2. FEED ADDITIVES ,MOA,
CLASSIFICATION AND USES IN
RUMINANTS.
.

3. FEED ADDITIVES
 A compound added to the ration for supply
nutrients
 Health and performance of animals
 To improve the level of production
 better Efficiency
 average daily gain

4. CONT ……
 minimize the incidence of bloat
 Acidosis
 reduce liver abscesses
 control problems of foot rot
 control parasitic diseases

5. CLASSIFICATION
 Nutritive feed additives
 Vitamins
 Minerals
 Amino acid

6. NON NUTRITION FEED ADDITIVES
 Antibiotic
 Prebiotic
 Ionophore
 Chemobiotic

7. IMPORTANT GROWTH STIMULANTS
 Enzymes
 Chemobiotic
 PH regulator
 Feed flavor
 Hormones
 Prebiotic
 Probiotic

8. ANTIBIOTICS
 formation of bacterial cell
 causes the bursting of cell
 act on gram +ve and –ve bacteria

9. CONT..
 Bacitracin
 Streptomycin
 Virginiamycin
 Flavomycin

10. IONOPHORES
 transform the microbial fermentation
 increase the utilization of feed and gain
 Lasalocid and Monensin etc
 change the types of fatty acids
 increase capture of feed energy
 performance improves

11. PROBIOTICS
 Opposite of antibiotics
 have a +ve effect on the host
 detoxify the harmful metabolites
 helpful in improving nutrient availability
 Use as milk replacers
 increase the growth of beneficial microflora
 Decrease the growth of pathogenic bacteria

12. OLIGOSACCHARIDES
 Fermented in the intestine
 Nutrient source for lactic acid producing
bacteria
 Fermented by favorable bacteria
 Microbial number may be increased

13. YEAST CULTURES:
 Progress the…
 feed efficiency
 Feed gain
 Health
 Increased DMI
 pH of rumen
 nutrient digestibility

14. USES OF FEED ADDITIVE
 Greater milk production
 Increasing the protein and fat in milk
 Improve DMI
 Motivate VFA production
 Increase digestion
 Stabilize the rumen environment and ph

15. CONT..
 Improve growth
 Improve feed efficiency
 reduced heat stress

16. BUFFERS
 combination of acid and salt
 Decrease the rate of acidosis
 E.g Potassium carbonate
 And Magnesium oxide

17. MOA OF NSP
 influences on digesta viscosity
 also on the intestinal microflora
 located in the cell walls
 partial hydrolysis of pentosans and ß-glucans

18. MOULD INHIBITORS
 mixture of organic acids
 prevent the mould growth
 It inhibition the mould growth
 Use for preservation of feed compound
 avoidance of mycotoxin growth
 it have lengthy feed storage time

19. CATEGORIES OF FEED ADDITIVE
 Acids
 Acidity regulators
 Antifoaming agents
 Antioxidants
 Bulking agents
 Emulsifiers

20. CONT..
 Flavors
 Glazing agents
 Humectants
 Preservatives
 Stabilizers
