A kind of duck-billed sturgeon feed that reduces the incidence of disease

Abstract

A duck-billed sturgeon feed with reduced morbidity provided by the invention comprises the following components in parts by weight: 40-60 parts of fish meal, 20-40 parts of freshwater shrimp meal, 10-30 parts of pig liver powder, 10-20 parts of kelp powder, 60-80 parts of soybean meal, 20-40 parts of sorghum, 10-20 parts of soybean flour, 10-20 parts of barley flour, 20-30 parts of cotton meal, 10-20 parts of rapeseed meal, 5-15 parts of bran, clam worm 5-15 parts of flour, 10-20 parts of wheat flour, 5-15 parts of alfalfa powder, 20-30 parts of lecithin, 4-6 parts of seaweed powder, 4-6 parts of medical stone powder, 5-15 parts of vegetable oil, core additives 4-6 parts; every 100 parts of the core additive is made of the following components by weight: 20-30 parts of garlic, 20-30 parts of onion, 10-20 parts of dandelion, 10-20 parts of calamus, 5-15 parts of capillary parts, 5-15 parts of Dendrobium. The duck-billed sturgeon provided by the invention can not only provide the basic nutrients of the duck-billed sturgeon and ensure the growth efficiency of the duck-billed sturgeon, but also improve the meat quality of the duck-billed sturgeon by optimizing the feed formula and adding core additives, with high safety, wide source of raw materials and low price.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a duckbill sturgeon feed with reduced disease incidence. Background technique [0002] Duckbill sturgeon, scientific name American sturgeon. It mainly feeds on earthworms, shrimps and plankton. It is named because of its unique shape, long and flat snout, like a duckbill and paddle-like shape. The duck-billed sturgeon (Acipenser acipenser) is native to the Mississippi River Basin in the United States. It is a rare sturgeon that has lived on the earth 300 million years ago (that is, the dinosaur period). It is the only two species of Acipenser in the world. one of the species. It belongs to the family Acipenseridae of the order Acipenseridae, together with the Chinese sturgeon and the white sturgeon in the waters of the Yangtze River, and is one of the best fish among fishes.

AI Technical Summary

Problems solved by technology

[0003] At present, there are several major problems in the breeding technology of duckbill sturgeon: First, in the environment of still water ponds in most of the breeding industry in our country, high-density breeding causes a large amount of aquatic animal excrement, residual bait, disinfectants, etc. A large amount of harmful substances are released, which increases the density of aquaculture, degrades the water environment, and aggravates aquaculture diseases. Many diseases have seriously threatened the efficiency of aquaculture.

However, the loss of feed in water and the accumulation of excreta have become the main pollution sources of water bodies, resulting in deterioration of water quality, large-scale reproduction of pathogens, decreased survival rate, increased dosage of medicines, frequent water changes, and increased breeding costs.
