The meat-raising pigeons are generally selected from pure-breeding king pigeons and silver-king pigeons. They can be fed with three-layer single-cage indoor production. The eggs produced by the breeders are placed in small batches incubators for hatching. Due to the small size of the eggs, the egg frame should be changed to an egg rack suitable for placing pigeon eggs.

The pigeon eggs have a thin shell with sensitive temperature, sensitive shell, smooth shell structure, poor air permeability, slow evaporation, and resemblance to duck eggs. However, as much as 74% of the protein in the inner pigeon's egg and the gum is transparent, this determines the poor thermal conductivity in the early stage of the pigeon's egg. The incubation temperature is controlled at 37.8-38.3°C. The suitable humidity for artificial hatching pigeons is about 10% lower than that of hatching chickens, and the relative humidity is 55%-65%. The humidity should not be too high. However, it should also be avoided that due to the space in the cabinet, the fan is too large and the humidity is too dry to affect the hatching. According to the egg divided into three times, the first time in the first 5 days after hatching, remove the zygotes and dead zygotes; the second on the 10th day, the third on the 16th day, remove the embryonic eggs and transfer them out In the hatchery, pigeons began to hatch on the 17th and 18th days.
Improve measures
1, broken egg repair: the undissolved broken pigeon eggs with latex, egg white, tape (medical volume type), with the seal method or patching after hatching. This single can increase the production of young pigeons by 3%.
2.Statistics of azoospermia: Embedding anaerobic dead embryos as a detailed record and documenting and adjusting the pigeons at any time. This plays an important role in improving the hatching rate of fertilization.
3, outside the box to dry the eggs: the eggs have hatched older than 12 days old embryos, out of the egg cell in the incubator outside the eggs, the new hatching eggs in the original box as usual hatch. This method can solve the problems in constant temperature incubation and can greatly increase the hatching rate and the rate of hatching.
Artificial feeding
After the hatchlings get out of their shells, the better way is to use the method of looking for nanny pigeons to feed, that is, when the young pigeons hatch out, they are nurtured by the nanny. General nanny pigeons are medium-sized and have no disease and are in good spirits. They are nurturing pigeons with 1-2 days of age or 17-18 days of hatched pigeons. Pairs of pigeons can feed 2-3 pigeons. Feed artificial synthetic pigeon milk once a day.
Artificial brooding method: use a 20 ml syringe within 3 days, remove the needle, and insert it with a small hole soft hose. Each time the amount of feed can not be too much, feeding 4 times a day; 4-6 days of age feeding with a small bucket type feeding device, fed 4 times a day; 7 days after the pigeons out of the relatives, completely artificial feeding, Put the pigeons in a brooding cage.
