Preparation method of compound type fish feed

Abstract

The invention relates to the field of fishery breeding and in particular relates to a preparation method of fish feed. According to the preparation method of the compound type fish feed, the compound type fish feed is prepared from a main material, a compound additive, a compound Chinese herbal medicine and a feed binding agent and is processed according to the following steps: mixing and grinding the main material and the compound additive and uniformly mixing to obtain a mixture; adding water into the compound Chinese herbal medicine and decocting; filtering out medicine dreg and collecting medicine liquid; adding the mixture and the feed binding agent into the medicine liquid; after uniformly stirring, concentrating to obtain powder feed; pelleting and molding the powder feed into pellet feed by utilizing a feed machine. When various types of raw materials are mixed through utilizing properties of Chinese herbal medicines, original dry-powder solid state mixing is changed into solid-liquid mixing of dry powder and the medicine liquid of the Chinese herbal medicines; after the raw materials are dissolved into the medicine liquid of the Chinese herbal medicines, the mixing is more uniform; when final mixed liquid is heated and concentrated into the dry powder, the sterilization and disinfection effects are also realized; the feed with uniform components is more beneficial to the absorption of fishes, the feed coefficient can be effectively reduced and the culturing cost is reduced.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a method for preparing fish feed. Background technique [0002] The quality of feed is very important to fish farming. Usually, feed accounts for 60-75% of the cost of farming and has the greatest impact on the efficiency of farming. Feed quality is mainly reflected in three aspects: feed coefficient, price and fish survival rate. Because the characteristics and needs of each fish are different, the feed required by different fish will be different; most of the existing fish feeds are simply mixed and pelletized or directly powdered feed, powder feed is easy to dissolve in water, and the utilization rate is low. Pellet molding will cause uneven mixing, which affects the fish's absorption of feed and nutritional balance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compound fish feed preparation method that uses the ...
