determined by the number of chickens, which is generally calculated as 45 to 20/m2 (the density is larger in the earlier period). 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 skeleton part of the net bed is made of wood or white bamboo, and the perimeter and bottom of the net bed are fixed with a plastic net of 1 cm 1 cm mesh. Drums and drinkers are placed in a net bed. The garden woodland is surrounded by nylon nets. A pile is hit every 2 to 3 meters. The nylon net is tied to the pile and the ground of the net is compacted by 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, so that the material, water, free to eat. 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 diets with full nutrition, good palatability, easy-to-use broiler full-price pellets, and proper combination with other feed chickens can ensure the normal growth and development of chickens, speed up the rate of weight gain, and keep the flavor of chicken unchanged. Scientifically match the diet. 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% to 10% of whole grain (or wheat) should be added, and 10% to 15% of green feed should be given. During free-range farming in the garden, full-sized pellets of large chickens are used, 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 will be high and the benefit will not be calculated. Secondly, the intermuscular fat of chicken will be more than that and it will not taste refreshing. Third, the unique flavor of soilless chicken will not be enjoyed by consumers. 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 to 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 24 to 28 days old 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. Adding some medicine to feed water can prevent the occurrence of disease. At 2 to 7 days of age, 0.02% of furazolidone and 0.01% of oxytetracycline or penicillin, gentamycin, etc. were added, and these drugs were repeated at 13 to 17 days of age. 19 to 90 days of age in the feed to add chlorobenzene, anti-coccidial anticoccidial drugs such as insect repellent, the house should be cleaned every day, and use quicklime to disinfect the ground and bearing 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.

Fluorine-Containing Phenylamine

Most of the Fluorine-Containing Phenylamine products are a light yellow oily liquid, relatively high density, insoluble in water. Most of them are used in the manufacturing of pesticides and dye intermediates, small part of them can be used as an analytical reagent. The steam or smoke of fluorine-containing phenylamine series is irritated to eyes, mucous membranes and upper respiratory. Vapor and air can form explosive mixtures, in case of fire, high-heat combustion caused the explosion. And oxidant may react. Decomposition by high fever and emit toxic gases. In case of high fever, increased pressure within containers, cracking and the risk of explosion. Protective measures must be done carefully during product storage. Once the fire occurred, it must be immediately evacuated from air leakage,personnel to a safe area, prohibit access to the contaminated area. Recommended emergency personnel wearing self-contained breathing apparatus and wear chemical protective clothing. In the ambulance personnel to ensure proper safety measures, immediately use foam, carbon dioxide, dry, sandy soil to put out a fire.
