Penaeus vannamei feed containing chlorella residue

Abstract

The invention discloses a penaeus vannamei feed containing chlorella residue. The penaeus vannamei feed is prepared from the following raw materials in parts by weight: 24.6-29.7 parts of fish meal, 3.0 parts of meat and bone meal, 0.0-19.0 parts of soybean meal, 10.0 parts of peanut meal, 5.0 parts of dried beer yeast, 21.1-24.0 parts of flour, 2.0 parts of cuttlefish meal, 2.0 parts of shrimp shell meal, 2.2 parts of fish oil, 1.4 parts of phospholipid oil, 0.2 part of calcium bicarbonate, 0.2 part of compound vitamin, 0.8 part of compound poly-mineral and 6.0-21.0 parts of chlorella residue. According to the penaeus vannamei feed, the chlorella residue obtained by extracting biodiesel by virtue of an ultrasonic-assisted method is taken as a plant protein source of the penaeus vannamei feed, under the condition that the survival rate and the growth rate of the penaeus vannamei are guaranteed and the cost of a formula is lowered, the use amount of normal soybean meal can be decreased from 19% to 10% when the use amount of the chlorella residue is 11%, the emission amount of nitrogen and phosphorus is reduced, and the growth, the non-specific immunity enzymatic activity, the gill, the hepatopancreas and intestinal canal structure of the penaeus vannamei cannot be influenced negatively.

Description

technical field [0001] The invention relates to the field of aquaculture aquatic animal nutrition and feed science, in particular to a feed for Penaeus vannamei containing chlorella algae dregs. Background technique [0002] Penaeus vannamei belongs to the phylum Arthropoda, Crustacea, Decapod, Penaeidae, and the genus Penaeus. It is a wide temperature, wide salt tropical shrimp. It inhabits the bottom of the water in the natural state, and is active after dusk; it has strong adaptability to the environment, and the high temperature tolerance limit can reach 43.5°C. The shrimp has delicious meat and high unit yield, and is one of the most important breeding objects in my country at present. Studies have shown that Penaeus vannamei has a higher demand for protein, and the optimum protein level of adult shrimp feed is 35%-40%, and the protein requirement of juvenile shrimp feed is higher than that of adult shrimp, about 42%-44%. [0003] The use of high-quality fish meal is...
