Artificial feed formula for 5-year-old silkworm larvae

Abstract

The invention relates to the field of artificial feed for silkworms, and discloses an artificial feed formula for 5-year-old silkworm larvae in order to solve the problem that the silk yield of silkworms bred with artificial feed is obviously lower than the mulberry leaf breeding level under the background of the prior art, and the artificial feed formula comprises the following raw materials in parts by weight: 25-45 parts of mulberry leaf powder, 10-25 parts of corn flour, 25-40 parts of soybean meal powder and 1.8-3 parts of a food preservative. And 1-3 parts of a vitamin additive, and also comprises an amino acid additive. The amino acid composition of the artificial feed is balanced by using glycine and threonine, and the conversion efficiency of the five-year-old silkworm larvae on the protein of the artificial feed is improved, so that the silk yield of the silkworms bred by the artificial feed is improved, and the silk yield of the silkworms bred by using the artificial feed is close to or exceeds that of the silkworms bred by using traditional mulberry leaves.

Description

Technical field [0001] The present invention relates to the field of silkworm artificial feed, in particular to a 5-year-old silkworm larva artificial feed formulation. Background [0002] Artificial feed factory silkworm breeding is artificial feed instead of traditional mulberry leaves, high-density, sterile breeding under controllable environmental conditions, factory production of silkworm cocoons, can greatly improve labor productivity and housing utilization, is a large-scale, standardized, intensive modern sericulture mode, in line with China's traditional labor-intensive sericulture industry transformation and upgrading needs. The nutrients of silkworm artificial feed mainly include: protein, fat, carbohydrate, vitamins, minerals, etc. The current artificial feed formula of silkworms can adapt to the eating habits of silkworms and meet the basic nutritional needs of silkworms, but the silkworm silk production capacity of human feed is low, and its silk production cannot r...

Problems solved by technology

[0004] In order to overcome the problem in the prior art that the silk production of silkworms raised with artificial feed is significantly lower than that of silkworms raised with mulberry leaves, the present invention provides a formula for artificial feed for 5th instar silkworm larvae. For the conversion efficiency of protein in the feed, increase the silk production of silkworms raised on artificial feed, so that the silk production of silkworms raised on artificial feed is close to or exceeds that of silkworms raised on mulberry leaves
