  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.

  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.
