Heron hatching and brooding

Heron's hatching and brooding. Agricultural Bureau of Shanting District, Zaozhuang City, Shandong Province. April 4, 2004 Heron can be used as a fishing tool in rivers and reservoirs. A heron has a lifespan of more than 20 years, and the best fishing period is at least 8 to 9 years. Therefore, the economic benefits of herding herding fishing are high and it is a road to prosperity.
The breeding of good herons is the first step in the development of heron fishing and its technical requirements are very high.
1 Grasp the mating period, and make sure that there is a small white spot on the top of the mouth where the egg is born. A female heron, who has been raised for 3 years, will be able to produce eggs. Usually, more than 20 eggs can be produced each year in the late winter and early spring, and the size and duck eggs are normal. The female egret has lazy reluctance to fish before laying eggs, and the mating method is generally maintained with 1 female heron and 2 male herons, which can promote multiple matings. It is best to use hatching eggs at about 23 o'clock, which has the strongest vitality and the highest survival rate. However, eggs produced during daytime fishing have poor hatching effects.
2 Hatching and artificial hatching of hens and hatching by artificial hatchery usually do not hatch after laying eggs, and hens must be used for hatching. After 24 to 26 days of hen hatching, the eggs begin to pout, and if they do not pout more than 28 days, they are useless eggs. After the hatching of the hen, it is necessary to remove the eggs and put them on a fire pot for artificial hatching. The temperature is maintained at 25-28°C. After hatching for 2 weeks, the little heron can hatch.
3 Fine management ensures that the living heron will be closed and the eyes will be tightly closed. The whole body will be hairless. It can be placed on the batting and heated under the fire. The temperature is maintained at about 22°C. Attention should be paid to observing the pupa situation of the little heron after birth. After discovering the pupa, it is necessary to feed the heron with a little loach. If you do not pull it, it means that if you do not digest it, do not feed it. After feeding, they were fed 2 or 3 times a day and each time they were fed with 1 small loach. After 1 week, they could feed some small fish; 2 weeks later, they would open long-haired eyes; 3 weeks began to grow bristles; 4 weeks later they began to stand and walk. After the unbred little heron is pulled, it should be covered with cotton wool to keep the sleeping nest clean and hygienic. After half a month of feeding, the little heron will automatically pull it out of the sleeping quarters. During the brooding process, the herons have to pay attention to the temperature and feeding, and find that the squeaking of the pupa is to feed 1 time and feed 2 to 3 times a day, feeding 1 small loach or small fish each time. As long as it is carefully managed, the little heron generally does not get sick. After 4 months of breeding, you can go fishing on the river. After going into the water, if it is poisoned by pesticides in the water, tetracycline and atropine can be used to treat the disease.
