How to raise snails

Problems needing attention in artificial breeding of snails

Snails are omnivorous animals, which need a variety of nutrients in the process of growth and reproduction. The experiment shows that it takes 2 1 0 days to gain weight to 50g when feeding snails with single feed, but it only takes 150 days when feeding snails with compound feed, with a difference of two months. Therefore, to feed snails well, we must first scientifically prepare feed, and then pay attention to scientific feeding methods.

I. Types and characteristics of common feeds

1. Green feed, such as twigs and leaves of green plants, is the basic feed for snails and is rich in chlorophyll, plant protein, inorganic salts and vitamins.

2. Melon and potato feed, such as pumpkin, wax gourd, potato, sweet potato, etc., is rich in starch, sugar, minerals and moisture, crisp and juicy, and has good palatability.

3. Wheat bran, rice bran, corn husk and soybean husk are rich in starch, phosphorus, sulfur and vitamin E. ..

4. Oilseed meal feeds, such as soybean powder, sesame powder, bean cake and rice bran cake, can provide rich protein, oil and vitamin B.

5. Animal feed such as fish meal, bone meal and earthworm powder. Rich in protein, calcium and phosphorus, and complete in essential amino acids.

6. Inorganic feed includes bone powder, shell powder, silkworm excrement shell powder and shrimp shell powder which can provide rich calcium.

It should be pointed out that snails do not eat irritating foods such as onions, garlic, leeks and peppers. When feeding, toxic plants such as Euphorbia fischeriana, Radix Aconiti Kusnezoffii, Hypericum perforatum, Zeqin and Rhizoma Arisaematis should not be mixed.

Second, how to prepare feed

When preparing snail feed, we should not only consider the age, weight and physiological status of snails, but also pay attention to the following issues:

1. In the compound feed, the amount of green feed is more, and the amount of beans, grains and bran feed is less.

2. Feed with low price and high nutritional value should be selected according to regional and seasonal differences.

3. At least three kinds of feed should be selected when preparing feed to ensure complete nutritional components.

4. The prepared feed should not contain toxic and moldy substances.

Third, the feeding method

1. Snails eat a lot, accounting for about 4%-5% of their body weight every day. Generally speaking, the feeding amount should be higher than 4% each time, but not too much. It is best to eat before the next feeding.

2. Feeding frequency in hot summer is generally 1 time a day. Feeding in spring and autumn 1 day -2 days 1 time. If it is not hot in winter, you can feed enough feed before hibernation, and then feed enough feed after hibernation to restore your physical strength as soon as possible and grow and develop in time. If it is heated in winter, the feeding frequency can be controlled according to the temperature, which is generally 1 time, once every other day.

3. Feeding time Snails are active at night, so the feeding time should be arranged in the evening and there is no need to feed during the day.

4. Feeding methods It is best to choose a single variety for each feeding of vegetables, melon and fruit leaves and green plant stems and leaves to avoid the waste caused by snails eating only their favorite feed. Green feed can be placed directly on the feeding soil, or on the net woven with plastic rope, so that snails can feed themselves. Rice bran, wheat bran, fish meal and other feeds should be put in porcelain jars and placed in the middle of pools or boxes. The compound feed should be mixed with warm water in the basin first, and the amount of water should be held by hand, and dispersed immediately after loosening. Remember that the feed can't be put in an iron pot to prevent the iron pot from rusting and snail poisoning after eating.
