In a cohort study, 40 pig finishing herds were selected: twenty pig herds with a low and twenty pig herds with a high prevalence of several pathological lesions recorded at slaughter in a six-month period before the start of the study. Blood samples were taken from 20 pigs per herd at the end of the finishing period to investigate haematological and clinicochemical profiles. There was only a significant difference in serum albumin concentration between the low and high lesion prevalence groups. There were distinct differences in blood profiles between pig herds, but also between batches of pigs within a herd, housed in different compartments. Differences between castrated males and gilts were also demonstrated with respect to mean values of the blood variables haemoglobin, iron, copper, beta-globulin, eosinophils and segmented neutrophils. However, the differences were not of a biologically important magnitude. The mean values of the blood variables pepsinogen and lymphocytes differed significantly between pig herds from the two participating integration groups. Pigs with a higher albumin concentration, a lower gamma-globulin concentration, a higher copper concentration and a higher creatine kinase activity in serum showed a higher daily weight gain.
在一项队列研究中，选取了40个育肥猪群：在研究开始前的六个月期间，屠宰时记录到几种病理损伤患病率较低的20个猪群和患病率较高的20个猪群。在育肥期结束时，从每个猪群的20头猪采集血样，以调查血液学和临床化学指标。低患病率组和高患病率组之间仅血清白蛋白浓度存在显著差异。不同猪群之间的血液指标存在明显差异，而且同一猪群中饲养在不同栏舍的不同批次猪之间也存在差异。去势公猪和后备母猪在血红蛋白、铁、铜、β-球蛋白、嗜酸性粒细胞和分叶核中性粒细胞等血液变量的平均值方面也存在差异。然而，这些差异在生物学上并不具有重要意义。来自两个参与整合组的猪群之间，血液变量胃蛋白酶原和淋巴细胞的平均值存在显著差异。血清中白蛋白浓度较高、γ-球蛋白浓度较低、铜浓度较高以及肌酸激酶活性较高的猪日增重较高。
