Abstract：
The health of the gastrointestinal tract in cattle is one of the factors influencing adequate nutrient absorption and body weight gain. This study aimed to evaluate the prevalence of lesions found in the abomasum of Polish fattening Holstein-Friesian bulls. A total of 149 abomasa from adult bulls from two voivodeships of central Poland were inspected for pathologicalanatomic position (displacement, volvulus), impaction, mucosal membrane lesions (inflammation, hyperplasia), and signs of parasite infestation(Moroccan leather, worm nodules) in one of the Polish abattoirs just after slaughter. Among all the examined males no lesions were observed in only 8 individuals. The most common findings were erosions (75.8%) and type 1 ulcerations (48.3%) of the body, pylorus, or both locations. Signs of parasite infestations were observed in 78.5% of the inspected animals. Significant differences correlated with age were found in the prevalence of healed ulcers, and between voivodeships in the prevalence of type 2 ulcers. The findings of this study indicate that most fattening bulls in Poland suffer from subclinical forms of abomasa inflammation (both diffuse and focal) and middle-large abomasum parasites invasions, which can influence the economics and profitability, as well as welfare, of livestock production.
摘要：
牛胃肠道的健康是影响足够营养吸收和体重增加的因素之一。这项研究旨在评估波兰育肥荷斯坦-弗里斯公牛的皱胃中发现的病变的患病率。检查了来自波兰中部两个省的成年公牛的149头病态解剖位置（位移，扭转),撞击,粘膜病变（炎症，增生)，和寄生虫感染的迹象(摩洛哥皮革，蠕虫结节）在屠宰后的波兰屠宰场之一中。在所有被检查的男性中，只有8个人没有观察到病变。最常见的发现是身体的糜烂（75.8％）和1型溃疡（48.3％），幽门,或两个地点。在78.5%的检查动物中观察到寄生虫侵染的迹象。发现溃疡愈合的患病率与年龄相关存在显着差异，在2型溃疡的患病率之间。这项研究的结果表明，波兰的大多数育肥公牛都患有亚临床形式的皱胃炎症（弥漫性和局灶性）和中大型皱胃寄生虫入侵，会影响经济和盈利能力，以及福利，畜牧业生产。
