Study of blood hematological and biochemical indicators related to average daily gain in Yorkshire pigs
摘要
Abstract
This study aimed to determine the effects of hematological and biochemical indicators on average daily gain(ADG)in pigs,and to identify potential biomarkers associated with growth performance.A total of 198 Yorkshire pigs were used as experimental subjects.After measuring growth performance traits such as ADG,blood samples were collected from the anterior vena cava of the pigs to assess 23 hemato-logical indicators and 21 blood biochemical indicators.Subsequently,30 pigs with high ADG and 30 with low ADG were selected from the co-hort.Indicators were compared between the two groups,and partial correlation analysis was conducted between all measured parameters and ADG across the entire sample.The results showed that the high ADG group had significantly higher levels of eosinophil count(EO#)and percentage(EO%),alanine aminotransferase(ALT),low-density lipoprotein cholesterol(LDL-C),C-reactive protein(CRP),and im-munoglobulin M(IgM),as compared with the low ADG group(P＜0.05).In contrast,basophil percentage(BASO%),mean platelet vol-ume(MPV),and high-density lipoprotein cholesterol(HDL-C)were significantly lower in the high ADG group(P＜0.05).According to the partial correlation analysis,BASO%was significantly negatively correlated with ADG(P＜0.05).Additionally,parameters including red cell distribution width standard deviation(RDW-SD),white blood cell count(WBC),and lymphocyte percentage(LYMPH%)exhibited trends toward correlation with ADG.This study identified multiple blood parameters closely linked to ADG in pigs,encompassing physiologi-cal aspects such as immune function(BASO,WBC,LYMPH)and hematological morphology(RDW-SD,RDW-CV).These findings pro-vided a hematological basis for understanding the physiological regulation of ADG in pigs and suggested potential biomarkers for early predic-tion of growth performance and breeding selection.关键词
