The artificial hatching pigeons also took place shortly afterwards. With the rapid development of the large-scale breeding pigeon industry in China, the application of artificial pigeon feeding technology has increased, and the number of artificial hatching pigeons has also increased. This is a new technology for the modern pigeon industry to increase production and increase income. Someone said: "The artificial hatching pigeon is the same as the hatching chicken." In fact, this is not the case. Due to the differences in the biological characteristics of pigeons and chickens, their respective embryonic development is also not the same. How to explore the correct temperature according to their developmental characteristics and strive for the best hatching effect is indeed a concern for the modern pigeon industry. Now we will discuss the practical key technologies of artificial hatching pigeons, and discuss the practical techniques of 20 years of experience in hatching birds and cumulative breeding of more than 100,000 pigeon eggs for 6 consecutive years. We will now introduce relevant research results to industry colleagues. .
First, Schwing on the basis of pigeon eggs, a small shell sensitive to temperature sensitive, smooth shell, tough shell structure, poor permeability, slow evaporation of water, exactly like 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. In order to verify the scientific data of the optimum temperature and humidity of the artificially hatched pigeons, a number of species of poultry eggs and pigeon eggs were used in the same box at the same temperature and humidity for multiple incubation tests. It was found that the temperature of the artificially hatched pigeons was higher than that of hatched chickens. In order to verify the accuracy and effectiveness of the best temperature data for artificial hatching pigeons, a series of experiments with different levels of temperature, humidity, and humidity were conducted over a period of 6 years. Incubation batches) The more representative hatchery records are reported below (see table below):
It was found in experiments that when the long-term low 37.8°C hatching pigeons were used, although the low temperature did not cause abnormal embryonic development and death, the embryos developed slowly, the protein absorption was poor, the shelling time was long (more than 19 days), and the young pigeons were large. The navel is unusually long, the eggshell is dirty, and the rate of hatchlings is low. Try the pigeons from 39°C to 39.2°C. Because the temperature exceeds the upper limit and the long-term temperature is too high, the embryos are not able to withstand high temperatures. Not only does the embryonic embryo rate in the whole period high, but there are blood pods, umbilicus, young pigeons, and gumballs. In the remaining protein shells, the hatching rate was significantly lower and the experimental results failed.
Second, the best Schwing According to the experimental data, to determine the entire period of incubation in the constant temperature range of the best temperature, according to the regional climate hot days, respectively, flexible temperature 38.3 °C to 38.8 °C between. This temperature should be calibrated to a representative temperature. Specifically mentioned is that the constant temperature data and the poultry hatching (optimal hatching chicken) standard 37.8°C are 0.5°C to 1.0°C higher than the standard, although it can not be said that the current artificial hatching pigeon is the most scientific, but it has absolute reliability. Not only can the hatching rate be the highest, but also the young pigeons have a good appearance of a high rate of fitness, and there is no belly-nail, and the eggshells after hatching are clean and satisfactory results are obtained.
Third, pay attention to control of humidity in the use of different humidity after many years of experimentation, learned that the appropriate humidity of the artificial hatching pigeon is about 10% lower than the hatching chicken. It is appropriate to control the humidity between 50% and 55% during the entire incubation period. Should pay attention to the humidity can not be too high, especially when a large number of pigeon eggs hatched, should not spray water on the unemerged embryos, such as hatching chickens and ducks as spray water humidification of 70% to 80%, the results of the hatching rate It will be very bad; the reason is that most of the young pigeons will swell in the shell when the box is under severe conditions of high temperature and high humidity. If the humidity during the whole incubation period is higher than 60% to 65%, it will hinder the evaporation of water in the pigeon eggs and affect the normal metabolic development of the embryos. It will make the hatching time even more different. The hatching young pigeons are weak, with large belly edema, protein sticking, and some can't die from pods. Sometimes the mouthfuls are very good or they suffocate in the shell. The above situation will change when you control reasonable humidity and pay attention to ventilation. 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. It can be seen that the embryonic air chamber is too large, the young pigeon's hair is short and dry and easy to adhere to the eggshell, the coat color is contaminated, and survival is low.
Fourth, improve measures
1, broken egg repair: the undischarged 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 fertility.
3, outside the box to dry the eggs: the eggs have been hatching older than 12 days old embryos, out of the egg cell outside the incubator to dry 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.
V. Conclusion
1, artificial hatching pigeons than the natural pigeon hatching hatching rate has greatly improved. However, compared with other poultry, it is still relatively low. Apart from genetic related to breeds, this is mainly due to long-term self-cultivation, inbreeding, age oldness, feeding and management, feed nutrition, health sand, dirty egg contamination, pigeon egg collection and storage. And other factors directly affect. If pigeon breeders overcome the above-mentioned unfavorable factors, the hatching rate will be greatly improved.
2, if the use of variable temperature hatching pigeons or hatching boxes out of the shell, will be more suitable for the development of embryos at all stages, limited to a small batch size of the hatching pigeons, pending further incubation for variable temperature incubation
