Use of a portable near-infrared spectrophotometer to predict nutrient composition of feces from feedlot Holstein cattle and its applicability for on-site research and industry use
Two studies were performed to investigate the ability of a portable near-infrared spectrophotometer (NIRS) for on-site analysis of nutrient components in feces from cattle. In trial 1 of study 1, growing dairy steers were fed diets containing either 86 or 90% concentrate. Regression values from a ca...
