Toad, also called toad, is an animal with high economic value that combines medicinal and health care properties. It is known as "Toad Treasure". The following is the content I brought about toad breeding methods. Welcome everyone to read!
Methods of raising toads
1. Choose a breeding site
Choose a breeding site In places with ponds and pools, where insect sources are abundant and temperatures are warmer. Generally, waste ditches, waste ponds or puddles can be used in front of and behind the house, or rice fields with convenient drainage and irrigation, sufficient water sources, good water retention but thinness can be used as breeding farms. The farm should use bricks to build a 1.5-meter-high fence. Film or gauze can also be used as the fence. It can also be made of iron wire or hills to prevent toads from escaping. It is advisable to use plastic gauze as a water gate at the entrance of rice fields to prevent tadpoles from escaping.
2. Introduction
When the breeding volume is very small, toad breeding mainly depends on catching. Adult toads mostly leave their hibernation caves at the end of March or early April and slowly crawl out of the water. Toads like warm, dark, and humid environments. They usually live in the grass and caves beside ditches during the day, or in dark and humid places such as bricks and stone holes behind houses. They are generally difficult to find. On rainy days or after rain, they are often easy to catch in the open space by the river or along the pastoral path. During the spring plowing season, more toads appear in rapeseed fields, green manure fields, and on paths in rice fields, and you can catch them in large numbers at this time. Warm, calm nights are the best time to catch toads. Every evening for about 2 hours after dark until dawn the next day, toads come out to hunt for insects. You can catch toads at any time. At this time, the place with the most toads is the open space in front of and behind the house. They are especially active in the middle of the night. Sometimes there are several toads. You can catch dozens to hundreds of kilograms of toads in just an hour.
The capture method is to gently clamp the toad with a wider bamboo clip and put it into a bamboo basket or a wooden box with gaps. Do not put it into a closed container with a plastic bag to prevent it from suffocating to death. To capture at night, you can use a three-battery flashlight to shine a strong light on the toad so that it will not run away easily. Because toads have short limbs and poor jumping ability, they generally crawl slowly. Therefore, it is very easy to catch them once they are discovered. The ratio of male and female toads is generally 3 females and 1 male. The fertilization rate can reach over 90%. The stocking density is 1-2 pairs per square meter.
3. Feeding
The food of toads is mainly insects. Small insects include armyworms, ants, aphids, mosquitoes, stink bugs, chafers, weevils, small cutworms, and beetles. etc.; large insects such as mole crickets, large green leafhoppers, etc. In artificial breeding, black light lamps can be used to attract insects or artificial insect trapping can be used to solve the breeding problem. In addition, breeding algae and other plankton can also solve the staple food of toads. Pigs, cattle, human feces, vegetable scraps, kitchen wastewater, waste from slaughterhouses and food factories, fertilizer water or bran can also be invested in breeding and feeding. fields to cultivate water quality and promote the growth of algae and plankton. Flies can also be caught and salvaged manually to satisfy their needs.
IV. Reproduction
From the end of February to March every year, when the water temperature is between 11°C and 15°C, Chinese giant toads mate and lay eggs. Toads that wake up from hibernation usually mate at dusk. They are mostly concentrated on the banks of ponds or on aquatic plants and floating objects. The males sometimes cry out and sometimes move their bodies to look for females, who hear the sound and come there. Toads have a strong reproductive capacity, and an adult toad can lay 3-5,000 eggs a year. Artificial breeding requires timely collection of eggs, and the collected eggs should be placed in breeding ponds or paddy field breeding bases from buckets as soon as possible to avoid accumulation for too long and suffocation. The egg-laying density is generally 500 eggs per acre, with an average of 2,600 eggs per acre, that is, about 1.3 million eggs per acre. Under the condition of water temperature of 18℃-24℃, the fertilized eggs can hatch into tadpoles after 3 days and nights. The newly hatched tadpoles are fish-like in shape, with a tail and external gills. After the tadpoles open their mouths, they can be fed with a mixture of boiled egg yolks, steamed bun residue and vegetable leaves. After about a month, it can be seen that the tadpole emerges first from the hind limbs, and the forelimb buds are hidden by the gill cover, which is not obvious from the appearance. After the hind limbs are fully developed, the forelimbs appear before the tail begins to shrink. The tadpole's internal gills gradually shrink, and it begins to use its lungs. Breathing, the tail gradually shortens and disappears, and warty glands appear on the back. This is the young toad after metamorphosis. Young toads feed on small insects, and their feeding is basically the same as for adults.
The market prospects of toads
The toad venom and toad coat collected from toads have high medicinal value. Toad venom is processed from the white milk secreted by the postauricular glands on the head and skin glands on the back of the toad. It is a traditional and precious medicinal material in my country. Used as a medicinal material, it has the functions of strengthening the heart and diuresis, stimulating breathing, reducing swelling and resuscitating, detoxifying and curing diseases, anesthesia and analgesic. Toad coat is the cuticle film naturally shed by toads. It has the functions of clearing heat and detoxifying, reducing swelling and relieving pain, sedating, diuresis, aphrodisiac, and fighting cold viruses. In recent years, due to the increasingly severe ecological environment, the number of wild toads has decreased sharply. As the demand for toad venom and toad clothing continues to increase at home and abroad, toad breeding will be a project with broad prospects. Moreover, breeding toads has the following advantages: toads can thrive in paddy fields, vegetable fields, wastelands, swamps, slopes and woodlands. Toads feed on various insects and plankton, have strong reproductive capacity, and have relatively simple breeding techniques. Medicinal value of toad
Toad is an economic animal with high medicinal value. Its whole body is full of treasures! Toad venom, dried toad skin, toad clothing, toad head, toad tongue, toad liver, toad gallbladder, etc. are all medicinal materials.
The dried product of the white serous fluid secreted by the toad’s postauricular glands and skin glands is called toad venom. It is a precious Chinese medicinal material and contains a variety of biological ingredients. It has detoxification, swelling, pain relief, cardiotonic diuresis, It has anti-cancer, anesthesia, anti-radiation and other effects, and can treat heart failure, stomatitis, pharyngitis, sore throat, skin cancer, etc. Germany has used toad venom preparations for clinical treatment of coronary heart disease, and Japan uses toad venom as raw materials to produce "life-saving pills". More than 50 kinds of Chinese patent medicines, including China's famous Meihua Diangui Dan, Yili Yatong Pills, Xinbao, and Huachansu Injection, contain toad venom ingredients. Toad venom has advantages and disadvantages. It is very toxic and cannot be taken directly. It needs to be refined and processed! The efficacy and function of toad
It has a pungent taste, cool nature and is toxic. Returns through the heart; liver; spleen; lung meridian
Efficacy and function: detoxifies and dissipates stagnation; eliminates accumulation and diuresis; kills insects and eliminates malnutrition. Mainly used for dysentery; furuncle; hairy back; scrofula; malignant sore; swelling; edema; infantile malnutrition; tetanus; chronic cough and asthma
⒈Toad preparation can enhance myocardial contractility , increase cardiac output, reduce heart rate and eliminate edema and dyspnea, digitalis-like effect.
⒉ The blood pressure boosting effect of this product is rapid and steady, lasts for a long time, and can increase the blood flow of the kidneys, brain, and coronary arteries, which is better than epinephrine vasoconstrictors.
⒊The effect of local anesthesia was tested on the cornea of ??guinea pigs. After instilling the same amount of medicine into the eye, stimulate it 6 times every 5 minutes for a maximum of 30 minutes. Count the number of times the cornea does not react within 30 minutes after stimulation. Taking the percentage of non-response as an indicator of the local anesthetic process, it was found that most of its local anesthetic effects are stronger than those of cocaine.
