Omnivorous fish feed and preparation method thereof

Abstract

The present invention discloses an omnivorous fish feed, which comprises one or a plurality of materials selected from the following components: fish meal, wheat bran, corn germ meaL-so1, wheat-middlings, rapeseed meal, peanut meal, a composite vitamin premix, a traditional Chinese medicine combination additive, a mineral premix, and a feed binder, wherein the traditional Chinese medicine combination additive further comprises the following raw material drugs: indigowoad root, glossy privet fruit, tuckahoe, baikal skullcap root, weeping forsythia fruit, patrinia, szechwan lovage rhizome, heartleaf houttuynia herb, suberect spatholobus stem, salvia miltiorrhiza, prepared rhizome of rehmannia, dangshen, mongolian milkvetch root, oldenlandia and cortex moutan, the feed binder further comprises high strength flour and starch, a weight part ratio of the high strength flour to the starch is 5-6:4-5. According to the present invention, the Chinese herbals are adopted to prevent and treat fish diseases, such that requirements of pollution-free aquaculture development and green aquatic product production are completely met; the omnivorous fish feed of the present invention has characteristics of high water resistance and low scatter ratio; with the omnivorous fish feed of the present invention, absorption growth of omnivorous fishes and especially tiny fishes are easily achieved, fish taste is improved, outbreak of fish diseases can be significantly reduced, immunity of omnivorous fishes can be improved, safe and efficient farming can be ensured, and good economic benefits and social benefits are provided.

Description

technical field [0001] The invention relates to a fish feed produced by using animals and plants as raw materials and a preparation method thereof, in particular to an omnivorous fish feed and a preparation method thereof. Background technique [0002] Omnivorous fish are represented by carp and rainbow trout. Carp is a benthic omnivorous fish that eats both meat and vegetables. Carp has a wide range of baits, well-developed rostral bones, and often feeds on mud. Carp is also a low-level temperature-changing animal, and its body temperature changes with the change of water temperature. It does not need to consume energy to maintain a constant body temperature, so the total amount of bait and food it needs is not large. At the same time, carp, like most freshwater fish, is a stomachless fish species with a thin and short intestinal tract and a fast metabolism, so the eating habit is to eat less and frequently. The digestive function of carp is greatly related to the water ...

Problems solved by technology

[0006] The research on extrusion technology in my country is mainly concentrated in the field of food processing and the pretreatment of feed raw materials. The production of extruded fish feed is still in its infancy. On the one hand, due to the relatively expensive extrusion machinery and the high maintenance cost, resulting in The production cost of fish feed increases, which leads to the increase of fish farming cost; on the other hand, due to the existence of various controllable factors and interference factors in the extrusion process, changes in these factors have a greater impact on product quality

If various factors cannot be effectively controlled in a timely manner during the production process, it will be difficult to ensure the stability of the production process and the quality of the final product
