N2  - Four groups of male lambs were fed on liquid diets to give them four different calcium intakes (50, 250, 450, and 650 mg calcium/kg liveweight/day) from 5 to 70 days of age. Dry matter intake, liveweight gain, and serum calcium levels (but not food conversion efficiency) were reduced in those animals consuming 50 mg calcium/kg/day, but there were no significant differences between the lambs receiving 250, 450, or 650 mg/kg/day. Femur development in the lambs consuming 50 mg/kg/day was inadequate: the bone was brittle and tended to fracture. Although femurs taken from the animals receiving 250mg/kg/day were not fully developed, they appeared to be structurally sound. It is concluded that a calcium intake of 250 mg/kg/day is likely to be adequate for young lambs slaughtered for meat production at an early age.
