Feed for improving the of Macrobrachium rosenbergii and a production method of feed

Abstract

The invention provides a feed for improving the yield of Macrobrachium rosenbergii and a production method of the feed. The feed comprises the following raw materials in part by weight: 40-50 parts of bone meal, 10-12 parts of soybean meal, 5-8 parts of earthworm powder, 1-5 parts of rice bran, 1-5 parts of wheat flour, 2-5 parts of beer yeast, 1-2 parts of soybean oil, 0.5-1 part of calcium dihydrogenphosphate, 1-2 parts of peanut meal, 2-3 parts of blood powder, 0.5-1 part of vitamins, 0.1-0.5 part of zeolite powder, 1-2 parts of fish oil, 1-2 parts of shell powder, 1-2 parts of amino acid, 1-2 parts of squid meal and 2-6 parts of silkworm pupa. The feed is good in palatability and easy to digest and absorb, can promote the growth of fish and shrimps, and can improve the immunity.

Description

technical field [0001] The invention relates to the aquaculture industry, in particular to a feed and a processing method for increasing the yield of Macrobrachium rosenbergii. Background technique [0002] Shrimp is the earliest export-oriented aquaculture species developed after my country's reform and opening up, and it occupies an important position in my country's aquaculture industry. In 2009, the national shrimp farming output exceeded 1.3 million tons, accounting for about 40% of the global total output. [0003] Macrobrachium rosenbergii, also known as Malaysian prawn and freshwater long-armed prawn, is a large freshwater prawn native to Southeast Asia. It has the advantages of fast growth, wide appetite, good meat nutrition, and short breeding cycle. Since the artificial cultivation of Macrobrachium rosenbergii began in the 1960s, it has developed rapidly, and it is more common to breed this shrimp in Southeast Asian countries and some other regions. my country ...

Problems solved by technology

With the rapid development of the shrimp industry, due to the low technical level of many seedling operators, the seedling technology is still immature, and the nutrient composition of fish and shrimp feed is single, which cannot fully meet the growth needs of fish and shrimp, resulting in uneven quality of seedlings, carrying viruses and Serious problems such as slow growth are emerging one after another, and the survival rate of seedlings is not stable enough, which directly threatens the sustainable development of my country's Macrobrachium rosenbergii industry and seriously affects the economic benefits of farmers
