The effect of litter density, organic minerals and an extract of Yucca schidigera (MicroAid®) on the development of footpad dermatitis (FPD) in broiler chickens was evaluated. Four treatments were studied: Trt 1) traditional fattening program plus a litter density of 1 kg m-2, Trt 2) traditional fattening program (Trt 1) plus a litter density of 2 kg m-2, Trt 3) traditional fattening program plus a foot health program (40 ppm of Availa-Zn, 40 ppm of Availa-Mn and 125 ppm of MicroAid®) added to the diet, and Trt 4) combination of treatment 2 (Trt 2) and the foot health program implemented in treatment 3. Ross-line chickens were used. FPD was evaluated at day 45 of the fattening cycle using three scores (categories): 0=no lesions, 1=mild lesion and 2=severe lesion. Data were analysed using a generalized linear mixed model with multinomial response. Significant differences (P<0.05) among treatments were observed. The increase in litter density and the foot health program, on a separate basis, significantly reduced the percentage of chickens with a severe lesion to the footpad and increased the percentage of chickens with no lesions. The use of organic minerals (Availa-Zn and Availa-Mn at 40 ppm) and MicroAid® as supplements in the diet in conjunction with a litter density of 2 kg m-2 resulted in the greatest reduction in the incidence of FPD in broiler chickens (Trt 4).
