Understanding how nonstructural carbohydrates fluctuate in pastures and being able to quantify them is an essential component in successfully managing grazing animals that may require high or low nonstructural carbohydrate diets. The objectives of this study were 1) to evaluate the effects of genotype, management, and environment on water-soluble carbohydrates (WSC) and ethanol-soluble carbohydrates (ESC) in cool-season grass pastures in central Kentucky, and 2) to develop near-infrared reflectance spectroscopy (NIRS) equations to predict WSC and ESC in cool-season grasses. Ten cool-season grass cultivars consisting of Kentucky bluegrass, tall fescue, orchardgrass and perennial ryegrass were sampled in the morning and afternoon …
