Several measures to improve the survival rate of three yellow chicken chicks

Beiliu City is home to Guangxi Sanhuang Chicken and is one of Guangxi's largest three yellow chicken production bases. Three yellow chickens have yellow, yellow and yellow skin, thin skin, fine meat, and a strong reputation for meat. In recent years, the market consumption has grown rapidly. Sanhuang chicken breeding has shown a very broad prospect for development. However, some specialized households do not deal with the technical measures in detail in the broiler breeding of Sanhuang Chicken, which affects the development of the entire chicken growth stage, resulting in a decrease in the overall survival rate and impaired breeding efficiency. Successful practice by many farmers in the city has proven that brooding is the key to the success of breeding yellow chickens, and the higher survival rate and higher uniformity in the brooding period are key factors in the success of the overall breeding. The quality of brooding not only directly affects the survival rate of the chicks, but also affects the whole broiler growth process. Therefore, raising good yellow chickens must start from brooding. Grasping scientific brooding techniques is the key to improving the survival rate of three yellow chicken chicks. In the process of three yellow chicken brooding, we must pay attention to five key issues. Good transport of young chicks The transport of young chicks is an important part of the brooding process and it is one of the key technical measures for successful brooding. After selecting the primary young hair stems, they can be transported. The transportation can be selected according to the distance. It is best to use thermal cages, boxes or insulated cars to transport chicks during the cold season in winter and spring. The transport time should be as short as possible. , It is best to reach the destination within 48 hours, a long time will have a greater impact on the growth and development of chicks. Young children should not be packed tightly to prevent chicks from crushing to death. In addition to transporting cold weather, we must also prevent heat, sun, rain, and bumps. The temperature of the cage (box, car) is preferably 28°C-30°C. Travel far and poor conditions should also pay attention to observe the dynamics of chicks at any time to prevent accidents. Grasp the appropriate temperature, humidity, density and light to grasp the appropriate temperature is the key to ensure the health of the chicks, hatched chicks are small and delicate, less feathers, weak disease resistance, nervous system and physiological function is not sound enough, egg yolk Absorption is slow, inactive, and poor in adaptability to outside temperatures. Proper temperatures help chicks withstand the cold and promote the absorption of egg yolks as quickly as possible. Low temperature directly affects the growth and development of chicks, easy to get diseases, high appetite or even normal metabolism. It is generally required that the first week of the brooding house temperature is 35°C-32°C, and the second weekly week is 2°C lower, until it is reduced to 27°C, and the night temperature should be 1°C-2°C higher than the daytime. Observing the condition of the flock can know whether the temperature environment is appropriate. If the chickens get together into groups, then the temperature is too low, they should be warmed; the chicken's mouth should be overheated and should be cooled; the chickens should be evenly dispersed and the head and neck should be straightened. While sleeping, it is normal temperature. The length of the insulation period should also vary from season to season. In summer and autumn, the temperature is high, the holding time can be shortened, and the temperature can be defrosted at the age of 3 weeks. In the winter and spring cold season, the holding time can be longer and the temperature can be defrosted after 6 weeks of age. Maintaining the proper humidity Humidity of the brood can not be ignored. Generally, the relative humidity for brooding of 1-10 days is 60%-70%, and above 50%-60% for 11 days; if the humidity is too high, the indoor is too humid, it is easy to cause Indigestion, dysentery, E. coli disease, coccidia, bursal disease, etc. Note that if the density is too high, it will cause poor ventilation, indoor ammonia, hydrogen sulfide, and carbon dioxide concentrations too high, which can easily lead to multiple diseases and increase mortality. If the density is too small, the effective area cannot be fully utilized to cause waste. It is generally 30-40 per square meter from 0-3 weeks old, and 20-30 days from 4-6 weeks old. It is very beneficial to increase the survival rate of the chicks by mastering the light illumination so that the vitamin D source in the chick's body can be converted into vitamin D, participate in metabolism and promote development. In the first 2 weeks of the bred, day and night light is used. Day and night light can increase the brightness in the brooding house, stimulate the vitality of the chicks, and increase the food intake. However, in order to prevent premature sexual maturity, 2 weeks of age should be properly controlled after the light time, according to the temperature conditions during the day to reduce the light time, to 9 hours a day can be light. Note that early feeding of water to chicks is a major part of the organism and is an indispensable and important substance in metabolic processes. After the chicks enter the house, they should supply drinking water as soon as possible. It is best to drink fresh water within 24 hours after the chicks hatch. In particular, after long-distance transportation of chicks, the nutrients stored by the chicks themselves are no longer able to maintain their normal metabolic needs. They are consumed by the consumption of nutrients in the body. If the water is not refilled early, it can cause the feet of the chicks to become dry, and the spirits are weak and the feathers are loose. Blocked or even died. After long-distance transportation or winter chicks, the first day to feed 5% glucose water, or "eat salt," water, can quickly and effectively add fluid consumption, improve anti-stress and disease resistance. In the cold season, it is necessary to put drinking water into the brooding room in advance to preheat or drink warm water, and the temperature requirement is basically the same as the temperature in the house. To select fresh, high-quality, full-price chicks, timely feeding of full-price nutrition is the material basis for the rapid growth of the chicks. The chicks must obtain enough nutrients from the feed to maintain normal growth and development. The metabolic energy of the nutrients contained in the chick's feed is 2.9. - 3.0 Mcal/kg, crude protein 20%, calcium 1%, phosphorus 0.75%, salt 0.32%. It is more appropriate for the chicks to start feeding 24 hours after hatching. Chicks need to drink for half an hour before they can feed and eat. If the transportation time is long, they need to feed before the water for 1-2 hours. Chick gastrointestinal volume is small, poor digestion, but rapid growth and development, metabolism is strong, so to increase the number of meals, less place Tim Tim, usually 2 weeks feeding 8 times / day, 2 weeks after 6 times / day. Doing a good job of epidemic prevention and control work Chicks are weak in disease resistance and are vulnerable to disease. Especially for dermatophytosis and bursal disease, they are the most common diseases. Therefore, we must do a good job of prevention and treatment of common diseases in chicks so that they can use vaccines properly and sanitize the environment. This is a key part of improving the survival rate of broodstock. At the chick stage, the most serious threats to brooding are: chicken fleas, typhoid fever, colibacillosis, coccidiosis, Newcastle disease, infectious bursal disease and respiratory diseases. The main prevention and control measures are as follows: Various brooders and feeding troughs can be cleaned and disinfected with 1:500 poisonous dilution liquid, and often spray the chicken house and ground with the disinfectant fog, and pay attention to replacing the ventilation and ventilation of the bedding and the young house. Two to three days before the first week, enrofloxacin and chlorhexidine quinolones were mixed into potable water in proportion to effectively prevent P. berghei, chicken chronic respiratory diseases, and E. coli. Water-soluble gentamycin is fed for 4-6 days, such as “Bacteria Bijing” produced by North China Pharmaceutical Factory, 1 kg of water is used per kilogram of water, and ampicillin is available for drinking water for 7-10 days, every 40 g. Medicine mixed water 40-100 kg. 11 days later, 0.125% of the compound enemy bacteria were fed. After 15 days, anticoccidial drugs such as Acetaminophen, anti-ball king, etc. can be used for prophylactic use, and the amount of anticoccidial drugs should be appropriately increased if the disease occurs. The immunization procedures for Sanhuang chicks are: Inoculation of Marek's vaccine (liquid nitrogen seedlings) within 24 hours; Newcastle disease II virus vaccine + Bursa vaccine at 7 days of age; Newcastle disease II vaccine after 13-15 days. Weak vaccine + bursal vaccine; 25 to 26 days of vaccination against infectious laryngotracheitis; 35 to 40 days of vaccination against Newcastle disease I.
