Effect of growth rate on pork eating quality-
Research partners: AHDB Pork Pork Chain Unit (University of Bristol) and AHDB Pork Pig Development Centre (University of Leeds)
Industrial partners: Tulip supply group
Project duration: 2006 – 2008
Aims and objectives
To investigate both objectively as well as subjectively whether pig growth rate has an impact on pork quality.
- Fast growing pigs produced more tender and juicy pork than slow growing pigs
- At 110kg the growth rate effect on tenderness was significantly greater than at 90kg
- Overall liking score at 110kg was significantly higher in fast than in slow growing pigs
- There is no evidence that slow or interrupted growth increases boar taint prevalence
- Levels of boar taint compounds were higher in fast growing males, but sensory analysis did not reflect a detrimental effect on flavour.
