Problems solved by technology

Defatted soybean powder is an excellent protein source for silkworms, and is an important raw material for preparing artificial feed. However, soybean powder contains repellent substances that have adverse effects on silkworm feeding and growth. However, the composition of repellent substances is still inconclusive. The method then thinks that methanol, ethanol, hot water, etc. can be used to extract and remove some food-ingesting repellent substances, improve the silkworm's feeding ability to artificial feed, and promote its growth and development. However, methanol is harmful to the human body and has poor operability. Simply using ethanol Or the effect of hot water extraction is not ideal enough, and it will still affect the feeding and growth of silkworms

Embodiment 1

[0031] An artificial feed for juvenile silkworm silkworms with improved hair thinning rate. The raw material components and their mass percentages are as follows: 45% mulberry leaf powder, 30% extracted soybean powder, 5% green branch powder, 13% starch, and compound VB1.5 %, VC1.5%, citric acid 2%, dextrin 2%.

[0032] Preparation method, the steps are as follows:

[0033] (1) fresh mulberry leaves are dried and crushed through an 80-mesh sieve to obtain mulberry leaf powder, and fresh mulberry green branches are dried and crushed through an 80-mesh sieve to obtain mulberry green branch powder;

[0034] (2) Degreased soybean powder is crushed to 0.1-0.2 mm, and extracted with intermittent stirring with ethanol with a mass concentration of 70-95%. The weight-to-volume ratio of defatted soybean powder to ethanol is: 1:10-1:20, unit: g / mL ;Extraction temperature is 50°C, stirring and extraction time is 8h, and drying at low temperature after filtration;

[0035] (3) Then extra...

Embodiment 2

[0039] An artificial feed for juvenile silkworm silkworms with improved hair-thinning rate. The raw material components and their mass percentages are as follows: 45% of mulberry leaf powder, 30% of extracted soybean powder, 5% of green branch powder, 14% of starch, and compound VB1.5 %, VC1.5%, citric acid 2%, dextrin 1%.

[0040] The preparation method and breeding method are the same as in Example 1.

experiment example

[0059] The juvenile silkworms of the silkworms in Examples 1-2 and Comparative Examples 1-6 were raised artificially, and the juvenile silkworms were raised according to the breeding method and conditions of Example 1. Investigate the 24h thinning rate respectively, and the survey results are shown in Table 1.

[0060] The 24h thinning rate (%) of Lu 17 in Table 1

[0061]

[0062] As can be seen from the table above, the hair thinning rates of Examples 1 and 2 are all higher than those of Comparative Examples. Comparative example 6 uses common commercially available soybean powder, and does not contain dextrin in the component, and has the lowest hair thinning rate. 3, 4, and 5, compared with Comparative Example 6, although the hair-thinning rate has been improved to a certain extent, it is still far less than the hair-thinning rate of Examples 1 and 2 of the present invention. Comparative Example 3 only uses hot water to extract soybeans powder, comparative example 4 on...

Abstract

The invention relates to a young domestic silkworm artificial feed capable of improving setae dispersion rate and a preparation method thereof. The young domestic silkworm artificial feed comprises the following raw materials and components in percentage by mass: 40-50% of mulberry leaf powder, 25-35% of soybean powder which is extracted by ethanol and water twice, 4-5% of mulberry green shoot powder, 9-16% of starch, 1.5-2% of complex VB (vitamin B), 1-2% of VC (vitamin C), 2-3% of citric acid, and 1-2% of dextrin. The young domestic silkworm artificial feed has the advantage that the artificial feed is prepared by the soybean which is extracted by ethanol and water twice, and the dextrin is added into the feed, so that the setae dispersion rate is improved.

Description

technical field [0001] The invention relates to an artificial feed for juvenile silkworm silkworm with improved hair thinning rate and a preparation method thereof, belonging to the technical field of feed for insect breeding. Background technique [0002] Silkworm breeding with artificial feed is an epoch-making new technology in the history of sericulture. It is not restricted by seasons and climates. The feed is sterilized and sterile, and the quality is controllable. It is more in line with people's needs for food safety, and it can realize silkworm production. Mechanization and factoryization, improve production efficiency. The research on artificial feed for juvenile silkworms in my country began in the 1970s, but due to various factors, so far, artificial feed silkworm breeding is still in the laboratory and rural pilot stages. [0003] The feeding ability of silkworms to artificial feed is one of the key indicators for evaluating artificial feed, silkworm species an...
