Nutritional performance of different soybean cultivars submitted to low temperature storage conditions

Abstract

Soybean ( Glycine max L. ) is the Brazilian agricultural crop that has grown the most in the last three decades and corresponds to 49% of the area planted in grains of the country. Increased productivity is associated with technological advances, management and efficiency of producers. Grain is an essential component in the manufacture of animal feed and with increasing use in human food is in rapid growth. The present work had the objective of evaluating the maintenance of the nutritional properties of conventional and transgenic soybean in a controlled and uncontrolled environment. The parameters used in the nutritional evaluation, before and after storage were water content; ashes; crude protein; crude fiber and oil content. The experimental design was completely randomized in subdivided plots, with three replications. The results showed that the controlled environment was effective in preserving the nutritional indexes of the product. The conventional cultivars also presented better performance when compared to the transgenic cultivar, if they were more suitable for their use as feed.
