Problems solved by technology

However, my country began to study artificial feed for silkworms in the 1970s and 1980s, and the progress has been slow. Because the cost of artificial feed for silkworms is higher than the income of silkworm cocoons, and the processing methods for processing and feeding are cumbersome and time-consuming, it has affected the artificial feed for silkworms. Promotion of Sericulture Technology
[0004] The water content of the current artificial feed is generally about 70%. Because it is rich in nutrients, it is easy to deteriorate (mainly lactic acid bacteria, yeast, mold), so it is often necessary to add sorbic acid and propionic acid to prevent bacteria and antibacterial, and sorbic acid 1. When the pH of propionic acid is between 4 and 5, its antiseptic effect is the best, so citric acid must be added to adjust the pH; in addition, the traditional silkworm artificial feed contains mulberry leaf powder, which is dried from mulberry leaves or bud leaves It is made by crushing again, the production cost is high, and the production process is cumbersome. It is necessary to build a special mulberry leaf powder drying processing plant, which greatly increases the cost. At the same time, during the drying process of mulberry leaves or bud leaves, the Vb Vitamins such as Vb and Vc are basically destroyed by high temperature, so a certain proportion of vitamins such as Vb and Vc must be added to the artificial feed of traditional silkworms. In addition, cellulose can make the artificial feed have certain physical properties, which is beneficial to silkworms and promotes food intake. The movement of the content in the digestive canal and the infiltration of the food by the digestive juice, so it is often necessary to add a certain amount of cellulose to promote the feeding, digestion and absorption of the silkworm and significantly improve the breeding performance
[0005] To sum up, it can be seen that the current artificial feed needs to add a lot of ingredients, which leads to the high cost of artificial feed
Therefore, aiming at the shortcomings of traditional artificial feed such as high cost, complicated feed processing procedures, labor-intensive silkworm rearing and low utilization rate of facilities, the inventor intends to develop an ultra-low-cost artificial feed for silkworm and its preparation and use method

Embodiment 1

[0031] An ultra-low-cost method for using artificial feed for silkworms, comprising the steps of:

[0032] A1: Artificial feed uses crushed pulp of fresh and tender mulberry branches with leaves, freshly squeezed lemon juice, soybean meal powder, flour, sucrose, agar powder and inorganic salts as the main raw materials, and is mixed by adding cold boiled water and kneaded into a dough-like mixture;

[0033] The crude protein content of mulberry leaves accounts for about 23% of the total dry matter. There are 17 kinds of amino acids in mulberry leaves, 6% of crude fat, 25% of soluble carbohydrates, 5-12% of crude fiber, and a large amount of Vitamin C, B1, B2 and folic acid, carotene, calcium, phosphorus, iron, manganese, sodium, etc., also contain a lot of flavonoids. In this embodiment, the mulberry leaf powder in the traditional silkworm artificial feed is replaced with the fresh and tender mulberry branch pulverized pulp, which reduces the drying process of the mulberry lea...

Embodiment 2

[0043] An ultra-low-cost artificial feed for silkworms and a preparation method thereof,

[0044] The artificial feed adopts fresh and tender mulberry branch pulverized slurry with leaves, freshly squeezed lemon juice, soybean meal powder, flour, sucrose, agar powder and inorganic salt as the main raw materials, and is mixed and kneaded into a dough-like mixture by adding cold boiled water; The proportion of each raw material in the artificial feed is calculated by mass fraction: soybean meal powder 36.86%-40.74%, flour 20.90%-23.10%, sucrose 4.75%-5.25%, agar powder 0.95%-1.05%, inorganic salt 2.85%-3.15%, The added amount of the mulberry branch pulverized pulp is 28.50%-32.50% by dry weight, and the added amount of freshly squeezed lemon juice is 0.05-0.25% by dry weight. The specific production method of artificial feed is as follows:

[0045] S1: Cut fresh and tender mulberry branches with leaves, mix the cut fresh and tender mulberry branches with fresh lemons according ...

Embodiment 3

[0060] According to the characteristics and physiological needs of silkworms, the raw materials in the traditional feed formula include mulberry leaf powder or mulberry bud powder to provide mulberry leaf components; soybean meal powder and corn flour to provide protein sources; agar for molding agents; citric acid for antibacterial preservatives and vitamins for physiological regulation; adding inorganic salts can improve the utilization of protein and amino acids by silkworms and reduce the excretion of uric acid; inorganic elements include potassium, phosphorus, zinc, magnesium, manganese, iron, calcium, etc.

[0061] In this embodiment, the silkworm artificial feed and the traditional silkworm artificial feed have been carried out a feasibility comparative test, and the silkworm artificial feed of the present invention is named B feed, and the traditional feed is named A feed, and the selected silkworm species for testing is Sichuan Silkworm 23 No., the test period is from ...

Abstract

The invention relates to the technical field of silkworm breeding, and discloses an ultra-low-cost artificial feed for silkworms and a preparation method and use method thereof. The preparation methodcomprises the following steps: kneading fresh and tender crushed mulberry twig pulp, freshly-squeezed lemon juice, soybean meal, flour, cane sugar, agar powder and inorganic salt into a dough-shapedmixture, extruding the mixture into strip-shaped artificial feed by an extruder, and laying the feed on a silkworm rearing bed for silkworm rearing. The fresh and tender crushed mulberry twig pulp isused for replacing mulberry leaf powder, the freshly-squeezed lemon juice is used for replacing a preservative, the soybean meal and other raw materials are added to prepare the artificial feed on site, heating and drying are not needed during preparation, the raw material and processing costs of the artificial feed are greatly reduced, and vitamins, food calling components and other nutrient substances in mulberry twigs and leaves cannot be damaged by high temperature; the tender mulberry twigs provide cellulose for the artificial feed, so that the feeding habit, main nutrients and physiological growth requirements of silkworms are met; and an atomization humidifier is used for humidifying silkworm breeding rooms, the problem that silkworms cannot eat due to the fact that artificial feedbecomes hard after moisture is evaporated is avoided, the input amount is reduced, and the cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of silkworm breeding, in particular to an ultra-low-cost artificial feed for silkworms and methods for preparing and using the same. Background technique [0002] As we all know, my country is the birthplace of silk production and a large country of sericulture. Both cocoon silk production and export trade volume account for more than 80% of the world's total, and 5000 years of traditional sericulture is to use mulberry leaves to feed silkworms. Limited by the growth period of mulberry trees, silkworms can only be raised from April to October every year. The utilization rate of sericulture equipment is low, and it is difficult to realize large-scale and industrialized uninterrupted sericulture all year round. And adopting artificial feed to raise silkworms can solve the problems referred to above, realize uninterrupted silkworms all year round. [0003] The research on artificial feed sericulture was first ...
