| O presente trabalho avaliou o efeito da adubação orgânica na produção total de batata-doce, por meio de um experimento realizado no período de julho a novembro de 2007, na Estação Experimental de Lagoa Seca, PB, Brasil. O delineamento experimental foi em blocos casualizados com cinco tratamentos (0, 3, 6, 9 e 12 t ha-1 de cama-de-aviário), em quatro repetições. A parcela foi composta por quatro leiras de 3,6 m de comprimento, espaçados de 0,80 m entre leiras e de 0,30 m entre plantas, sendo colhidas as duas fileiras centrais. As variáveis estudadas foram: produção total, raízes de tamanho graúdas e miúdas de batata-doce. A produção de raízes graúdas, miúdas e total por planta (14,20; 3,84 e 18,03 t ha-1) de batata-doce responderam de forma linear e... |

| Poultry litter (PL) is an organic matter source used as soil amendment. Besides its important nutrient content, it is a cheap alternative to conventional fertilizers in crop production. The efficient use of PL also helps reduce the environmental problems normally associated with its disposal near poultry production farms. This article reports the relative effects of PL and conventional fertilizers on the availability of soil N, P and K, dry matter (DM) production and total nutrient content in silage corn (Zea mays L.). The field experiment was carried out in a soil derived from volcanic ash (Tipic Melanoxerands) of Central South Chile. Corn was grown for three seasons (2002-2005) and PL and conventional fertilizers were applied in the first two years. The... |

| Con el objetivo de evaluar las características químicas de ensilados de pencas de nopal tunero y excretas pecuarias (pollinaza y estiércol bovino), se realizaron 2 experimentos con arreglos factoriales de tratamientos 4 x 4 en diseños experimentales completamente al azar; las unidades experimentales fueron 64 microensilados (16 tratamientos con 4 repeticiones), para cada experimento; con 6 kg de una mezcla compuesta con pencas de nopal, rastrojo de maíz molido, excretas pecuarias y melaza; ensilados en 4 tiempos: 0, 30 ,60 y 90 días (Factor A), con 4 concentraciones de excretas pecuarias: 0, 20, 30 y 50% (Factor B). Al incrementar el tiempo de ensilaje, aumentaron (P < 0.0001) la PC, carbohidratos no fibrosos (CNF), cenizas (C), EM (Mcal/kg), ácido... |

| Con el objetivo de determinar el tiempo de fermentación en estado sólido (FES) anaerobio de una mezcla de pollinaza, melaza y Vitafert que actué sobre poblaciones de enterobacterias indeseables y mejore las características de indicadores nutricionales, se estudiaron ocho tiempos de FES (0, 5, 10, 15, 20, 25, 30, 40 días), en un diseño completamente al azar con 3 repeticiones por tratamiento. Echerichia coli desapareció en el día 10 de FES. El pH, contenido de bacterias aeróbicas, fibra detergente neutro (FDN), y hemicelulosa, fue menor, con el transcurso de la fermentación, los menores valores se encontraron a partir del día 25 de FES. El proceso de fermentación incrementó el contenido de proteína cruda (PC), proteína verdadera (PV), acido láctico,... |

| Abstract: The objective of this work was to evaluate soil chemical attributes, leaf nitrogen content, and corn and wheat yields under a no-tillage system in response to the application of organic, organomineral, and mineral fertilizers with or without urease and nitrification inhibitors. The experiment was carried out on the field, with one wheat and two corn crops, on a Rhodic Kandiudox, in a randomized complete block design with six replicates. The evaluated treatments were: control, without fertilization; O, poultry litter as an organic fertilizer; O+I, poultry litter and inhibitors; OM, organomineral fertilizer; OM+I, organomineral fertilizer and inhibitors; U, urea as a mineral fertilizer; and U+I, super urea with the urease inhibitor alone. The use... |

| The aim of this study was to evaluate the performance, tibial density and mineral content, Na, K ,and Cl serum levels, and dry matter content of the litter of broilers fed diets with different levels of dietary electrolyte balances. Two experiments were carried out: during the starter phase (7 to 21 days of age, 960 broilers) and during the growe phase (22 to 38 days of age, 816 broilers). In both experiments, a completely randomized design with four treatments based on dietary electrolyte balance values (200, 240, 280 and 320 mEq/kg of diet) with four replicates was applied. Birds and diets were weighed when birds were seven, 14 and 21 days of age in the first experiment, and 22 and 38 days of age in the second experiment in order to determine weight... |

| ABSTRACT To study the antimicrobial and uric acid-preserving activity of pine bark tannin on poultry litter composting, antibiotic-free wood chip-based poultry litter was distributed (11 g) to 50-mL conical centrifuge tubes and immediately amended with 1.3 mL0.4 M sodium phosphate buffer (control) or with 1.3 mL condensed tannins from pine bark (Pinus palustris; 9 % tannin wt/vol in water). All tubes (n = 3 tubes/treatment) were inoculated with a novobiocin and naladixic acid-resistant Salmo-nella typhimurium (STNN) to achieve 3.0 log10 CFU/g and incubated at 37oC for 3 days to simulate an initial compost period. Wildtype E. coli and the challenge STNN strain as well as concentrations of ammonia, uric acid and urea were measured on days 0 and 3. Pine bark... |

| ABSTRACT Housing environment is essential to achieve good broiler performance and to prevent diseases, including footpad dermatitis (FPD). The objective of this study was to determine the incidence of footpad dermatitis in broilers chickens according to housing type. The study was carried out with broilers reared for 5, 12, 19, 29 and 40 days. Four houses were used in this observational study. House 1 (A1) had positive pressure and reused litter; house 2 (A2) had positive pressure and new litter (sawdust); house 3 (A3) had positive pressure and new litter (rice husks); and house 4 (A4) had negative pressure and reused litter. During the entire experiment, air environmental and litter surface temperatures, and litter compaction were recorded. Pododermatitis... |
