The aim of this study was to identify the prevalence of pathological lesions in pigs from small-scale farms and to determine associations between pathological lesions and hematological parameters, and carcass and meat quality in slaughtered pigs. The study was conducted on 625 pigs (~115 kg) originating from 20 small-scale farms. Any signs of pneumonia, pleurisy, pericarditis, and liver milk spots were recorded as present or absent. Complete blood count was investigated. The following carcass quality parameters were measured: live, hot and cold carcass weights, cooling loss, dressing percentage, backfat thickness, and meatiness. Meat pH and temperature were measured 45 min postmortem. Of the 625 examined pigs, 41.8% had pneumonia, 23.5% pleurisy, 2.7% pericarditis, and 29.9% liver milk spots. The presence of pathological lesions in slaughtered pigs adversely affected hematological parameters, reduced live, hot and cold carcass weights, and meatiness and had deleterious effects on meat quality (higher pH45min and higher prevalence of dark, firm and dry meat). In conclusion, this study showed a high prevalence of pathological lesions in slaughtered pigs, indicating serious health problems in smallholder pig production systems. The presence of single and, especially, multiple pathological lesions in slaughtered pigs negatively affected hematological parameters, and carcass and meat quality.

各种宰后病理性病变的屠宰场记录及其对屠宰猪car体和肉品质的影响。

这项研究的目的是确定小规模猪的病理性病变的患病率,并确定病理性病变与血液学参数以及屠宰猪的car体和肉质之间的关联。该研究是对来自20个小型农场的625头猪(〜115公斤)进行的。记录有无肺炎,胸膜炎,心包炎和肝牛奶斑点的迹象。调查了全血细胞计数。测量了以下car体质量参数:鲜,热和冷car体重量,冷却损失,敷料百分比,后脂肪厚度和肉味。死后45分钟测量肉的pH和温度。在所检查的625头猪中,有41.8%患有肺炎,23.5%胸膜炎,2.7%心包炎和29.9%肝奶斑。屠宰猪的病理性病变对血液学参数产生不利影响,降低了live体的生,冷,热重量以及肉质,并对肉质产生了有害影响(pH45min较高,深色,坚硬和干燥肉的患病率较高)。总而言之,这项研究表明在屠宰猪中病理病变的患病率很高,这表明小农户养猪系统中存在严重的健康问题。屠宰猪中存在单个(尤其是多个)病理病变会对血液学参数以及car体和肉质产生负面影响。这项研究表明,屠宰猪的病理病变患病率很高,表明小农户养猪系统中存在严重的健康问题。屠宰猪中存在单个(尤其是多个)病理病变会对血液学参数以及car体和肉质产生负面影响。这项研究表明,屠宰猪的病理病变患病率很高,表明小农户养猪系统中存在严重的健康问题。屠宰猪中存在单个(尤其是多个)病理病变会对血液学参数以及car体和肉质产生负面影响。
