Nutrition factors are considered to be very important for incidence of foot-pad dermatitis through the effect on the quality of litter. Objective of this study was to investigate the effect of the use of two feeding programs for broilers available on the market and declared in the nutritional/economical sense as standard and economical, on quality of litter, incidence of leg dermatitis (foot-pad and hock burns) and production performance. Trial was carried out on 500 one day old chickens of Hubbard genotype, in two treatments and five replicates. Chopped straw was used as litter. During the trial, the mortality and food consumption were monitored, and at the end of trial the body mass was controlled, as well as the incidence of foot-pad and hock burns and their severity were evaluated and quality of litter analysed. Research results indicate significant effect of the diets from the aspect of broiler welfare and productivity. Application of the feeding program declared in the nutritional/economical sense as economical resulted in higher content of litter moisture, significantly higher frequency of incidence of the most severe forms of foot-pad dermatitis and significantly lower broiler performance.
