“…Tal fato pode vir a gerar prejuízos financeiros aos pecuaristas, uma vez que ocorre elevação do preço internacional do milho, motivado pela produção de bicombustível. Atualmente os EUA destinam 40% do milho produzido para produção de bicombustíveis (Wilkinson, 2010), alterando o preço internacional das commodities.…”

Silagem de híbridos de sorgo associado a percentagens de concentrado no desempenho de novilhos RESUMOAvaliou-se o desempenho de novilhos alimentados em confinamento com silagem de híbridos de sorgo forrageiro e de duplo propósito associado a níveis de concentrado. Foram utilizados 60 novilhos, com idade inicial de 20 meses e peso corporal inicial de 322,45±5,58kg, distribuídos inteiramente ao acaso, nos seguintes tratamentos: três porcentagens de concentrado e dois tipos de silagem de sorgo. Foi verificada interação tipo de silagem versus porcentagem concentrado para consumo de matéria seca e ganho de peso médio diário, os quais aumentaram com o aumento de concentrado na dieta com silagem de sorgo forrageiro, mas não com silagem de sorgo duplo propósito. Os novilhos alimentados com silagem de sorgo forrageiro consumiram menos energia digestível (27,89Mcal/dia -1 ) que aqueles alimentados com silagem de sorgo duplo propósito (31,42Mcal/dia -1 ). A conversão alimentar média não foi alterada pelo tipo de silagem utilizada. O aumento da porcentagem de concentrado em dietas com volumoso de menor qualidade aumenta a eficiência biológica de bovinos confinados.Palavras-chave: bovino de corte, ganho de peso, consumo, sorgo forrageiro, sorgo duplo propósito ABSTRACT

Abstract:The understanding of spatial dependence and distribution of agricultural production factors is a key issue for the territorial planning and regional development. This study evaluates the spatial-temporal dynamics of bean crops in Brazil over the period 1990-2013. Common bean (Phaseolus vulgaris L.) is one of the staple foods for the Brazilian population, with nationwide production and cultivated mostly by family farmers. The analyzed variables of this crop included harvested area, produced quantity, and average crop yield. We investigated spatial autocorrelations using the Global and Local Moran Index. The global spatial autocorrelation statistics demonstrated a general spatial dependence of bean production over Brazil, while the local spatial autocorrelation statistics detect statistically significant zones of high and low bean-production attributes. Maps of growth and acceleration rate of the variables were constructed, showing the areas that increased, decreased, or stagnated during the time series. The results showed a considerable reduction of the bean harvested area, but there were significant increases in produced quantity and average crop yield. Results showed distinct and significant patterns of bean-production variables in Brazilian territory over the different years. Regional differences and peculiarities are evident, emphasizing the need for directing investments to agricultural research and public policy.

“…Beef cattle production in Brazil has grown exponentially in recent decades, mainly through advancing agricultural frontiers and technology use (WILKINSON, 2010). Rio Grande Sul (RS) state, on the other hand, has been losing markets compared with states from Northern and Central-West regions of the country.…”

The aim of this experiment was to identify improvement demands for farms with different levels of competitiveness in the west of Rio Grande do Sul state, Brazil. A total of 63 owners of large farms were interviewed (farms with an area greater than 900ha) by applying a semi-structured questionnaire, guided by four drivers: technology (TEC), management (MAN), market relations (MR) and the institutional environment (IE
