摘要
This study examined the artificial fertilization efficiency of crossbred goats from a farmhouse using frozen semen. Electrostimulation was used to ejaculate and collect semen to assess the artificial fertilization efficiency of crossbred goats. The sperm concentration, vitality, and vitality after melting were investigated. The sperm volume was within 2.5~3 ml, and the concentration was 21~25 × 108/ml for each male crossbred goat. The melted semen had high vitality (≥90%). An IDEXX Rapid Visual Pregnancy Test kit was used for an earlier diagnosis of the pregnancy and to determine the pregnancy rate of fertilization using frozen-thawed semen. The reproductive performance of the artificially fertilized crossbred goats had the highest delivery rate (68%) from Farm C and the lowest delivery rate (45%) from farm A. The delivery rate through artificial fertilization was equal to the fertilization rate according to early pregnancy diagnostic kits. The artificial insemination efficiency was 45~68%. These findings can be used as the basis for improvement and breeding goats in goat farms and livestock research institutes.

这项研究检查了使用冷冻精液从农舍杂交山羊的人工受精效率。使用电刺激射精并收集精液，以评估杂交山羊的人工受精效率。研究精子的浓度，活力和融化后的活力。每只雄性杂交山羊的精子体积在2.5〜3 ml之内，浓度为21〜25×108 / ml。精液融化后活力较高（≥90％）。使用IDEXX快速视觉怀孕检测试剂盒对妊娠进行早期诊断，并使用冷冻融化的精液确定受精的妊娠率。人工受精杂交山羊的繁殖性能最高，C农场为68％，A农场为45％。通过人工受精的山羊的受精率等于早孕的受精率诊断套件。人工授精效率为45〜68％。这些发现可作为在山羊农场和牲畜研究机构改良和育种山羊的基础。
