Present day domesticated animals and poultry generation has accomplished amazing  picks up in the proficient and temperate generation of high caliber and safe creature items and side-effects. Moreover, the general execution of domesticated animals can be expanded by enhancing supplements use, well-being status, fruitfulness and productivity of creation. The utilization of nourish added substances has been an essential part of accomplishing effective animals creation. Bolster added substances are non-nutritive substances, arrangements and smaller scale creatures that are added to creature nourish to enhance gainful, reproductive and well-being exhibitions. Any substance is considered as a nourish added substance when, not having an immediate usage as supplement, is incorporated at an ideal fixation in eating routine to apply a positive activity over the creature well-being status or the dietary supplement use. 



Hutjens (1991) characterized feed additives as a gathering of substances that can cause a coveted creature reaction in a non-supplement part, for example, pH move, development, or metabolic modifier. Feed additives are added intentionally to creature sustain which may positively impacts qualities of the creature sustain, encourage admission, gastrointestinal vegetation, absorbability of the creature sustains, creature generation, well-being, richness and attributes of creature items. In view of their synthetic nature as dynamic standards, added substances are for the most part incorporated into little extents in slim proportions.

Worldwide monetary weights have driven a propensity of the animals generation to deliver more items per unit cost. This has prompted changes to creature's condition like nourishing, lodging and malady control. Nature of encourage nourishment is affected by the substance as well as by some different angles, for example, nourish introduction, cleanliness, hostile to nutritious variables, edibility and acceptability.

Feed additives give a component by which such dietary lacks can be tended to and furthermore benefits not just connected with the nourishment and in this way the development rate of the creature concerned, yet in addition its wellbeing and welfare.

Antimicrobial development promoters are normally bolstered to creatures to anticipate malady what's more, metabolic clutters, and in addition enhance nourish proficiency. Be that as it may, in later a long time, open worry about the potential for anti-infection safe strains of microorganisms, the look for other options to supplant anti-infection agents development promoters has increased expanding enthusiasm for creature sustenance. The utilization of phytogenic bolster added substances has picked up energy for their potential part as common choices to anti-infection development promoters in creature nourishment. Contrasted and engineered anti-infection agents or inorganic chemicals, these plant-inferred items have demonstrated to be characteristic, less poisonous, buildup free, and are believed to be perfect nourish added substances in nourishment creature generation. There are an extensive number of phytogenic nourish added substances which have cancer prevention agent, antibacterial, anticoccidial, antiparasitic and against provocative impact.

Types of feed additive
Common feed additives used in livestock and poultry diets include:
- Antimicrobials,
- Antioxidants,
- Enzymes,
- Probiotics,
- Prebiotics,
- Organic acids,
- Coccidiostats,
- Mycotoxin binders,
- Immunomodulators,
- Hormones,
- Emulsifiers,
- Pellet binders,
- Phytogenic herbs,
- Essential oils and
- Metabolic modifiers.

Broadly all of these are classified under four broad categories:

Sensory Additives – these stimulate an animals appetite so that they naturally want to eat more.

Nutritional Additives – these provide a particular nutrient that may be deficient in an animal’s diet.

Zootechnical Additive – these improve the overall nutritional value of an animal’s diet through additives in the feed.

Coccidiostats and Histomonostats – these are feed additives which are antibiotics, intended to kill or inhibit protozoa (bacteria/micro-organisms). However, these have been replaced by probiotics and prebiotics.

Although additives have been developed over the years for most species of livestock, the major uses today are with growing and finishing beef cattle, swine and poultry. Feed additives are gaining importance due to various functions such as growth promotion, controlling infectious diseases and enhancement of feed digestibility in animals. The animal feed additives market is growing at a steady pace and the market is to grow in the future due to the increasing demand for meat and meat products around the globe.
