Cost of Production
Feed represents 75% of that cost
How do we brake down these costs
Weaning =>30/40kg
Maximise growth,Maximise output
30/40kg =>Slaughter

Conclusion
Compensatory growth in pigs is expensive
Early performance advantages increase in
valueover the lifetime of the pig
Ensure feeding regime is weight targeted
Maximise net gain,not minimise
input cost
