| The main objective of "CedABio" was to estimate the environmental and socioeconomic benefits anticipated in the bovine farming systems adopting an organic production mode. Beyond some obvious advantages, the goal was to measure and ascertain the real contributions of a change to organic farming for the dairy and beef farms. To lead this assessment, strong and technically accessible indicators were selected, tested, and then looked for in 144 livestock farms, located in varied contexts to take into account territorial diversity. Half of the farms were in organic mode. Their results are compared with the other half producing in conventional mode, situated in the same zones, with similar structures. The results and the observations performed in this... |

| Australia in 1992 adopted the National Strategy for Ecologically Sustainable Development to ensure all future development occurs in a 'sustainable' manner. Measurement of the nation's sustainable development is currently conducted through the OECD Environmental Performance Review and various other ad-hoc indicators or measures have been proposed, such as greening the national accounts (Green Gross National Product) and the Genuine Progress Indicator. No one has identified a clear and precise way to either measure or model sustainable development in Australia. By trialing the implementation of inclusive wealth theory in Australia, this paper aims to identify and comment on the issues of measuring and modelling sustainable development as a stock measure in... |

| Using USDA’s Agricultural Resource Management Survey data, factors leading to the adoption of technology, management practices, and production systems by U.S. beef cow-calf producers are analyzed. Binary logit regression models are used to determine impacts of vertical integration; region of the U.S.; farm size, diversification, and tenure; and demographics on adoption decisions. Significant differences were found in adoption rates by region of the U.S., degree of vertical integration, and size of operation, suggesting the presence of economies of size and vertical economies of scope. Results also indicate high degrees of complementarity among technologies, management practices, and production systems. |

| Este trabajo analizó el desempeño de la cadena exportadora de manzana para consumo en fresco, en Uruguay, mediante el método de la matriz de análisis de políticas (MAP). Se trabajó con la variedad Royal Gala, una de las más exportadas localmente por su temprana maduración y su buena aceptación en mercados de valor, como el europeo. Se cuantificaron los efectos de las políticas públicas (impuestos, subsidios, cargas sociales) y las eventuales fallas de mercado que afectan los distintos eslabones, estimándose las potenciales transferencias de recursos, desde o hacia la cadena. Primero se computaron los ingresos y costos en los distintos eslabones considerados: producción, transporte, procesamiento y empaque. Se calcularon los beneficios privados y sociales... |

| ABSTRACT The present study was planned to evaluate the growth performance, morphometrics, physiological and behavioral response of Naked Neck chicken under different production systems and nutritional regimens. For this, a total of 900 Naked Neck chickens of 6-weeks of age were used; the birds were divided into 10 treatment groups consisting of 5 replicates of 18 birds each. A 2×5 factorial arrangement of treatment was employed under Completely Randomized Design. Treatments were consisted of two production systems (intensive and free range) and five nutritional regimens (100% commercial feed, 75% commercial feed +25% kitchen waste, 50% commercial feed +50% kitchen waste, 25% commercial feed +75% kitchen waste and 100% kitchen waste). Body weight, heartbeat... |

| The objective of this study was to evaluate the biometric and morphometric measures, regional composition, carcass characteristics and non-carcass components of Santa Inês lambs submitted to levels of corn replaced by cactus pear in the diet. It was used 45 Santa Ines non-castrated male lambs, with average initial live weight of 25.50 ± 0.48 kg as a completely randomized block design with five treatments (0; 25; 50; 70 and 100%) and nine replicates. There was an effect of the diet on slaughter weight, empty body weight, hot and cold carcass, cold carcass weight, shoulder weight and loin weight. Cactus pear can replace up to 75% of corn in diets for feedlot Santa Inês lambs, without compromising production, carcass characteristics and production of... |

| The objective was to evaluate elephant grass (Pennisetum purpureum Schum.) pastures, under the agroecological and conventional systems, as forage mass and stocking rate. In the agroecological system, the elephant grass was established in rows spaced by 3.0 m from each other. During the cool season ryegrass (Lolium multiflorum Lam.) was established between these rows, which allowed the development of spontaneous growth species during the warm season. In the conventional system the elephant grass was established singularly in rows spaced 1.4 m from each other. Organic and chemical fertilizers were applied at 150 kg of N/ha/year with in the pastures under agroecological and conventional systems, respectively. Lactating Holstein cows which received 5.0 kg/day... |

| Thirty-five feedlot lambs (without defined breed, aged between 5 and 7 months, with average live weight of 17.7±3.7 kg) were used in a completely randomized design to evaluate the effect of diets containing different genotypes of sorghum on morphometric measurements and qualitative characteristics of carcass and yields of primal cuts. The animals stayed in individual indoor pens for 42 days and slaughtered at an average weight of 26.24 kg. No significant differences were observed on morphometric measurements, hot (11.67 kg) and cold (11.39 kg) carcass weight, hot (44.46%) and cold (43.37%) carcass yields, biological yield and on cooling losses. There was also no significant effect of silages of different genotypes of sorghum on the weights and yields of... |

| Pushed by the Brazilian biodiesel policy, sunflower (Helianthus annuus L.) production is becoming increasingly regarded as an option to boost farmers' income, particularly under semi-arid conditions. Biodiesel related opportunities increase the demand for decision-making information at different levels, which could be met by simulation models. This study aimed to evaluate the performance of the crop model OILCROP-SUN to simulate sunflower development and growth under Brazilian conditions and to explore sunflower water- and nitrogen-limited, water-limited and potential yield and yield variability over an array of sowing dates in the northern region of the state of Minas Gerais, Brazil. For model calibration, an experiment was conducted in which two... |

| Abstract The objective of the present study was to characterize maize silage according to chemical composition, maize silage yield, as well as their predicted milk production. A search was made on studies related to maize silage yield, density, chemical composition (DM, CP, NDF, starch), and dry matter digestibility (DMD). In this study, 41 maize varieties from temperate regions and 101 maize varieties from tropical origin were analyzed. The net energy of lactation (NEL Mcal/kg DM), kilograms of milk per t of silage (kg of milk/t DM), and kilograms of milk per hectare of silage (kg of milk/ha) were determined. A cluster (CL) analysis was performed, and six CL of maize silage were obtained. The CL1 included digestibility for dry matter, crude protein,... |
