Treatment of calcium deficiency in cultured field snail

In the process of field snail culture, the most fear is the erosion of disease, so the prevention and treatment of disease in the process of breeding is very important. If the production of field snail culture is high, it is necessary to master certain disease prevention methods and disease prevention measures.

Etiology of calcium deficiency in field snail

Eating a single feed, resulting in calcium deficiency. The snail has strong resistance, less disease, high reproduction rate, and low requirements for breeding sites. Many ditches, paddy fields and ponds in rural areas can be stocked. If it is an open pond, red duckweed, duckweed, water hyacinth and other shade can be raised on the water surface, and bamboo poles and wood strips can be inserted into the pond for field snail habitat, which can not only receive green manure on water as feed, but also raise field snail to increase income.

Symptoms of calcium deficiency in field snails

The flesh of the snail overflowed to the outside or soft after contraction. Field snails are mostly propagated naturally, and can be picked up from paddy fields, Zizania caduciflora and muddy water ditches or bought in the market, and then fresh snails with light brown color, thin shell and blunt body and tail can be selected as species. Generally speaking, field snails weighing 15-25 grams can reach sexual maturity and reproduce above 15 ℃. The female snail is large and round, while the male snail is small and pointed.

Snails like to inhabit the water environment rich in humus in the sediment, such as lakes, ponds, marshes, field valleys or slow-flow river ditches with luxuriant water plants, often feed on microorganisms and humus in the soil and phytoplankton, young aquatic plants and moss in the water, as well as artificial fodder, such as fruits and vegetables, vegetable leaves, rice bran, wheat bran, bean flour (cake) and various animal scraps.

Feeding management of field snail

1. Snails: young snails should start feeding two weeks after delivery, and egg yolks should be used at the beginning. After 1 or 2 days, they can be allowed to eat natural bait, and when feeding, they should lick the bait with their teeth and tongue, so when feeding solid bait, they must soak in soft water to suit feeding.

2. Young snail: after the snail is put into the pond, it begins to feed green vegetables, rice bran, fish offal or tea cake, bean cake, etc., green vegetables and fish offal should be chopped and mixed with rice bran and other feed, and vegetable cake and bean cake should be soaked and softened to facilitate snail feeding.

3. Adult snail: the feed demand of adult snail can be divided into four periods in one year.

From March to May, ① is the preparation period before mating and begins to feed.

The period from May to the middle of August of ② is the period of spawning and hypertrophy. In the early stage, the appetite increases sharply, and in the later stage, the appetite is sometimes depressed due to the influence of spawning and high temperature.

From August to mid-October, ③ prepared for hibernation, increased appetite in the early stage, accumulated nutrients and prepared for hibernation. Before entering hibernation, its food intake decreases.

④ began to feed organic fertilizer the week before when spring came and field snails began to wake up after hibernation.

⑤ needs to be fed during the preparation period of spawning and hibernation, and it is appropriate to feed twice a week, and the amount of feed can be flexibly controlled according to the feeding and water quality of field snails.

⑥ field snail is most suitable for growth in the range of 20-26 ℃. When the water temperature is lower than 15 degrees or higher than 30 degrees, there is no need to bait.

Dietotherapy value of field snail

Tian snail, also known as Tian win, Tanaka snail, yellow snail. It is distributed in most areas of our country. After the meat of the Chinese round field snail or its fellow animals is obtained, it is raised in clean water to remove the mud and sand, or slightly boiled and shelled for meat bleaching. It has a dietotherapy effect on diseases such as red eyes, jaundice, beriberi and hemorrhoids, and it also has a significant effect on promoting diuresis and detumescence and treating body odor.

1. Clear eyes. Field snail is rich in vitamin A, and vitamin A can regulate vision, can be used to treat a variety of eye diseases, can prevent night blindness and vision loss.

2. High calcium content. As we all know, calcium is an important component to promote human bone development, which can directly affect the height.

3. Field snail contains a large amount of copper, which can supplement a large amount of copper to the human body, which has an important impact on the blood, central nervous system and immune system, hair, skin and bone tissue, as well as the development and function of brain, liver, heart and other internal organs.

4. The iron element in snail is suitable for the treatment of iron deficiency anemia.

Breeders in the breeding process, encounter the erosion of the disease should not be nervous, according to its symptoms, find its cause, and then the right medicine can play the effect of curing the disease, must not blindly use drugs, may also cause countereffect.
