ANSC Feeds Practice Exam 2026 - Free Practice Questions and Study Guide

By-product feed refers to feed ingredients that are derived from the processing of other food products. This means that during the manufacture of certain food items, there are components that may not be utilized for human consumption but can still serve as valuable nutrition for livestock. For example, when grains are processed for human food, the leftover parts, such as bran or hulls, can be used as by-product feeds. These feeds are often rich in nutrients, making them an important and economical component of livestock diets.

The emphasis on by-products highlights their integral role in animal nutrition, as they often reduce waste and increase the efficiency of food production systems by recycling materials that might otherwise be discarded. This not only supports animal health but also promotes a more sustainable approach to food production. Other options do not accurately describe by-product feeds, as they focus on different sources or properties of feed that do not align with the definition and common understanding of by-product feeds.
