I. Characteristics Three yellow chickens are high-quality broiler strains that have been bred through the breeding of good local breeds. They have yellow feathers, yellow skin and yellow leg ridges. Compared with broilers with white feathers, Sanhuang chicken has a slower growth rate and a longer feeding cycle. However, Sanhuang chicken has a delicate meat quality, thin skin, moderate amount of intermuscular fat, and delicious meat taste. Therefore, it is welcomed by consumers in the market. The price is higher. Second, feeding methods Three yellow chickens are mainly raised on the ground with thick litter, flat on the Internet two. 1. The method of raising the thickness of litter on the ground: The way to raise the thickness of litter on the ground is to lay about 10 cm thick litter on the ground in the chicken house. The chicks have been living from the house until they are listed for sale. This is the most commonly adopted method of rearing. The thick bedding on the ground requires dryness, softness, strong water absorption, and no mildew. Commonly used litter includes shavings, sawdust, rice hulls, and straw, straw, and corn stalks that are 3-6 cm long. It is better to use these kinds of dumbs for mixing. The advantage of the thick litter raising method is that it is simple and easy, the equipment investment is small, and the defective product rate is low; the disadvantage is that broilers are susceptible to intestinal diseases and coccidiosis, which increases the cost of medicines. 2. The method of raising the Internet on the Internet is to set up a rack at a height of 50-60 centimeters from the ground, and use a round bamboo or wooden strip of about 2 centimeters thick to make a net bed on the rack and lay it on a plastic net. Or barbed wire, chickens live on the Internet. Although this method has a high investment in equipment, because the chicken droppings are on the ground and the chickens do not come into contact with chicken droppings, the incidence of diseases such as coccidiosis, colibacillosis, and chronic respiratory diseases in chickens can be significantly reduced, and medical expenses can be reduced. The environment in the house is easy to control and also saves the cost of litter. 3. Chicken coops and equipment 1. Chicken coops: The chicken house requires good insulation properties of the ceiling and walls. The ground requires a cement floor and a slight slope. This facilitates flushing and disinfection. The walls of the house are equipped with air inlet and outlet windows. hole. 2. Chicken-raising equipment: Chicken-raising equipment includes insulation equipment, breeding equipment, and lighting facilities. Insulation equipment: stove, insulation umbrella, infrared light. Breeding equipment: trays, buckets and drinking fountains. The tray is for use by 1-8-day-old chicks when they eat, and one for every 80-100 chickens; it is gradually changed to a drum after 9 days of age. The diameter of the hanging bucket is 38 cm, for every 100 Chickens need 3 hanging buckets. There are two types of drinking fountains, portable and hanging. For chicks aged 1 to 8 days, use a portable waterer with a capacity of 0.5 kg. One for every 70-80 chickens; replace it after 9 days of age. Medium-sized drinking fountains, with a capacity of 2 kg, provided for every 70-80 chickens; one for every 125 chickens if using a hanging drinking fountain; for drinking water at an automatic drinking trough, 2 for each chicken cm. Illumination facilities: A lamp cap with a lampshade is installed every 20 square meters, and each lamp head is prepared with one bulb of 40W and 15W. A 40W bulb was used for 1-6 days and a 15W bulb was used after 7 days. Enclosure: During the early period of brooding, in order to prevent the chicken from getting cold from the heat source, a thick cardboard or mat can be used around the warming umbrella. The retainer is 15 cm high and the distance from the edge of the warming umbrella is 70-150 cm. Enclosures gradually expanded from the third day and were removed on the seventh day. IV. Feeding Technology 1. Adequate drinking water is one of the essential nutrients for Sanhuang Chicken. Throughout the breeding process, the amount of water consumed by the chicken is approximately 2-3 times the amount of feed consumed. The higher the temperature, the greater the amount of drinking water. Adequate and sanitary drinking water supply is an important guarantee for successful broiler feeding. After entering the house, the chicks are required to artificially guide the chicks to drink about 5% sugar water at 20°C. The chicks can drink water for 2-3 hours before they start eating. The temperature of the chick's drinking water in the first week should be at 20°C, and a certain amount of soluble vitamins can be added, such as rapid filling --- 14, electrolysis multidimensional and so on. The number of drinking fountains should be sufficient, and should be placed evenly. The height of the drinking fountain should also be gradually adjusted along with the growth of the chicks so that the edge of the drinking fountain maintains the same height as the back of the chicken to prevent the overflow of the drinking water and keep the padding dry. The drinking fountain should be kept clean and cleaned and disinfected daily. 2 times. 2. Rich nutrition The growth of three yellow chickens requires rich nutrition. The feed for the three yellow chickens requires complete nutrition, and any deficiencies or lack of trace ingredients may cause pathological reactions; the second is the requirement of high energy and high protein; the third is the requirement of feed. The proportion of various nutrition in the fit. Three yellow chickens are generally divided into two stages, 0-28 days of age as the brooding stage, and 29 days of age—known as the fattening stage. Therefore, the feed supply of the three yellow chickens should be divided into two stages. The feed for the brooding stage should be generally used as flour. Feed or processed into granules, feed for the fattening stage is best to use pellet feed. Three yellow chickens were fed on the free-feeding method. At the age of 1-3 days, in order to allow the chicks to learn to feed as soon as possible, feed once every 2-3 hours; feed once every 4 hours for 4-28 days; and 4 times daily after 29 days of age. Multiple feedings can stimulate the appetite of the chicken and increase the feed intake of the chicken. Each time the material is fed, the amount of feed should be controlled so that each chicken can feed and there will be a small amount of excess material. Too much material will be wasted by the gizzard discharging bucket. One-day-old chicks were fed on an open tray. After 7 days of age, the chicks were gradually fed with a barrel. After the 12th day of age, the chicks were completely fed with a bucket. The height of the bucket is adjusted to the growth rate of the chicken and kept at the same level as the back of the chicken so as not to feed the feed. The bucket must be sufficient and distributed evenly. In the conversion from chicken material to fertilizer, it takes about 5 days to gradually change, and cannot be changed suddenly. Keepers should accurately record the amount of feed each day. 3. Good environment Three yellow chickens require a temperature of 32-34°C for 1-2 days, then the ambient temperature can drop by 3°C after each week, and the ambient temperature should be 20-21°C after 5 weeks of age. The minimum must not be less than 16°C. During the brooding period, the temperature in the house can fluctuate by 1-2°C per day, resulting in an appropriate temperature difference, which can stimulate appetite, increase feed intake, and promote chicken growth. During the first week of brooding, a slightly high humidity of 56-70% was maintained in the house to prevent dehydration of the chicks, affecting health and growth. After two weeks, the humidity in the house was controlled at 55-60%. By strengthening ventilation, avoid water leakage in drinking fountains and prevent litter from getting wet, etc., and keep the house dry. Pay attention to the ventilation of the coop, eliminate the dirty air in the house in time, and the amount of ammonia in the house should not exceed 20ppm, which means that people do not feel pungent. To solve the contradiction between ventilation and ventilation, it is usually 1-2 weeks old when the main insulation, proper attention to ventilation, must prevent cold air directly to the chicks. At the age of 3 weeks, ventilation volume and ventilation time should be gradually increased. After 5 weeks of age, ventilation should be the main method. 4. Appropriate illumination of three yellow chickens requires proper lighting, the purpose of which is to prolong the intake time, increase food intake and speed up growth. Usually 1-2 days old with 24 hours of light, 3 days after the light for 23 hours a day, night off for 1 hour to keep the dark, so that the chicken can adapt to environmental changes during a sudden power outage, to prevent the accumulation of chickens cause death. The brightness of light is stronger in the first week of the brooding period, with 2-3 watts per square meter of ground and 0.75 watts per square meter after the second week, preventing excessive activity or occurrence of paralysis. Conditions can also be used 1-2 hours of light, 2-3 hours of dark lighting. In addition, attention must be paid to observing the behavioral spirit, feeding, feces, and breathing of chickens. When abnormalities are found, the cause must be identified and measures must be taken. 5, the appropriate density to ensure that every three yellow chickens occupy the necessary ground area at different stages of growth, so that it maintains the proper density from start to finish, this is a key to success or failure of three yellow chickens. The concept of "breeding density" includes three aspects: First, how many chickens are raised per square meter; Second, how many troughs are occupied by each chicken; Third, how many drinking positions each chicken has. These three aspects are indispensable. The breeding density of three yellow chickens is usually calculated based on the number of chickens per square metre sold. The breeding density is 11-14 feathers per square meter when adopting the method of raising the ground with thick litter, and 14-16 feathers per square meter when adopting the online level raising method. 5. The disease-preventing and controlling period of the three yellow chickens is short, once any disease occurs It has to be controlled and it is often too late to recover before it is sold. Therefore, it must be based on hygiene and epidemic prevention, and the concept of "prevention from over control" must be adopted. 1. Implement the "all-in, all-out" system: In the same chicken house or chicken farm, only enter the same batch of chicks at one time, keep the chickens of the same age, and be present on the same day. After the appearance, thoroughly sweep, clean, disinfect, and then The shed was closed for more than one week and then the next batch of chicks was raised. Since there is no opportunity for cross-sense of different age groups in chicken farms or chicken houses, the epidemic links of infectious diseases are cut off, thus ensuring the safe production of chickens. 2. Do a good job of disinfection: Thoroughly sterilize the house and equipment; Personnel and vehicles should be disinfected; Disinfect the chickens at least once a week, regularly clean and disinfect the environment around the house, and strengthen litter management. Keep the litter dry and free of mildew. 3. Formulate an appropriate immunization program: Infectious bronchitis H120 or Ma5 vaccines are used for 1-3 days of age; intranasally or intraocularly for 7 days with Newcastle disease Lasota or Clrone-30 or II; Seedlings D-78 drinking water or drops; 26-28 days old, Newcastle disease Lasota or Clrone-30 seedlings 2 times the dose of drinking water. If necessary, drink water again at the 35-day old French capsule D-78. Alternatively, one day of age with new branch double seedlings ND-H120 or ND-Ma5 eye drops or nasal drops, while the Newcastle disease oil emulsion seedlings in the lower third of the neck, dorsal subcutaneous injection of half a dose of 0.2ml /Feather; 14-day old Dow D-78 drinking water or drops; 32-35 days of age and then use of the sac of drinking water once. 4. Prophylactic dosing in drinking water or feed: The use of antibiotics to prevent doses from being intermittently added to drinking water or to prevent the occurrence of some bacterial diseases.
