Natural Incubation Technology of Meat Pigeon

After the pigeons are paired, they then breed, and the female pigeons crouch in the nest basin for a long time. When the second egg is laid, the parent pigeon begins to hatch. In the process of holding the eggs of the parent pigeon, the following management work should be paid attention to and carried out: (1) keep the environment quiet, avoid external interference and stress factors, and give the pigeon cage proper shading if necessary to urge the parent pigeon to concentrate on hatching. (2) the nest cushion had better be double-layer old linen cloth, the grain husk or sawdust or dry fine sand under the linen cloth, the dry fine sand is more ideal, and the thickness in the nest basin is 2-3 cm. The breeder should check the situation of laying and hatching eggs every day, and pick it up in time once the damage is found. (3) improve the feed nutrition level during the egg holding period, ensure that the crude protein content reaches 18-20%, and the energy level is also increased accordingly. So that the parent pigeon has a strong physique, laying a good foundation for feeding squab. It is necessary to prevent the eggshell station from polluting the feces, as germs may invade the eggs and cause the embryo to die. If the feces have been stained, they can be cleaned with gauze. (4) it is a necessary work to look after the eggs. The eggs were illuminated once on the 5th day and 10th day of incubation. When the egg is illuminated for the first time, it is found that there are reddish-brown, spider-web-like blood vessels in the egg, and the shape is stable, that is, the fertilized egg, let it continue to hatch, if there is a blood vessel distribution in the egg, but a thick line, showing a "U" shape, then it is a dead sperm egg; if transparent and without blood vessels, there are no sperm eggs, dead sperm eggs and non-sperm eggs should be picked up. The egg was illuminated for the second time on the 10th day of hatching. if most of the area of the egg was black and a bright blank area was formed at the other end due to the enlargement of the air chamber, it indicated that the embryo was developing healthily. If there is no clear distinction between black and white in the egg, the material in the egg is unstable, there is a sense of wave movement when turning the egg, and the eggshell is gray, that is, it is a dead embryo egg. (5) do a good job of merging eggs in time, because merging eggs is one of the effective measures to improve the fecundity of meat pigeons. After taking out the non-sperm eggs, dead sperm eggs and dead embryo eggs, merge them into a litter according to each litter, and put the remaining eggs into other nests with the same incubation period or a difference of 1 day. It would be better to nest after 10 days. If the pigeons were nestled together 10 days ago, the pigeons in the empty nests could lay eggs in about 8 days. Early laying would affect the recovery of pigeons' physical strength. The next litter may not have strong vitality, or there may be no sperm eggs, dead sperm eggs, dead embryo eggs, and so on. (6) it is important to know the date of coming out of the shell. When shining for the second time 7-8 days after the egg, pay attention to observe the shell situation of the squab. If it is really difficult to get out of the shell, manual help is needed. Generally hatching has reached 18 days, the shell surface only pecked through a small hole, the need for manual assistance shelling. The incubation period has been more than 18 days, and the embryo may have died without pecking at the shell. The appearance of squab shell is shown in figure 5-4. (7) the hatching temperature of pigeons is very important and should be kept at a suitable temperature. In winter, the temperature in the room should be kept above 5 ℃ at least. If the temperature is too low, it should be heated in the room, otherwise it is easy to freeze to death in the early stage of hatching. In the hot summer, it is necessary to reduce the bedding properly, open the doors and windows, turn on the exhaust fan, and keep the room temperature below 32 ℃, otherwise it is easy to cause stillbirth in the later stage of incubation.
