Problems solved by technology

[0004] Filter-feeding fish can only be fed powder feed with corresponding crushing fineness, and powder feed has two major disadvantages when put into water: first, the powder feed sinks quickly, silver carp sinks to the bottom before filter feed, and the loss is large and expensive. pollute the pond
Second, the water-soluble rate of powdered feed is high, and some silver carp soluble in water cannot filter feed, resulting in waste of feed
Existing extruded feed particles are too large to be filtered by silver carp, and there are also problems such as water absorption and dissolution during long-term soaking, easy deterioration, and water quality pollution after deterioration. Therefore, it is necessary to provide an extruded feed for silver carp to meet the needs of use

Abstract

The invention relates to the technical field of feed, in particular to expanded feed for silver carp. The expanded feed for the silver carp is prepared from the following raw materials in parts by weight: 60 to 80 parts of premix, 5 to 12 parts of phagostimulant and 8 to 15 parts of traditional Chinese medicinal pellets. The expanded feed for the silver carp has the advantages of low-priced and easily-obtained raw materials, low production cost, abundant and comprehensive nutrition, capability of comprehensively providing all nutrients needed by growth of the silver carp, high feed utilizationrate, good palatability, high safety and no pollution to environment; if the expanded feed is fed for a long term, the immunity of the silver carp can be improved, and the death rate is reduced.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to an extruded feed for silver carp. Background technique [0002] Silver carp, also known as silver carp and silver carp, belongs to Cypriniformes, Cyprinidae, with a flat side, slightly taller, spindle-shaped body, blue-gray back, white sides and abdomen. It is one of the four famous big family fishes and is typical filter-feeding fish. [0003] Silver carp is sweet in taste, flat in nature, non-toxic, and its meat is fresh and tender, rich in nutrition. It is one of the excellent fish species suitable for breeding. It is the main freshwater cultured fish in my country. Freshwater fish have the characteristics of fast growth, less disease and high yield, and are mostly mixed with grass carp and carp. [0004] Filter-feeding fish can only be fed powder feed with corresponding crushing fineness, and powder feed has two major disadvantages when put into water: first, the powder feed si...
