Abstract - The objective of this work was to evaluate the efficiency of the stabilization process of swine manure in storage ponds regarding the presence and antibiotic resistance of pathogenic bacteria. The study was carried out in two trials in ten swine farms located in the municipality of Presidente Castello Branco, in the state of Santa Catarina, Brazil. In the first trial, the efficiency in reducing Escherichia coli (EC), non-E. coli coliforms, and Salmonella sp., as well as the resistance of isolates to antimicrobials, was investigated under recommended handling conditions. Sampling was done at three depths and two times. In the second trial, the concentration of total and fecal coliforms (EC) was evaluated under field handling conditions, when the manure was distributed on the field. Sampling depth does not influence the concentration of EC and Salmonella sp., and isolated bacteria are multi resistant to the evaluated antibiotics. Hydraulic retention time is determinant in reducing the population levels of the indicator agents. The obtained results are indicative that swine manure handling must be carried out according to sanitary standards, in order to minimize the propagation risk and antimicrobial resistance of pathogenic microorganisms.
Resumo - O objetivo deste trabalho foi avaliar a eficiência do processo de estabilização de dejetos suínos em lagoas de estabilização quanto à presença e à resistência a antibióticos de bactérias patogênicas. O estudo foi realizado em dois ensaios, em dez granjas de suínos localizadas no município de Presidente Castello Branco, no estado de Santa Catarina, Brasil. No primeiro ensaio, investigou-se a eficiência na redução de Escherichia coli (EC), coliformes não E. coli e Salmonella sp., bem como a resistência de isolados a antimicrobianos sob condições de manejo recomendadas. A amostragem foi realizada em três níveis de profundidade e dois tempos. No segundo ensaio, avaliou-se a concentração de coliformes totais e fecais (EC) em condições de manejo a campo, no momento da distribuição do dejeto na lavoura. A profundidade de amostragem não influencia a concentração de EC e Salmonella sp., e as bactérias isoladas são multirresistentes aos antibióticos avaliados. O tempo de retenção hidráulica é determinante na redução dos níveis populacionais dos agentes indicadores. Os resultados obtidos são indicativos de que o manejo dos dejetos suínos deve ser realizado de acordo com as normas sanitárias, para minimizar o risco de propagação e a resistência antimicrobiana de microrganismos patogênicos.

The corn biomass and nutrient dynamics may be altered when it is intercropped with Brachiaria (syn. Urochloa spp.). The present study aimed to investigate the dynamics of biomass, nitrogen (N), phosphorus (P) and potassium (K) for farming systems that produce corn intercropped with Brachiaria species. Field experiments were performed during the season and off-season, in a split-plot design. The main plots were composed of Brachiaria species (B. brizantha, B. ruziziensis and B. Convert) intercropped with corn, in addition to corn monocropping. The subplots consisted of three forage sampling periods, ranging from 0 to 60 days after the corn harvest. The intercropping arrangements did not affect the corn grain yield, nutrient accumulation and partitioning, relatively to the corn monocropping. After the grain harvest, B. brizantha achieved the greater biomass accumulation rate in both the season (69 kg ha-1 day-1) and off-season (17 kg ha-1 day-1). The nutrient accumulation ranged widely between the Brachiaria species and planting seasons: 0.2-1.2 kg ha-1 day-1 for N; 0.01-0.07 kg ha-1 day-1 for P; and 0.13-0.8 kg ha-1 day-1 for K. However, the greatest nutrient accumulation was found for B. brizantha, followed by B. ruziziensis and then B. Convert. In the short-term, corn intercropped with Brachiaria in the season showed the largest effect on the nutrient cycling and biomass yield. The intercropping between corn and B. brizantha in the season was the best way to enhance the biomass yield and the N, P and K cycling.
