Abstract

The correlation between dry matter (DM) content, electrical conductivity (EC) and ash content was found to be linear in grass and alfalfa during drying. While minerals in grass and alfalfa were very stable components during drying, their concentrations and EC increase accordingly; therefore, the EC value could serve as a measurement to determine DM content. Results indicated that EC measurement in grass and alfalfa during drying was simple, accurate, fast and easily repeatable, and could serve as an alternative method for DM determination.A correlação entre o conteúdo da matéria seca (MS), condutividade elétrica (CE) e o conteúdo de cinza revelaram-se lineares na grama e na alfalfa durante a secagem. Os minerais presentes na grama e na alfalfa demonstraram ser componentes muito estáveis durante a secagem. Desta forma as concentrações de minerais e a CE poderiam ser utilizadas como parametros para determinação da MS. Os resultados indicaram que a determinação da CE na grama e na alfalfa durante a secagem era simples, exata, rápida e facilmente repetitível, e poderia ser utilizado como um método alternativo para a determinação de MS.
