Fodder for enhancing tachysurus fulvidraco immunity and preparation method thereof

Abstract

The invention relates to the technical field of freshwater fish aquaculture and specifically relates to fodder for enhancing tachysurus fulvidraco immunity and a preparation method thereof. The fodderis prepared by the following steps: S1, deep frying pork fat, grinding, heating until a material temperature is 130 to 150 DEG C and then adding grapefruit leaf powder to perform thermal insulation reaction to obtain a mixture A for standby application; S2, evenly mixing pig bone meal and chicken bone meal, heating until a material temperature is 180 to 200 DEG C and then adding apple peel to perform thermal insulation reaction to obtain a mixture B for standby application; S3, evenly mixing cassava dregs and bagasse to obtain a mixture C for standby application; S4, taking 1 / 2 of the mixtureC, jointly soaking the mixture C into an xanthan gum solution along with the mixture A and the mixture B, stirring the mixtures in a soaking process, taking suspended matter and the remaining mixtureC to granulate, preparing the mixture into particles with the particle size of 1 to 2 mm and then sequentially spraying microbial powder and hydroxyl modified walnut shell flour. The fodder disclosedby the invention has the advantages of good palatability, easiness in being digested, ability to enhance juvenile fish immunity and ability to reduce ammonium nitrogen content.

Description

technical field [0001] The invention relates to the technical field of freshwater fish culture, in particular to a feed for enhancing the immunity of yellow catfish and a preparation method thereof. Background technique [0002] Yellow catfish, Siluriformes, Paliidae, yellow catfish genus, also known as yellow-bone fish, yellow wasp fish, yellow wax ding, yellow catfish bone, etc., is a small economic fish, mainly produced in the Yangtze River and its tributaries, Guangdong and Guangxi There are also a large number of distributions in the Xijiang River Basin. This fish is a medium-to-high-end rare fish that lives in the bottom of the water body. It has delicious meat and high nutritional and medicinal value. The market price is as high as 28-36 yuan / kg. It has great development value, usually 100-200g per individual / tail. In recent years, with the increase of demand at home and abroad, yellow catfish has become an important new species of aquaculture in my country, and so...
