This agenda slide, titled "Capaian Pembelajaran" (Learning Outcomes), lists four key objectives on energy and protein in nutrition. They cover understanding concepts, explaining sources and systems, analyzing relationships and impacts, and applying to ruminants versus non-ruminants.

Capaian Pembelajaran

1. 1. Memahami konsep energi & protein
2. 2. Menjelaskan sumber & sistemnya
3. 3. Menganalisis hubungan & dampak
4. 4. Aplikasi pada ruminansia/non-ruminansia

Nutrition is essential for livestock growth, production, health, and metabolic energy. Proteins build tissues, enzymes, and hormones, while balanced nutrition boosts feed efficiency.

Peran Nutrisi

• Esensial untuk pertumbuhan, produksi, dan kesehatan ternak
• Sumber energi bagi aktivitas metabolisme
• Protein membangun jaringan, enzim, dan hormon
• Keseimbangan nutrisi tingkatkan efisiensi pakan

This slide is a section header for Section 04 titled "Konsep Energi" (Concept of Energy). The subtitle defines metabolic energy as calories absorbed and used by livestock for maintenance, growth, and lactation.

The slide "Sumber Energi" lists key energy sources: carbohydrates from starch and cellulose, and high-density energy from triglyceride fats. It also covers energy from protein via amino acid oxidation and from fiber through rumen fermentation producing volatile energy.

Sumber Energi

• Karbohidrat: pati dan selulosa sebagai sumber energi karbohidrat
• Lemak: trigliserida untuk energi tinggi densitas
• Protein: oksidasi asam amino menyediakan energi
• Serat: fermentasi rumen menghasilkan energi volatil

The "Sistem Energi" slide is a table listing three key energy systems with their descriptions. It defines DE as Digestible Energy, ME as Metabolizable Energy, and NE as Net Energy.

The slide "Sistem Energi pada Ternak" explains livestock feed energy systems. It defines GE as total feed energy, DE as GE minus fecal energy, ME as DE minus urine and gas energy, and NE as ME for maintenance and weight gain.

This slide serves as the section header for Section 08, titled "Konsep Protein" (Protein Concepts). The subtitle describes amino acid chains essential for synthesizing animal tissue and supporting livestock microbial populations.

Essential amino acids like lysine and methionine must be supplied through animal feed, while non-essential ones are synthesized by the livestock body. Protein quality is measured using PDCAAS (Protein Digestibility Corrected Amino Acid Score) or PDP.

Asam Amino

• Asam amino esensial: lisin, metionin, dll. (dari pakan)
• Asam amino non-esensial: disintesis oleh tubuh ternak
• Kualitas protein: diukur dengan PDCAAS/PDP
• PDCAAS = Protein Digestibility Corrected Amino Acid Score

Non-ruminants like pigs and chickens require high levels of essential amino acids (lysine, methionine, threonine) from high-quality feed proteins, as they cannot synthesize them. Ileal protein digestibility must exceed 80%, with efficient synthetic supplements like L-lysine HCl and DL-methionine reducing costs and boosting performance.

Protein pada Non-Ruminansia

Rumen microbes ferment carbohydrates and use ammonia from RDP/NPN to synthesize microbial protein, the primary nutrient source rich in essential amino acids absorbed in the omasum/abomasum. RDP degrades to ammonia for microbes in the rumen, UDP bypasses intact to the intestine, and NPN like urea hydrolyzes to ammonia for microbial protein synthesis.

The slide outlines the energy-protein relationship in a workflow table. High energy optimizes protein for tissue synthesis with minimal nitrogen waste, while low energy oxidizes protein for fuel (high urea waste), and E:P imbalance causes nitrogen or energy waste.

Deficiencies in energy/protein cause 20-30% stunting prevalence and 2-3x higher death risk due to low livestock immunity. Excesses lead to 15% nitrogen waste from surplus protein and 25% obesity risk from high-energy diets.

Dampak Kekurangan dan Kelebihan

• 20-30%: Prevalensi Stunting

This slide titled "Contoh Aplikasi" shows examples of livestock feed rations. It highlights dairy cow rations (60% carbohydrate energy, 16% protein), broiler starter phase (20% protein for early growth), and optimal MP/NE balance in formulations.
