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.

Three methods were compared in the estimate of lignin cell wall contents in different fractions of seven forage species. The methods for assaying lignin were: acid detergent lignin, permanganate lignin and acetyl bromide soluble lignin. The lignin extracted from the forage sample through the acetyl bromide reagent was employed as a reference standard for the spectrophotometric method. There was no agreement among the three methods; in general, the ABSL yielded higher values than the two other analytical procedures while the […]

The lignin extracted from the forages by the acetyl bromide reagent (acetyl bromide lignin – AcBrL) to be used as a reference standard for the quantitative spectrophotometric determination of lignin could not originate from intact plant because of interference of other substances, which absorb ultraviolet light at the same wavelength of lignin. It is then recommended that lignin extraction be performed in one of the following materials: cell wall itself (CW), neutral detergent fiber (NDF), or acid detergent fiber (ADF). […]
