AI Technical Summary

Technical Problem

In existing technologies, high-density farming of Northeast Forest Frog tadpoles is prone to disease and lacks scientific and reasonable feed formulations, resulting in poor growth and high mortality rates, which affects farming efficiency.

Method used

The feed additives for fully artificially raised Northeast Forest Frogs, including dandelion and Bacillus licheniformis, were added to the basic feed at a mass ratio of (0.02~0.1):1. The basic feed consisted of corn flour, soybean meal, fish meal, mealworm powder, wheat bran, feed yeast powder, and feed vitamin C, and was used for the tadpole stage of Northeast Forest Frogs.

Benefits of technology

It effectively controls digestive diseases, improves intestinal flora, promotes growth and development, increases the survival rate and weight of metamorphosed forest frog larvae, and reduces biological pollution.

Abstract

This invention relates to the field of artificial breeding technology, specifically to a feed additive for the fully artificially bred Northeast Forest Frog and its application. The feed additive includes dandelion and Bacillus licheniformis, wherein the mass ratio of dandelion to Bacillus licheniformis is (0.02~0.1):1. The feed additive provided by this invention can effectively control digestive diseases in forest frog tadpoles, improve intestinal flora, promote weight gain and digestion in forest frog tadpoles, significantly improve the metamorphosis effect of forest frog tadpoles, and increase the survival rate of metamorphosed forest frog larvae.
