Environment-friendly efficient compound feed for cobias and preparation method

Abstract

The invention relates to an environment-friendly efficient compound feed for cobias, which belongs to the field of fish feed and a preparation method thereof. The environment-friendly efficient compound feed for the cobias consists of the following raw materials in percentage by weight: 20 to 30 percent of steam fish meal, 30 to 49 percent of fermented soybean meal, 3 to 6 percent of peanut meal, 3 to 5 percent of beer yeast powder, 2 to 4 percent of sepia paste, 15 to 20 percent of strong flour, 3 to 5 percent of shrimp shell powder, 1 to 2 percent of vegetable oil, 1 to 2 percent of fish oil, 1 to 2 percent of lecithin, 0.5 to 1 percent of composite mineral, 0.3 to 0.5 percent of vitamin complex, 0.5 to 1.5 percent of choline chloride, 0.1 to 0.2 percent of lightyellow sophora root, 0.1 to 0.2 percent of licorice, and 0.1 to 0.2 percent of plantain herb. The environment-friendly efficient compound feed has a good palatability, is easy to ingest, digest and absorb, and reduces feed wastes; by using plant protein sources to replace part of animal protein sources, the emission of nitrogen and phosphorous is reduced, and the feed cost is reduced; the feed coefficient is low and the survival rate is high; the feed is balanced in nutrition and can prevent fatty lever, improve body color and ensure the health of fishes and the freshness of meat quality; and the feed has good stability in water and is difficult to pollute the water quality of a culture water body.

Description

【Technical field】 [0001] The invention belongs to the field of fish feed and a preparation method thereof, and in particular relates to an environment-friendly and high-efficiency compound feed for cobia and a preparation method thereof. 【Background technique】 [0002] Cobia (Rachycentron canadum), belonging to Perciformes, Perciformes, and Cobia family Rachycentridae, is distributed in the Mediterranean Sea, Atlantic Ocean and Indo-Pacific Ocean. It is also distributed in the coastal areas of my country, but the output is small, and it is a warm-water fish in open seas. Because it has many advantages such as fast growth, strong adaptability, few diseases, and easy to catch, and the meat has more thorns, less thorns, delicious taste, and rich nutrition, it is very popular among farmers and consumers. Generally, the price per kilogram is more than 80 yuan, and the economic benefits of breeding are relatively high. Cobia can be cultured in my country's coastal waters. It grow...
