An overview of the pig production industry, its importance, and the roles and responsibilities of a pig production operator.
Introduction to Pig Production
Key concepts, stages, and best‑practice considerations for a successful swine enterprise.
| Advantage | Explanation |
|---|---|
| High Feed‑to‑Gain Efficiency | Pigs convert feed to body weight faster than many livestock species. |
| Short Production Cycle | From birth to market weight (≈ 100 kg) takes 5‑6 months. |
| Versatile Market | Whole carcass, pork cuts, specialty products (e.g., bacon, ham). |
| Adaptable to Various Systems | Small‑holder backyard units, medium‑scale farms, or intensive confinement operations. |
| Category | Common Breeds | Main Traits |
|---|---|---|
| Maternal (sow) lines | Large White, Landrace, Duroc (maternal) | Excellent mothering ability, large litters, good milk production. |
| Terminal (market) lines | Duroc, Pietrain, Hampshire | Rapid growth, high lean meat yield, good feed conversion. |
| Hybrid (cross‑bred) | Large White × Landrace, Duroc × Large White | Combine maternal and terminal strengths; most commercial herds use hybrids. |
Key physiological points
| Stage | Objective | Typical Management Actions |
|---|---|---|
| 1. Breeding & Gestation | Produce healthy, fertile sows and boars. | • Select breeding stock (genetics, health). • AI or natural service (AI preferred for genetics). • Provide gestation diet (≈ 2.5 % CP, 13 % ME). |
| 2. Farrowing | Safely deliver piglets and ensure early survival. | • Farrowing crates or pens (≈ 2 m² per sow). • Provide warm creep area (30 °C at birth, decreasing to 24 °C). • Monitor for dystocia, provide colostrum within 2 h. |
| 3. Nursery | Grow piglets to ~20 kg and prepare for weaning. | • Split‑lot by weight/age. • High‑protein starter diet (18‑20 % CP). • Maintain ambient 25‑28 °C, good ventilation. |
| 4. Grow‑out / Finishing | Achieve target market weight with optimal carcass quality. | • Phase‑feeding (grower, finisher). • Reduce CP to 16‑17 % CP, increase energy. • Space 0.7–0.9 m² per pig, provide ad lib water. |
| 5. Marketing / Slaughter | Deliver safe, high‑quality pork to processors. | • Record weight, health status. • Follow pre‑slaughter fasting (12 h) and handling guidelines. |
