Feeds for feeding Takifugu obscurus and preparation method thereof

Abstract

The invention relates to feeds for feeding Takifugu obscurus and a preparation method thereof, belonging to the technical field of animal feeds. The feeds are obtained by the following steps: after being mixed with choline chloride, soybean meal or peanut meal is then mixed with combination of corn gluten meal or rapeseed meal and cottonseed meal to obtain a mixture A; compound additive is mixed with starch to obtain a mixture B; the mixture A is mixed with the mixture B to obtain a mixture C; flour, chicken powders or meat and bone meal is mixed with fish meal to obtain a mixture D; and the mixture C is mixed with the mixture D to obtain a mixture E; and the mixture E is prepared to be granules with the size similar to soybean, and the granules are mixed with fish oil to obtain the feeds.The invention has the advantages that the feeds save fish meal resources, reduce discharge of nitrogen phosphorus, alleviate the pressure of fish meal resource shortage in a market, enhance the yieldof the Takifugu obscurus, improve the utilization ratio of the feeds, cause various nutritional components to be uniform, and alleviate the permeation of water-soluble nutritional components into water.

Description

Technical field: [0001] The invention belongs to the technical field of animal feed, and in particular relates to a feed for feeding puffer puffer obscurus and a preparation method thereof. Background technique: [0002] Fugu obscurus (Takifugu obscurus), commonly known as puffer fish, is a potential economic fish species with delicious meat, high edible rate and rich nutrition, and tetrodotoxin can be extracted from the liver and ovary for the treatment of neuralgia , convulsions, nocturia, etc., have extremely high edible and medicinal value, so it has the value of development. [0003] Fugu obscurus has a large output, occupies a certain proportion in the entire Yangtze River fishery, and has a certain economic value. However, due to the influence of many factors such as overfishing of broodstock and water pollution, the resources of Fugu obscurus in the Yangtze River tend to be exhausted. Therefore, artificial breeding of Fugu obscurus is an inevitable choice, and feed ...

Problems solved by technology

[0004] Because traditional fugu obscurus does not have mature feed, it is usually fed with the feed of eel, and the feed formula that has been disclosed, such as Shen Meifang, is equal to the feed described in "Research on the Effect of Several Feed Additives Feeding Puffer obscura" in 1999 The formula is 56% white fish meal, 22% starch, 5% gluten, 5% yeast, 3% soybean meal, 1.5% fish oil, 7.5% trace elements, vitamins and others; another example is Wu Beiqi and Shen Meifang , Yin Yue, and Wu Guanghong described in "Aquaculture" 2000, No. 01 "A Preliminary Study on the Apparent Digestibility of Fugu obscura to Compound Feed", in which white fish meal accounted for 58%, α-starch accounted for 22%, and yeast Accounting for 5%, soybean meal 5%, fish oil 2%, additives and others 8%. Currently, fishmeal accounts for a large proportion in the published feed formula, and the use of a large amount of fishmeal in feed is the main reason for the shortage of fishmeal resources. , and fishmeal, a kind of high-protein feed material that uses one or more kinds of fish as raw material, after deoiling, dehydrating, and crushing, has a low output in China. The fishmeal industry in China started late and is mostly small Production, the output is low, so it mostly depends on imports. At the end of the 20th century, China imported about 700,000 tons of fishmeal every year; a large amount of fishmeal was used in feed, which also caused environmental pollution due to high phosphorus and nitrogen emissions.
