2. Feed Additives
• Feed additives are non-nutritiveproducts used in minutequantitiesto improve
- Feed Quality
- Nutrientutilization
- Growth performance
• Feed additive can boost theresults of quality feeds
• Most of the feedadditive improve gut health

3. Benefits of Feed Additives
• Better nutrientabsorptionand utilization
• reduce the growth of intestinal pathogens
• Improve productionperformance
• Improve feed conversionefficiency
• Reduce stress
• Minimize the chancesof disease
• Provide the feed withbetter quality
• Maximizeprofit

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

5. Growth promoters
1. Antibioticgrowth 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 animalfeed since 1940s
•Antibioticwithlow dose used to improve growth performance
•Good for growth butmany demerits i.e.
- Drug Resistance
- Drug residuestransferto humans
- Transfer of drug resistantbacteriato humans
•AGP’s are bannedin poultry production

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

10. Prebiotics, Probiotics, Synbiotics and
Yeasts
•Prebiotics are Non-livingsubstances which promotes the growth of
probiotics
•Probiotics are the microbialculture which promotegut health through
competitive exclusion
•Prebiotics + Probiotics =Synbiotics
•Commonlyused yeast as growth promoter is Saccharomycescerevisiae

11. Prebiotics Probiotics
Fructooligosaccharide(FOS)
Mannanoligosaccharide(MOS)
Lactobacillusplantarum
Bacillussubtilis

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. Tartaricacid
g. Malicacid
h. Fumaric acid

15. Herbal growth promoters
• Derived from spices, herbs and essentialoils
• Improve gut health and nutrient utilization
a. Turmeric
b. Blackseed
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
•Majoradvance in poultrynutrition
•Plantscontain some compoundsthat require exogenous enzymes
•Enzymes reduced the anti-nutrionaleffectsof phytate, xylansandarabinoxylans
etc.
•Feed enzymes usuallystable up to950F for short time

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

21. Antioxidants
• Antioxidantsare used to prevent the oxidationof fatsin the feed
• ButylatedHydroxylToluene (BHT)
• ButylatedHydroxyl Anisole(BHA)
• Ethoxyquene
• VitaminE
• Se
• VitaminC

22. Emulsifiers
• Emulsifiersassist fatdigestibility
• Young chicks havelimited fatdigestion due tolow bile production
• Poultry feed is usuallysupplemented withfats and oils
• Bile salts are naturalemulsifiers
• Examples: soy-lecithin, milkderived casein, lysophatidylcholine or lysolecithin (lecithin),
bile salt, Glycerol polyethylene glycol ricinoleate (E 484), and Sodium Stearoyl-2-
Lactylate (SSL) etc.

23. Pellet Binders
•Used toimprovepellet quality
•Reducefeeddust and helppelletsbetteradhere
•Bentoniteclay
•Ligninsulfate
•Attapulgiteclay

24. Intestinal health and Feed Additives
• Necrotic enteritis andCoccidiosisare the major intestinal issues
• Antibiotics areused toprevent enteritisi.e. Avilamycin,Lincomycin,
Enramycin, ZincBacitrainetc.
• Coccidiostatesare used to prevent coccidiosisi.e. Nicarbazine,
Diclazuril,Maduramicin,Salinomycinetc.
