2. PROBLEMS

3. Biotechnology in Animal Feed
Biotechnology is used to improve livestock feed by:
 Improving nutrient content
Improving the digestibility of low quality animal
feeds
Increasing production capability
Eliminating the deficiency of mineral ions or proteins

4. Main areas to focus upon
DEVELOPMENT OF GENETICALLY MODIFIED
FEED INGREDIENTS
In order to
nutritionally enhance
Improve production
capabilities
IMPROVE CERTAIN FEED INGREDIENTS
Which have;
Inheritably low nutritional
capabilities
Low protein content
Anti-nutritive factors
Deficiency of certain amino acids

5. Solution for Nutritional Improvement
Solution
Food
additives
Value added
feed stuff

6. Value added feed
NORMAL CORN
 Indigestible Phosphorous present in phytate
form.
Animals lack enzyme phytase to digest them
to get free phosphorous.
 Causes environmental pollution releasing
undigested Phosphorous into the
environment.
LOW PHYTATE CORN
Two to three times more highly digestible
inorganic phosphorus than normal corn .
More crude fat and protein present.
 Environment friendly.
 When broiler chicken was fed with this corn
they increased body weight, showed improved
feed conversion, increased linoleic acid in the
egg yolk.
High oil corn was also developed with more
fat and protein content.

7. Value added feed
 Low oligosaccharide soybean:
• Soybeans contain oligosaccharides that act as anti-nutritive factors .
• So less oligosaccharide content means increased amino acid and dry matter
digestibility.
 Soybeans with high Lysine:
• Lysine is essential for animal diet
•3 to 4.5% increase in lysine
•Reduces the supplementation addition of lysine

8. Value added feed
Genetically modified crops with
improved Amino acid profile:
 More amino acid content
 Less Nitrogen excretion in poultry

9. Value added feed
Golden rice:
 Reduced allergens in food
Improved nutritional
content
 More quantity
 Good quality
 Combats hunger and
malnutrition diseases.

10. Solution to the Problems: BIOTECHNOLOGY

11. Feed Additives
By
Ramsha Toor

12. What are Feed additives?
A feed additive is a food supplements for farm animals
that the animal cannot get enough from regular meals that
the farmers provide.
 these additives include vitamins, amino acids, fatty acids,
and minerals.
In some cases if an animal does not have some specific
nutrition in its diet it may not grow properly.
Adding these nutrients to the animal feed improves animal
digestion.

13. Commonly used Feed additives
A lot of feed additives are currently used and new concepts are
continuously developed
1.Enzymes
2.Pre-biotics
3.Pro-biotics
4.Dietary amino acids
5.Metabolic modifiers

14. Enzymes
Enzymes are the biological catalyst which when added to animal feed:
1.Improve the nutrient availability from feed stuffs
2.Lower feed costs
3.Reduce anti-nutritional effects from some feed ingredient
EXAMPLE:
Microbial phytase is an enzyme which breaks down the indigestible phytic acid
in cereals and oilseeds and release digestible phosphorus. This reduces the use
of expensive supplement inorganic phosphorus (dicalcium phosphate). Phyate
also releases other minerals like (Ca, Mg and Zn)

15. Probiotics
Probiotics is a term used to describe live
bacteria in animal feed.
Such beneficial, probiotic bacteria aid in
digestion and nutrient uptake of feed.
Probiotics also help to built beneficial bacteria
in intestine and exclude pathogenic bacteria
These probiotics release enzymes which helps
in the digestion of feed

16. Commonly used Probiotics
The most commonly used pro-biotic organisms are:
1.Aspergillus oryzae
2.Lactobacillus acidophilus
3.Streptococcus lactis
4.Saccharomyces cerevisiae
These can be administered through water or incorporated into the
feed.

17. Pre-biotics
Prebiotics are non-digestible food ingredients
that beneficially affect the host by selectively
stimulating the growth and activity of one or a
limited number of bacteria in the colon.
These are food for pro-biotics
1.Mannan oligosaccharide (MOS)
2.Mixed oligo dextrin
The advantage of re-biotics is that it can stand
high palletizing temperatures and help in long
shelf life of the feed

18. Minerals and Vitamins
The absorption and availability of inorganic trace minerals varies depending upon
1.the nature of the minerals (sulphate, oxide or carbonate)
2.their solubility
3.Trace minerals are now being attached to oligopeptides to make them more bioavailable.
In the case of vitamins due to varying availability and stability of vitamins in ingredients
supplemental vitamins are incorporated in diets.
These vitamins are much more stable than naturally occurring forms. Stability is achieved
through the application of advanced technologies which involve preparation of biologically
active derivatives, coating technologies, carriers and diluents.

19. Dietary Amino acids
Essential amino acids are added to the animal feed to get
balanced amino acid profile
The new trend is to formulate diets on digestible amino acids
so that protein requirement is reduced
Lysine is produced by microbial fermentation and added as a
supplement
Genetically modified microbes are being used to produce
threonine and tryptophan on commercial basis
Using these amino acids it is possible to lower dietary crude
protein level by 2-3% which is significant saving for the farmer

20. Metabolic modifiers
These molecules ae the group of compounds that modify animal metabolism in specific and
directed ways
1.Improving productive efficiency (milk yield per feed unit)
2.Improving carcass composition in growing animals
3.Increasing milk yield in lactating animals
Two classes of compounds are commonly used
1.Somatotropins
2.Adrenergic agonists

21. Metabolic modifiers
On commercial scale these compounds are produce by
using recombinant DNA technology to selectively produce
specific components for species
Bovine somatotropin is administrated in dairy cows
Administering of β androgenic agonist results in weight
gain and carcass leanness

22. Merits of using Biotechnology in animal
feeds
Increases the digestibility of low quality feeds through the addition
of supplements
Less phosphorus would be thrown in the litter and manure which
would lead to control of eutrophication and algal bloom
Reduces the use of expensive supplements (dicalcium phosphate)
Increase milk and meat yield
Decrease animal waste
Decrease the cost of animal feed
