The presentation discusses the role of non-starch polysaccharides (NSPs) in poultry feeding, highlighting their impact on feeding strategies and cost management in poultry production. NSPs can be beneficial or detrimental depending on their levels, and the document classifies NSPs based on their chemical composition and solubility. It emphasizes the importance of utilizing enzymes like xylanase to mitigate the negative effects of NSPs and improve nutrient absorption, ultimately enhancing profitability in poultry farming.

(NSPs)
in Poultry feeding

2. NSPs in Poultry feeding – Why??
Feeding Stratigies: Most crucial in any livestock
enterprise
#Feed in poultry accounts for 60-70% of total rearing
cost
Major constraint in poultry feeding- Increaing prices
of Conventional feedstuffs
Use of Non conventional feeds : INCREASES PROFIT
but contains high amount of NSPs

3. NSPs when low – BENEFICIAL
NSPs when high - DETRIMENTAL
Utilization of NSPs
Mitigating ANF property
Efficient conventional non
conventional feeds utilization
REDUCE FEED COST
“Increases Returns”

4. What are Non starch
polysaacharides??Polymeric carbohydrates
Differ in composition and structure from starch
-(Morgan Et al. ,1995)
Possess cross linking among themselves thus not
digested in gut
hey include cellulose pectins gums glucans mucila
inuline and chitin (exclude lignin)”
- Trowell, 1985

5. Classification
1. Chemically,
a.Cellulose- beta 1,4 glycocidic linked D- glucose units
b.Non cellulose polysaccharides – Hemicellulose
includes Arabinoxylans(Pentosans) beta-glucans
fructans mannans
-(Neurkon Et al. ,1967)
c.Pectin polymers- Polygalcturonic acid subsituted
with Arabinan Galactan Arabinogalactan

6. Arabinoxylan

7. 2.On the basis of solubility, (Sasaki Et al.)
a.Water sloluble / Viscous NSPs
b.Insoluble / Non viscous NSPs
On basis of above classification cereals are classified into
a.Viscous cereals : Rye Wheat Barley Oat Triticale
b.Non viscous cereals: Corn Sorghum Rice Millet

8. Soluble or viscous NSPs and its
effect in Poultry1.On biological hydrolysis it increases viscosity of digesta
Reducing passage rate of digesta digestion thus of other
nutrients reduced
2.Modification of gut physiology- Enlargement
-decreases enzyme substrate interaction
-decreases nutrient absorbtion
3.Reduce body cholesterol : Lean meat production

9. Soluble or Non-viscous NSPs and its effect in P
1.Being insoluble – Increses passage rate of digesta
- Increses digestion of starch
# Above property attributed due to accumulation of
insoluble NSPs in Gizzard---- (Minganchoct, University of
New England)
2.Encapsulte other nutrients lowering overall digestion
3.Cause pathogenesis of gut mucosa – Increased
susceptibility to 2⁰ bacterial infection
4. Wet litter conditions

10. Poultry Feed ingredients and
NSPs1.25% of poultry rations constitute NSPs
2.Soyabean has divesrse range of NSPs
3.Corn Wheat Barley Rye contains mainly Arabinoxylan
4.Rice bran –Arabinoxylan and cellulose
5.Order of occurrence
a.Arabinoxylan-50%
b.Cellulose- 25%
c.Beta glucan-5%

12. Use of Enzymes in mitigating ill
effects of NSPs & increasing
nutrient utilizationXylanase is the best enzyme – Cleaves Arabinoxylans
Glucanase – For glucans
Cellulase – for cellulose
Action-
1. Breaking down cell wall components – Releases encapsulated
nutrients
2. Reduce digesta viscosity increase passage rate
“Xylanase reduces duodenal (2.9/1.7) ileal(14/3.9)
jejunal(4.6/2.3) & AME(P<.01) of wheat
& starch digestion (P<.5) in jejunum and ileum”
(Choct M. Hougher,R.J. , Bed ford M.R. ,1999)

14. Xylamax
1. Endo 1,4 beta xylanase
2. Release 130 kcal from corn based diet and 150 kcal
from wheat based diet
3. Act as Prebiotic
4. FCR improves
5. Less pathogens
6. Less Neccrotic lesions
7. Improve Average finished weight and flock uniformity
8. Thermostable at pelleting -85⁰C

15. CONCLUSION
1.Knowledge of NSPs allow us to use Non
conventional feeds in efficiently increasing profit
2. Soluble NSPs are more detrimental as they reduce
passage rate hampering digestion
3.Use of enzyme like Xylanse glucanse etc.. in poultry
feed is of much importance in commercial poultry
rearing
