Carp feed additive and preparation method thereof

Abstract

The invention provides a carp feed additive and a preparation method thereof. The carp feed additive is prepared from the following raw materials: 6 to 12 parts of herba pteridis multifidae, 6 to 12 parts of rhizoma atractylodis, 6 to 12 parts of honeysuckle flower, 8 to 12 parts of motherwort herb, 5 to 8 parts of mulberry fruit, 8 to 12 parts of herba epimedii, 6 to 8 parts of fructus crataegi, 5 to 8 parts of dried tangerine peel and 15 to 25 parts of compound microbial bacteria. The preparation method comprises the following steps: 1) weighing group A raw materials of traditional Chinese medicine raw materials except compound microorganisms; mixing the group A raw materials and mixing the raw materials into crude powder; adding water which is 15 to 20 times as much as the weight of medicinal materials; extracting at 95 DEG C to 100 DEG C and filtering to obtain medicinal liquid; concentrating the medicinal liquid according to the ratio of 1 to 1 to obtain extract; 2) weighing the compound microbial bacteria and uniformly mixing and stirring the extract of step 1) and the compound microbial bacteria; turning over and fermenting for 2 to 4 days, so as to obtain a fermented product; crushing the fermented product to obtain the carp feed additive. By adopting the feed additive, the anti-pesticide capability of fishes is improved and the proliferation of the fishes is facilitated, so that the survival rate of carps is improved.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a carp feed additive and a preparation method thereof. Background technique [0002] Carp, also known as carp kidnapper and carp, belongs to the Cyprinidae family of Cyprinidae. It is a temperate freshwater fish native to Asia. It likes to live in warm lakes or slow-flowing rivers on the plains.
