Breeding technology of toad

Abstract: toad, commonly known as toad, refers to amphibian, Bufonidae animals. Toads eat insects, snails and other small animals, which are good for crops. Toads deter attackers by inhaling, inflating their bodies and propping them up on four legs.

The living habits of Toad

Like to hide in mud caves, under wet stones, in the grass, by the edge of the ditch. The skin is easy to lose moisture, so it is more latent and hidden during the day, and comes out at night and dusk. Most of the adult toads survive the winter in underwater sediment or under land moist soil. Stop eating, store sugar in the liver in the body to maintain the lowest metabolism, and do not end hibernation until the temperature rises to 10: 20 ℃ the following year. Prey and move at night, feeding on beetles, moths, snails, maggots and so on. Breeding in captivity is easier than other frogs.

Artificial culture of toad

1. Construction of the farm: a fence with a height of one to 1.5 meters will be built around the breeding site, which can be equipped with culture ponds, spawning ponds and incubation ponds. There should be lawns or vegetable plots around the breeding pond for toads to hunt and perch, and lights should be installed to attract insects to prey at night.

2. Reproduction: toads lay eggs and have strong reproductive ability. Every year, when the water temperature is about 10 degrees Celsius and the air relative humidity is 90%, each female lays about 5, 000 eggs at a time. The eggs are generally arranged in pairs in a tubular glial egg band, which is wound around the aquatic grass. The egg band can be placed in the incubation pool for artificial hatching. Keep the water temperature above 10 degrees Celsius when hatching, and adjust the water depth and control the water temperature at any time. In case of cold spell, storm and other bad weather, plastic film can be used to cover the heat preservation.

3. Management: toads should be fed in ponds and groups according to their different developmental stages to maintain sufficient bait. The bait of young toads is plankton, which can put pig and cow dung, vegetable scraps, wastes from slaughterhouses and food factories and bran into the pond to cultivate plankton; adult toads mainly feed on insects. It can plant all kinds of plants in the farm and lure insects with light at night, and it can also accumulate stable manure in the farm to breed insects to provide food for it.

Strip collection technology of toad

The toad takes off its shell once or twice a year, grows up once, eats it while taking off its shell, and eats it all after shelling. So people only know that there are toad clothes and it is difficult to collect them. After the Qingming Festival, toads successively come ashore to feed on amaranth and breed, and Grain in Beard is the best time to collect toad clothes, because from landing to Grain in Beard, the period of reproduction, rest and replenishment has been basically completed, and the temperature has reached more than 25 ℃. Earthworms and insects have multiplied in large numbers, have a wide range of food sources, and the toad body is strong, so we should immediately prepare the specific work of collecting toad clothes.

1. The indoor glass enclosure is 2.5 meters wide, 1.5 meters wide and 5 meters high. There are 5 stripper pools with cement polish on the bottom and a certain slope. Each pool is equipped with sewers for easy flushing. Lighting equipment is installed on the top of each pool for lighting at night.

2. Put the toad with more than 100 grams, complete limbs and no scars on its abdomen and back in the culture pond, rinse the soil and dust on its body with clean water, and spray pure traditional Chinese medicine preparation "stripper" after the water is dry. Desquamation usually begins one hundred hours after spraying stripper, that is, four days.

3. Observe all kinds of symptoms before taking off. Generally speaking, when you take off your clothes, you will be out of group, stay alone, slow to react, wet and shiny, etc., and start undressing in about ten minutes.

4. When toads take off their clothes, they usually start from the back, followed by the head, hind legs, abdomen and front legs. When it has taken off its three legs, that is, when the rest of the part has been taken off, and there is still a front leg, immediately grab it with your hand, gently pull down the rest, and remove its mouth. Gently take out the parts that have been eaten but have not had time to swallow together to make a complete toad clothing.

5. the clothes that have just taken off have mucus, so you should rinse them with clean water immediately, and then use stainless steel tweezers to gently pull the toad clothes on the glass 25 cm long and 12 cm wide prepared in advance to make a specimen-like appearance. Pull the specimen with light force, do not break it or cannot pull it, otherwise it will affect the quality of the goods. After the specimen is made, it is cooled and dried indoors, or dried in an infrared disinfection cabinet. Generally, 90% of the dry is the finished product, which is sealed and preserved or sold.

6. When two undressed toads are placed in another pool, the toad venom is scraped or put back into the culture pond after drying. If the food is sufficient and the food is raised properly, the toad can be taken out again in autumn or before hibernation, but the clothes that have been stripped can no longer be taken off in a short period of time. Because the clothes taken off in less than four months are thin and have great medicinal value, they are difficult to be organized and shaped, and have no commercial value.

Collection and processing technology of Bufo bufonis

1. Crisp clip: the crisp clip can be purchased from the medicine company for copper, aluminum or homemade bamboo clips. Select a section of high-quality bamboo tube with a length of 20 cm and a diameter of 5 to 7 cm, split into two halves, and on the same side of the two halves, connect them with hinges (iron hinges should be installed on the outside of the bamboo tube), and then install a tension spring on the outside. When the hand is loosened, the bamboo tube is divided into two halves due to the pulling force of the spring. In this way, the crisp clip will be ready.

2. Collection: the time to pick up the crisp is to harvest the wheat every year until late autumn, net or catch, and then concentrate on collecting the crisp. When taking the crisp, first wash the soil from the toad, cool and dry the water, and then clamp the retroauricular gland with a crisp clamp. with a proper squeeze, there will be a white prize liquid sprayed on the inner wall of the crisp clip, which will not be too strong, otherwise it will cause bleeding and pollute the toad to reduce its appearance quality. the edge of the crisp clip is too sharp and often causes bleeding, and the edges of the crisp clip can be properly polished. After the glands behind the left and right ears of the toad are removed, the toad can still grow normally. Generally, the toad should be placed in the field and lawn 50 meters away from the pond. Do not immediately put it into the water, so as to avoid wound infection, suppuration and death. Orchards and vegetable fields with pits and ponds can also be artificially stocked with toads and combined with cultivation and mining, which can not only use toads to eliminate pests, but also collect toads to increase income.
