Feed additives are non-nutritive products added to rations to improve the efficiency of animal production via an improvement in intake, digestion, and/or metabolism efficiency, and/or the health of the animal.
Natural additives are chemical compounds extracted from plants, animals or minerals. Synthetic additives are not extracts, but are the result of a chemical or enzymatic reaction. They are either completely identical to a natural equivalent, or pure creations which do not exist in a natural state.
The main groups of food additives are antioxidants, colours, flavour enhancers, sweeteners, emulsifiers and stabilizers and preservatives. All additives are thoroughly assessed for safety before they are allowed to be used.
Of more than 3,000 substances used as food additives, salt, sugar, and corn syrup are by far the most widely used additives in food in the United States. For more information, go to Additives in Meat and Poultry Products.
There are many classes of feed additives, including: antibiotics and antimicrobials, anthelmintics (de-wormers), direct-fed microbials (probiotics), prebiotics, pellet binders, flavors, enzymes, growth and feed efficiency enhancers, supplemental nutrients, mold inhibitors and preservatives, and a beta-adrenergic ...
The diet of animals and humans contain a wide variety of additives. However, in poultry diets, these additives are primarily included to improve the efficiency of the bird's growth and/or laying capacity, prevent disease and improve feed utilisation.
SENSORY ADDITIVES are substances that improve or change the organoleptic properties of feed, or the visual characteristics of food derived from animals.
Use of Antibiotics in Animal Feed Currently, the following antibiotics are used in livestock and poultry feed: chlortetracycline, procaine penicillin, oxytetracycline, tylosin, bacitracin, neomycin sulfate, streptomycin, erythromycin, linomycin, oleandomycin, virginamycin, and bambermycins.
Feed additives are substances which are added in trace amounts to a diet or feed ingredient either a) to preserve its nutritional characteristics prior to feeding (ie. antioxidants and mould inhibitors), b) to facilitate ingredient dispersion or feed pelleting (ie.
