RD23235Genotyping of rams based on melatonin receptor 1A gene polymorphisms: a tool in sire selection?
Some variants of the melatonin receptor gene affect seasonal reproduction in sheep, but it is not clear how they affect males and their spermatozoa. This study explores the impact of two genetic variants of the melatonin receptor gene on ram seminal quality throughout the year. Results revealed that there is a detrimental effect on seminal quality, more pronounced during the reproductive season, depending on the variant carried, which highlights the potential of genotyping for optimal sire selection in breeding programs.
