Kansas Agricultural Experiment Station Research Reports
Seventy-seven crossbred heifers (573 lb initial body weight) were developed in drylot and limit-fed a corn, sorghum silage diet predicted to produce gains of either 1 lb/day for the entire developmental period (EVENGAIN) or .25 lb/day for the first two-thirds of the period followed by 2 lb/day during the last third (LATEGAIN). Treatments began on November 15, 1993 and continued until April 25, 1994, the onset of the breeding season. Actual daily gains averaged 1.31 lb/day for EVENGAIN heifers, whereas LATEGAIN heifers averaged .55 lb/day for the first two-thirds of the feeding period and 2.5 lb daily for the last …
