Abstract
The invention discloses a parent sturgeon feed and belongs to the field of compound feeds for fishes. The parent sturgeon feed comprises the following raw material components by percentage: 45%-60% offish meal, 10%-20% of bean meal, 8%-12% of peanut meal, 3%-5% of wheat gluten hydrolysate, 3%-5% of earthworm powder, 1%-3% of rice bran oil, 3%-5% of cod oil, 1%-3% of marine microalga extract, 1%-3% of complex mineral substances, 0.2%-0.5% of choline chloride, 2%-6% of beer yeast, 0.1%-0.2% of multiple vitamins for fishes, 1%-3% of fish bone protein peptide powder as well as a small quantity ofshiitake mushroom hydrolysate, bacillus subtilis and milkvetch root extract. The feed disclosed by the invention promotes the gonadal maturation of sturgeons, provides key nutrient substances for embryonic development of filial generations, effectively improves the immunity and disease resistance of parent sturgeons, ensures the normal development of the filial generations, and improves the survival rate of the filial generations.
Description
technical field [0001] The invention relates to the field of compound feed for fish, in particular to the field of compound feed for broodstock of sturgeon, which is a special feed capable of promoting reproductive performance and offspring development of sturgeon. Background technique [0002] Parent fish, also called species fish, is a fish used to reproduce fry, referring to male or female fish that have developed to sexual maturity and are capable of reproduction. Broodstock should be selected from among the best fish, so it is very important to ensure its nutritional level. Like other animals, the reproductive performance of fish is directly regulated by nutrients. Proper nutrient levels in broodstock diets can not only significantly improve egg and sperm quality, but also have long-lasting effects on the growth performance of offspring. Before opening the mouth to ingest exogenous nutrients, fish mainly rely on the yolk sac as their source of nutrition. Therefore, t...
