2. Feed Additives
•Feed additives are non-nutritive products used in minute quantities to improve
-Feed Quality
-Nutrient utilization
-Growth performance
•Feed additive can boost the results of quality feeds
•Most of the feed additive improve gut health

3. Benefits of Feed Additives
•Better nutrient absorption and utilization
•reduce the growth of intestinal pathogens
•Improve production performance
•Improve feed conversion efficiency
•Reduce stress
•Minimize the chances of disease
•Provide the feed with better quality
•Maximize profit

4. Feed Additives for Poultry
•Growth Promoters
•Toxin Binders
•Antioxidants
•Electrolytes
•Emulsifiers
•Feed preservatives
•Pellet binders
•Coccidiostates

5. Growth promoters
1.Antibiotic growth promoters
2.Natural growth promoters
•Prebiotics
•Probiotics
•Synbiotics
•Yeasts
•Organic Acids
•Herbal (Phytogenic) growth promoters
•Enzymes
•Vitamins and Minerals

7. Antibiotic Growth Promoters
•Used in animal feed since 1940s
•Antibiotic with low dose used to improve growth performance
•Good for growth but many demerits i.e.
-Drug Resistance
-Drug residues transfer to humans
-Transfer of drug resistant bacteria to humans
•AGP’s are banned in poultry production

8. Some of AGPs are,
•Lincomycin
•Enramycin
•Avilamycin
•Amoxicillin
•Colistin
•Neomycin
•Zinc bacitracin

10. Prebiotics, Probiotics, Synbiotics and
Yeasts
•Prebioticsare Non-living substances which promotes the growth of
probiotics
•Probioticsare the microbial culture which promote gut health through
competitive exclusion
•Prebiotics + Probiotics = Synbiotics
•Commonly used yeast as growth promoter is Saccharomyces cerevisiae

11. Prebiotics Probiotics
Fructooligosaccharide (FOS)
Mannanoligosaccharide (MOS)
Lactobacillus plantarum
Bacillus subtilis

13. Organic Acids
•Organic acids positively affect gut of bird
•Reduce pH of gut, pathogens and improve nutrient utilization
•Organic acids that can be used in poultry are
a.Citric acid
b.Butyric acid
c.Formic acid
d.Propionic acid
e.Lactic acid
f.Tartaric acid
g.Malic acid
h.Fumaricacid

15. Herbal growth promoters
•Derived from spices, herbs and essential oils
•Improve gut health and nutrient utilization
a.Turmeric
b.Black seed
c.Garlic
d.Ginger
e.Aloe vera
f.Neem
g.Fenugreek
h.Aniseed

17. Exogenous Enzymes
•Involved in all anabolic and catabolic pathways of digestion and
metabolism
•Major advance in poultry nutrition
•Plants contain some compounds that require exogenous enzymes
•Enzymes reduced the anti-nutrionaleffects of phytate, xylansand arabinoxylans
etc.
•Feed enzymes usually stable up to 95
0
F for short time

19. Toxin Binders
•Mycotoxins are great threat for humans and animals
•Aflatoxin, ochratoxin, DON, T2
•These reduce growth performance, immunity and cause pathological lesions
•Toxin binders bind the mycotoxin in intestine and excreted through feces
•Toxin binders reduce absorption and bioavailability of mycotoxins
•Famous toxin binders include, Zeolites, Bentonites, Aluminosilicates, HSCAS, Clay, Activated
charcoal, yeast, yeast cell wall

21. Antioxidants
•Antioxidants are used to prevent the oxidation of fats in the feed
•Butylated Hydroxyl Toluene (BHT)
•Butylated Hydroxyl Anisole (BHA)
•Ethoxyquene
•Vitamin E
•Se
•Vitamin C

22. Emulsifiers
•Emulsifiers assist fat digestibility
•Young chicks have limited fat digestion due to low bile production
•Poultry feed is usually supplemented with fats and oils
•Bile salts are natural emulsifiers
•Examples: soy-lecithin, milk derived casein, lysophatidylcholineor lysolecithin(lecithin),
bile salt, Glycerol polyethylene glycol ricinoleate(E 484), and Sodium Stearoyl-2-
Lactylate (SSL) etc.

23. Pellet Binders
•Used to improve pellet quality
•Reduce feed dust and help pellets better adhere
•Bentonite clay
•Lignin sulfate
•Attapulgiteclay

24. Intestinal health and Feed Additives
•Necrotic enteritis and Coccidiosis are the major intestinal issues
•Antibiotics are used to prevent enteritis i.e. Avilamycin, Lincomycin,
Enramycin, Zinc Bacitrainetc.
•Coccidiostates are used to prevent coccidiosis i.e. Nicarbazine,
Diclazuril, Maduramicin, Salinomycinetc.
