What are the main components of snake venom? A detailed guide
Snake venom is characterized by a complex composition. The toxic components still differ to some extent among different snake species, subspecies, and even the same species of snake in different seasons. Through the separation and purification of snake venom, the main components currently known include neurotoxins, cardiotoxins, coagulant toxins, hemorrhagic toxins, and enzymes. In addition, it also contains some small-molecule peptides, amino acids, carbohydrates, lipids, nucleosides, biogenic amines, and metal ions; some of these have biological activity, or are related to biological activity to some degree. After purification, the toxic components of snake venom can be 5-20 times more potent than crude venom.

What are the storage precautions for dried snake venom?
Dried snake venom is highly hygroscopic and not heat-resistant. Under the influence of high temperature, moisture or sunlight, it tends to deteriorate and lose its enzymatic activity. Therefore, the following points must be done well to preserve it for the long term. (1) After the dried snake venom is weighed, it should be put into an amber or brown bottle as soon as possible, the mouth of the bottle tightly stoppered with a cork, and then sealed with wax or vacuum oil. For large bottles of dried venom, in order to minimize unnecessary opening, some can be taken out and sealed in sample bottles before sealing, so as to be available for inspection at any time or to satisfy small occasional customers; the weight can be packaged as appropriate.

How should a snake house for the banded krait be built?
For artificial rearing of the banded krait, a snake garden or snake house can be used; for keeping a small number, a snake box can be used. The snake garden or snake house for the banded krait should be built in a sheltered, sunny place with high, dry ground and dense soil, close to a water source yet far from residential areas, and in a quiet spot. The snake garden should simulate the wild environmental conditions of the banded krait. The wall around the snake garden should be 2.5 m high, the inner surface of the wall should be smoothed with cement, the corners of the wall should be built in a rounded arc shape, the wall foundation should extend 1.5 m underground, and at a soil depth of 1.5 m it should be rammed solid with lime-sand-clay mixture to prevent rodents from burrowing and the snakes from escaping. The ground of the snake garden

Autumn Snake Rearing Methods and Key Technical Points
As the saying goes: "When the autumn wind blows, the three snakes grow fat." This accurately reflects the growth of snakes. In autumn and winter, snake farms should pay attention to the following points: 1. September to October is the peak predation season for snakes, during which they store large amounts of fat to safely survive the severe winter and maintain their nutritional needs until they emerge from their burrows the following year, so large amounts of food should be provided. 2. For snakes in relatively poor health, they can be sold on the market early rather than kept for overwintering. 3. In autumn, snakes are busy foraging and have more opportunities to emerge from their burrows, making them easier to capture in the wild, so precautions should be taken against predators.

What are the methods for fattening snakes? A full analysis of practical breeding techniques
Autumn is the season when snakes eat heavily, and it can be said to be the peak feeding period of the year for snakes. Therefore, fattening work in artificial snake farming in autumn is especially important, and it is also a "critical period" in snake management. The following work must be done well to achieve the goal of fattening. (1) Thoroughly clear the snake enclosure. In autumn, for the convenience of feeding or for snakes to better receive sunlight and thus facilitate food absorption and digestion, weeds that provided shade and cooling for the snakes in summer must be partially cut or selectively pulled out. When cutting with a sickle, do not leave it too far from the ground; it should be about

How many snakes are needed to collect 1 gram of dried venom?
The venom output of different species of venomous snakes varies greatly. Comparing the venom they discharge by dry venom rate, the king cobra averages 101.9 mg per bite, the sea snake only 2.5-5.0 mg, and the many-banded krait 4.6 mg. That is to say, the venom output of the king cobra is 41-20 and 20 times that of the sea snake and the many-banded krait respectively. Obviously, the king cobra's venom output is so large that obtaining 1 gram of its dried venom is easy, requiring only about 10 snakes. However, to obtain 1 gram of dried venom from a sea snake or a many-banded krait, it would take 200-40
