Abstract :In this study is objectived to reveal the importance of hoof trimming insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(TOC); and total antioxidant capacity insert ignore into journalissuearticles values(TAC); tests for determination of oxidative stress index in serum in blood samples, for the evaluation of antioxidant potential; glutathione peroxidase insert ignore into journalissuearticles values(GSH-Px);, glutathione insert ignore into journalissuearticles values(GSH);, superoxide dismutase insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(P 0.05); levels did not change significantly. Results of this study showed that hoof trimming, the oxidant system was suppressed and the antioxidant system was supported in dairy cows with hoof deformities dad healthy hooves.
