Changes in Total Antioxidant Contents of Colostrum of Honamli and Hair Goat Breeds During the First 5 Days of Parturition

Colostrum is the primary source of initial acquired immunity and provides an antioxidative protection of newborn. The aim of present study was to analyze and compare the changes in total antioxidant capacity (TAC) and total phenolic contents (TPCs) colostrum's of Honamli and Hair goat breeds on the first 5 days after parturition. The spectrophotometric ABTS method and the Folin-Ciocalteu assay were used. TAC and TPCs values were decreased gradually as the transition period advances. Both values were highest on the day first of calving as compared to rest of the days. Honamli goat colostrum samples had a higher TAC value than Hair goat and was showed significant (P<0.05) difference amongst the breeds. However, TPCs in Hair goat colostrum showed highly significant (P<0.05) difference than those of Honamli goat. In conclusion, TAC and TPC values in goat colostrum showed differences among goat breeds and exhibits daily rational changes.
