Journal of Animal Production Sample Structured Abstract

ABSTRACT

Objective: In the study, the changes in the immunoglobulin levels of the Saanen goats fed with colostrum were determined during the three days after birth.

Material and Methods: The animal material of the research consists of 11 goats and 11 of their kids. Colostrum samples were taken from the goats in three repetitions (at birth, at 24th and 48th hours after birth). Changes in IgA, IgM, and IgG levels were examined individually in 33 (11 x 3) colostrum samples taken at birth and 24th and 48th hours after birth.

Results: IgA, IgM and IgG levels at birth and 24 and 48 hours after birth for Saanen goats were 0.11-1.98-1.88 mg/ml, 0.28-0.95-14.01 mg/ml and 0.25-0.96-13.53 mg/ml, respectively. The IgA, IgM, IgG levels of kids at birth, 24, and 48 hours after birth were 0.76-1.11-19.22 mg/ml, 0.58-1.02-18.42 mg/ml and 0.53-1.24-21.60 mg/ml, respectively. The effect of birth type and gender and parity on IgA, IgM, and IgG levels were not significant, while the effect of the time-dependent change was linearly and quadratically significant (P <0.01).

Conclusion: In the colostrum secreted in the postpartum period in goats, it is necessary for the immune substances to be taken as soon as possible since the rate of passage of the immune substances transferred through the intestinal epithelium by this way decreases in time.
