All the animals were evaluated for foot lesions before the start of experiment and then at the end of feeding trial.A significant decrease in rumen liquor pH and sodium concentration was observed in the feeding group animals with the progress of time.TVFA concentration increased in the feeding group with rise in acetate, propionate and butyrate levels at the end of the trial.High prevalence of heel erosions, white line haemorrhages, white line fissures and overgrown soles were observed in the feeding group animals at the end of trial along with an increase in rear leg view index.
