Micropterus salmoides compound feed added with enzymolysis wool powder

Abstract

The invention discloses a micropterus salmoides compound feed added with enzymolysis wool, and relates to a compound feed for aquatic animals. The feed is prepared from the following raw materials in percentage by mass: 10-30% of enzymolysis wool powder, 15-25% of fermented soybean meal, 10-20% of fish meal, 8-15% of rapeseed meal, 5-10% of blood meal, 8% of corn, 5% of wheat, 5% of soybean oil, 3% of fish oil, 1% of vitamin premix, 1% of mineral premix, 0.5% of vitamin C phosphate, 0.5% of choline chloride, 1% of monocalcium phosphate, 0.3-0.5% of lysine, 0.5-0.8% of methionine and 1% of an adhesive. Compared with the prior art, the micropterus salmonides feed has the following advantages: 1, the micropterus salmonides feed is balanced in nutrition and meets the requirements of micropterus salmonides on nutrient substances in the growth process; 2, the feeding effect is not obviously different from that of the whole fish meal compound feed; 3, the fish meal dosage is low, and the production cost of the compound feed is reduced.

Description

Technical Field

[0001] This invention relates to a compound feed for aquatic animals. Background Technology

[0002] California bass is one of my country's important freshwater aquaculture fish, a typical carnivorous species whose formulated feed heavily relies on fishmeal as a protein source. However, the expanding scale of California bass farming and the limited supply of fishmeal have created a sharp contradiction, leading to a continuous increase in the cost of California bass farming. Therefore, there is an urgent need for a production technology that uses other protein raw materials to produce formulated feed for California bass. This protein raw material should have a high protein content, be digestible and usable by California bass, be significantly cheaper than fishmeal, and not affect the growth performance of California bass, or, when used in combination with other substances, not affect the growth performance of California bass.

[0003] In spring and autumn, fattening sheep are sheared to promote fattening and reduce parasite infections. Autumn-sheared wool, known as "second-shear wool," is unsuitable for wool product production and is often disposed of as livestock waste. However, the protein content of second-shear wool is no different from other wool, and processed second-shear wool is an inexpensive source of digestible protein and amino acids. Enzymatically hydrolyzed wool meal can be obtained from second-shear wool through steam explosion and compound enzymatic hydrolysis, making it a high-quality protein feed ingredient. Experiments have shown that adding wool hydrolysate to cat food increases the apparent digestibility of cysteine, while also having a similar effect to dietary fiber. Using enzymatically hydrolyzed wool meal in bass feed, along with taurine or coated methionine, can reduce the amount of fishmeal required without affecting the growth performance of the bass. Summary of the Invention

[0004] This invention aims to provide a formulated feed for California bass with added enzymatically hydrolyzed fish meal, thereby reducing the cost of raising California bass. The formulated feed prepared by this invention is nutritionally balanced, has low production costs, and its feeding effect is not significantly different from that of a whole fish meal formulated feed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention discloses a compound feed for California bass containing enzymatically hydrolyzed wool meal, characterized by: 10-30% enzymatically hydrolyzed wool meal, 15-25% fermented soybean meal, 10-20% fish meal, 8-15% rapeseed meal, 5-10% blood meal, 8% corn, 5% wheat, 5% soybean oil, 3% fish oil, 1% vitamin premix, 1% mineral premix, 0.5% vitamin C phosphate, 0.5% choline chloride, 1% calcium dihydrogen phosphate, 0.3-0.5% lysine, 0.5-0.8% methionine, and 1% binder.
