Abstract

Endometritis and postpartum dysgalactiae syndrome are common postpartum disorders in sows revealing antimicrobial treatment.

This study evaluated the influence of the intrauterine application of a phytotherapeutic agent (EucaComp©) after farrowing containing essences of marjoram, marigold, melissa and eucalyptus and other sow-related parameters on the uterine involution.

In total, 150 Landrace x Large white sows (parity 1–9) were divided randomly into three groups (no intervention (Control), 300 ml sodium chloride (Placebo) and 300 ml of phytotherapeutic agent (Phytotherapeutic)). Several sow-related parameters were assessed such as, parity, Body Condition Score (1–5), birth induction (Yes/No), and feed intake. On days 2, 3, 5, 7 and 21 postpartum, uterine involution was assessed by measuring the diameter on three locations of the uterine horns using ultrasound.

The mean uterine diameter changed from 36.4 ± 6.5 mm on day 2–20.4 ± 5.9 mm on day 7 (reduction of 43.81 %) and 14.0 ± 3.2 mm on day 21 (reduction of 61.15 %). No significant differences between the groups and the regression of uterine involution were detected. However, birth induction had a positive effect on uterine involution, increasing the relative uterine involution by 8 %, whereas lack of appetite postpartum, lead to a decrease of 7 % until day 7. An suboptimal BCS (≤2; ≥4) and a parity ≥2 lead to a reduction of uterine involution regression on day 21 by 7 and 5 %. In conclusion, a single postpartal intrauterine application of a phytotherapeutic agent demonstrated no significant impact on uterine involution, while sow-specific and management factors remained pivotal.

一种植物治疗药物的宫内应用和其他参数对母猪自由分娩系统子宫复旧的影响

子宫内膜炎和产后泌乳不良综合征是母猪常见的产后疾病，需要抗生素治疗。本研究评价了分娩后宫内应用含有马郁兰、万寿菊、梅莉香和桉树等妊娠相关参数的植物治疗剂（EucaComp©）对子宫复旧的影响。150头长白×大母猪（胎次1 ~ 9）随机分为3组(无干预组（对照组）、300 ml氯化钠组（安慰剂组）和300 ml植物治疗剂组（植物治疗剂组）。评估了几个与母猪相关的参数，如胎次、体况评分（1-5）、分娩诱导（是/否）和采食量。于产后第2、3、5、7、21天，采用超声测量子宫角三个部位直径，评估子宫复旧情况。子宫平均直径由第2天的36.4±6.5 mm（减少43.81%）和第21天的14.0±3.2 mm（减少61.15%）改变为第7天的20.4±5.9 mm。两组间子宫复旧程度差异无统计学意义。然而，引产对子宫复旧有积极作用，使相对子宫复旧增加8%，而产后食欲不足，导致子宫复旧减少7%，直到第7天。次优BCS(≤2；胎次≥4)和胎次≥2导致第21天子宫复旧消退分别减少7%和5%。总之，单次产后宫内应用植物治疗药物对子宫复旧没有显著影响，而母猪特异性和管理因素仍然是关键。
