First, according to the experimental data, it is determined that the optimal temperature range for incubation in the whole period is to be incubated at a constant temperature, and the temperature can be flexibly varied from 38.3 degrees Celsius to 38.8 degrees Celsius depending on the regional climate. In particular, the constant temperature data and the standard of 37.5 degrees Celsius for poultry hatching (optimal hatching) are 0.5 degrees Celsius to 1.0 degrees Celsius higher. Although this is not the most scientific, it has absolute reliability. Not only can the hatching rate reach the highest and the young pigeons look beautiful and the hatching rate is high. There is no big belly belly, and the egg shells after hatching are clean and satisfactory results are obtained.
Second, after many years of experimentation, it was learned that the suitable temperature for artificial hatching pigeons was about 10% lower than that of hatching chickens. It is appropriate to control the humidity between 50% and 55% during the entire incubation period. Should pay attention to the temperature can not be too high, especially when a large number of pigeon eggs out of the shell, do not spray water on the unemerged embryos, such as hatching chickens and ducks as spray water humidification of 70% -80%, the hatching rate will be very Oops, the reason is that most of the young pigeons will swell in the shell when the inside of the box is under severe conditions of high temperature and high humidity. Should avoid the box space, the fan is too large, the humidity is too low to affect the hatching, can be seen in the embryo chamber is too large, young and short hair dry and easy to stick with the eggshell, hair color pollution, low survival.
Third, other measures
1, broken egg repair: will not clear the broken pigeon eggs with latex, egg white, tape (medical volume type), with the method of coating or post-filling inoculation. This single can increase the production of young pigeons by 3%.
2.Statistics of azoospermia: Embedding anaerobic dead embryos for detailed records and processing flirting pigeons at any time, which is very important to improve fertility.
3. Drying outside the box: Incubate embryos older than 12 days old and extract the egg cells outside the incubator. Incubate the new hatching eggs as usual in the original box. This method can solve the problems in constant temperature incubation and can greatly increase the hatching rate and the rate of hatching.
The natural hatching rate of artificial hatching pigeons and their relatives has greatly improved. However, compared with other poultry, it is still relatively low. Apart from being genetically related to breeds, it is mainly due to long-term self-cultivation, near-parent mating, ageing, feeding and management, feed nutrition, health sand, dirty egg contamination, pigeon egg storage, etc. Many factors directly affect. For example, pigeon breeders can overcome the above-mentioned unfavorable factors, which will greatly increase the hatching rate.
Cardiovascular disease is a serious threat to human, It is a common healthy disease especially in the elderly over the age of 50, even if used the most advanced treatment, there is still have more than 50% of cerebrovascular accident survivors can not completely self-care, The world's annual deaths from the disease as high as 15 million people, ranking the first cause of death. Cardiovascular disease is the number one disease that threatens human health. Currently anti-cardiovascular disease drugs mainly include cardiac drugs, anti-angina drugs anti-heart rate disorders drugs, antihypertensive drugs, anti-hyperlipoproteinemia drugs. Drug therapy is only a means of prevention, The fundamental is prevent from the source. Cardiovascular disease, in addition to being affected by genetic factors, mainly is associated with unhealthy lifestyles. Also known as lifestyle sickness. So the establishment of a healthy and reasonable way of life is the key to prevention.
