Giant freshwater prawn feed test method

Abstract

The invention relates to a giant freshwater prawn feed test method. The method includes the following steps: 1) selecting giant freshwater prawns with the initial body mass of 1.36g +- 0.06g, and theinitial body length of 3.95cm +- 0.06cm; 2) feed test: adopting soybean meal, fishmeal, peanut meal and meat powder as a protein source to prepare a base feed according to the nutritional requirementof the giant freshwater prawns, adopting the base feed as a control group; replacing 0%, 9.15%, 18.25% and 27.35% of fishmeal in the base feed with 0%, 5%, 10% and 15% of corn gluten meal in a test feed; 3) feeding management; 4) determination of 4.1) growth performance indicators; 4.2) nutrient indicators; 5) statistical analysis. According to the method, the feasibility of application of the corn gluten meal in the feed of the giant freshwater prawns is achieved, and a basis for the application of the corn gluten meal in the feed of the giant freshwater prawns is provided.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a feed test method for Macrobrachium rosenbergii. Background technique [0002] Macrobrachium rosenbergii (Macrobrachium rosenbergii), also known as white-legged prawns, Malaysian prawns, money prawns, Penaeus prawns, etc., is known as the king of freshwater shrimps. Because of its thin shell and fat body, fresh and tender meat, rich nutrition, wide appetite, fast growth, easy domestication, and short breeding cycle, it has become one of the main varieties of freshwater shrimp farming in the world. The application of feed is a key link in aquaculture. In recent years, the cost of compound feed for Macrobrachium rosenbergii has increased significantly due to the soaring price of fish meal and other feed raw materials. Without affecting growth, reducing the level of fishmeal in feed is the key to reducing the price of feed. Therefore, seeking cheap protein sources to replace fishmeal in fe...
