Extract

Growth rate is an important performance indicator in pig production and therefore influences profitability. There is also evidence that faster growing pigs have superior tenderness (MLC, 1989), possibly linked to faster muscle protein deposition through the activity and expression of proteolytic enzymes. Slow growth could also result in higher boar taint levels in entire male pigs because they will be older and sexually more mature at slaughter (MLC, 1989). The current project was therefore undertaken to investigate the effect of variations in growth rate on tenderness and boar taint.
