“…The results obtained by the other authors also vary breed to breed. For example while in the Columbia and Dorset sheep breeds the r allele frequencies were found 0.97 and 0.65, respectively [13,30] in the Sarda and Tisdale sheep breeds it found as 0.34 and 0.24, respectively [15,29] . These discordances can be explained in the differences in sampling strategies or nomenclature.…”

“…The MT1 receptor seems to be the only one involved in the regulation of reproductive activity [11,12] . Association studies carried out in the MTNR1A reveal different interesting results for estrus and fertility in the spring [13][14][15] .…”

“…Melatonin can enhance the maturation of oocytes in vitro (Berlinguer et al, 2009;Kang et al, 2009;El-Raey et al, 2011). There was a positive correlation between MTNR1A allele polymorphisms and reproduction in the Sarda sheep breed (Carcangiu et al, 2009(Carcangiu et al, , 2011. Concluding data revealed the positive effect of melatonin treatment on the time of the first conception in ewe lambs and highlighted that +/+ genotype is able to influence reproductive response to melatonin treatment.…”

“…El análisis con el software Genepop arrojó una frecuencia genotípica observada de 68% para el genotipo +/+, 28% para el genotipo +/-y4% para el genotipo -/-(Tabla I), valores son muy similares a los obtenidos en otros trabajos (Carcangiu et al, 2009), observándose diferencias significativas en las frecuencias obtenidas en los genotipos +/+ y -/-en ovejas Araucanas.…”

“…Existen receptores de alta afinidad para la melatonina acoplados a proteínas tipo G llamados MT1 que regulan su efecto sobre los tejidos que tienen relación con las características reproductivas (Dubocovich et al, 2010). El gen que codifica el receptor MT1 es polimórfico en individuos de una misma raza (Messer et al, 1997;Carcangiu et al, 2009). Existen trabajos donde se ha establecido una asociación entre el polimorfismo del receptor MT1 y el desarrollo reproductivo asociado a la duración del anestro en algunas razas ovinas (Chu et al, 2003;Mateescu et al, 2009).…”
