FEED ADDITIVES AND SUPPLEMENTS Flashcards
They are made of organic acid or mixture of organic acids. When
incorporated in the ration, they exert their effect on the gastrointestinal environment by lowering the stomach pH. Low stomach pH prevents the growth and proliferation of pathogenic microorganisms, thus, promoting better feed efficiency.
Acidifiers or Acidulants
examples of acidifiers
phosphoric acid, citric acid, lactic acid, fumaric acid and acetic acid
These are chemical products produced by microorganisms, which are added in the mixed feed at subtherapeutic level. These materials may increase growth rate and feed conversion in animals, but are potentially
harmful when improperly used.
Antibiotics
Antibiotics examples
aureomycin, streptomycin, erythromycin, neomycin, virginiamycin, tylosin and
chlortetracycline
These agents are used to improve the flowability of grains and feeds by preventing feedstuffs from adhering to surfaces, on the inside walls of silos, bins, conveying systems and mixers.
Anticaking Agents
These are used in the prevention and treatment of malaria which include phyrimethamine and chloroquin diphosphate.
Antimalarials
These are chemical preservatives added to the feeds to protect them from decomposition by microorganisms. The most common is propionic acid or its
salts, calcium and sodium propionate. Other organic acids that can inhibit mold growth are formic acid, sorbic acid, fumaric acid and citric acid.
Antimolds
These are used to prevent rancidity in feeds. Feeds containing 12% or more moisture and feeds containing fat or oil should be added with anti oxidant.
Antioxidants
The commonly used antioxidants
butylated hydroxytoluene (BHT),
santoquin, butylated hydroxy anisole (BHA), propyl gallate, ethoxyquin, calcium carbonate, phosphoric acid and citric acid.
These are administered to prevent and control coccidiosis.
Coccidiostats
Examples of coccidiostats
alkomide, amprolium, clopidol, robenedine, maduramycin, narasin and salinomycin.
These are used against internal parasites of the animals.
Dewormers
Examples of dewormers
flubendazole, tetramizole, oxfendazole, thiabendazole,
mebendazole and piperazine.
These are protein molecules that have the ability to catalyze biochemical reactions.
Enzymes
Feed flavors induce feed intake particularly for piglets. Using feed flavors in mixed feed may disguise the presence of unpalatable ingredients
Flavorings
These are agents added to improve the texture and firmness of pelleted feeds.
Pellet Binders
Pellet binders examples
gelatin extract derivatives, calcium lignosulphonate and galactomannan gum.
These are chemical agents added to enhance coloration and pigmentation of the skin or of the egg yolk in poultry.
Pigmenters
Also known as live microbial supplements, these are beneficial
microorganisms (mainly lactic acid producing bacteria and yeast combinations) added to rations to improve the intestinal microbial balance of the animal.
Probiotics
Examples of microorganisms
Lactobacillus sp. and Bifido bacterium sp.
These are used to increase lean-muscle and reduce fat deposition in carcasses when added in the diet during the finishing period.
Repartitioning Agents
Repartitioning Agents examples
chromium and hormones.
These are chemical agents that facilitate uniform dispersion of molecules in feeds or feed mixtures.
Surfactants
These are used for detoxification of mycotoxin- contaminated feeds and raw materials by either chelating the mycotoxin or by blocking the effect of mycotoxin at the digestive tract of animals that ingested the contaminated feeds.
