Management technology of artificial culture of Agkistrodon halys

Agkistrodon halys is one of the venomous snakes, often inhabiting mountains or plains, often disk-shaped or twisted into waves. It is covered with treasures, skin, bone, gallbladder, fat, molting can be used as medicine, snake venom is even more expensive, snake meat is also a delicacy on the table. Artificial breeding of Agkistrodon halys is a rich project with good economic benefits. The culture techniques are introduced as follows:

First, the construction of the snake farm should generally sit north to the south and tilt to the south to prevent stagnant water after the rain. The size of the site can be determined according to the number of animals raised. The wall requires a masonry structure, the wall is generally 2.5 meters high, and the inside of the wall should be smooth with cement to prevent snakes from climbing and escaping. The foot of the wall is 1-1.5 meters underground and poured with cement to prevent rats from making holes. Some small trees which are not easy to grow tall are planted in the field for snakes to climb and shade. The feeding density is generally 3 to 5 per square meter. 2. Breeding methods the reproduction, feeding and activity of Agkistrodon halys are all affected by air temperature. the optimum temperature is 20-30 ℃, less active when less than 10 ℃, and hibernating below 5 ℃. Every year from May to October is the active season. The humidity requirement is more than 55%. Agkistrodon halys are active at night and look for a lot of food before and after hibernation. After the warmth of spring, they come out one after another to look for food and mate. Most of them mate with oestrus before stinging. There is a gland at the base of the tail of Agkistrodon halys, which gives off a strong smell during the reproductive season. Male snakes use it to find females. After chase and stimulation, the two snakes are tightly twisted together in the shape of "twist", and the cloacal holes are close to each other. A male snake can mate and fertilize with multiple females, so the number of male snakes can be reduced appropriately. On the other hand, after mating, female snakes no longer mate with other males. The breeding method of Agkistrodon halys is different from that of other snakes. It propagates once a year from July to August, and gives birth to 2 to 8 offspring each time. The baby snake can live on its own after it is born. Newborn snakes shed their skin twice in that year, and then shed their skin regularly with the growth of the body. Third, the feeding method of Agkistrodon halys has a slow metabolism, and it will not starve to death if it does not eat for a few days or even dozens of days after satiety, but the water supply cannot be cut off. Agkistrodon acutus eats meat and is artificially fed with live rats, frogs, Loach, eel, insects, fish, birds and so on. Meat, chicken, duck and goose eggs can also be put into the breeding ground. You can raise some frogs in the field and let Agkistrodon halys swallow them at any time. It is generally fed 2 or 3 times a month. In case of food shortage or need to be full before winter, you can cooperate with the feeding of refined meat. During the activity, Agkistrodon halys should eat at least its own weight every month. The key to raising Agkistrodon halys is to do a good job of overwintering protection, the following methods can be used: 1. Container method: cover a layer of fine sand with a wooden box, put the dormant Agkistrodon halys on it, cover it with a layer of fine sand, and then put it in the 02nd ℃ cellar and move it back to the snake farm when it is warm in the coming spring. two。 Drilling method: drill a deep hole in the breeding site, wait for Agkistrodon halys to enter the hole through the winter, cover the hole with soil about 20 centimeters thick. 3. Pit pile method: dig a pit about 1.5 meters deep, pile up stones and dead grass in the pit, and let the snake climb in and cover the fine soil 20 cm. Remove the covered soil after the spring is warm, and let the snake climb out naturally. In addition, it is necessary to strictly prevent rats from biting Agkistrodon halys. There are three main methods of artificial culture of Agkistrodon halys: snake box culture, snake farm culture and natural area captive culture. Breeders can choose breeding methods according to the actual situation and conditions. In the process of raising snakes, the snake farm should be cleaned frequently to remove debris such as animal carcasses and residues. Snakes that are found to have diseases should be treated or eliminated at the right time. Attention should be paid to preventing the natural enemies of snakes from entering the snake farm. First-aid medicine for snakebite should be provided all the year round to prevent being bitten. Once bitten by Agkistrodon halys, you should immediately inject Agkistrodon halys antivenom and quickly escort the hospital to prevent accidents. Fourth, there are two methods for collecting snake venom: one is to bite blood, that is, one hand grabs the snake's neck, let the snake body let nature take its course on the workbench, so that it cannot twist, and the other hand sends the poison tool into the mouth of the snake, so that Jiao bites the poison tool, and the venom drips out of the venom teeth; the second is the membrane dish, that is, glass dishes with handles of both size and size, and large handle tubes communicate with the dishes in order to accommodate the venom of many snakes collected at the same time. Tie a plastic film into the dish and send the dish into the mouth of the snake. The snake will bite through the film and drop the venom into the dish, waiting for the snake to release and take out the glass dish. After the venom is collected, it should be treated with a vacuum dryer immediately. Dry poison should be sealed, moistureproof and protected from light.
