Special compound feed for largemouth bass and preparation method of special compound feed

Abstract

The invention discloses a special compound feed for a largemouth bass. The special compound feed comprises the following components in parts by weight: 6-10 parts of wheat, 9-12 parts of flour, 18-22 parts of soybean meal, 3-8 parts of corn gluten meal flour, 28-32 parts of fish meal, 10-14 parts of meat and bone meal, 3-7 parts of hydrolyzed fish protein, 4-6 parts of fish oil, 1-2 parts of soybean soil, 0.9 part of a complex vitamin, 0.5 part of compound mineral salt, 0.5-0.8 part of choline chloride, 1-1.2 parts of monocalcium phosphate, 0.15-0.2 part of vitamin C, 0.015-0.02 part of vitamin E, 0.1-0.2 part of methionine, 0.1-0.2 part of lysine, 0.1-0.15 part of inositol, 0.1-0.3 part of edible salt, 0.05-0.1 part of an antioxidant and 0.06-0.1 part of a mildew preventive agent. The special feed disclosed by the invention has the advantages of overcoming the defect of slow later-period growth of the largemouth basses and effectively reducing mutual killing of the black basses.

Description

technical field [0001] The invention relates to the field of feed, more specifically, to a special compound feed for largemouth bass and a preparation method thereof. Background technique [0002] Largemouth bass (Micropterus salmoides), taxonomically belongs to the genus Perciformae Perciformae. It is also known as California perch because it is native to California, the United States. In 1983, largemouth bass was introduced from Taiwan Province to the mainland by Guangzhou Province. With the advantages of fast speed, wide temperature adaptability, strong disease resistance and easy fishing, largemouth bass has become an important economic fish in freshwater aquaculture in my country. [0003] At present, although largemouth bass farming in my country has achieved intensive and large-scale farming, because of its special feeding habits, largemouth bass fish bodies will kill each other and prey on each other in the absence of sufficient palatable bait. So far, there is sti...

Problems solved by technology

However, the availability of chilled trash fish is seasonal, not year-round, and the quality of chilled trash fish is unstable, and storage is more difficult. In addition, the feed factor of chilled trash fish is higher, and it is more likely to pollute the water body environment, and even cause the spread of fish diseases, thus posing a great hidden danger to food safety

[0004] Compared with chilled food, compound feed is more environmentally friendly and safer. Since the 1990s, domestic scientific research institutions and feed companies have continued to develop research on compound feed for largemouth bass, but so far there has been no breakthrough. Although Commercial compound feeds have been put on the market, but it was found in the breeding process that when the largemouth bass fed with compound feed grows to 150-200g, symptoms such as anorexia and slow growth will appear, and it has become the current largemouth bass. The bottleneck problem of promoting artificial compound feed in the breeding process needs to be overcome urgently
