AI Technical Summary

Technical Problem

Existing feed for earthworms faces technical challenges such as insufficient calcium and phosphorus supply, salt-induced reproduction inhibition, carbon-nitrogen ratio mismatch, uncontrollable raw materials, and reliance on fermentation processes, resulting in insignificant increases in cocoon production and poor cocoon shell quality.

Method used

By employing the synergistic effect of enzymatically hydrolyzed fish protein peptides and Bacillus subtilis, the intrinsic synergistic effect of calcium-phosphorus-humic acid premix, combined with black soldier fly larvae powder, soybean sterol-vitamin E complex, and alfalfa meal, a compound feed is prepared through physical mixing. This avoids high salt addition and fermentation processes, controls the carbon-nitrogen ratio, and provides high calcium, high phosphorus, and reproductive-promoting signals.

Benefits of technology

It significantly increased the cocoon yield, number of eggs per cocoon, and cocoon shell thickness of *Echinochloa crus-galli*, improved the intestinal microecology, ensured the stability and repeatability of feed quality, and avoided the inhibition of high salt and the uncertainty of fermentation.

Abstract

The application discloses a compound feed for promoting cocoon production of broad loach and a preparation method thereof, and relates to the field of agricultural biotechnology.The compound feed comprises enzymolysis fish protein peptide, calcium-phosphorus-humic acid premix, black soldier fly larva dry powder, soybean sterol-vitamin E compound, corn starch, alfalfa powder, bacillus subtilis, saccharomyces cerevisiae and water.The application adopts enzyme hydrolysis and active bacteria cooperation, calcium-phosphorus-humic acid chelation premix and neutralization regulation, significantly improves the cocoon production, single cocoon egg number and cocoon shell thickness of the broad loach, and obviously improves the hatching rate.The application does not add salt and does not depend on a fermentation process, and the formula is standardized, so the application is suitable for population propagation of artificial breeding of the broad loach.
