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.
