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: 1.STRUKTUR RANTAINYA  ALIFATIS-AROMATIS-HETEROSIKLI 2.JML GGS NH2 DAN COOH  MONO….MONO… DST 3.REAKSI DLM LRT  ASAM, BASA, NETRAL 4.NUTRITIONAL  ESENSIAL-NON ESENSIAL 5.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: 1.SINTESA PROTOPLASMA DLM SEL 2.PERBAIKAN JARINGAN RUSAK 3.PENYIMPANAN PROTEIN 4.SINTESA ASAM EMPEDU 5.SINTESA HORMON 6.SINTESA ENSIM 7.SINTESA PROTEIN SUSU DAN ANTIBODI 8.SINTESA MELANIN 9.SINTESA RHODOPSIN 10.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 & Nonessential Amino Acids 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

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 highest90% Animal sources60-80% Plants40-60%

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
