Culture method of rock partridge
How to raise partridge 1? Partridges can be raised freely or in cages, which can make full use of indoor space. The reproductive density is about 0/0 females per square meter/kloc, which can make females who are unwilling to mate escape the pursuit of males, and the fertilization rate of eggs is also high. 2. The ratio of male to female is 1: 4-5, which can give full play to the reproductive ability of male and female, and also reduce the struggle between male and female, with high fertilization rate and low breakage rate. 3. The female thrush matures about 180 days, and the male thrush is one month earlier. The female thrush increased the light 3 weeks before opening, and the male thrush increased the light 2 weeks earlier than the female thrush. Light can be used to enhance the brightness, with an average of 3 watts per square meter and 2 meters from the ground. Ensure that there is 14 hours of light every day, and the enhancement requires uniform light and stable light. 4. The feed for laying owls should be comprehensive in nutrition, with metabolic energy1.15-1.17mj, crude protein content 18%, and trace elements and vitamins added. The feed formula can be evenly mixed with 53% corn flour, 12% wheat flour, 15% bean cake, 10% fish meal, 2. 1% shell powder, 0.4% salt and 0.5% multivitamin. Feed the partridges regularly every day to ensure that there is food all day, and the partridges can eat freely and have enough water at the same time. The laying room must be kept clean and the air fresh. Don't abuse drugs during laying eggs, so as not to affect laying eggs. Breeding of partridges: The artificially domesticated partridges have lost their nesting ability and must be artificially propagated. The hatching technology of partridge farm in Cao Xian Bay Town is introduced as follows: 1. Egg selection: try to use eggs within two weeks, and strictly select double yellow eggs and abnormal eggs. After selection, soak it in warm water at 30℃ and 0. 1% potassium permanganate for 3 minutes, take it out and dry it, then hatch. 2. Temperature: The key to success or failure of incubation lies in temperature. In the early incubation period, the machine temperature was kept at 37.8℃ 1 ~ 7 days, 37.5℃ for 8 ~ 20 days, and 37.2℃ for 21~ 24 days (i.e. incubation). 3. Humidity: Humidity should be adjusted according to various stages of embryonic development. The relative humidity should be kept at 60% ~ 65% in the early incubation period and 55% ~ 60% in the middle incubation period. In the later stage of incubation, in order to make the moisture in the air act on the eggshell together with carbon dioxide, sodium carbonate will be transformed into calcium carbonate, which will make the eggshell brittle, which is beneficial to the beak shell of young owl, and the humidity should be increased to 65%. 4. Egg turning: In order to heat the eggs evenly and make the embryos develop normally, eggs must be turned manually or naturally, usually every 2-3 hours from the second day of incubation, and can be stopped on the 20th day. Five, according to the egg: the first time according to the egg for 5 ~ 7 days, mainly to check the fertilization of the egg. Normal eggs can find eye spots on embryos, and the eggs are red and bloodshot. The yolk swells to one side. No sperm, no change, intact yolk and transparent egg white. Take out the sperm-free eggs in time. According to the number of eggs, the operation should be carried out according to the specific situation. Mainly check the embryonic development and take out the stillborn eggs in time.

Prevention of partridge disease: Pay attention to disinfection 1) Disinfectant ① bromogeramine solution: used for disinfection of eggs and utensils, and prepared into an aqueous solution of1:1000 ~ L: 2000 ~ L: 2000. ② Purple potion (gentian violet, nail violet): it is often used to treat wounds and ulcers. Prepare into 1% ~ 3% solution. Lysol (coal phenol soap solution): a solution with a concentration of 3% ~ 5%, which is often used to disinfect partridges, nets and excreta. If used for washing hands, the concentration is 2% ~ 3%. (4) Formalin (37% ~ 40% formaldehyde solution): used for fumigation and disinfection. ⑤ Sodium hydroxide (caustic soda): used for disinfection of partridges, excreta and environment, and generally prepared into 2% ~ 3% solution. ⑥ Quicklime (calcium oxide): used for disinfection of partridge houses, walls, ground excrement, etc. And its suspension 10% ~ 20% is commonly used, so it should be used carefully. ⑦ Bleaching powder: used for disinfection of partridge house and ground excrement. , generally prepared into 2% ~ 5% suspending agent, freshly prepared when used. ⑧ Potassium permanganate solution: commonly used for intestinal disinfection, appliance disinfection and wound washing of young partridges, generally prepared into 0. 1% ~ 0.5% solution.

(2) Disinfection ① Environmental disinfection: disinfect the environment around the partridge house with caustic soda solution or quicklime 1 time every 2-3 months; Disinfect the area around the site, sewage ponds, cesspits and sewage outlets with bleaching powder every 1 ~ 2 months 1 time.

② Disinfection of partridge house: The disinfection procedure is roughly as follows: cleaning, sweeping → washing → drying → first chemical disinfection → whitewashing walls and ceilings with 10% lime milk → moving into washed cages and other equipment for maintenance → second chemical disinfection → drying → formaldehyde fumigation disinfection. Clean, wash and disinfect carefully. Generally, the ceiling, back wall and floor are made first. From the side far away from the door to the side close to the door, the indoor environment should be gradual, and there are no dead corners and blanks. After cleaning, the feces and dust should be treated centrally, and the washed sewage and used disinfectant should be discharged into the sewer, instead of being piled up randomly near the partridge house or allowed to flow freely, causing new man-made environmental pollution around the partridge house. Alkaline disinfectants should be selected for the first disinfection, such as 1% ~ 2% caustic soda and 10% lime milk. For the second disinfection, chlorine preparation, surfactant, phenol disinfectant and oxidant with conventional concentration were selected and sprayed in turn with high-pressure sprayer. The third disinfection should be fumigated with formaldehyde, and the humidity of the partridge house should be above 70% and the temperature should be above 10℃. The disinfection dose is 42 ml formalin and 42 ml water per cubic meter volume, and then 2 1 g potassium permanganate is added. 1 ~ 2 days later, open the doors and windows and ventilate and dry the partridge house. The interval between each disinfection should be after the previous cleaning, disinfection and drying, and then the next disinfection.

③ Tableware disinfection: egg box, egg tray, incubator and incubator can use 0. 1% bromogeramine or 0. Firstly, 2% ~ 0.5% peracetic acid was used, and then 15 ~ 18℃ formaldehyde was fumigated in a closed room. The partridge cage is sprayed with disinfectant first, then washed with water, dried and sprayed with disinfectant, and finally fumigated with formaldehyde in a closed room. Workers' hands can use 0. 2% bromogeramine disinfectant, and prohibit the use of soap.

(4) Disinfection of drinking water: it refers to preparing diluent in another container in advance, and then putting it into a water dispenser or drinking tank for partridges to drink. This method can reduce the number of bacteria and viruses in water (some disinfectants can also kill parasitic eggs), thus reducing the occurrence of infectious diseases such as parasitic diseases. At present, the disinfectants approved by relevant departments mainly include chlorine (such as bleaching powder and sodium hypochlorite). ), iodine, bromine (such as bromine chloride, etc. ), cationic and zwitterionic surfactants (such as bromogeramine and chlorpyrifos). ).

⑤ Disinfection with partridge: It refers to spraying effective disinfectant on the environment and body surface of partridge house regularly during the whole feeding period of partridge, so as to kill or reduce pathogenic microorganisms and achieve the purpose of preventive disinfection. Disinfection of partridge should choose disinfectant with high efficiency, broad spectrum, non-toxicity, low corrosiveness and high adhesion.

The concentration of disinfectant commonly used for partridge disinfection is: bromogeramine (0. 1%), chlorpyrifos (1: 400), peracetic acid (0. 3%), sodium hypochlorite (0. 2% ~ 0.3%) and compound phenol.

Disinfection method of partridge: use a high-pressure sprayer, select 80 ~ 100 micron spray particles, and close the doors and windows according to the calculation of about 15 ml per cubic meter of space. Disinfect partridges for the first time should be no less than 10 days old, and then every 7 ~ 10 days old, 1 time. In case of epidemic, it can be used once a day 1 time. Disinfect partridges with 1 time after defecation.

Matters needing attention during disinfection: the partridge house should be cleaned frequently, and the feces, dirt and dust should be removed in time to avoid reducing the disinfection quality; When spraying disinfection, the nozzle should not be facing the partridge, and the concentration and dosage of the liquid medicine should be accurately grasped. The spraying degree should be based on the fact that the ground, wall and roof are evenly wet and the partridge body surface is slightly wet. The water temperature should be appropriate to prevent partridges from catching cold; After spraying, open the window for ventilation to make it dry as soon as possible; The temperature in the partridge house is 3 ~ 4℃ higher than usual; Various disinfectants are used alternately, with monthly rotation 1 time; Spray disinfection should be stopped within 3 days before and after partridges are inoculated with attenuated vaccine.
