Thanks to the efforts of researchers, after more than ten years of artificial hatching experiment of meat pigeons, our field successfully completed the artificial hatching and artificial breeding of meat pigeon breeding, and broke through the low survival rate of artificial pigeon milk synthesis in practical applications. The technical difficulties solved the series of problems that traditional breeding meat pigeons have low fertility, short service life, high production cost of pigeons, and weak market competitiveness of commercial pigeons. This technology will be the same as the hatching of chickens, hatching ducks, the degree of simplification, its scale is very large and small, very suitable for promotion in China's rural meat pigeon breeding households. Its technical methods mainly include the following aspects:
1. Incubation equipment First of all, infrastructure such as incubators, hatchers, and young pigeon incubators should be prepared. The countryside can be self-made, its cost is low, the operation is simple, and the effect is basically similar to that of a large-scale hatchery.
2. After the eggs are fed each morning, the eggs produced in the egg nest are gently removed and put into a plastic box to avoid scratching the shell. At the same time, record the files of breeder egg production in order to establish a high-yielding, excellent breeder population. The collected pigeon eggs are placed in hatchery-specific egg trays, and sand shell eggs, misshapen eggs, and eggs that are too large and too small to hatch are selected. The disinfectant is sprayed and disinfected in proportion. After the water is allowed to dry, it can be pushed into the hatcher for incubation.
3. The hatching time is determined by the number of pigeon eggs. When the quantity is large, it can be put in once a day. When the quantity is small, the egg can be stored in the incubator for a few days. Before the egg can be sent to the incubator, the incubator must be warmed for a period of time. Only when the desired temperature set point has been reached can the breeding pigeon eggs be hatched and marked with the date of insertion. The standard temperature for pigeon egg hatching is set at about 38.1°C, the humidity is set at 55%, and it is controlled between 50% and 60%. During hatching, the automatic turning of the egg is carried out for 2 hours. The turning of the egg can be done manually for 3 to 4 hours. When the hatching reaches the 5th day, eggs can be picked as usual. When hatching to the 10th day, take an egg again and pick out dead dead eggs and stillbirth eggs so as to prevent the broken eggs from breaking and contaminating the box and affecting the hatching effect of the whole box.
4. Breeding. Pre-heat the hatching machine to the set value. The hatching temperature standard is 37.8°C and the relative humidity is 65%. Remove the pigeon eggs that have been hatched for 1.6 days from the incubator and gently place them in the dropping rack. After taking them, they are sent to the hatching machine. After 1 to 2 days, the hatchlings break shells and emerge. Individual shelling difficulties can be artificially assisted in shelling and timely removal of hatched egg shells. When the fluff on the young pigeons is dry, they can be transferred to the young pigeon incubator, and it is advisable to turn the young pigeons three times a day.
5. Brooding Set the incubator at 35°C. The humidity requirement is not high. Place a water tray inside the box. When the temperature rises to the set value, the hatched young pigeons can be transferred into the box. The amount of feed should be based on the number of young pigeons. The current use of fresh pigeons can maintain the freshness of the feed to avoid wastage. The synthetic pigeon milk was mixed with water in a ratio of 1:3 and was thoroughly mixed until ready for use. 0 to 3 days old young pigeons can be fed with a 50 ml syringe, and the amount of feed should be 80% full and fed 3 times a day. The specific method of operation: the middle finger of the left hand and the thumb fixed the squat of the pigeon, the index finger on the upper jaw, the right hand with a syringe to feed. Four- to seven-day-old pigeons can be fed with a 100-ml syringe to speed up the feeding of chicks at 08 to 15 days of age. The temperature can be set at 31-28 °C. When the temperature is low, the young pigeons will play with each other in a crowded manner, and at the same time they will give a call for "squeaking." When the temperature is high, the young pigeons will open their mouths to breathe. In severe cases, the young pigeons will have wet feathers. The breeder observes the above phenomenon and should adjust the temperature setting in time. 8 to 10 days old young pigeon feed can be prepared according to the transition period, that is, 50% of artificial pigeon milk plus 50% of chicken feed. Pigs over 15 days old do not need to incubate and can be transferred to a normal temperature fattening rack and fed twice a day. After 28 days of feeding, the pigeons weighing more than 0.6 kilograms were sold on the market.
6. Strengthen day-to-day management As the young pigeons are artificially fed throughout the entire process, the requirements for usual hygiene management are also strict, and the quality of the drinking water and the freshness of the feed must always be maintained. The young pigeons before the age of 15 days should clean up the pigeon droppings once a day. The feeding and finishing tools should be cleaned in time. The lofts should be regularly sterilized and carefully managed to ensure the normal growth of the pigeons.
