One of analytical techniques that enables precise chemical analyzes with speed, low cost and little sample manipulation is near-infrared spectroscopy - NIRS. The interest in NIR spectroscopy has grown remarkably and this technique has been recognized as a powerful tool for quantitative and qualitative analysis of chemical and physical parameters. Besides these features, the methodologies based on NIR spectroscopy have the following inherent properties: 1) allows simultaneous analysis of multi

Sugarcane is one of the most economical alternatives for off-season roughage feeding, which, whenever corrected, can become a feeding solution for animals with average production, even with the managerial difficulties of daily harvesting, regrowth handling, need for extra labor or specialized machinery, need to complete harvest within the same cycle, in addition to the risk of fire in the crop fields, all of which can be corrected. A correction alternative is sugarcane ensiling and nutritional e
