Chemical composition of Andropogon gayanus cv. planaltina predicted through nirs and analyzed through wet chemistry

Abstract

Precision Animal Nutrition is an integrated, information-based system for optimizing nutrient supply and demand for animals to achieve a desired performance, profitability, product characteristics and environmental results (González et al., 2018). This requires frequently assessing the composition of the feed provided to animals, to ensure that the nutrient composition of the diet digitally formulated by a nutritionist is as close as possible to the diet provided. St-Pierre and Cobanov (2007) suggest that the chemical composition of the feed provided to large herds should be assessed every four days for better ration adjustments and cost reduction
