Data Set on efficacy of vagina electrical resistance measurement and blood parameters in West African dwarf goats synchronized using Ovsynch and Double Prostaglandin protocol.

One of the major constraints to good reproductive performance in West African dwarf (WAD) goats’ reproduction is low estrus detection. Ovsynch and Double prostaglandin are two common estrous synchronization protocols with main challenge of precise insemination timing. These data sets are results of study designed to measure the vaginal mucus electrical resistance (ERVM) as an indicator for estrus, ovulation, and insemination in 12 WAD does. Animals were randomly divided into; Group 1 (G1) comprised 6 does which were treated with two doses of prostaglandin analog (PGF2α) administered 11 days apart while Group 2 (G2) comprised 6 does that were synchronized using the Cosynch protocol (Day 1 – GnRH, Day 7 - PGF2α and Day 9 – GnRH). The VER reading was determined using Draminski heat detector. Per animal, the doe was restrained, using the index finger and thumb, the vulva was opened and the heat detector (disinfected using Savlon and dried with paper towel) was inserted at angle 45odegree into the vagina until it meets the fornix part of the vagina. The probe was then rotated twice and then the VER reading taken. The VER readings of the animals were taken 12 hourlies (Morning 6 – 7 AM and evening 6 – 7 PM) throughout the period of the experiment. Blood samples were collected from WAD doe in Group 1 on day 0, 7, 11, 12, 13 and 14 while those in Group 2 on day 0, 7, 9, 10, and 11 respectively. Mean vaginal electrical resistance (VER) values ranged from 405 ± 39 to 788 ± 160 in Group 1 and 352 ± 25 to 1098 ± 166 in Group 2. Estrus onset correlated with lowest VER post-treatment, with 40% in both groups showing signs within 36 hours, and patterns persisted. Progesterone declined and spiked in Group 1 on days 7-11, then dropped sharply on days 12-13; estradiol rose as progesterone fell. Group 2's progesterone spiked on day 10, inversely related to estradiol. A consistent pattern emerged: low VER, high estradiol, and low progesterone signified estrus. Day 13 saw 40% of Group 1 does in estrus, reflecting low VER and high estradiol (190.6 ± 31.4 µmol/l), similarly in Group 2. The current data contributes to available reports on efficacy of VER, estradiol, and progesterone as reliable predictors of estrus onset and highlights their role in reproductive management. Data can be used for further studies, validation of similar reports in ruminant reproduction and application of timed artificial insemination protocols.

西非矮小山羊（WAD）繁殖性能的重要限制之一为发情期检测率低。同步发情技术（Ovsynch）和双前列腺素法是两种常见的发情同步方案，其主要的挑战在于精确的受精时机。本数据集为研究设计的成果，旨在测量12头WAD母山羊的阴道粘液电阻（ERVM）作为发情、排卵和受精的指标。动物被随机分为两组；第一组（G1）包括6头母山羊，分别于相隔11天的时间内接受两次前列腺素类似物（PGF2α）剂量治疗，而第二组（G2）包括6头母山羊，采用Cosynch方案进行同步发情（第1天——GnRH，第7天——PGF2α，第9天——GnRH）。阴道电阻率（VER）的测量采用Draminski热检测器完成。对每头动物，使用食指和中指固定，打开阴唇，将消毒后并用纸巾擦拭干净的热检测器以45度角插入阴道，直至遇到阴道穹窿部分。随后，探头旋转两次，并记录VER读数。在整个实验期间，动物的VER读数每12小时进行一次（早晨6-7点，傍晚6-7点）。第一组母山羊在实验当天、第7天、第11天、第12天、第13天和第14天收集血液样本，而第二组在实验当天、第7天、第9天、第10天和第11天分别收集。第一组的平均阴道电阻率（VER）值介于405 ± 39至788 ± 160之间，第二组介于352 ± 25至1098 ± 166之间。发情开始与治疗后最低的VER值相关，两组中各有40%的动物在36小时内显示出发情迹象，且模式持续存在。第一组的孕酮在第7-11天下降并迅速上升，然后在第12-13天急剧下降；而随着孕酮的下降，雌二醇水平上升。第二组的孕酮在第10天达到峰值，与雌二醇呈负相关。出现了一种一致的模式：低VER、高雌二醇和低孕酮标志着发情。第13天，第一组40%的母山羊进入发情期，反映低VER和高雌二醇（190.6 ± 31.4 µmol/l），第二组情况类似。当前数据有助于现有关于阴道电阻率（VER）、雌二醇和孕酮作为发情开始可靠预测指标的研究报告，并强调了它们在繁殖管理中的重要作用。数据可用于进一步研究，验证类似关于反刍动物繁殖的报告，以及定时人工授精方案的应用。
