Prochilodus scrofa advanced fry mixed feed and preparation method thereof

Abstract

The invention relates to prochilodus scrofa advanced fry mixed feed, and further relates to a preparation method of the prochilodus scrofa advanced fry mixed feed. The prochilodus scrofa advanced fry mixed feed is prepared from the following components in parts by weight: 20 to 30 parts of ulex europaeus powder, 4 to 13 parts of cicada powder, 6 to 15 parts of alfalfa seed powder, 5 to 14 parts of thin sheets of bean curd, 4 to 13 parts of sweet photo leaves, 6 to 14 parts of shepherdspurse herb, 5 to 16 parts of water celery, 4 to 14 parts of osmunda cinnamomea, 5 to 14 parts of arrowhead, 6 to 16 parts of clam powder, 3 to 9 parts of plantain herb, 2 to 9 parts of endothelium corneum gigeriae galli, 3 to 10 parts of fish oil, 1 to 6 parts of honey, 2 to 6 parts of olive oil, and 1 to 4 parts of compound vitamin. The prochilodus scrofa advanced fry mixed feed is provided according to an energy metabolism mode and nutritional requirement of prochilodus scrofa advanced fries, can completely replace fish meal, after the prochilodus scrofa advanced fry mixed feed is fed to the prochilodus scrofa advanced fries, the survival rate of the prochilodus scrofa advanced fries is high, the feed coefficient is low, and the specific growth rate is high.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed for juvenile South American herring; the invention also relates to a preparation method of the compound feed for juvenile South American herring. Background technique [0002] South American herring has a streamlined body; brightly colored with silvery flashes on the sides and dark blue metallic back; adults are 20-38 cm (8-15 inches) long. It is one of the most abundant fishes in the world. The body is elongated and laterally compressed, and the body length is generally 25-35 cm. mouth port. Eyes large, with fat eyelids. The premaxilla is small, the maxilla is rectangular, and there are 2 auxiliary maxillae. There are fine teeth on the mandible, vomer and tongue, but no teeth on the maxilla and palatine. The gill membrane is not connected with the isthmus, the body is covered with thin round scales, the abdomen is blunt and round, and the rib scales are smaller. [0003] At p...

Problems solved by technology

Fishmeal is the closest to the amino acid ratio required by aquatic animals. Adding fishmeal can ensure the rapid and healthy growth of aquaculture animals. When other protein sources are used instead of fishmeal to prepare compound feed for South American herring juveniles, the quality of the feed is often difficult to guarantee. Affects normal growth and development of South American herring juveniles

However, with the rapid development of the aquaculture industry, the demand for aquafeeds has increased rapidly, and the problem of the shortage of domestic fishmeal resources has become increasingly prominent. During the growth process, due to lack of resistance, various fish diseases will occur, which will affect the survival rate of South American herring. Growth and disease-resistant South American herring juvenile compound feed is an urgent problem in the current South American herring farming industry
