  1. PROTEIN DARI BAHASA MESIR/YUNANI “PROTEUS” YANG UTAMA TERSUSUN DARI UNSUR C, H, O, N, S, P DENGAN KOMPOSISI SBB: CARBON 50% HIDROGEN 7% OKSIGEN 23% NITROGEN 16% 100/16=6,25N x 6,25= % PROTEIN SULPHUR 0-3% PHOSPOR 0-3%

  2. PROTEIN PROTEIN TERSUSUN DARI ASAM AMINO H R C COOH NH2

  3. Proteins • 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

  4. PROTEIN • KLASIFIKASI ASAM AMINO: • STRUKTUR RANTAINYA ALIFATIS-AROMATIS-HETEROSIKLI • JML GGS NH2 DAN COOHMONO….MONO… DST • REAKSI DLM LRT ASAM, BASA, NETRAL • NUTRITIONALESENSIAL-NON ESENSIAL • KATABOLISMEGLUKOGENIK-KETOGENIK-GLUKO/KETO CONTOH AA: GLISIN C2H5O2N ALANIN C3H7O2N PHENILALANIN C9H11O2N

  5. PROTEIN • SIFAT PROTEIN: • TGT JML DAN SSN AA YG MENYUSUN • BGMN POLIPEPTIDA TERIKAT SATU DG YG LAIN • KLASIFIKASI PROTEIN: • KOMPOSISI • SIMPLE PROTEIN • CONJUNGATED PROTEIN • CHROMO PROTEIN: HAEMOGLOBIN • GLYCOPROTEIN DAN MUCOPROTEIN: MUCIN • PHOSPOPROTEIN: CASEIN • LIPOPROTEIN: LIPOVITELIN • NUCLEOPROTEIN: NUKLEUS • BENTUK MOLEKUL • GLOBULAR • FIBROUS

  6. PROTEIN • KLASIFIKASI PROTEIN: • KELARUTAN • AIR • PELARUT ASAM • PELARUT BASA • ALKOHOL • FUNGSI • STRUKTURAL PROTEIN: KOLAGEN, KARTILAGO • KRONTRAKTIL PROTEIN: AKTIN DAN MIOSIN • ENSIM • HORMON • ANTIBODI • PROTEIN DARAH: ALBUMIN, FIBRINOGEN, Hb

  7. PROTEIN • FUNGSI ASAM AMINO: • SINTESA PROTOPLASMA DLM SEL • PERBAIKAN JARINGAN RUSAK • PENYIMPANAN PROTEIN • SINTESA ASAM EMPEDU • SINTESA HORMON • SINTESA ENSIM • SINTESA PROTEIN SUSU DAN ANTIBODI • SINTESA MELANIN • SINTESA RHODOPSIN • SUPPLY ENERGY

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

  9. PROTEIN • GEJALA DEFISIENSI PROTEIN: • UMUM: ODEMA • RANGKA: HAMBATAN PROLIFERASI DR SEL DLM AKTIFITAS OSTEOBLASTIK • JARINGAN PENGHUBUNG: KEGAGALAN PMBTK KOLAGEN • REPRODUKSI: ATROPI TESTES • OTOT: ATROPI OTOT CARDIALIS DAN OTOT RANGKA • SUMSUM TULANG: PENURUNAN PRODUKSI Hb

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

  11. Protein • Swine • Very important • Lysine a limiting amino acid in swine diets • Ruminants • Important, but….. Fermentation microbes can make them

  12. Protein • Sources • Vary in absorption rate • Egg proteins the highest 90% • Animal sources 60-80% • Plants 40-60%

  13. Protein • largest and most costly part of the ration • composed of amino acids

  14. Protein • enzymes are composed of protein • protein can be used to supply energy

  15. Protein • some animals need more protein than others • young animals • lactating (milk producing) animals

  16. Protein • twenty three types of amino acids • ten essential • thirteen nonessential

  17. Protein • crude protein content • total amount of protein in a feed • calculated by multiplying nitrogen content percentage times 6.25

  18. Protein • digestible protein • the protein in a feed that can be digested and used by the animal • usually about 50-80% of crude protein

  19. Protein • protein sources • animal • slaughterhouse by products • dried fish meal

  20. Protein • plant • superior to animal sources • cottonseed meal • soybean meal, linseed meal • peanut meal, corn meal

  21. Protein • balancing rations is based on the amino acid content
