Nicarbazin is an anticoccidial used in poultry production. Its residue of concern left in chicken meat is 4,40 -dinitrocarbanilide (DNC) whose content can be reduced through meat thermal processing. Thermal analysis techniques can be considered to elucidate how DNC degradation proceeds. This study aimed to investigate the thermal behavior of DNC using TG-DSC-MS and Py-GC-MS. TG-DSC-MS data showed that DNC decomposition occurs in a single step (252-280 C) as an endothermic event (DH of 670 J g-1). Fragments detected at m/z 43, 44 and 65 indicated the release of isocyanic acid, carbon dioxide and 4-nitroaniline as breakdown products. In addition, Py-GC-MS analysis confirmed that DNC is thermally degraded above 250 C generating 4-nitrophenyl isocyanate and 4-nitroaniline as the major pyrolysis products. Findings obtained from thermal analysis herein are useful to better comprehend the DNC disappearance after submitting chicken meat to heat processing. |

Phosphate fertilization has increased sorghum yield, but few studies are available on sorghum production and efficient fertilizer management related to liming and phosphorus (P) sources. This work evaluates production, dry matter partitioning and agronomic efficiency (AEI) in successive sorghum cycles after application of limestone and combinations of phosphorus sources. Two cycles were conducted in sequence in the same experimental field, in a 2 x 6 factorial scheme, corresponding to soil with or without liming and six combinations of P2O5 sources: control (0 kg ha-1 P2O5), 100% Itafós natural phosphate (NP), 75% NP + 25% single superphosphate (SS), 50% NP + 50% SS, 25% NP + 75% SS and 100% SS. Pots with capacity for 8 dm3 were used in a randomized block design with four replicates. The first cycle, conducted in the summer/autumn season, reached the highest dry matter production and P accumulation in treatments with higher SS proportions, leading to higher AEI. Subsequently, in the second cycle, conducted considering only the residual phosphate fertilization of the first cycle, highest dry matter production and AEI were obtained in the treatment with 100% or higher proportions of natural phosphate in the presence of liming, most likely due to the gradual release of P. |
