Umbilical outpouchings (UOs) in pigs are of welfare and production concern in Danish pig herds. One of the challenges is the transportation of these animals due to the size of the UOs and ulcerations on them. With certain precautions and an approval from a veterinarian, pigs with UOs may be transported, however, UOs are associated with several intra-abdominal lesions, e.g. peritonitis and incarceration, which may worsen during the process of transportation. The prevalence and characterization of intra-abdominal lesions associated with UOs following transportation has not been investigated. Therefore, the objective of the present study was to evaluate lesions associated with the intestines and peritoneum in slaughter pigs with wounded UOs following transportation to an abattoir.
A cross-sectional study involving three conventional Danish pig herds was conducted comprising 96 slaughter pigs with wounded UOs transported to an abattoir. Following slaughter the UOs with accompanying intestines were examined pathologically. Three distinct morphological categories were present: hernia, enterocystoma and herniating enterocystoma. Intra-abdominal lesions were present in 72% of the animals, representing 65% (44/68) of the hernias, 77% (10/13) of the enterocystomas, and 100% (15/15) of the herniating enterocystomas. Several different lesions were found like bleedings, acute/chronic peritonitis and hypertrophy of the intestinal muscular layers.
The prevalence of intra-abdominal lesions in pigs transported with a wounded UO was found to be high independent of the underlying condition, and it is clear that these pigs possess a vulnerable group of animals, especially during physical stressful situations like transportation. More information is needed regarding the prevalence of intra-abdominal lesions in UO pigs without wounds on the UO. The results provide valuable knowledge, that can be used when examining and evaluating UO pigs before transportation.
丹麦猪群中猪的脐部膨出（UOs）关乎福利和生产。其中一个挑战是这些动物的运输，因为脐部膨出的大小及其上的溃疡。在采取某些预防措施并获得兽医批准后，有脐部膨出的猪可以运输，然而，脐部膨出与几种腹腔内病变相关，例如腹膜炎和肠管嵌顿，在运输过程中这些病变可能会恶化。运输后与脐部膨出相关的腹腔内病变的患病率和特征尚未得到研究。因此，本研究的目的是评估运输到屠宰场后有受伤脐部膨出的屠宰猪的肠道和腹膜相关病变。
进行了一项横断面研究，涉及丹麦三个传统猪群，包括96头运输到屠宰场的有受伤脐部膨出的屠宰猪。屠宰后，对带有伴随肠道的脐部膨出进行病理检查。存在三种不同的形态学类别：疝、肠囊肿和疝出性肠囊肿。72%的动物存在腹腔内病变，分别占疝的65%（44/68）、肠囊肿的77%（10/13）和疝出性肠囊肿的100%（15/15）。发现了几种不同的病变，如出血、急性/慢性腹膜炎和肠肌层肥大。
发现运输时有受伤脐部膨出的猪腹腔内病变的患病率很高，与潜在病情无关，显然这些猪是一群易受伤害的动物，特别是在运输等身体应激情况下。关于脐部膨出无伤口的猪腹腔内病变的患病率，还需要更多信息。这些结果提供了有价值的知识，可用于运输前检查和评估有脐部膨出的猪。
