limit feeding, growing program, metabolizable energy
One hundred twenty-eight Angus steer calves were utilized in a study to examine the effect of limit feeding on efficiency of metabolizable energy (ME) utilization during the grouping phase and subsequent performance during the finishing phase. Steers limit-fed a high concentrate diet exhibited more rapid d a i l y gains than steers full -fed the same amount of energy from a high roughage diet (2.15 vs 1.74 lb per head, respectively). Feed conversion was improved by limit feeding compared with full feeding (6.09 vs 10.19, respectively). The efficiency of ME utilization was also improved. Limit - fed steers gained .1242 l b per Mcal ME compared with .0956 lb per Mcal ME for the full - fed steers. Limit - fed cattle also required fewer days on feed (102 vs 117, respectively), gained weight more rapidly (3.43 vs 3.00 lb per head daily, respectively) and more efficiently (6.66 vs 7.53, respectively) than full-fed cattle during the finishing phase.
