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

Abstract

The invention provides a feed for improving the yield of Macrobrachium nipponense 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 blood 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 phosphatide oil, 0.5-1 part of vitamins, 1-2 parts of fish oil, 1-2 parts of shell powder, 2-6 parts of silkworm pupa and 0.5-1 part of organic trace elements premix. 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 aquaculture industry, in particular to a feed and a processing method for increasing the yield of Macrobrachium japonicus. 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] Japanese giant river prawn, also known as river prawn. It is widely distributed in freshwater rivers and lakes in Japan, Southeast Asia, and all over the north and south of my country. It also often occurs in low-salinity estuaries or freshwater waters, and the number is more in shallow water grass lakes. Green shrimp has strong adaptability, wide distribution, and has the characteristics of miscellaneous food habits, fast growth and strong fecundity. With the ...

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 the giant macrobrachium industry in Japan and seriously affects the economic benefits of farmers
