  1. KUALITAS PROTEIN

  2. PENGUKURAN KUALITAS PROTEIN: NON RUMMINANSIA • MenggunakanNilaiBiologik • Metodekimiawi • Percobaanmakanan

  3. NilaiBiologik NB= N konsumsi-(N fese-N metabolik)-(N urin-Nendurin) x 100 N konsumsi – (N feses – N metabolik) N= nitrogen; N metabolik = nitrogen metabolikdalamfeses; N end urin = nitrogen endogen dalamurin. N metabolifeses (setiap g BK yang dikonsumsi: manusia = 0,1 g/hari; tikus = 0,1 g/hari; babi = 0,5 g/hari. N endogen urindihitungsbb: N (mg) = 1446 x w0,75

  4. PercobaanPakan Protein Efficiency rasio (PER) PER = pertambahanberatbadan/konsumsi protein Net Protein Retention (NPR) NPR = tambahanberat TPG – kehilanganberat NPG berat protein yang dikonsumsi TPG = kelompok yang diberimakan protein NPG = kelompok yang diberimakantanpaprotein yang sedangditeliti

  5. PercobaanPakan • Net protein utilization (NPU) NPU = N dlmtubuhkelompokuji – N dlmtubuhkelompoktanpa N Konsumsi N

  6. PENGUKURAN KUALITAS PROTEIN PADA RUMINANSIA • Protein tercerna (%) = PK (%) x 0,9115 – 3,67 PK = proteiinkasar
