Perfect compound feed with low nitrogen and phosphorus emissions for feeding culter alburnus and preparation method of perfect compound

Abstract

The invention discloses a perfect compound feed with low nitrogen and phosphorus emissions for feeding culter alburnus and a preparation method of the perfect compound feed. The perfect compound feed comprises the following raw materials: fish meal, puffed bean pulp, puffed beans, shrimp shell meal, DDGS, vegetable cake, cottonseed meal, wheat, monocalcium phosphate, multi-vitamin premix, polymineral premix, fish oil, lard oil, vegetable oil, compound amino acid, granulesten, glycine betaine, choline chloride, phytase, purple perilla and the like. The prepared perfect compound feed has the characteristics that the protein utilization efficiency is high; the decomposition of protein into amino acid for energy metabolism is alleviated by amino acid balance; the energy utilization of lipid is improved by adjusting lipid metabolism and hepatoprotective effect; the utilization rate of phosphorus in the feed is high; phytate phosphorus is degraded by mainly selecting special phytase and is changed into effective phosphorus for use; the properties of the feed are ensured by a production process of puffing and pelletizing at high temperature and spraying at low temperature; the feed is reasonable in formula; the processing process of the feed is scientific; the nitrogen and phosphorus emissions are reduced; the requirements on healthful aquaculture of the culter alburnus can be met.

Description

technical field [0001] The invention relates to a preparation method of animal feed, in particular to a low-nitrogen and phosphorus-emission full-price compound feed used for raising Cichlid carp and a preparation method thereof. Background technique [0002] With the rapid development of aquaculture in my country, the aquaculture production is constantly changing from the traditional extensive farming model to the intensive intensive farming model. At this stage, the majority of farmers have gradually realized the benefits of using compound feed, and began to gradually adopt compound feed for farming. In order to ensure the high efficiency and ecological health of breeding, the development of compound feed is in full swing. [0003] Protein is the main nutrient for animal growth, especially carnivorous fish have poor utilization of sugar, and some protein is consumed as energy. However, if a large amount of protein is decomposed into amino acids for energy metabolism, a l...

Problems solved by technology

Due to the reduction of the resources of wild Clamella in natural water bodies, artificial breeding has developed rapidly. However, the compound feed for this fish is mainly borrowed from other fish. The bait coefficient is large and it is easy to cause water pollution.
