This document classifies and describes various feedstuffs for livestock. It divides feedstuffs into three main categories: roughages, concentrates, and feed supplements/additives. Roughages include green and dry forages like grass, cultivated fodders, silage, and straw. They are bulky with low digestibility. Concentrates include energy-rich grains and protein-rich cakes/meals. Feed supplements provide vitamins, minerals, enzymes, and other additives. The document also describes various unconventional ingredients and how to classify feedstuffs for poultry based on their energy, protein, and filler content.

3. Roughages
 More than 18% CF and less than 60% TDN.
 More bulky
 Less digestible
 More lignin (Critical factor for digestibility).

4.  Maintenance type – 3 to 5% DCP - Green maize, Oat
 Non maintenance type – < 3% DCP - straw
 Production type - >5 DCP – Berseem and lucerne
Paddy straw
Lucerne
Green maize

5. 1) Green roughages
 60-90% moisture
 Grasses
 Cultivated fodders
 Pastures
 Root crops
 Silages
Grass

6. Pasture

7. Jowar fodder Maize fodder
Cultivated Fodders
Annuals

8. CO-4
Super Napier
Perennials

9. Green fodder - chopped
Silage

10. 2) Dry roughages
 10-15% moisture
 Straw
 Hay
 Stover
 Husk

11. Maize stover

13. Concentrates
 Less than 18% CF and more than 60% TDN.
 Less bulky
 More digestible
 Less lignin (Critical factor for digestibility).

14. 1) Energy rich
 Cereal grains, cereal mill byproducts, roots, and tubers.
Tubers Deoiled rice bran

15. 2) Protein rich
 Plant origin – Oil seed cakes, pulse chunnies, ddgs, oil meals, and
yeast.
 Animal origin – fish meal, meat meal, blood meal, dried skim milk.
DDGS CSC Blood meal

16. Feed supplements
 1) Vitamin supplements -
Rovimix, Vitablend.
 2) Mineral supplements –
Salt, limestone, dicalcium phosphate.
Dicalcium phosphate

17. Feed additives
 Antibiotics – Terramycin, Zinc bacitracin
 Enzymes – Amylase, lipase, protease
 Hormones – estrogen, progesterone
 Thyroprotein – iodinated casein
 Probiotics – yeast, microbes, lactobacillus
 Biostimulators – extracts of living organs
 Antioxidants – Vitamin E, BHT
 Mold inhibitors – Propionic acid, acetic acid
 Pellet binders – molasses, sodium bentonite
 Coccidiostats – amprolium, lasalocid

18. Unconventional feed additives
 Not used traditionally
Tamarind seed meal
Neem seed cake
Mahua seed cake

19. Classification of poultry feed stuffs
Energy –
 Maize, jowar, millets, barley, wheat, dorb, salseed meal, tapioca meal,
molasses, fats (Tallow – Beef fat; Lard – Pork fat), vegetable oils.
Protein –
 Vegetable - GNC, SBM, SFC, Sesame cake, CSC, Maize gluten meal,
Linseed cake.
 Animal – Fish meal, meat meal, blood meal, liver residue meal, silk
worm pupae meal, hatchery byproduct meal.

20.  SBM – Rich in lysine
 SFC – rich in arginine and methionine
 GNC – Rich in Arginine
 CSC – Gossypol toxin
 Maize gluten meal – Rich in Carotene and Xanthophyll
 Linseed Cake – Cyanogenic glycoside and Essential fatty acids.
 Fish meal – Can be fed up to 5%
 Meat meal – up to 5-10%
 Blood meal – up to 1.5-2.5%
Linseed cake

21. Filler –
 To provide dietary fiber/bulk.
 Eg: corncobs, feathers, cotton seed hulls, citrus pulp, straw, dorb,
wheat bran.
Corn cobs
Cotton seed hulls
Citrus pulp

22. Unconventional feed ingredients for poultry –
 Mango-seed kernel – 15-18% maize can be replaced.
 Berseem meal – 15% CP
 Alfalfa meal – 20% CP
Alfalfa meal
