Description
Technical Field
The invention belongs to the technical field of feed processing, and particularly relates to a compound feed for field snails and a preparation method thereof.
Background
River snail is rich in nutrients, vitamins, calcium, iron and other essential elements, is superior to chicken, duck, goose and crucian, and has the functions of nourishing Yin, invigorating Yang, improving eyesight, restoring consciousness, strengthening muscle elasticity, smoothing skin, etc. River snails are used as medicated food and edible food in the ancient times, and are particularly popular with food made of river snails as materials at present. With the increasing demand of the market on the river snails, the artificial breeding of the river snails is driven, and the artificial breeding mainly comprises the feeding of the cucurbit pepo leaves or the selective purchase of fermented feed with a single formula and the like. Because the rapid growth and propagation of the river snails need certain calcium nutrition, the artificial feeding of baits with unbalanced nutrition proportion often causes the lack of calcium and protein nutrition, and the yield and the quality of the river snails are directly influenced to a great extent. The market has not seen a special compound feed for feeding the river snails; the existing river snail feed is single in variety and incomplete in nutrition, and the feed is easily dissolved in a water body to cause the suspension of part of the feed in the water body, so that the river snails living in the lower layer of the water body are inconvenient to eat, and the feed is placed in water for a long time, and the palatability of the feed is deteriorated, so that the utilization rate of the feed is low, and the feed coefficient is increased.
Disclosure of Invention
The invention aims to provide a river snail compound feed which has good palatability and is not easy to dissolve in water.
The invention also aims to provide a preparation method of the feed.
The purpose of the invention is realized by the following technical scheme:
the field snail compound feed is characterized in that: the compound feed for the river snails consists of 18 weight percent of flour, 9 to 21.2 weight percent of soybean meal, 15 weight percent of rice bran, 1 weight percent of fish meal, 9 to 23.7 weight percent of rice protein powder, 14.9 to 41 weight percent of corn starch, 1 weight percent of adhesive, 1.8 to 2 weight percent of monocalcium phosphate, 2 weight percent of shell powder, 0.3 to 0.9 weight percent of soybean oil, 0.1 weight percent of choline chloride and 1 weight percent of multi-vitamin and multi-mineral premix.
Further, the binder is microcrystalline cellulose.
Preferably, the mixed feed for the escargots consists of 18 weight percent of flour, 16.4 weight percent of soybean meal, 15 weight percent of rice bran, 1 weight percent of fish meal, 17.8 weight percent of rice protein powder, 25.2 weight percent of corn starch, 1 weight percent of adhesive, 1.9 weight percent of monocalcium phosphate, 2 weight percent of shell powder, 0.6 weight percent of soybean oil, 0.1 weight percent of choline chloride and 1 weight percent of multi-vitamin multi-mineral premix.
Preferably, the mixed feed for the escargots consists of 18% of flour, 18.8% of soybean meal, 15% of rice bran, 1% of fish meal, 20.8% of rice protein powder, 20% of corn starch, 1% of adhesive, 1.8% of monocalcium phosphate, 2% of shell powder, 0.5% of soybean oil, 0.1% of choline chloride and 1% of multi-vitamin multi-mineral premix in percentage by weight.
Preferably, the mixed feed for the escargots consists of 18 weight percent of flour, 21.2 weight percent of soybean meal, 15 weight percent of rice bran, 1 weight percent of fish meal, 23.7 weight percent of rice protein powder, 14.9 weight percent of corn starch, 1 weight percent of adhesive, 1.8 weight percent of monocalcium phosphate, 2 weight percent of shell powder, 0.3 weight percent of soybean oil, 0.1 weight percent of choline chloride and 1 weight percent of multi-vitamin multi-mineral premix.
Further, the multi-dimensional multi-mineral premix comprises per kilogram of complete feed: 10mg of copper, 120mg of iron, 30mg of zinc, 20mg of manganese, 30mg of magnesium, 10mg of selenium, 20mg of iodine, vitamin A-508 mg, 3-502mg of vitamin D, 28mg of nicotinic acid, vitamin E-50100mg, vitamin K36 mg, vitamin B14.5mg, vitamin B26mg, vitamin B123 mg, vitamin B66 mg, 1mg of folic acid and 60mg of vitamin C.
In the river snail compound feed, the raw materials have the following effects:
flour: has water resistance, binding effect, palatability increasing, and carbohydrate ratio adjusting.
Bean pulp: provides rich crude protein and amino acid, and improves palatability.
Fish meal: contains high-quality protein.
Rice protein powder: increasing the protein content.
Corn starch: it is rich in sugar, vitamins and dietary fiber.
Rice bran: essential fatty acid is provided, and vitamins are increased.
Calcium dihydrogen phosphate: supplementing mineral nutrients such as phosphorus and calcium, and maintaining balance of calcium and phosphorus. Improve the absorption and utilization rate of various nutrient substances and promote weight gain and survival rate.
Shell powder: contains a large amount of calcium carbonate and a small amount of chitin, and can harden the shell structure of river snail.

Choline chloride: promoting growth and development, regulating fat metabolism, supplementing amino acids, etc.
Multi-vitamin multi-mineral premix: supplementing trace elements such as vitamins and minerals.
The existing pellet feed is easy to dissolve in water when being put into water, so that most of the feed is dispersed on the surface of the water body or suspended in the water body, and the feed can not be effectively utilized while the nutrition taken by the escargots which are positioned at the bottom of the water body and can only take the feed deposited at the bottom of the water body is unbalanced; thereby leading to higher feed coefficient and increased cost; meanwhile, as the feed is dissolved in water and suspended in water or is not eaten for a long time, the water quality of the raised escargots is damaged, and the survival rate and the growth condition of the escargots are finally influenced.
Besides providing corresponding nutrients, the components of the feed provided by the invention are reasonably combined with microcrystalline cellulose, flour and corn starch, so that the bonding capability of the feed is enhanced, and the hydrophobicity of soybean oil is combined, so that the feed is prevented from being dissolved in water and suspended in water, has remarkable stability, can be completely deposited at the bottom of a water body and is completely ingested by field snails in the lower layer of the water body, and the aim of balanced intake of the nutrients is fulfilled. However, when the feed keeps excellent binding capacity in water, the problem that the feed is difficult to eat and digest by the river snails easily occurs correspondingly, and the invention effectively promotes the decomposition, digestion and absorption of the ingredients in the feed by the river snails through the matching of the ingredients in the feed. The feed of the invention is quickly digested and absorbed after entering the river snail body, thus solving the problem that the feed is not easy to be decomposed and digested due to strong adhesiveness. The nutritional ingredients of the feed are fully absorbed by the river snails, and the balance of nutrition is achieved.
The preparation method of the escargot compound feed is characterized by comprising the following steps of:
(1) respectively crushing flour, bean pulp, rice bran, fish meal, rice protein powder, corn starch and shell powder, and controlling the crushing particle size by using a 80-mesh screen;
