  9. ZAT MAKANAN

  10. Zat Makanan Nutrients- any food product that functions in the support of life Six classes: • Water • Carbohydrates • Fats • Proteins • Minerals • Vitamins

  11. Water • Hydrogen + Oxygen • H2O – Water = Moisture ↓ ↓ Drink Water in feed Functions: • Metabolic reactions • Transporting nutrients and wastes • Maintains temperature • Major component of cell walls • Body made up of 60 – 70 %

  12. Carbohydrates • Carbon, hydrogen and oxygen • Primary function: • Source of energy • Located in plant and animal tissues • Simple carbohydrate- starches (grains) • Complex carbohydrate- cellulose (component of cell walls)

  13. Carbohydrates Simple carbohydrates • Monosaccharides • Glucose • Fructose • Galactose • Disaccharides • Sucrose (Glucose + fructose) • Maltose (Glucose + Glucose) • Lactose (Glucose + Galactose)

  14. Carbohydrates Complex carbohydrates • Cellulose • Ruminants require microbial fermentation to break down complex carbohydrates

  15. Fats • Also considered lipids • Carbon, hydrogen, oxygen • Functions: • Energy • 2.5 times more energy / unit

  16. Fats • Sources: • Fats- solid at room temperature • Oils- liquid at room temperature • Saturated fats • Unsaturated fats • Monounsaturated • Polyunsaturated

  17. Fats • Saturated fats C-C-C • Solid animal fats • Body can make • Unsaturated fats C=C=C • Monounsaturated C-C=C-C • One double bond • Polyunsaturated fats C=C=C • Two or more double bonds • Corn oil, Soybean oil

  18. Fats • Dietary essential fatty acids • Linoleic • Digestion of Fat Soluble vitamins ~ A,D,E,K • More of an issue in confinement fed animals • Added to the diet for • Reduce dust • Improve texture • Improve palatability

  19. Proteins • Contains hydrogen, carbon, oxygen, nitrogen • Chains of Amino Acids • Essential amino acids • Must be provide through the diet • Ruminants add in microbial growth • Non-essential amino acids • Required but the body can synthesize them

  20. Essential AA’s Histidine Arginine Lysine Isoleucine Methionine Leucine Threonine Valine Phenylalanine Tryptophan Nonessential AA’s Alanine Asparganine Aspertic acid Cysteine Cystine Glutamic acid Glutamine Glycine Hydroxyproline Proline Serine Tyrosine Essential & Nonessential Amino Acids

  21. Esensial Non Esensial Semi Esensial • H istidin • A rginin • L isin • L eusin • I soleusin • M etionin • V alin • P henilalanin • T riptoohan • A lanin • A sam Glutamat • A sam Aspartat • A sparagin • G lisin • G lutamin • S erin • P rolin • H idroksi Prolin • S istin • H idroksilisin • T irosin

  22. Protein • Functions: • Building blocks • Muscle, bone, connective tissue, milk production and cellular repair • Blood • Enzymes

  23. Minerals • Macro minerals • Required in large amounts • Micro minerals • Required in trace amounts • Trace minerals

  24. Macrominerals Calcium Chorine Magnesium Phosphorus Potassium Sodium Sulfur Microminerals Chromium Cobalt Copper Fluorine Iodine Iron Manganese Molybdenum Selenium Zinc Micro and Macro Minerals

  25. Vitamins • Organic (contain carbon) • Needed in small amounts • Functions: • 16 vitamins • Interact and need with minerals

  26. Vitamins • Sources • Fat soluble • Synthesized by ruminants • A, D, E, and K • Water soluble • Not synthesized by monogastrics, except horses, which takes place in cecum • B vitamins and C

  27. KLASIFIKASI PAKAN

  28. KLASIFIKASI BMT Didasarkan atas : 1. A S A L  Tanaman : - Hijauan segar - Hijauan kering - Hijauan awetan (silase, hay) - Jerami - Umbi-umbian - Butir-butiran/biji-bijian (padi, legum) - Kulit butir-butiran/biji-bijian - Limbah pertanian, industri minyak tanah dan industri lain  Hewan : - ikan - ternak / hewan lain  Makanan tambahan  Stimulator (growth + production)

  29. Classification of Feeds • Hijauan Kering dan Jerami • Hijauan Segar • Silase • Sumber Energy • Sumber Protein • Sumber Mineral • Sumber Vitamin • Non-nutritive additives

  30. Dry forages and roughages • 18% crude fiber, low TDN • High in cellulose, hemi-cellulose and lignin • Protein variable • Harvest date critical • Examples

  31. Dry forages and roughages • Examples: • Legumes • Alfalfa • 17% CP • Grass • Native grass • 12-13% CP • Other • Stalks • Corn cob husks • Soybean hulls 11% CP • Cottonseed hulls

  32. Pasture, range plants, and green forages • Types: • Native • 5,000 species • Cool / warm season • Cool – Brome • Warm – Native • Small grains • Wheat • Rye • Legumes • Alfalfa, Clovers • Problem due to Bloat

  33. Pasture, range plants, and green forages • Bloat: • Legumes cause excessive production of foams in the rumen • Foam inhibits the ability to eructate (Belch) • Gases form causing bloat • Animals cant breath • Anti-frothing agents • Bloat guard in blocks/mineral

  34. Silages • Variety of feed stuffs • Grasses • Legumes~ alfalfa, clovers • Grains~ corn, sorghum • Small Grains • ~ oats, rye

  35. Silages • Storage results in fermentation • Anaerobic bacteria • Bacteria produce lactic acid • Lowers pH to 4.0 or lower • High levels of heat 80-100oF • Optimum moisture content • 25-35% Dry Matter 75 – 65% Moisture • To dry will burn up

  36. Storage facilities • Bags, silos, bunkers

  37. Energy feeds • <18 crude fiber (or <35% cell wall) <20% CP • High in starch – grains • Examples: • Corn, 9%CP • Barley, high starch feed, <11% CP • Oats 12% • Wheat, 14% CP

  38. Energy feeds • Storage ~ very important • Future • Grains that are high in needed trait • High levels of Lysine • Low Levels of Phosphorus

  39. Protein supplements • Most critical, most expensive • Function: • Building blocks • Examples: • Animal • Plant

  40. Protein supplements Examples: • Animal origin: highest-readily available offer A.A. • Meat - • Blood - • Fish - • Feather - • Plant origin • Soybean meal- 44% • By-products • Distillers grain - 25 • Corn gluten - 25-30% • Soybean Hulls - • Non-protein nitrogen: not readily available a.a. • Urea 281% CP 80-90%

  41. Mineral supplement Concentrated or blended – carriers • Mixed with diet • Cost effective • Fed free choice • May over consume • Different vitamins and minerals in containers • Animals choose??? • Salt
