Silkworm feed and preparing method thereof

Abstract

The invention provides silkworm feed and a preparing method thereof, and relates to the field of silkworm cultivation. The feed is prepared from lecithin, asparagus leaves, fishbone, sweet potatoes, tomatoes, citric acid, choline chloride, immunopolysaccharide, zeolite powder, soybean protein isolate powder, folium mori, elm tree leaves, fig leaves and preservative. The raw materials of the silkworm feed are easy to obtain, have the antibiosis and virus inhibiting functions and have the function of keeping the feed fresh. The silkworm feed can ensure nutrition needed by growth and development of silkworms, improve the disease-resistant capacity of the silkworms particularly young silkworms and enhance immunity, the young silkworms develop uniformly, and the incidence rate and the death rate are low. As the silkworms in different growth and development stages have different requirements for nutritional ingredients, the content of each ingredient can be appropriately adjusted according to needs when the silkworm feed is used.

Description

technical field [0001] The invention relates to the field of silkworm breeding, in particular to a silkworm feed and a preparation method thereof. Background technique [0002] my country is a big country for planting mulberry and sericulture. Sericulture is a labor-intensive industry that consumes a lot of labor. Silkworms can produce silk. Silk is a continuous long fiber that is solidified by secreting silk liquid when cooked silkworms make cocoons. It is also called "natural silk". ". Like wool, it is one of the earliest animal fibers used by humans. According to different foods, it is divided into silkworms, tussah silkworms, cassava silkworms, camphor silkworms, willow silkworms, and celestial silkworms. The thread drawn from a single silkworm cocoon is called cocoon silk, which is made of two single fibers bonded and covered by sericin. The cocoon silk of several silkworm cocoons is drawn out, and the silk strips formed by bonding and wrapping with sericin are divided...

AI Technical Summary

Problems solved by technology

In addition, in the process of raising silkworms, the food of silkworms is relatively simple, usually mulberry leaves, which brings about a big problem. First, the shelf life of mulberry leaves is short, and it only takes a few days to store them in the refrigerator. Second, When there is a shortage of mulberry leaves, especially in cities, mulberry leaves cannot be found. Because silkworms only eat mulberry leaves, the baby silkworms will starve to death. Third, mulberry leaves are easily polluted by pesticides and poor air environment. If they eat them, they will be polluted The mulberry leaves are easy to be infected, and the young silkworms eat the contaminated mulberry leaves, which will lead to abnormal development and even poisoning death. As a result, the disease began to develop at the fifth instar stage, causing economic losses to farmers
