Compound feed for adult micropterus salmoides

Abstract

The present invention relates to a compound feed for adult micropterus salmoides. The compound feed comprises the following raw materials in parts by weight: 51-58 parts of dried steamed Peruvian fishmeal, 11-16 parts of high-gluten flour, 1-4 parts of shrimp paste, 4-15 parts of fermented soybean meal, 3-8 parts of mixed oil consisting of fish oil and soybean oil, 3-4.5 parts of brewer's yeasts,0.5-2 parts of minerals, 0.5-1.6 parts of calcium dihydrogen phosphate, 0.1-0.5 part of choline chloride, 1-6 parts of puffed soybeans, 0.2-0.5 part of multi-vitamin, 0.1-0.3 part of vitamin C phosphate and 0.1-0.4 part of methionine; and a mass ratio of the fish oil to the soybean oil in the mixed oil is 1:1. The compound feed for the adult micropterus salmoides is rich in nutrients, good in foodattracting, high in feed conversion rate, excellent in stability in water, strong in disease resistances, and easy to be digested and absorbed by fish body (an apparent digestibility of dry matters is 93.63% or more), and effectively promote rapid and healthy growth of the adult micropterus salmoides.

Description

technical field [0001] The invention relates to the field of compound feed, in particular to a compound feed for adult California perch. Background technique [0002] The scientific name of California perch is largemouth bass, which belongs to the order Perciformes and the family Sunfish. It is one of the main freshwater species in my country. California perch has the advantages of fast growth, low temperature resistance, less thorns, delicious taste, and rich nutrition. It is favored by farmers and consumers and has a huge market prospect. The early breeding of California perch was mainly fed with chilled miscellaneous fish, but the cost of breeding was high, and the water quality was seriously polluted, which seriously affected the safety of aquatic products and the efficiency of breeding. [0003] With the popularization of artificial compound feed, California perch began to use compound feed for breeding, so the research and development of special compound feed for Cali...

Problems solved by technology

The Chinese patent with the application number 201510265383.X discloses a compound feed for adult California perch, which aims to solve the problem of slow growth of California perch by relying on traditional Chinese medicine additives. However, California perch is a typical carnivorous animal with a short digestive tract, and the feed it eats passes through The time of digestive tract is also short. Therefore, it is particularly important whether the compound feed of California perch is easy to be digested and absorbed. However, the compound feed disclosed in the above application number is not conducive to the digestion and absorption of California perch. At the same time, a variety of Chinese herbal medicines are used as additives. It is used for large-scale breeding; in addition, the breeding practice shows that the existing artificial compound feed for California perch still has a series of liver problems such as low protein content and high fat content, which lead to hepatomegaly and fatty liver.

At the same time, studies have shown that there are large differences in the nutritional requirements of California sea bass at different growth stages
