Short communication: Diet digestibility measured from fecal samples and associations with phenotypic and genetic merit for milk yield and composition.

Abstract excerpt

Selection for improved feed utilization is of high interest globally but is limited by the high cost of obtaining feed intake for individual cows and relies on indirect measures of feed efficiency. Supplementing selection with mechanistic measures of feed use could make selection for feed utilization more direct and effective. The objectives of this study were to evaluate fecal sampling as a method of determining...
