Breed identification is fundamental to livestock conservation and plays a vital role in genetic resource management， breed purity assessment， breeding strategy implementation， product traceability， supply chain optimization， and ensuring food and biosafety. This review summarizes both traditional and modern methods for breed identification of common livestock and poultry （pig， cattle， sheep， dog， chicken）， and systematically reviews recent advances in machine learning-based breed identification research.Traditional methods， such as morphological assessment and physicochemical indicator analysis in animals，are increasingly inadequate for large-scale breed identification due to their limited accuracy，operational complexity，and time-consuming nature. With advancements in intelligent animal husbandry and high-throughput omics technologies， machine learning-based approaches have gained wide application. This paper reviews major achievements in breed identification using machine learning， analyzes the strengths and limitations of various algorithms， and highlights challenges in practical use. It offers insights for future development and supports molecular breeding and precision livestock management.
