ABSTRACT This study mapped cattle carcass lesions and associated the isoline maps with the occurrence factors of these lesions. Isoline maps were drawn by common kriging. The associated occurrence factors were the layout of the boards in the crowding tub (CT), characteristics of the hauling truck (general state and the presence of loose and/or sharp boards), broken boards in the corral (BBC), type of road covered (TRC), and animal falls upon unloading at the slaughterhouse (FAUS). The BBC showed a […]

The objective of this study was to identify the pattern of deposition of feces by supplemented crossbred dairy cows after the lactation peak on cultivated areas under levels of intensification of the system and its effects on nitrogen cycling, with the aid of geostatistics, in the rainy period. Treatments were composed of two levels of nitrogen fertilization (equivalent to 400 and 800 kg N/ha/year) and two types of animals, according to the daily milk production. Geostatistical and descriptive analyses of […]

The objective of this study was to analyze variability, linear and spatial correlations of forage dry mass yield (FDM) and dry matter percentage (DM%) of Brachiaria decumbens with the bulk density (BD), gravimetric (GM) and volumetric (VM) moisture, mechanical resistance to penetration (RP) and organic matter content (OM), at depths 1 (0-0.10 m) and 2 (0.10-0.20 m), in a Red Latosol (Oxisol), in order to select an indicator of soil physical quality and identify possible causes of pasture degradation. The […]
