AI Technical Summary

Technical Problem

Existing methods for processing fish affected by alimentary-toxic paroxysmal myoglobinuria (ATPM) fail to effectively neutralize the toxin, leading to decreased fish productivity and economic losses, and the resulting fish meal is unsafe for animal consumption.

Method used

A high-temperature drying process at 180-185°C for 25-30 minutes followed by 150-155°C for 200-210 minutes, combined with mechanical stirring and grinding, is applied to grind and dry fish raw material to neutralize the ATPM toxin, producing a safe fish meal for animal feed.

Benefits of technology

The method effectively neutralizes the ATPM toxin, allowing the production of a safe fish meal that can be used as a feed supplement without causing physiological changes in animals, thus restoring fish productivity and improving water body health.

Abstract

FIELD: biotechnology; veterinary medicine.SUBSTANCE: used in the production of fish feed products for feeding animals and birds. Toxic fish is chopped into pieces no more than 3 cm, then ground in a mill, the resulting chopped raw material is placed in an even layer on a baking sheet and subjected to the drying process in a drying oven at a temperature of 180-185 °C within 25-30 minutes. Then at a temperature of 150-155 °C for 200-210 minutes, with periodic stirring. The resulting fish meal is further used as a feed additive for animals and poultry.EFFECT: neutralization of toxins in fish.1 cl, 2 ex
