The main environmental factor that affects the regulation of reproductive seasonality is photoperiod through its effects on melatonin secretion. The melatonin receptor MTRN1A appears to be involved in regulating the reproductive seasonality and milk production in the period. The aim of this study was to identify polymorphisms in the MTRN1A gene and their possible associations with milk, fat and protein productions, fat and protein percentages, age at first calving, and first calving interval in buffaloes. Three genotypes (CC, CT, and TT) were identified by PCR-RFLP, and there was a significant association with protein percentage (P < 0.0001). Further studies are necessary to better understand the influence of melatonin gene and their receptors in the productive functions of buffaloes.
影响繁殖季节性调节的主要环境因素是光周期，它通过影响褪黑素分泌来起作用。褪黑素受体MTRN1A似乎参与调节该时期的繁殖季节性和产奶量。本研究的目的是鉴定MTRN1A基因中的多态性及其与水牛产奶量、乳脂和乳蛋白产量、乳脂和乳蛋白百分比、初产年龄以及首次产犊间隔的可能关联。通过PCR-RFLP鉴定出三种基因型（CC、CT和TT），并且与乳蛋白百分比存在显著关联（P < 0.0001）。有必要进行进一步研究，以更好地了解褪黑素基因及其受体对水牛生产性能的影响。
