不同泌乳时期奶山羊血液生化指标变化规律及其相关性分析

Variation Regularity and Correlation Analysis of Blood Biochemical Indicators in Dairy Goats during Different Lactation Stages

试验旨在探究西农萨能奶山羊不同泌乳时期血液生理生化相关指标的变化规律以及这些指标间的相关性,以反映不同泌乳期奶山羊生理代谢状况及机体健康情况。采集不同泌乳时期150只西农萨能奶山羊血样,测定其血液生理生化指标进行相关性分析,以探究泌乳阶段等非遗传因素对奶山羊血液生化指标的影响。研究结果显示:(1)泌乳时期对西农萨能奶山羊血液中总蛋白水平(Total Protein)、白蛋白水平(Albumin)、球蛋白水平(Globular Protein)、白蛋白与球蛋白比值(A/G)、葡萄糖水平(Glucose)、总胆固醇水平(Total Cholesterol)和甘油三酯水平(Triglyceride)等指标均有显著影响。(2)TP与GLB、ALB与A/G、ALB与BUN、A/G与GLB、A/G与GLU在各个泌乳时期均有显著相关性(P<0.05)。奶山羊血液生化指标受不同泌乳阶段影响显著,且血液生化指标在不同的泌乳阶段均有显著相关性。研究结果可全面反映奶山羊的健康生理状态,为羊乳品质改善、营养调节供给和羊场饲养管理提供理论参考。

The aim of this study was to investigate alterations in blood physiological and biochemical parameters of Xinong Saanen dairy goats at different lactation stages and the correlations among these parameters to reflect the physiological and metabolic status and overall health conditions of dairy goats at different lactation stages.Blood samples from 150 Xinong Saanen dairy goats at different lactation stages were collected to determine their blood physiological and biochemical indicators for correlation analysis,in order to explore the influence of non-genetic factors on blood biochemical indicators in Xinong Saanen dairy goats.The findings indicated that:(1)lactation stage significantly influenced various blood parameters such as total protein(TP),albumin(ALB),globulin(GLB),albumin/globulin ratio(A/G),glucose(GLU),total cholesterol(TC),and triglyceride(TG)in Xinong Saanen dairy goats.(2)Significant correlations were observed among TP and GLB,ALB and A/G,ALB and BUN,A/G and GLB,A/G and GLU at different lactation periods(P<0.05).Blood biochemical indicators are significantly affected by lactation periods,and the significant correlations have been observed among the blood biochemical indicators in dairy goats.These findings comprehensively reflect the health and physiological status of dairy goats,providing theoretical references for improving goat milk quality,adjusting nutritional supply,and managing goat farms.
