Method for treating silkworm egg comprising shot-term refrigeration, high temperature impact and acid immersion

A technology of high temperature and silkworm eggs, which is applied in animal husbandry and other fields, can solve problems such as early delivery date, insufficient supply of early autumn seeds, variety layout of silkworm breeding farms, and difficulty in arranging the harvesting date of ants, so as to achieve good social and economic benefits and shorten Refrigeration time, the effect of solving the contradiction between supply and demand

Problems solved by technology

First of all, the refrigerated and pickled species produced in spring usually need to reach 40 to 50 days to obtain the ideal hatching effect, which brings certain difficulties to the layout of silkworm breeding farms and the arrangement of the date of harvesting ants; moreover, with the In recent years, due to changes in the natural climate, the layout of sericulture in rural areas has also changed. The release date of silkworm eggs in early and mid-autumn generally tends to be earlier, and the serious shortage of seed supply in early autumn has become increasingly prominent.

example

[0009] Example: Experiment with the Suwu×Suliu and Suliu×Suwu breeds that are raised on a large scale at present.

[0010] In the example, all the species participating in the experiment lay eggs on the same day, and the spawning time is controlled within 6-8 hours. After laying eggs, protect them at 24-26°C, put them into storage for about 50 hours and refrigerate them at 5°C, and treat them according to the four factors shown in Table 1: the number of days of storage, the number of exposure to high temperatures after leaving the storage, the time of exposure to high temperatures, and the time of pickling . After the treatment, the silkworm eggs were protected at 25°C and accelerated greening until they hatched. Continuously investigate the number of hatching grains for six days, calculate the practical hatching rate on the third day and the general hatching rate on the sixth day, and use the practical hatching rate as the main analysis index.

Abstract

The invention discloses a method for treating silkworm egg comprising shot-term refrigeration, high temperature impact and acid immersion which comprises the following procedures, first protecting the silkworm ovum for 50 hours at 24-26 deg. C, then refrigerating the silkworm ovum in 5 deg. C cool warehouse for 20-30 days, and warehouse-out after refrigeration period ends, high temperature impacting for cooling down 1.5-2.5 hours at the condition of 28-40 deg. C, finally carrying out pickling treatment with 1.092-1.094 of specific gravity, 46-48 deg. C of hydrochloric acid to obtain the silkworm seed.

Description

Technical field [0001] The invention relates to a method for treating silkworm eggs, in particular to a method for pickling silkworm eggs in short-term cold storage and exposed to high-temperature shock. Background technique [0002] In recent years, the early and mid-autumn seeds of sericulture generally use duplex refrigerated species. Due to the long refrigerated time of duplex refrigerated species, the increase of hatching rate has been affected to a certain extent. Instead of compound refrigeration. First of all, the refrigerated and pickled species produced in spring usually need to reach 40 to 50 days to obtain the ideal hatching effect, which brings certain difficulties to the layout of silkworm breeding farms and the arrangement of the date of harvesting ants; moreover, with the In recent years, due to changes in the natural climate, the layout of sericulture in rural areas has also changed. The date of delivery of silkworm eggs in early and mid-autumn generally te...
