        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

        Production diseases and conditions is common on intensive dairy farming which lead to pain and uncomforting or death in affected animals. Lameness has negative effects on comfort and economic issues. In many cases, lameness is associated with pain, which may change the cow's motivation to perform certain behaviors (such as walking, lying, etc.) for pain reduction and discomfort. Reduced milk yield, poor reproductive performance, shortened productive time, increased culling risk and treatment costs are the major related economic losses. Despite all the negative effects of lameness on animals and the dairy industry, limited research has been done to evaluate preventive measures. Low awareness of lameness maybe the biggest problem in its detection and control. Lameness control strategies usually include hoof trimming and treatment of motility disorders. The aim of this study is to investigate the importance of hoof trimming and its effect on claw health (effect of hoof trimming on infectious diseases, non-infectious diseases or other claw-related injuries), behavioral variables (lying time and locomotion score), physiological variables (heart rate, respiration rate, plasma cortisol level, etc.), production variables (milk production and reproduction) and other factors related to hoof trimming.
