The impact of Ig G levels on routine clinical biochemistry parameters i

Summary The minimisation of neonatal mortality is critical for the success of an animal vigilance programme. The period between calving and weaning is the most crucial period in the animals life. A major management tool that could be used to go down health problems in calves is feeding with colostrum. Colostrum is rich in energy, protein and vitamins (especially vitamins A, D, E and B12). Most importantly, colostrum is essential for newborns, in that it contains high levels of immunoglobulins, which transfer passive claim to the calf, and thereby, enable it to fight with infections. The aim of the present study was to determine the correlation between serum Ig G levels and routine biochemical parameters in neonatal Holstein calves given colostrum. For this purpose, serum was extracted from blood samples collected from 79 calves within 24-48 hours of calving. The passive transfer status of the calves was determined by measuring the Ig G message of serum by ELISA. Based on their serum Ig G levels, the calves were divided into 3 groups (insufficient n=13 partial n=14 and customary passive transfer n=52). Serum ALT, AST, GGT, ALP, LDH activities and serum BUN, creatinine, albumin, total protein, total bilirubin, triglyceride, cholesterol, and glucose levels were analysed. A statistically significant increase was determined in the serum GGT natural action and total protein and urea levels of calves with normal passive immunity transfer by colostrum, compared to the other passive transfer groups (p0.05).Key words Colostrum, Passive Transfer, Calf, Clinical Biochemistry admittanceThe minimisation of neonat... ...Passive transfer of colostral immunglobulins in calves.
