Most animal feed is from plants, but some manufacturers add ingredients to processed feeds that are of animal origin. The worldwide animal feed trade produced 1.245 billion tons of compound feed in 2022 according to an estimate by the International Feed Industry Federation, [ 1 ] with an annual growth rate of about 2%.
Animal feed is an important input to animal agriculture, and is frequently the main cost of the raising or keeping of animals. Farms typically try to reduce cost for this food, by growing their own, grazing animals, or supplementing expensive feeds with substitutes, such as food waste like spent grain from beer brewing .
A food-feed system is an integrated livestock-crop production system where crops grown on farms are harvested for human consumption and the crop-residues or by-products are used as feed for livestock.
Ether analogues of triglycerides: 1-alkyldiacyl-sn-glycerols (alkyldiacylglycerols) are found in significant proportions in marine animals. [5] Other ether lipids: a number of other lipids not belonging to any of the classes above contain the ether linkage. For example, seminolipid, a vital part of the testes and sperm cells, has a ether ...
Eucalyptol (also called cineole) is a monoterpenoid colorless liquid, and a bicyclic ether. [1] It has a fresh camphor-like odor and a spicy, cooling taste. [1] It is insoluble in water, but miscible with organic solvents. Eucalyptol makes up about 70–90% of eucalyptus oil.
A cyclic ether and high-boiling solvent (b.p. 101.1 °C). Tetrahydrofuran (THF) A cyclic ether, one of the most polar simple ethers that is used as a solvent. Anisole (methoxybenzene) An aryl ether and a major constituent of the essential oil of anise seed. Crown ethers: Cyclic polyethers that are used as phase transfer catalysts. Polyethylene ...
Humans use seaweeds nutritionally as food, industrially for animal feed and plant fertilizer, and ecologically to improve environmental conditions. [ 7 ] [ 6 ] [ 8 ] Seaweeds have been consumed by humans for centuries because they have excellent nutritional profiles, contain minerals, trace elements , amino acids , and vitamins , [ 7 ] and are ...
Maize is a major source of animal feed. As a grain crop, the dried kernels are used as feed. They are often kept on the cob for storage in a corn crib, or they may be shelled off for storage in a grain bin. When the grain is used for feed, the rest of the plant (the corn stover) can be used later as fodder, bedding (litter), or soil conditioner.
