The present study aims to evaluate the efficiency of the reused controlled-internal drug-releasing devices (CIDR) compared with the hormonal method to induce estrus in the postpartum anestrus of Iraqi buffalo’s cow. Thirty-two buffalo cows aged at least three years suffering from postpartum anestrus were randomly selected and divided into four groups (eight animals each). Ultrasound was used to assess the ovarian status. Animals with any reproductive defects were excluded. In the first group (G1), a new CIDR device was used for nine days, while in G2 animals, the device of the first group was reused for nine days; while, in the G3 group, the devices were further reused either for nine days (subgroup A) or 18 days (subgroup B, received PGF2α , at day 17; GnRH, at day 19). In the fourth group (G4), the animals received an injection of PGF2α (IM, 25 mg) followed by a dose of GnRH (IM, 500 mg) after 72h, without CIDR insertion. Blood samples were collected from the jugular vein pre and post CIDR insertion. Blood samples were utilized for the progesterone level assessment. For estrus and conception rates, animals were bred by fertile buffalo bulls, and pregnancy was detected at day 45 post-mating. Results showed that there was no variation in the rates of estrus induction and conception between the uses of the new CIDR device (G1) and the reused devices (G2 and G3 subgroup A); however, in the subgroup B and G4, only 50% of the treated animals demonstrated estrus. The duration, hormone, estrus, and pregnancy rate results revealed highly significant variations between groups. After the device withdrawal, the progesterone level in G2, G3, and G4 revealed a significant decline relative to G1. In addition, the duration was positively correlated to the progesterone level, estrus, and pregnancy rate. The progesterone level during the first and second services revealed a slight negative correlation with pregnancy. In conclusion, reusing the same CIDR up to three times for estrus synchronization is highly effective inducing estrus with high conception in postpartum anestrus Iraqi buffalo cows. Additionally, it is possible to reuse the CIDR device in 9 days without administration of GnRH in the lactating buffalo cows.

本研究旨在评估重复使用的可控体内药物释放装置（CIDR）与激素法相比对伊拉克水牛产后发情的诱导效率。随机选取 32 头年龄至少为 3 岁的产后发情水牛，将其分为 4 组（每组 8 头）。用超声波评估卵巢状态。排除有生殖缺陷的动物。第一组（G1）使用新的 CIDR 装置 9 天，G2 组动物重复使用第一组的装置 9 天，G3 组动物重复使用装置 9 天（A 子组）或 18 天（B 子组，第 17 天接受 PGF2α，第 19 天接受 GnRH）。在第四组（G4）中，动物在72小时后注射PGF2α（IM，25毫克），然后再注射GnRH（IM，500毫克），但不插入CIDR。在插入 CIDR 之前和之后从颈静脉采集血液样本。血液样本用于评估孕酮水平。在发情和受孕率方面，动物由能育的水牛公牛配种，在交配后第 45 天检测是否怀孕。结果表明，使用新的 CIDR 装置（G1）和重复使用的装置（G2 和 G3 亚组 A）之间的发情诱导率和受孕率没有差异；但是，在亚组 B 和 G4 中，只有 50%的动物表现出发情。持续时间、激素、发情和妊娠率的结果显示，各组之间存在非常显著的差异。停用装置后，G2、G3 和 G4 组的孕酮水平较 G1 组显著下降。此外，持续时间与孕酮水平、发情和妊娠率呈正相关。第一次和第二次服务期间的孕酮水平与怀孕略呈负相关。总之，对产后发情的伊拉克水牛而言，重复使用同一种 CIDR 进行发情同步最多三次就能非常有效地诱导发情，并获得高受孕率。此外，在泌乳水牛身上，无需施用 GnRH 即可在 9 天内重复使用 CIDR 装置。
