The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

The objective of this experiment was the extraction of lignin and its use in the calibration curves to determine lignin concentration in vegetable plants. Among the analytical methods for measuring lignin concentration, there is the “acetyl bromide soluble lignin -ABSL” method, were solubilized lignin in 25% solution of acetyl bromide in glacial acetic acid is read at 280 nm. However, any spectrophotometric method requires a reliable standard to which optical density readings are compared; in this experiment, the standard was […]
