Determination of Antioxidant Capacity and Free Radical Scavenging Activity of Milk from Native Cows (Bos Indicus), Exotic Cows (Bos Taurus), and Riverine Buffaloes (Bubalus Bubalis) Across Different Lactation Stages
Description
The aim of this study was to evaluate comparative changes in total antioxidant capacity and free radical scavenging activity of milk during lactation in different cattle types and buffaloes. Milk samples from a total of 96 healthy animals of Sahiwal cows (Indian native cattle), Karan Fries cows (Cross-bred), Holstein Frisian cows (exotic cattle) and Murrah buffaloes (Riverine buffaloes) were collected at different lactation stages; early lactation (5-15 days), peak (30-60 days), mid (100-140 days) and late lactation (>215 days). The total antioxidant capacity (TAC) of milk was measured by ferric reducing/antioxidant power assay (FRAP) and free radical scavenging activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals. TAC in milk was higher during early lactation. Similar results were observed for DPPH radical scavenging activity of the samples. The data suggested that milk during the early lactation period of dairy cows and buffaloes had higher content of antioxidants in comparison to other stages of lactation.
