Quick Summary

By-product feeds in agriculture are materials derived from the processing of crops or animals for human consumption or other industrial uses. These by-products are then utilized as animal feed.

Examples of by-product feeds include:
* Cereal grain processing: Wheat bran, middlings, and germ meal from wheat milling; rice bran and hulls from rice polishing; and corn gluten feed, meal, and hominy feed from corn starch production.
* Fermentation industries: Brewers' grains and corn distillers' grains from beer and spirits production.
* Food processing: Bakery wastes, pineapple bran, and ensiled pineapple leaves.
* Animal processing: Meat and bonemeal, tankage, meat scraps, blood meal, poultry waste, and feather meal from abattoirs and meatpacking plants.
* Dairy industry: Dried skim milk, whey, and buttermilk.
* Fish processing: Various types of fish meals, which are rich in protein, calcium, and phosphorus.

These by-product feeds are an important part of animal nutrition, offering concentrated energy and valuable nutrients.1
