Mixing uniformity affects piglet, broiler performance

摘要

Properly mixed feed is required for optimal performance, but optimal mixing time differs among species.Mixing uniformity, as estimated by coefficient of variation (CV) of a specific nutrient or ingredient (usually chlorine from salt), is used to measure degree of dispersion of ingredients throughout a batch of feed. It is often recommended that a coefficient of variation less than 10 percent indicates appropriate mixing, but recent data suggest that up to 20 percent CV may be adequate for most practical diets. In general, mixing uniformity increases with mixing time.
