Compound feed for the polyculture of Litopenaeus vannamei and Trachinotus ovatus and a preparation method thereof

Abstract

The present invention provides compound feed for the polyculture of Litopenaeus vannamei and Trachinotus ovatus and a preparation method thereof. The compound feed is characterized by comprising the following ingredients in parts by weight: 15-25 parts of fish meal, 5-10 parts of meat and bone meal, 1-5 parts of maggot powder, 15-25 parts of soybean meal, 5-10 parts of peanut bran, 1-5 parts of soybean protein concentrate, 1-5 parts of cottonseed meal, 1-5 parts of corn gluten meal, 1-3 parts of molasses yeast, 1-3 parts of corn DDGS, 1-3 parts of squid paste, 1-3 parts of shrimp shell powder, 20-25 parts of high-gluten flour, 1-2 parts of sea fish oil, 1-2 parts of soybean oil, 1-2 parts of soy lecithin, 0.5-1 parts of calcium dihydrogen phosphate, 0.1-0.3 parts of choline chloride, 0.1-0.3 parts of cholesterol, 0.05-0.1 parts of L-ascorbate-2-monophosphate, 0.1-0.3 parts of coated lysine, 0.1-0.3 parts of coated methionine, 0.1-0.3 parts of Bacillus subtilis, 0.1-0.3 parts of mannan, 0.1-0.5 parts of complex vitamins, 0.1-0.5 parts of complex mineral salts. Experiments show that the compound feed for the polyculture of Litopenaeus vannamei and Trachinotus ovatus of the present invention can effectively meet the comprehensive nutrient needs of both Litopenaeus vannamei and Trachinotus ovatus, significantly improves the effective utilization of the feed, and has a relatively low food coefficient.

Description

technical field [0001] The invention relates to a feed for aquatic animals, in particular to a compound feed for mixed cultivation of Litopenaeus vannamei and pomfret ovata and a preparation method thereof. Background technique [0002] Litopenaeus vannamei is native to America. According to statistics, the output of Litopenaeus vannamei has accounted for more than 90% of the total output of prawns in my country in recent years. With the rapid development of its breeding industry, relevant research is also in full swing. Nearly 100 relevant Chinese patent applications and scientific research achievements have been published, such as Chinese patent application CN101099541A low-salinity culture Litopenaeus vannamei additive premix, Chinese patent application CN1923032A humic acid Litopenaeus vannamei compound feed, etc. [0003] Oval pomfret (Trachinotus ovatus), also known as golden pomfret, yellow wax pomfret, etc., is a fish of the order Perciformes, family Trevalidae, an...

AI Technical Summary

Problems solved by technology

Among them, the polyculture model of Litopenaeus vannamei and Pompano ovata has become one of the main choices for the transformation of single intensive culture, but at the same time, the research on this polyculture model is relatively weak

There are fewer nutritional studies on its special feed. Generally, everyone uses compound feed for Litopenaeus vannamei or extruded fish feed for feeding. The effective utilization rate of the feed is low, and it cannot fully meet the needs of Litopenaeus vannamei and pomfret. Trevally has a comprehensive demand for nutrition, and the operation is too cumbersome
