Rabbit production holds significant relevance in modern agriculture due to its potential as a sustainable source of high-quality protein and efficient feed conversion, contributing to food security and economic diversification. Nevertheless, studies incorporating feto-maternal monitoring in this species are uncommon. This review gathers research on the monitoring and evaluation of factors affecting rabbit gestation, providing a better understanding of the causes of prenatal development abnormalities. These include studies regarding how chronic maternal hypertension, gestational diabetes, maternal stress, ectopic gestation, maternal uterine ischemia and fetal hypoxia, intrauterine growth restriction, superfetation, maternal age, maternal nutritional status, maternal physical condition, maternal and embryonic genotype, and the intrauterine location of rabbit fetuses can potentially impact rabbits' reproduction and maternal and fetal health. Among other monitoring techniques, ultrasonography, considered one of the best tools for diagnosing pregnancy and conducting follow-up, is also reviewed. Details on measurable fetal-development parameters in rabbits and precautions to be considered before and during the examination are also provided. Additional studies are required to understand why some events occur and their consequences throughout gestation, allowing the determination of new biomarkers or cut-offs that can be helpful for early diagnosis and improve reproductive efficiency.
由于兔子具有成为优质蛋白质可持续来源以及高效饲料转化率的潜力,对现代农业具有重要意义,有助于粮食安全和经济多元化。然而,在该物种中纳入胎儿 - 母体监测的研究并不常见。本综述收集了有关影响兔子妊娠的因素监测和评估的研究,以便更好地理解产前发育异常的原因。这些因素包括慢性母体高血压、妊娠期糖尿病、母体应激、异位妊娠、母体子宫缺血和胎儿缺氧、宫内生长受限、异期复孕、母体年龄、母体营养状况、母体身体状况、母体和胚胎基因型以及兔子胎儿的宫内位置如何可能影响兔子的繁殖以及母体和胎儿健康。在其他监测技术中,超声检查被认为是诊断妊娠和进行随访的最佳工具之一,本文也对其进行了综述。还提供了兔子可测量的胎儿发育参数的详细信息以及检查前和检查期间应考虑的注意事项。需要更多研究来了解整个妊娠期某些事件发生的原因及其后果,从而确定有助于早期诊断和提高繁殖效率的新生物标志物或临界值。
