Artificial hatching and feeding techniques of farmed meat pigeons

Breeding meat pigeons generally choose purebred king pigeons and silver king pigeons, raising methods can be used indoor three-story single cage matching production. The eggs laid by breeding pigeons are put into small incubators to hatch in batches. Because pigeon eggs are small, the egg rack of eggs should be changed into an egg rack suitable for pigeon eggs.

Apply temperature and control humidity

Pigeon egg has the advantages of thin, warm and sensitive shell, smooth shell, tough and fine shell structure, poor air permeability, slow evaporation of water, similar to Muscovy eggs. However, the protein from the internal pigeon egg is up to 74%, and the colloid is transparent, which determines the poor thermal conductivity of pigeon egg in the early stage. The incubation temperature is controlled at 37.8 ℃. The suitable humidity of artificially hatched pigeons is about 10% lower than that of hatched chickens, and the relative humidity is 55% 65%. It should be noted that the humidity should not be too high. But should also avoid because the box space, the fan is too big, the humidity is too dry to affect the hatching. The eggs were taken out in three times, the first time on the 5th day after hatching, the second time on the 10th day, and the third time on the 16th day, the dead embryo eggs were taken out of the machine, and the pigeons began to shell on the 17th and 18th days.

Improvement measures

1. Repair of broken eggs: hatch the broken pigeon eggs with latex, egg white, adhesive tape (medical roll type), sealing method or patch. This alone can increase the yield of young pigeons by about 3%.

2. Statistics of azoospermic dead embryos: record and file the azoospermic dead embryo eggs, and deal with and adjust the pigeon flocks at any time, which plays a very important role in improving the hatching rate of fertilization.

3. Drying eggs outside the box: the old embryos of pigeon eggs that have been hatched more than 12 days old are drawn out to air the eggs outside the incubator, and the new eggs in the original box are hatched as usual. This method can solve the difficult problem in constant temperature hatching, and can greatly improve the hatching rate and healthy rate.

Artificial feeding

After the pigeon comes out of its shell, a better way is to find a babysitter to feed the pigeon, that is, as soon as the pigeon comes out of its shell, it will be fed by the nanny pigeon. General nanny pigeons choose medium size, no disease, good mental state, are feeding 1-2-day-old pigeons or parent pigeons who have hatched eggs for 18 days. A pair of parent pigeons can be fed with 3 pigeons. At the same time, they are fed with synthetic pigeon milk once a day.

The method of artificial brooding: use a 20 ml syringe within 3 days of age, remove the needle, and put it in with a small hole flexible hose. Do not feed too much each time, 4 times a day; 4-6 days old, with a small bucket feeder, 4 times a day; after 7 days of age, the squab is separated from the parent pigeon, and the squab is completely artificially fed, and the squab is placed in the nursery cage.
