Classification of feed stuff

1. CLASSIFICATION OF FEEDSTUFF Dr. P. Ravikanth Reddy MVSc , PhD Guest Faculty KBR College of Agriculture and Horticulture Acharya NG Ranga Agricultural University Dr. YSR Horticulture University

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

3. 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

4. 1) Green roughages 60-90% moisture Grasses Cultivated fodders Pastures Root crops Silages G rass

5. Pasture

6. Jowar fodder Maize fodder Cultivated Fodders Annuals

7. CO-4 Super Napier Perennials

8. Green fodder - chopped Silage

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

10. Maize stover Paddy straw vs. Hay Paddy straw

11. Hay Husk

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

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

14. 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

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

16. 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

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

18. 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.

19. 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

20. 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

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