Fragments with vibrant colors and attractive textures in poultry house litter may be consumed considering that the confinement environment does not offer many opportunities for the development of the birdss natural behavior. Control and quality programs aiming to reduce and to eliminate the consumption of materials from the construction of sheds have been implanted. However, it is necessary to develop studies for a better understanding of the birds ingestive behavior and the consequences for their health, welfare and productivity. The goal of this study was to evaluate the ingestive behavior of broilers exposed to metal, wood, glass and plastic fragments at different concentrations and sizes added to the poultry house litter and the integrity of the gastrointestinal tract of broilers. A total of 360 birds were distributed in a completely randomized design over a 2x3 factorial scheme (2 fragment sizes: 2 to 7 mm and 5 to 8 mm and 3 concentrations: 0.1, 0.5 and 1%), totaling 6 treatments and 5 replicates. The fragments used were glass, wood, metal and plastic, in respective concentrations and sizes, distributed in the poultry house litter. The supply of fragments or the accidental occurrence of similar fragments to which were analyzed in this study concerning the poultry house litter, with different sizes, colors and textures does not compromise the integrity of the mucosa of the gastrointestinal tract and the welfare of the birds.(AU)
