Estimates of the amount of variation (i.e., standard deviations and ranges) in nutrient composition of common feeds are readily available from some national feed testing labs; however, estimates of variation on feeds within a farm are needed to determine appropriate feed sampling and ration re-formulation schedules. We conducted a large national survey to determine within farm variation for some common feeds. On average, within farm variation for crude protein (CP) and neutral detergent fiber… CONTINUE READING
