Artificial Hatchery Management Technology of Snake Eggs
1. Selection of Incubating Snake Eggs Snake eggs should be collected in snake gardens at any time during the spawning of snakes. In order to increase the hatching rate of fertilized eggs, the collected snake eggs should be selected before hatching. High quality snake egg shell is hard and full, elastic, shell color is slightly blue. If the eggs and eggs that do not meet the requirements are not suitable for hatching, they should be discarded.
2. Artificial hatching methods of snake eggs Most of the artificial hatching of snake eggs uses the cylinder hatching method, but also the pit hatching method. A small amount of snake eggs are hatched with wooden boxes. The method for incubation of snake eggs is described below.
Take a large-mouth pottery jar (can also be used for water tanks), put it in the room, coat the bottom of the tank with fresh sand, compact it layer by layer, and lay the thickness of sand to be 30-40 cm away from the cylinder port. For example, the egg hatching temperature of the barramundi is 19.2~32°C, and the relative humidity in the cylinder is 60%. The collected snake eggs are then placed side by side (to avoid vertical discharge). Taking the silver snake as an example, 70 to 80 pieces can be discharged every 35 cm square. Lay the clean moss on the eggs and keep the temperature between 20~30°C. Cover the mouth of the cylinder with a dark wet cloth. It is best to cover the cover. The cover not only keeps the temperature inside the cylinder stable, but also prevents Ants, rodents. Finally, move the incubator to a cool, ventilated place.
In order to balance the temperature and humidity in the incubator, the embryos should be properly exercised and turned over once every 7-10 days. The eggs should be handled lightly when they are flipped to avoid crushing and violent oscillation. The eggs of unfertilized eggs or stillborn fetuses will degenerate and rupture after a long time. The spillage of other eggs will cause other eggs to be affected. Therefore, attention should be paid to egg inspection in the process of artificially hatching snake eggs, paying close attention to each egg. The situation of the embryo. The development of in-ovo embryos can use the light to form a bundle of concentrated light through the small holes, place the snake eggs in the small holes to observe; or without light, drill a small hole in the plate against the sunlight; or make the sun through the mirror flat Place a hole in the plank to observe it. Early normal snake embryos showed a blood vessel distribution, the mid-snake head movement was more obvious, and the young snake's body dark shadow was seen later. The more obvious the later, the unfertilized egg and stillbirth were removed in time to prevent contamination of other snakes that were hatching. egg.
Snake eggs should be incubated every day during the incubation period. When the snake is hatched, the size and weight of the snake and the hatching conditions and the name of the snake should also be recorded. Generally, the incubation period of snake eggs is about 60 days, but it also differs depending on the type of snakes. For example, the incubation period of the snake is 40-47 days, the silver snake is about 45 days, and the cobra is 47-57 days. (usually about 50 days), barramundi is 26 to 29 days.
3. The albino snake hatches the snake's snout with ovoid teeth. Before hatching, the egg shell is cut open with a sliver and a thin seam is made. After passing through the snake snake, the snake is continuously stroked for about half an hour to one hour. Egg shells, snakes can escape from the cracks. In order to allow the snake to escape smoothly, the cracked snake shell is placed in a box filled with sand so that the escape snake can avoid being squeezed to death, and the snake can be quickly drilled into the sand after shelling. Hide your body and prevent it from getting hot or cold to survive the snake. Snakes are mostly shelled at night. When the artifacts strike the snake that has just emerged from the shell, the snake will instinctively impact the bite. After the shell was removed, snakes were plated around the egg shells, and individual cords were also dragged. Freshly hatched Aberdeen snakes can be transferred from the incubator to the young snake feeding tank to promote the absorption of the yolk on the third day. The animals are bred separately according to their sizes to prevent the weak meat from foraging their own food. They should be fed as soon as possible, and they can not be preyed on their own initiative. For frogs and mice, meat and viscera meats were fed on average 0.5 grams per snake for every 10 days. The snake starts the first molting after 10 days of incubation, and then 2-3 times per year.
