Abstract

The invention provides a slow sinking suspension type shrimp feed and a preparation method thereof and belongs to the technical field of feed, and the slow sinking suspension type shrimp feed is used for solving the problems of high feed coefficient, low feed utilization rate and water quality pollution of the current shrimp feed. The slow sinking suspension type shrimp feed is composed of the following ingredients in weight ratio: 27-33 parts of fish meal, 17.0-20.0 parts of bean pulp, 18.0-25.0 parts of rapeseed dregs, 1.0-1.7 parts of calcium biphosphate, 4.3-5.8 parts of multi-dimensional mineral premix, 1.7-2.1 parts of fish oil, 10.0-13.0 parts of wheat flour, 4.5-6.3 parts of bread flour, 1.3-1.7 parts of phospholipid oil and 1.5-6.3 parts of beer yeast. The feed coefficient of the slow sinking suspension type shrimp feed is 0.9-1.0, and the water stability of the shrimp feed is larger than 12 hours. The shrimp feed is suspended underwater for about 30-200cm underwater or deeper, namely, being located at a semi-suspension state after being scattered in the water, the feed utilization rate is high, and the preparation method is simple, so that the slow sinking suspension type shrimp feed is suitable for breeding shrimps such as oriental prawn, penaeus vannawei and penaeus japonicus.

Description

technical field [0001] The invention belongs to the field of feed technology and relates to a feed for adult shrimp after the juvenile shrimp stage in the aquaculture industry and a preparation method thereof. Background technique [0002] Shrimp is a long-bodied animal that lives in water. It belongs to arthropod crustaceans. It has high food value and can be used as medicinal materials. Therefore, it has a high-efficiency breeding value. With the continuous development of the shrimp farming industry and the improvement of people's living standards, the demand for shrimp is expanding day by day, and the technical requirements for the feed required for adult shrimp farming are also getting higher and higher. In the known technology, the main one of the existing feeds for growing shrimps is hard particles combined with sinking feeds, the feed coefficient is more than 1.1, sinking into the bottom of the shrimp pond, the feed utilization rate is low, and pollutes the water qua...
