Business Intelligence with Data Warehouse technologies are known in the literature as solutions that allow access to business data dynamically and analytical operations on them. Scientific literature lacks works that investigate the current use of these technologies in the agrarian sector, a...

The paraoxonases types 1, 2 and 3 (PON1, PON2 and PON3, respectively) are enzymes that degrade lipid peroxides, preventing oxidative damages relevant for male reproductive function. This study determined the expression of those three paraoxonases in reproductive tissues of bulls and evaluate...

Objective: The objective was to estimate economic values for production traits in a full life cycle system using a bio-economic model with Angus purebred and a terminal crossbreeding system with Nelore sires mated to Angus dams. Study Description: Phenotypic performance data were collec...

The objective of this study was to evaluate nonlinear statistical models to predict eucalyptus taper in a crop-livestock-forest integration system (ICLF). The data were obtained in an experimental area of ICLF implanted by the Brazilian company of Agricultural Research (EMBRAPA- Agrosilvipastoral...

Despite the socioeconomic importance for the Amazon, knowledge about the factors that influence the production of Brazil nuts is still incipient. In this paper we evaluate the influence of precipitation and soil texture, flood and depth on seed production. The data were collected i...

Nonparametric frontier estimation assesses relative efficiency of production units. The method with a larger scope in the literature is Data Envelopment Analysis (DEA). Efficiency analysis evaluated by DEA demands special attention when selecting the variables of the model. This paper incorporate...

A raça Brangus, desenvolvida a partir da união da rusticidade de animais de raças zebuínas (resistência a parasitas, tolerância ao calor e habilidade materna) com as vantagens da raça Angus (qualidade da carne, precocidade sexual e docilidade), vem apresentando bons índices de produtivi...

Apesar da boa aceitação e utilização de animais da raça Brangus nos mais diversos sistemas de produção, os programas de melhoramento animal que avaliam esses rebanhos no Brasil apresentam uma evidente deficiência na formulação dos índices de seleção.

The usage of cover crops is an adopted cultural measure that shows positive effects when associated with the no-till system and weed management. During the cycle of the plants there might be competition within them for water, solar radiation and nutrients and effects of allelo...
