Postweaning growth was not different for single and twin calves (P = .50); twin gain, relative to initial size, was higher.
Feedlot feed intake of twins was 85% of that for singletons (P = .20).
Twins were 90% of singleton live weight at slaughter and yielded 93% of singleton hot carcass weight (P = .12).
Twins were slightly older and significantly leaner at slaughter.
Returns less feed costs showed twin births to be associated with increased profit for cow-calf programs.
Returns less feed and overhead costs were higher for twin calves than for singles in the feedlot.
