Different lighting programs can be used to reduce damage on the pads. [...]Van Harn (2009) compared the influence of two light modes (constants and alternating) on appearance of damage to the pads. Increased physical activity of the chicken caused by regular changing of light and darkness in alternating lighting program and total duration of the photoperiod of 16 hours leads to an improvement in resistance broiler legs and the reduction of problems with the formation of foot lesions (Škrbić et al., 2009). The authors found a significantly higher percentage of difficult lesions in chickens fed by economic mixtures as a result of the increased moisture content of the sawdust due to poor digestibility and nutritional value of the economic mixture, which affected the viscosity of digest which reduced water absorption and increased water loss by excretion. A high level of crude protein leads to greater formation of uric acid in the liver and its renal excretion (De Jong et al., 2010, 2015), which results in poor quality the sawdust and increases the risk of formation the lesions on foot pads.
