Study Notes
Overview of Pig Production
- Pigs are originally native to Europe and Asia but have been domesticated and introduced globally, including North and South America and Australia.
- Modern pigs are larger and more muscular but retain many wild behaviors, allowing them to adapt and expand populations if released.
- As an invasive species, pigs lack natural predators, allowing rapid breeding rates that overwhelm potential predation.
Reproduction and Litter Size
- Pigs can have two litters each year, with each litter averaging about 15 piglets.
- The variability of pig production worldwide, reflects different farming systems and practices.
Types of Pig Production Systems
-
Scavenging Pigs:
- Based on traditional free-range systems where pigs roam household areas.
- Omnivorous diet but face challenges such as poor feed quality and zoonotic disease transmission.
-
Small-Scale Confined Production:
- Pigs are entirely dependent on their keepers for feed, allowing for controlled diets.
- Local markets benefit from this production as it marks the transition to business-oriented pig farming.
- Hog prices are cyclical, with variations approximately every four years, referred to as the Hog Cycle.
-
Integrated Production Systems:
- Involves raising pigs alongside other agricultural activities, fostering nutrient cycling (e.g., using pig manure for crops).
- Risks include potential disease transmission between species.
-
Large-Scale Confined Production:
- Reflected by larger farm sizes and specialized farming activities.
- May involve multiple sites for different stages of production (farrowing, nursing, finishing).
- Consolidation occurs through joint ownership for feed milling and pork processing.
Production Practices and Benefits
-
All-in-all-out System:
- Grouping animals by age and weight, allowing for complete emptying of facilities to improve sanitation and control diseases.
- Benefits include reduced disease transmission, better environmental control, and enhanced record-keeping.
-
Breeding Techniques:
- Focus on creating hybrids from purebreds for specific traits, improving meat quality and fertility.
- Hybrid pigs are typically not bred back to purebreds to avoid genetic complications.
-
Large Scale Outdoor Production:
- Provides better animal welfare but involves higher production costs and reduced herd sizes.
- Premium pricing can be charged due to the welfare benefits.
Additional Components of Pig Production
- Key roles include service providers such as veterinarians who oversee disease prevention and manage drug withdrawal times before slaughter.
- Collaborations exist among production groups to ensure meat safety and quality.
- International trade dynamics reveal that specific cuts of pork are distributed based on market demands, such as North America exporting ham to the UK and importing ribs.
