The aim of the research was to describe the polymorphisms of the MTNR1A gene in three Slovenian sheep breeds, and determine whether these polymorphisms affect reproductive performance. A total of 100 Bovška, 110 Istrian Pramenka, and 108 Jezersko-Solčavska ewes, were used. The rams were placed with the ewes on 10 October (Bovška), and 20 September (Istrian Pramenka). At each farm, the lambing date and number of newborn lambs were recorded to evaluate the fertility rate, number of days from ram placement with ewes to lambing (DRIL), and litter size. The Jezersko-Solčavska rams were maintained with the ewes of the flock throughout the year and data related to lambing during the entire year were recorded. The DNA sequences indicated there were eight nucleotide variations and that in the position g.17355358 was always associated with that in the position g.17355452. For the Bovška breed, there was an association between the G/G genotype in the position g.17355452, and relatively greater fertility (P < 0.05) and a shorter DIRL (P < 0.05). For the Istrian Pramenka breed, the T/T genotype in the position g.17355458 was positively associated with a greater fertility (P < 0.05) and shorter DRIL (P < 0.05). For the Jezersko-Solčavska breed, ewes with the G/G genotype in the position g.17355452 lambed more when there was a decreasing photoperiod whereas the ewes with the A/A genotype lambed more (P < 0.05) during the period when there were increasing photoperiods. The different polymorphisms studied were associated with reproductive performance in the three Slovenian breeds.

三种斯洛文尼亚绵羊品种的MTNR1A基因具有不同等位基因的生殖性能。

该研究的目的是描述三个斯洛文尼亚绵羊品种中MTNR1A基因的多态性,并确定这些多态性是否影响生殖性能。总共使用了100头Bovška,110头Istrian Pramenka和108头Jezersko-Solčavska母羊。在10月10日(Bovška)和9月20日(Istrian Pramenka)将公羊和母羊放在一起。在每个农场,记录产羔的日期和新生羔羊的数量,以评估受精率,从母羊放置母羊到产羔的天数(DRIL)以及产仔数。全年对Jezersko-Solčavska母羊进行母羊饲养,并记录了全年与羔羊有关的数据。指示的DNA序列有八个核苷酸变异,而在位置g。17355358始终与g.17355452中的位置相关联。对于Bovška品种,在g.17355452位置的G / G基因型与相对较高的生育力(P <0.05)和较短的DIRL(P <0.05)之间存在关联。对于伊斯特拉普拉门卡(Istrian Pramenka)品种,位于g.17355458的T / T基因型与较高的生育力(P <0.05)和较短的DRIL(P <0.05)正相关。对于Jezersko-Solčavska品种,在光周期降低的情况下,g / G基因型在17355452位的母羊产羔更多,而A / A基因型的母羊在更多的时期产羔更多(P <0.05)。增加光周期。研究的不同多态性与斯洛文尼亚三个品种的繁殖性能有关。g.17355452位置的G / G基因型与相对较高的生育力(P <0.05)和较短的DIRL(P <0.05)之间存在关联。对于伊斯特拉普拉门卡(Istrian Pramenka)品种,位于g.17355458的T / T基因型与较高的生育力(P <0.05)和较短的DRIL(P <0.05)正相关。对于Jezersko-Solčavska品种,在光周期降低的情况下,g / G基因型在17355452位的母羊产羔更多,而A / A基因型的母羊在更多的时期产羔更多(P <0.05)。增加光周期。研究的不同多态性与斯洛文尼亚三个品种的繁殖性能有关。g.17355452位置的G / G基因型与相对较高的生育力(P <0.05)和较短的DIRL(P <0.05)之间存在关联。对于伊斯特拉普拉门卡(Istrian Pramenka)品种,位于g.17355458的T / T基因型与较高的生育力(P <0.05)和较短的DRIL(P <0.05)正相关。对于Jezersko-Solčavska品种,在光周期降低的情况下,g / G基因型在17355452位的母羊产羔更多,而A / A基因型的母羊在更多的时期产羔多(P <0.05)。增加光周期。研究的不同多态性与斯洛文尼亚三个品种的繁殖性能有关。对于伊斯特拉普拉门卡(Istrian Pramenka)品种,位于g.17355458的T / T基因型与较高的生育力(P <0.05)和较短的DRIL(P <0.05)正相关。对于Jezersko-Solčavska品种,在光周期降低的情况下,g / G基因型在17355452位的母羊产羔更多,而A / A基因型的母羊在更多的时期产羔更多(P <0.05)。增加光周期。研究的不同多态性与斯洛文尼亚三个品种的繁殖性能有关。对于伊斯特拉普拉门卡(Istrian Pramenka)品种,位于g.17355458的T / T基因型与较高的生育力(P <0.05)和较短的DRIL(P <0.05)正相关。对于Jezersko-Solčavska品种,在光周期降低的情况下,g / G基因型在17355452位的母羊产羔更多,而A / A基因型的母羊在更多的时期产羔更多(P <0.05)。增加光周期。研究的不同多态性与斯洛文尼亚三个品种的繁殖性能有关。当光周期降低时,17355452的羔羊更多,而在光周期增加的期间,具有A / A基因型的母羊的羔羊更多(P <0.05)。研究的不同多态性与斯洛文尼亚三个品种的繁殖性能有关。当光周期降低时,17355452的羔羊更多,而在光周期增加的期间,具有A / A基因型的母羊的羔羊更多(P <0.05)。研究的不同多态性与斯洛文尼亚三个品种的繁殖性能有关。
