Variation Regularity and Correlation Analysis of Blood Biochemical Indicators in Dairy Goats during Different Lactation Stages
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 pa-rameters to reflect the physiological and metabolic status and overall health conditions of dairy goats at dif-ferent 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 cor-relations 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 lac-tation 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 manag-ing goat farms.
