Epinephelus coioicles ecological feed formula and preparation method

Abstract

The invention discloses an epinephelus coioicles ecological feed formula and a preparation method. The epinephelus coioicles ecological feed is prepared from fish meal, tenebrio molitor powder, nereis powder, earthworm powder, silkworm chrysalis meal, shrimp head meal, blood meal, squid visceral powder, beer yeast, bean pulp, soybean phospholipid, alpha-starch, flour, alfalfa meal, moringa powder, macroalgae mixed powder, fish oil, shell mixed powder, dry ginger powder, choline chloride, composite multiple vitamin powder and a phytase preparation. The raw materials are weighed according the proportions, cleaned, dried, smashed and put into a vessel to be stirred to be uniform, granulation is conducted through fluidized bed spray, feed particles are cooled, subpackaged and sealed, and the target product is obtained. According to the epinephelus coioicles ecological feed, feeding is convenient, storing is convenient, the feed quality is high, the nutritional requirement of epinephelus coioicles is met, preparation is dry and thorough, long-term storing is convenient, the feed is not prone to deterioration, active substances in tenebrio molitor, nereides, silkworm chrysalises and fresh ginger can not be subjected to inactivation, the utilization rate of the epinephelus coioicles to the feed is increased, and the growth performance of the epinephelus coioicles is improved.

Description

technical field [0001] The invention relates to the field of fishery feed, in particular to a formula and a preparation method of an ecological feed for grouper. Background technique [0002] The oblique banded grouper (Epinephelus coioicles), commonly known as grouper and blue spot, is one of the suborder Perciformes of the ray-finned fishes. It is distributed in subtropical and tropical seas all over the world. Its meat is plump, fresh and nutritious. , is an important marine cultured fish, and is also one of the most important seawater cage cultured high-grade fish in China. The cultivation of the oblique-banded grouper is mainly concentrated in Asia. The cultivation of the oblique-banded grouper abroad began in the 1960s and in China in the 1970s. It is mainly concentrated in the coastal areas of Fujian, Guangdong, Zhejiang, Hainan, Guangxi, and Taiwan. and other provinces. At present, the culture methods of the oblique grouper include cage culture, pond culture and se...

However, the proportion of amino acids required by fishmeal is the closest to that of aquatic animals. Aquaculture animals prefer to eat the compound feed after adding fishmeal, and adding fishmeal can ensure the rapid and healthy growth of aquaculture animals. Use other protein sources instead of fishmeal to prepare grouper When the compound feed is used, the quality of the feed is often difficult to guarantee. Aquatic animals usually do not like to eat, and in severe cases, it will affect the normal growth and development of the grouper
