Detection and analysis of serum physiological and biochemical indexes of fetal and newborn cattle
The aim of this experiment was to compare the physiological and biochemical indexes of fetal and neonatal bovine serum.Serum was collected aseptically from five healthy,healthy and nutrition-free 8-month-old female cows of Holstein breed and 5 newborn cows(with similar body weight)who did not eat at 14 h after birth.Serum appearance characteristics(color and concentration)were directly observed,and serum endotoxin content,osmotic pressure and serum biochemical indexes were detected.The results showed that the serum endotoxin content and osmotic pressure of fetal and newborn cattle were in line with the standard.The coefficient of variation of creatinine(CREA),gamma-glutamyltranspeptidase(GGT)and uric acid(UA)in fetal and newborn cattle was higher,and the degree of dispersion was larger.The coefficient of variation of albumin(ALB)is low and the degree of dispersion is small.Serum CREA and UA contents of fetal cattle were extremely higher than those of newborn cattle(P<0.01),total protein(TP),globulin(GLB)contents and GGT activity were extremely lower than those of newborn cattle(P<0.01).The results show that there is no obvious difference in physiological indexes between fetal and newborn bovine serum.Some biochemical indexes can distinguish fetal bovine serum or newborn bovine serum.
