Compound feed for improving intestinal health of largemouth basses and preparation method and application thereof

Abstract

The invention relates to a compound feed for improving the intestinal health of largemouth basses and a preparation method and application thereof. The compound feed for improving the intestinal health of the largemouth basses comprises the following components in parts by weight: 10-20 parts of fishmeal, 5-10 parts of chicken powder, 10-20 parts of hydrolyzed fish protein powder, 10-15 parts of pork powder, 2-5 parts of spray-dried blood cells, 1-5 parts of silkworm chrysalis meal, 3-5 parts of corn protein powder, 4-6 parts of soybean meal, 15-20 parts of flour, 1-2 parts of fish oil, 3-5 parts of soybean oil, 1-3 parts of soybean phospholipid oil, 3-5 parts of yeast enzymatic hydrolysate, 0.01-0.1 part of glyceryl tributyrate, 1-2 parts of stachyose, 1-2 parts of xylan, 2.5-3 parts of calcium dihydrogen phosphate, 1-2 parts of choline chloride and 1-2 parts of freshwater fish premix. The compound feed has the beneficial effects that (1) a synergistic effect is achieved, and the intestinal health of the largemouth basses can be effectively improved; and (2) the compound feed of the present invention is balanced in nutrition, the largemouth basses grow rapidly after being fed withthe compound feed, and the disease resistance is strong.

Description

technical field [0001] The invention relates to a compound feed for largemouth bass, in particular to a compound feed for improving intestinal health of largemouth bass, a preparation method and application thereof. Background technique [0002] Largemouth bass, also known as California perch, belongs to Perciformes, Perciformes, Sunfishidae, and Black Perch in taxonomy. It is native to the Mississippi River system in California, USA. It is a delicious meat, strong disease resistance, It is a rare carnivorous fish that grows quickly, is easy to catch, and has a wide temperature adaptability, and is deeply loved by consumers. [0003] Since the introduction of largemouth bass into my country, the scale of largemouth bass cultivation has continued to expand in recent years. In 2016, its production has exceeded 370,000 tons. The breeding areas are all over the country. Among them, Guangdong Province has the largest breeding production, reaching 234,700 tons. At present, largem...

AI Technical Summary

Problems solved by technology

At present, largemouth bass farming still mainly relies on chilled miscellaneous fish. However, there are problems such as unstable source of chilled miscellaneous fish, easy to carry pathogenic microorganisms, and pollute the environment. Therefore, the development of artificial compound feed that meets the growth needs of largemouth bass needs to be solved urgently

[0004] However, the compound feeds currently on the market are likely to damage the intestinal health of largemouth bass, resulting in reduced food intake, slow growth, and even large-scale death of largemouth bass in severe cases.
