        Lameness and its consequences are one the most important causes of economic losses in dairy farming. Lameness is a multifactorial condition that can be managed by knowing its risk factors and their importance in specific farms and conditions. Current article focusses on understanding value of causative agents and risk factors in a condition like lameness and evaluating risk factors in dairy farms. Risk factors were classified into farm building or environment factors (Top roof of the barns and its slop and height, flooring and its drainage, distance to milking parlour, milking parlour collecting area, alleys and foot bathes) Managerial factors (Nutrition and feeding, overstocking, herd composition, days in milk, cow movements in the herd, slurry cleaning and drainage, bedding) environment (Temperature, humidity, raining, wind, altitude, heat stress management) and cow factors (body condition scoring, milk production, concurrent diseases, time budgeting). Each factor was analysed in Iran’s dairy farming situation and applied methods of its management were discussed. Manuscript profile

        Digital lesions were treated by corrective hoof trimming, nonstroidal anti-inflammatory drugs and hoof blocks on a sound claw. Any claw lesions including sole ulcer, white line diseases, toe ulcer, digital wall lesions, penetrating interdigital necrobacillosis should be treated using hoof blocks. Block height estimated as 25, width 50 and length 110 millimeters. Sound claw should be prepared for block adhesion with no eminence or any rugged part. The block should stick to the digit slightly toward the heel. Different glue and adhesives were used in hoof blocking. Functional glues generally divided in to two groups of Epoxy and Polyurethane. These glues are strong with good elasticity. Epoxy glues are synthetic glues consisting of two parts of resin and hardener and are stronger than polyurethane glues. Polyurethane glues are more tolerant than epoxies against rusting and trauma but because of Isocyanates are dangerous in use. Methymetacrylate adhesive glues are located between polyurethane and epoxy glues with strong and elastic features. Different techniques of hoof block usage were reviewed in this current study.
