Abstract:Context Several polymorphisms in the melatonin receptor 1A gene (MTNR1A) have been related to reproductive performance in ovine. Aims To investigate the effect of the RsaI and MnlI polymorphisms on ram seminal quality. Methods Eighteen Rasa Aragonesa rams were genotyped for the RsaI (C/C, C/T, T/T) and MnlI (G/G, G/A, A/A) allelic variants of the MTNR1A gene. Individual ejaculates were analysed once a month throughout the whole year. Sperm motility, morphology, membrane integrity, levels of react… Show more
