Resum
Twenty Gascon young bulls that had been reared either in intensive conditions (INT) (n = 10) with early weaning at 3 to 4 months,
or in a traditional extensive (EXT) system (n = 10) with weaning at 7 months, were subjected to the same conditions during
the 145-day finishing period. Production system before the finishing period did not affect conformation, dressing percentage or
morphology of the carcass; nevertheless, tissue composition differed somewhat between the two groups. Display had a stronger
effect on meat colour than did production system. Percentage of myoglobin was highest in INT (P ⩽ 0.001), although meat texture
and sensory quality did not differ between rearing conditions. EXT animals had darker, more yellow fat, a higher percentage of
n-3 fatty acids (P ⩽ 0.001), a lower percentage of saturated fatty acids (P ⩽ 0.05) and a lower n-6/n-3 index (P ⩽ 0.001) than did
the INT-reared animals. Production system before the fattening period might modify some of the characteristics of commercial
beef, especially those associated with fat.
