Abstract

This review examines key analytical methods for determining the nutritional value of forage and feedstuffs, focusing on the fibrous fraction's variability and its impact on animal nutrition. Traditional and modern techniques, including the widely used detergent system and enzymatic-gravimetric methods, are evaluated for their accuracy, reproducibility, and practicality. Despite improvements, challenges remain due to methodological variations and the high costs of advanced techniques. The review highlights the need for further research to enhance analytical methods, ensuring precise estimation of cell wall constituents for optimal diet formulation in animal production.
