Monozygous twin steers were used to investigate the beef production of Jersey cattle grazed under three different pastoral farming systems in New Zealand.

Marked differences in liveweight growth patterns were manifested in the three systems. Differences in liveweight and weight of carcass components early in the trial were later much reduced as a result of compensatory growth.

Subjective carcass grades reflected poor conformation and lack of fat cover with one carcass being downgraded for excessive yellow fat.

Differences in carcass weight accounted for most of the variation in carcass composition.

Subcutaneous fat colour varied considerably, with some evidence of genetic control.
