MENDES, A.S. et al. Measurement of locomotor problems and pad lesions in broilers. Arch. zootec. [online]. 2012, vol.61, n.234, pp.217-228. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922012000200006.

This study was conducted in UTFPR, Campus Dois Vizinhos-PR and divided into two experiments with 600 male broilers of the same lineage and origin. The objective of this study was to evaluate different methodologies for measurement of footpad and locomotors lesions in broilers and the effect of housing density on the incidence of these injuries. For the experiment the incidence of locomotor problems in a completely randomized design and factorial 3 x 3 x 2 (density x evaluators x methods of locomotor problems). For the experiment of footpad dermatitis, the birds were distributed in a completely randomized design and factorial 3 x 3 x 3 (density x evaluators x methods of footpad lesions), with four replicates. For the evaluation of each methodology, we used three different evaluators who were previously trained on the application of methods and without any interaction between them. The averages were compared by Tukey tests at 5% probability of error. The repeatability of the method was analyzed from scores measurements taken by evaluators. The intraclass correlation coefficient (ICC) was applied with a significant level of 5%. Density of housing affects the higher intensity of locomotor problems and foot pad dermatitis of the birds, increasing their development. In general, the methods were not available to be interpreted and applied.
