Effect of different litter materials on growth performance, the gait score and footpad dermatitis, carcass parameters, meat quality, and microbial load of litter in broiler chickens.

In the current study, the microbial load of litter materials, growth performance, the gait score and footpad dermatitis, carcass characteristics, and meat quality of broilers reared on different litter materials were investigated. After hatching and sex determination, the chicks were allocated to 3 different experimental groups with each having 8 replications. The chicks were reared on thick sawdust, fine sawdust, or rice hull litter materials.

Utilizing Piezo Acoustic Sensors for the Identification of Surface Roughness and Textures.

This study examines surface roughness measurements via piezo acoustic disks and appropriate signal processing. Surface roughness is one characteristic of surface texture that can have various irregularities inherent to manufacturing methods. The surface roughness parameters and corresponding surface profiles are acquired by a stylus profilometer.
