Effects of hoof trimming on feed consumption, milk yield, oxidant and antioxidant system in dairy cows with hoof deformities

Abstract

In this study is objectived to reveal the importance of hoof trimming (HT) in cows by determining the changes in feed consumption, milk yield, oxidant, and antioxidant parameters in the days before and after HT in cows with hoof deformities. This research was conducted on 12 female Brown Swiss dairy cows late lactation period that had healthy hooves showing symptoms lameness due to hoof deformities. Daily feed consumption and milk yield findings before and after HT were recorded. Total oxidant capacity (TOC) and total antioxidant capacity (TAC) tests for determination of oxidative stress index in serum in blood samples, for the evaluation of antioxidant potential; glutathione peroxidase (GSH-Px), glutathione (GSH), superoxide dismutase (SOD) enzyme, Vitamin E, A, and C levels were measured. According to the findings of this study, after HT increased feed consumption and milk yield in dairy cows (P
