AI Technical Summary

Technical Problem

The prior art is difficult to effectively identify and distinguish individual pigeons, especially within the same breed, which affects individual identification and paternity testing of pigeons.

Method used

A STR fluorescent composite amplification detection system for individual recognition of Chinese pigeons has been developed, including specific primer compositions and kits, which can simultaneously amplify fluorescent labeled composite amplification primer compositions of 20 loci.

Benefits of technology

Highly accurate individual recognition and paternity testing of domestic pigeons can still obtain accurate typing results under low DNA sample size, improving the sensitivity and accuracy of individual recognition.
