Abstract:

The meat quality traits of livestock and poultry have become a research hotspot in the fields of food science and animal breeding due to the rising market demand for high-quality livestock and poultry meat. Meat quality traits are affected by multiple signaling pathways and transcription factors. The thorough understanding of the candidate genes that regulate meat quality traits is important for improving meat quality and breeding superior livestock and poultry breeds. This paper reviews the research progress in candidate genes closely related to intramuscular fat (IMF) content, inosine monophosphate (IMP) content, tenderness, pH value, color, and other meat quality traits, in hoping to provide theoretical guidance for investigations on livestock and poultry breed improvement and molecular marker assisted breeding.

Key words: meat quality, candidate gene, intramuscular fat, inosine monophosphate, tenderness
