First, preservation and purification of rejuvenation technology The American White Feather King pigeon is the preferred breed of meat pigeons. They have the advantages of strong fertility, fast growth, large size, high feed rewards, strong disease resistance, and good genetic performance. However, if you do not pay attention to doing a good job of seed conservation, there is no strict purification and rejuvenation measures. After a few years of raising, the core population of varieties will soon degenerate due to the inquiries. Therefore, it is necessary to proceed with the preservation and purification of rejuvenation work. The measures include the following aspects: 1. Appearance requirements Selection of healthy warm body, well-proportioned structure, strong feeding habits, deep chest width and protruding forward, back flat wide and long, keel straight without bending, plumage, pure white smooth lubrication and young birds close to the body stay Reserve pigeons. 2. Body type selection requires a longer body length, but the tail is not in the ground, the chest is wide and deep, and the reserve pigeons of moderate size are reserved for species use. 3. Production performance requirements The pigeons have a high rate of egg production, a high fertility rate, a low dead embryo rate, good incubating ability, and a strong brooding ability. Progeny breeds up to 3 pairs of eggs each month. The descendants of high-yielding pro-pigeon breeds whose litter cycle is less than 35 days per litter are reserved for breeding. 4. The growth rate requires the selected species of pigeons to use 30-day-old weight, more than 550 grams of hens, and more than 600 grams of cocks, to be reserved for seed use. 5. The group selects and matches the whole group core group AB. The cocks of the offspring of Group A are paired with the hens of the offspring of Group B, and the cocks of offspring of Group B are paired with the hens of the offspring of Group A to prevent inbreeding. 6. Make a record The above activities must be well documented, established cages, formed archives and pedigrees, and often tested. Conditional pedigree identification, pedigree analysis, understanding the pros and cons of descendants, timely detection and adjustment of problems. Elimination of poorly recorded cages. Second, "fight three hatch eggs" technology In the medium and small fields (households) under the conditions of artificial hatching and artificial feeding techniques, the first application of “trimming three eggs†explores production experience, improves pigeon production, increases efficiency, and has quick effects. specific methods: 1. Breeding group 30% of the young breeders with good egg production performance and high fertilization rate were selected, but young hatchling breeders with poor hatchability and poor feeding performance were used as a specialized pigeon production group. 70% of the well-aged, well-fed, old-age breeders were used as hatchery groups to perform hatching tasks. The two groups of breeders do not need to move the cage position, as long as they can be distinguished by recording in their home position. 2. Egg hatching The pigeon eggs laid by the breeding group of pigeons were taken out at 8 o'clock on the same day and they were given to the hatchery group. Three eggs were hatched in each nest. The spelled 1/3 laying group breeders are exempted from the hatching task and produce full-time eggs. A nest egg (2 pieces) will be produced about every 7 to 13 days, which will greatly increase the egg production rate of the whole breeder. 3. Do a good nesting At the bottom of the nest, put a layer of burlap, topped with straw (cut into 3 to 4 cm), chaff, and other padding to make the bottom of the pot. Put a layer of burlap on top. The purpose of nesting is to make the 3 eggs can not be rolled and frozen, so as to reduce the damage of pigeon eggs and improve hatching hatching rate. 4. Adjust eggs The eggs are taken every 4 to 5 days, and they are taken out every time when there are no eggs or dead embryos, and the eggs are adjusted according to 3 eggs for each nest so that the pigeons being put together can produce eggs early. This action has a significant effect on increasing egg production. 5. Breeding adjustment After 17 to 18 days of hatching, the young pigeons hatched and were adjusted flexibly according to the number of hatches per day, so that 3 of them were fed with strong feeding ability and 2 of them were fed with poor feeding ability. For breeding pigeons with three birds, supplemental water should be added. In order to shorten the laying cycle by reducing the weight of the breeding pigeons, they can be fed artificially to the market when they are fed to 7-8 days of age, which can increase the egg production. 6. Nesting It is the nature of the pigeons that the breeder is nested and hatched after laying two eggs. When artificial pigeons are taken away for a long period of time, a few species of pigeons will have a love nest nest to delay the next round of laying time. The effective and simple method is: When the egg is taken, the litter is dropped off (should be the active egg nest), and the hatching pigeons are forced to wake up immediately without nests, and the eggs are returned to the egg nest every 6 days to produce a second round of eggs. It not only solves the problems of laying eggs, but also facilitates cleaning and disinfecting the egg nests, and prevents eggs from being covered with feces. Third, the artificial hatching pigeon technology The use of artificial hatching pigeons instead of natural hatching pigeons eliminates hatching tasks, shortens the laying cycle and increases egg production. The second is to avoid adverse effects such as broken eggs and cold embryos when hatching pigeons. Factors, thereby increasing hatching rate and hatching rate. Correctly mastering the technology of artificial hatching pigeons can increase the hatching rate from 68% of the natural pigeons' natural hatching to 88% of the artificial hatching pigeons. Artificial hatching pigeons and artificial hatching chickens are slightly different in their specific operations. 1. Take eggs After 8:00 every evening, all pigeon eggs produced by all breeders should be taken out. It should not be too early or too late. Some breeders do not produce eggs prematurely; when they are late, some breeders have the habit of incubating immediately after laying eggs, causing the temperature of pigeon eggs to rise and adversely affecting artificial hatching. When taking eggs, the egg nests must be removed together to avoid affecting the next round of laying eggs. When you take the eggs, you need to make a record of the pigeon's egg production time and pigeon eggs, and create a file. After removing the pigeon eggs, they can be directly hatched into the hatchery or temporarily stored. The storage temperature must not be higher than 20°C, nor lower than 5°C, and the air must be freshly circulated. If necessary, eggs can be kept in an incubator or egg store kept at a constant temperature of 18°C. 2. Incubation Using a small hatchery, the hatched egg trays were changed to egg trays for hatching pigeon eggs. For the convenience of management, after 4 days of continuous egg retrieval, all eggs can be placed into the incubator at one time for incubation, and then every 4 days thereafter for an incubation cycle. The incubation temperature is controlled at 38.3 to 38.8°C throughout the incubation period, which is 0.5 to 1.0°C higher than the egg hatching. Relative humidity is 50% to 55%. Turn eggs 4 to 6 times a day. When the pigeon eggs hatch to the 12th day, remove the eggs once a day and cool the eggs outside the hatchery to reduce the temperature to 30°C and return them to the hatchery. The newly hatched pigeon eggs are hatched as usual in the original machine. 3. Eggs Five days after each batch of pigeon eggs were hatched, the first egg was placed and the lean and early embryonic eggs were promptly removed. The eggs were hatched for the second time when the eggs were hatched to 10 days, and the eggs were hatched for the third time after hatching until the 16th day. The eggs were taken out in time to prevent the eggs from affecting the hatching effect. The hatchlings begin hatching in 17 to 18 days. Through long-term production practice, it has been proved that the hatching rate of artificial hatching pigeons is high, the appearance of young pigeons is beautiful, the ratio of breeders to breeders is high, there is no big belly belly, and the eggshells after hatching are clean and satisfactory results are obtained. Fourth, feed matching technology The old-fashioned pigeon diets are fed with simple raw materials and are now lagging behind. In order to ensure different nutrient requirements for meat pigeons in various growth and production stages, according to the type, quantity, and quality of nutrient substances in the raw dietary grains, the diets are automatically calculated in proportion and processed or made into granules to meet the nutritional needs of the pigeons. To achieve high efficiency and low cost. The application of compound feed technology has greatly changed the face of the pigeon-raising industry, improved the pigeon's nutrition and improved productivity. Now introduce part of the feed formula for reference. 1. Pigeon feed formula 1 to 4 days old milk powder 50%, egg white 35%, vegetable oil 5%, speed supplement-14 5%, bone meal 2%, yeast powder 1%, protein digestive enzyme 1%, dried fish oil 1%, plus salt 0.1% . 5 to 7 days old milk powder 40%, 25% chick material, 20% egg white, vegetable oil 5%, rapid supplement-15%, bone meal 2%, yeast powder 1%, protein digestive enzyme 1%, dried fish oil 1%, another Add salt 0.1%. 8 to 10 days old milk powder 15%, chicken material 50%, egg yolk 20%, vegetable oil 5%, speed supplement 14%, bone meal 3%, yeast powder 1%, protein digestive enzyme 1%, dried fish oil 1%, another Add salt 0.1%. 11-15 days old powdered milk 10%, chicken material 65%, egg yolk 10%, vegetable oil 5%, speed supplement-13%, bone meal 4%, yeast powder 1%, protein digestive enzyme 1%, dried fish oil 1%, another Add salt 0.2%. 16 to 24 days old powdered milk 5%, chick material 80%, vegetable oil 5%, rapid filling - 14 3%, bone meal 4%, yeast powder 1%, protein digestive enzyme 1%, dried fish oil 1%, plus salt 0.2 %. 25 to 30 days old powdered milk 5%, chicks feed 85%, fast filling - 14 3%, bone meal 4%, yeast powder 1%, protein digestive enzyme 1%, dried fish oil 1%, plus salt 0.2%. 2. Young pigeon feed formula Corn 55%, pea 20%, mung bean 5%, wheat 15%, hemp kernel 5%. 3. Production Pigeon Formula 45% of corn, 27% of peas, 5% of mung beans, 15% of wheat, and 8% of hemp seed. The production pigeons should be divided into new mating pigeons, non-lactating pigeons (including hatching period, moulting period and production pigeons without production tasks), pigeons during lactation, etc. according to different production stages. 4. Non-production pigeon universal feed formula 30% to 70% of corn, 10% to 15% of sorghum, 10% to 30% of rice or brown rice, 10% to 20% of wheat, and 3% to 5% of hemp seed. Flexible selection by season, origin and price. In order to maintain the relative stability of the production pigeons for egg production, hatching, and nurturing, the free movement of the feed is minimized, including the formula ratio, timing, and ration. Keepers must be able to accurately weigh and mix ingredients, and feeds must be added. If there is a shortage of raw materials for feed, it must be changed slowly to avoid sudden changes in production. Fifth, artificial nursing pigeon technology The artificial feeding of pigeons is a scientific, highly hygienic and demanding operation. To do a good job in this work will play a decisive role in improving the quality of the pigeon's meat, increasing the pigeon's yield, and improving the efficiency of pigeon production. Specifically, we must do the following tasks: 1. Tools (1) Feeding pigeons: use Medical Equipment supplies, suction ball or syringe (remove needles) to change into small-capacity feeding pigeons; design larger-capacity barrel-type feeding pigeons, including bucket-type feeding pigeons, pedal-type feeding pigeons Machine and pistol-type electric air-controlled feeding pigeon machine. (2) Brooding Incubator: It is used for the insulation of 1-7-day-old pigeons. (3) Brooding pigeon cages: Generally, rectangular galvanized mesh plane pigeon cages with a length of 200 cm, a width of 100 cm, a height of 50 cm and a mesh of 1 cm and 1 cm can be produced for artificial brooding of 8 to 16 days old pigeons. 17 to 26 days old pigeon cage cage design, 4 to 6 for a cage. The capacity and number of pigeons, incubators, and pigeon cages should be determined according to the scale of production. 2. Brooding After 17 to 18 days, hatchlings hatch out of the shell and enter the brooding room and are placed in an incubator or incubator. At the age of 1 to 4 days, the temperature is 37 to 38°C, the temperature is 5 to 7 days when the temperature is 34 to 36°C, and the feeding is done by sucking the ball feeder or the injecting feeding pigeon; 8 to 15 days old plane transfer Brood cages, temperature requirements 30 ~ 33 °C, then gradually reduced to room temperature. At this time, a larger-capacity barrel feeder was used for feeding; cages of 16 to 26 days of age were slaughtered in basket-type cages. During the entire brooding process, attention should be paid to insulation and ventilation. 3. Preparation of pigeons Whether or not artificial breeding techniques for pigeons can succeed, the most critical thing is the preparation of pigeons. Mix according to the above formula, mix well, warm the amount of boiled water, cool to 40°C, 1～4, 5～7 days old puddle material is liquid, 8～10, 11～15 days puddle material is pastey 16 to 24 days old puddles are dry and wet; 25 to 30 days old puddles are dry and wet, and are self-eating. 4. Step by step When artificial feeding technology is applied, it is necessary to comprehensively spread the experience on the basis of a small amount of experiments. It is possible to carry out artificial feeding for a week after the breeding of the breeding birds, and gradually realize the artificial feeding of the entire period after the basic grasp. 5. Take the "five levels" The artificial nursing of the pigeons should be based on good health clearance, temperature off, pigeon feeding preparation, feeding technology, and “admission from the mouthâ€. Among them, the puddle material preparation is the key to success, sanitation and disinfection, to prevent "sick from the mouth into" is an important part of the success, these five aspects are grasped well, in order to ensure the health and normal development of the pigeon. The artificial incubation of pigeon eggs combined with the artificial breeding of pigeons eliminates the two tasks of breeder hatching and feeding, shortens the laying cycle of breeders, increases egg production and pigeon production. According to the practice in our city, the egg production cycle of the breeding pigeons was shortened from 35 to 40 days to 10 to 15 days, which greatly increased the economic efficiency of the pigeon farms.
