Sanhuang beard chicken has a high value in modern chicken breeding, production, and foreign trade markets. Sanhuang beard chicken, as an outstanding local chicken species with outstanding meat quality, has been improved in its performance and has been vigorously promoted to produce high-quality San Huang beard commercial chickens in an intensive manner, and actively realizes the industrial development and utilization of this fine breed of resources. It is necessary. Therefore, relying on the College of Animal Science of South China Agricultural University, Saitefa High-tech Agricultural Development Co., Ltd. implemented the "Harvest Plan" project of the Ministry of Agriculture in Zijin County, Guangdong Province - "The Promotion of Comprehensive Supporting Techniques for High Quality Sanhuang Bearded Chicken". In the implementation of the project, relying on leading enterprises, adopting the form of “company + farmer householdsâ€, implement the “four provide one recovery†operation mode for chicken farmers (ie, provide chicks, feed, medicine and technical services, and return the price of broiler chickens for slaughter). . In the two years, a total of 359.96 million chickens with three yellow beards were promoted, and 34.71 million broilers were slaughtered. The average age of broilers was 115 days. The average slaughter rate was 965 percent, and the average slaughter weight was 146 kg. The output value of chicken production was 658.796 million yuan, and the total income of chicken farmers was 763.62 million yuan. After two years of implementation, the promotion tasks specified in the contract have been completed, and certain economic and social benefits have been achieved. The third prize of the Guangdong Provincial Agricultural Technology Promotion Award was obtained. In order to provide the reader with a better understanding of the feeding and management methods of San Huang beard chicken, the main points are described below. Observation of the flock 1 When feeding in the early morning and adding water, observe the mental state of the flock and the condition of the feces. If sick chickens are found to have runny nose, tears, swelling of the face and difficulty in breathing, etc., isolate or eliminate them in time. Healthy chickens are lively and responsive, and they cry crisply; chickens are depressed, sluggish or dormant, and loose. Normal chicken droppings are gray and have white urate adherents. 2 At night, listen to the abnormal sound of respiratory diseases in chickens, especially in the winter, due to poor ventilation, it is easy to cause respiratory diseases. If there are snores, panting, coughs, etc., it is necessary to isolate in time and treat alone. 3 Pay attention to changes in the temperature of the house, especially in the winter without drafts, thief, etc. 4 Observe whether there is any chicken or not, if it is found that it should be singled out in time, use purple syrup to wipe off the blood color, and find out the reasons in a timely manner, whether the weather changes, the density is too large, poor ventilation, light is too strong, symptomatic treatment. Feeding Technology 1 Drinking Water: Provide enough clean fresh water. Always add water to the drinking fountain. 2 Feeding: The drums should be evenly distributed, and the drums and trays should be cleaned regularly. After the material in the drums is finished, take out the drums so that the chickens can eat more material in the net trays; provide full-priced compound feeds. The drums and trays should be regularly cleaned and disinfected once a week. There should be no chicken droppings and other dirt inside. If you mix wet materials, don't mix them too much. Take the chickens for a half an hour to finish. , And then to clean the eating utensils, so as to avoid the acidity of the remaining wet material cause chicken disease; high temperature and humidity season, pay attention to whether the feed observed when the feed cake, taste change phenomenon, pay attention to moldy feed can not be fed. 3Fattening: If the chickens are not fat enough in the late period (ie 20 days before the listing), they can buy some pig fat and oil in the market and mix them with lard to feed. The oil dregs can also feed chickens. Generally, 1 packet plus 2 - 3 pounds of lard. 4 When the uniformity is poor, it can increase the amount of each feeding and reduce the number of feedings. 5 Regularly disinfect chicken farms and chicken utensils, prevent them from being cured, and pay attention to temperature changes to prevent chickens from catching colds and respiratory diseases. Environmental Hygiene 1 Keep the ground clean and dry, especially in the summer, the chicken manure water content is about 8%, so that the humidity inside the house is large, affect the heat dissipation, and should be promptly removed. 2 Clean chicken manure once every three or four days, no more than one week at most, rinse once a week with conditions, note that after each cleaning, you must disinfect once with disinfectant (such as 100 toxin, etc.), or you can use quicklime. Do not disinfect with pesticides. 3 The collected chicken droppings are kept away from the chicken farm and must not be piled and fermented next to the chicken house. 4 to enhance ventilation, chicken house as much as possible to open some windows or roll up the surrounding plastic cloth, etc., the principle of ventilation is to ensure that the smell is not pungent smoked eye, and then ensure the temperature of the chicken house. To prevent stress When the number of flock is large, male and female should be kept separately. Due to the strong feeding ability of the roosters and the relative weakness of the hens, gregarious feeding is not conducive to fattening the hens. 1 Avoid the chickens being irritated by sudden high temperatures, strong light, sudden sounds, toxic gases, etc. Once you hear the frightened chickens and loud noises, immediately rush to the coop to comfort them. 2 When chickens are housed in chicken coops, care should be taken not to forcibly drive out of homes to avoid stress or lack of knowledge of the return. Instead, they should go out naturally and take the method of taking the material out of the house. Insect repellent management 1 Insect repellent, mainly refers to repelling locusts, aphids, nematodes, etc., usually with anthelmintic drugs to drive two insects in the breeding process, the first is 50-60 days of age, the second is 90-100 days age. Commonly used anthelmintic drugs are: a: levamisole, oral dose of 30 mg once per kilogram of body weight; b: albendazole, oral administration of 50 mg per kilogram of body weight; c: tetrazole, oral administration of 40 mg per kilogram of body weight. 2 Insect repelling mainly refers to repelling cockroaches, mosquitoes, cockroaches, cockroaches, etc. In the process of improving the environment and sanitation during the breeding process, we should always pay attention to whether the chicken's skin has bulges and red spots, especially the abdomen and legs. Commonly used drugs are: a: amitraz, according to instructions, when the spray effect is not ideal must be soaked. b: Trichlorfon, bathe with 01-50% of trichlorfon, taking care not to let the head enter the potion. c: Insecticide, 01% mix, used for 3-5 days. Disease prevention and treatment of disease prevention, adherence to prevention, prevention and treatment, strict disinfection, timely administration. (1) To strengthen the feeding and management of chickens and keep the chickens in a healthy condition is the primary condition for the reduction of disease. Each week use 100% poison and other disinfectants to disinfect the whole chicken spray. It is best to clean the floor and all utensils before disinfecting; do not allow unrelated personnel to enter the farm freely; when the temperature difference between day and night is too large, in the feed or drinking water Add some anti-typhoid, daytime, and chronic diseases drugs such as doxycycline, oxytetracycline, ciprofloxacin, norfloxacin, etc. In the hot summer season when heavy rain or high temperature is encountered, add multidimensional to feed or drinking water. With antibiotics and so on. 2 disinfection measures: The purpose is to eliminate pathogenic microorganisms in the contaminated environment, cut off the spread of disease, and control the occurrence and spread of chicken infectious diseases. Prophylactic disinfection, combined with the cleanliness of the house for 5-7 days; temporary disinfection, when the chickens are threatened by infection; disinfection with chickens to prevent the spread of pathogens through the surface of the chicken or feathers. Special circumstances and timely treatment, such as 22-35 days of attention to the occurrence of bursal disease, once the occurrence of drinking water with 5% glucose, and as soon as possible injection of double resistance; or found that the legs in front of one, the action of the chickens should be eliminated in time . Medication Notes 1 Strictly understand the indications, each drug has a unique chemical structure, have a certain scope of action, clear a variety of drug antibacterial spectrum, medication has targeted. 2 In the course of treatment or immunization with injection drugs, the chickens that have piled up together should be constantly driven to prevent chickens from being piled up and crushed to death. They should not be negligent. There are two methods for injections: one for subcutaneous injection and the other for intramuscular injection. Subcutaneous injection, usually in the middle or bottom of the back of the chicken neck, away from the head, with the thumb and forefinger to pinch the skin of the midline of the neck to lift it up to form a capsule, be careful to pinch the skin, and can not just pinch the feathers to ensure The needle is inserted under the skin to prevent the drug from being injected outside the body. Intramuscular injection, with wings on the chest muscles at the shoulders, should be carried forward obliquely to prevent accidents caused by insertion into the liver or chest cavity; it can also be injected in the legs, preferably with no blood vessels in the inner thighs of the chicken. 3 spices, drinking water medication. The dosage is accurate, the course of treatment should be sufficient, the dose is too small to reach the effective concentration, too large, the body is difficult to bear, leading to poisoning, while increasing costs. Treatment usually takes 3-5 days, should not stop the drug prematurely and lead to recurrence. Mixing medication: suitable for drugs that are insoluble in water; preferably in the morning, if medication is given in the afternoon, stop feeding for 2 hours before the medication; the amount of medicine should be guaranteed to be eaten by each chicken, and after the medicine is eaten, To stop for 2 hours and then feed the full price of the material; the drug should be mixed evenly. After weighing the drug for one day, first take 5 pounds of feed and the drug to mix well, then take 10 pounds of material and mix well, so many times, finally mix the need The amount of feeding. Drinking water medication a: stop the water for 3-4 hours first. If the hot season, the chicken age is relatively large, the water stoppage time may be shorter. To make the chicken have a certain thirst, if the chicken no longer drinks water, then achieve the purpose of treatment. Another injection or gavage; drinking buckets should be enough, to make more than 80% of the chicken can drink water at the same time, the preparation of drugs when the water quality should be clean, first use a large bucket of medicine and mix well, and then evenly distribute the bucket. Ensure that the potion is finished within 15-2 hours. Note that the potion should not be placed in the sun. b: The potable water should only be a water-soluble drug, an insoluble or slightly water-soluble drug, and a drug that is easily destroyed in water. , It is prohibited to invest in drinking water, so as not to affect the efficacy or poisoning, such as furazolidone, etc.; when drinking antibiotics in drinking water, it must be used immediately.
