Problems solved by technology

At present, there are few special feeds for Macrobrachium japonicus on the market. The feeds used in the culture of Macrobrachium japonicus are mostly feeds of Penaeus vannamei or Macrobrachium rosenbergii. Therefore, the nutritional requirements of Macrobrachium japonicus cannot be well met. Shrimp feed intake is low, feed coefficient is high and other deficiencies, resulting in increased breeding costs and reduced benefits

Abstract

The invention relates to a formula of a macrobrachium nipponense feed and a method for preparing a macrobrachium nipponense compound feed from the macrobrachium nipponense feed. The formula of the macrobrachium nipponense feed consists of fish meal, fermented soybean meal, peanut meal, blood powder, yeast, flour, multi-vitamin, multi-mineral, shrimp bran, soybean oil, fish oil, phospholipid oil, squid liver powder and yeast extract. The method for preparing the macrobrachium nipponense compound feed from the macrobrachium nipponense feed comprises the following steps of: weighing according tothe feed formula, stirring and mixing in a stirrer, introducing steam, preparing particles with the particle size of 1 to 1.6mm, dehydrating, cooling, and reducing the temperature of the particles toroom temperature to obtain the macrobrachium nipponense compound feed. The macrobrachium nipponense compound feed is used for feeding macrobrachium nipponense, contributes to meeting the nutritional requirements of the macrobrachium nipponense and improving the food intake of the macrobrachium nipponense, improves feed utilization, increases the yield of the cultured macrobrachium nipponense and reduces culture cost. The macrobrachium nipponense compound feed is applied to the feed used in the culture of the macrobrachium nipponense.

Description

Technical field: [0001] The invention relates to a feed formula, in particular to a feed formula of Macrobrachium japonicus and a method for preparing the compound feed of Macrobrach japonicus. Background technique: [0002] Macrobrachium nipponensis (Macrobrachium nipponensis), commonly known as river prawns and green shrimps, belongs to Crustacea, Decapod order, Swimming suborder, Longarm shrimp family, and Macrobrachium genus. Macrobrachium japonicus is widely distributed in various freshwater waters and some brackish waters in my country. As early as the 1950s, my country carried out the artificial breeding of Macrobrachium japonicus. Because of its fast growth, good stress resistance and strong adaptability, it has become the freshwater freshwater with the most extensive breeding area and the largest output in my country. One of the economical shrimp. [0003] Macrobrachium japonicus has strong attack and defense behaviors. When the breeding environment is not suitable...
