Small particle feed special for sturgeon larvae and preparation method thereof

Abstract

The invention discloses a small particle feed special for sturgeon larvae and a preparation method thereof. The small particle feed special for sturgeon larvae comprises the following components in parts by weight: 40-50 parts of degreased fresh fish meal, 15-20 parts of degreased shrimp meal, 10-15 parts of silkworm chrysalis meal, 10-20 parts of blood meal, 20-30 parts of corn meal, 10-20 partsof soybean meal, 5-10 parts of mushroom powder, 3-5 parts of a nutrition enhancing premix, 2-4 parts of an immune enhancing premix and 5-10 parts of a feed forming additive. Through reasonable matching of animal-derived feed components and plant-derived feed components and the nutrient-rich nutrient-enhanced premix, the nutrient requirements of growth and development of sturgeon larvae are comprehensively met; the immunity and resistance of the sturgeon larvae are improved by the immunopotentiation premix; sweet potato starch, gelatin and egg white powder are used as adhesives, and the feed isgreen and healthy; a microbial preparation is also added into the feed, so that the intestinal microecological environment of the sturgeon larvae is improved, and the disease resistance of the larvaeis improved; and the feed is palatable in particle size, and is beneficial to intake, digestion and absorption of sturgeon larvae.

Description

technical field [0001] The invention relates to a sturgeon feed, in particular to a special microparticle feed for juvenile sturgeon larvae and a preparation method thereof. [0002] technical background [0003] Sturgeon grows fast, has delicious meat and high nutritional value, and has good market economic value. At present, wild sturgeon resources are almost exhausted, and almost all sturgeons on the market are artificially raised. Healthy and high-quality fry is the primary guarantee for the high yield of artificially cultured sturgeon. As a special stage in the life history of sturgeon, juvenile sturgeon has the characteristics of small body, immature digestive system, low activity of digestive enzymes, weak activity, weak adaptability to the external environment but rapid growth and so on. Its external morphology, internal structure and physiological metabolism are quite different from juvenile and adult fish. Therefore, the feed for feeding juvenile sturgeon larvae ...

Problems solved by technology

At present, in the breeding process of sturgeons, fish meal and shrimp meal are mostly used as feed for larvae and juveniles. Although these are high-quality baits, due to their insufficient nutrition, it is difficult to meet the growth needs of larvae and juveniles. Therefore, it is necessary to formulate and strengthen the feed for sturgeon larvae to ensure the healthy growth of sturgeon fry
