摘要:

氯前列醇钠作为人工合成的前列腺素类似物被广泛的应用于诱导各种母畜的分娩。卡贝缩宫素作为一种具有长效特性的新型催产素类样分子,有望在母猪分娩过程中替代缩宫素起到收缩子宫启动分娩的作用。试验一主要对氯前列醇钠注射部位和剂量进行研究,将母猪随机分为自然分娩组(n=74)、2 mL肌肉注射组(n=52)、2 mL后海穴注射组(n=63)和1 mL后海穴注射组(n=57)。研究结果表明,2 mL后海穴注射组的母猪分娩时间上表现更为集中,产仔持续时间最短(228 min),白天分娩比例最高(90.48%)。说明通过调整母猪注射氯前列醇钠时间、剂量以及部位等因素能够一定程度的缩短母猪产仔时间,提高母猪白天分娩率。试验二主要对卡贝缩宫素(CBT)与氯前列醇钠的联合应用进行研究,试验将母猪随机分为自然分娩组(n=81)、氯前列醇钠注射组(n=70),CBT注射组(n=67),氯前列醇钠+CBT注射组(n=64)。研究结果表明,氯前列醇钠与卡贝缩宫素联合应用能够缩短母猪产仔持续时间(205 min),并且大幅提高母猪在白天工作时间分娩比例(95.31%)。

Abstract:

As a synthetic prostaglandin analog, cloprostol sodium is widely used to induce delivery in various livestock. Carbetocin (CBT) is an oxytocin-like molecule with long-acting properties which targets the same receptors on the myometrium as oxytocin. It is currently considered to be a substitute for oxytocin in the sows to contract the uterus to initiate delivery. The first trial mainly studied the injection site and dosage of cloprostol sodium. The sows were randomly divided into natural delivery group (n=74), 2 mL intramuscular injection group (n=52), 2 mL Houhai acupoint injection group (n=63) and 1 mL Houhai acupoint injection group (n=57). The results of the study showed that the sows in the 2 mL Houhai acupoint injection group showed more synchronized farrowing time, with the shortest farrowing duration (228 min) and the highest daytime delivery rate (90.48%). It was indicated that the sows’ farrowing duration can be shortened and the daytime delivery rate of sows can be improved to a certain extent by adjusting the injection time, dosage and location of sodium cloprostol. The second trial mainly studied the effect of carbetocin (CBT) in combination with cloprostol sodium. The sows were randomly divided into natural delivery group (n=81), cloprostol sodium injection group (n=70), and CBT injection group (n=67), cloprostol sodium+CBT injection group (n=64). The results of the study showed that the combined application of cloprostol sodium and carbetocin could shorten the farrowing duration of sows (205 min), and significantly increased the daytime delivery rate in the working hours (95.31%).
