Evaluation Of Supplemental Energy Source For Grazing Stocker Cattle, L. W. Lomas, J. K. Farney, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
A total of 216 steers grazing smooth bromegrass pastures were used to evaluate the effects of supplemental energy source on available forage, grazing gains, subsequent finishing gains, and carcass characteristics in 2014, 2015, 2016, 2017, 2018, and 2019. Supplementation treatments evaluated were: no supplement, a supplement with starch as the primary source of energy, and a supplement with fat as the primary energy source. Supplements were formulated to provide the same quantity of protein and energy per head, daily. Supplementation with the starch-based or fat-based supplement during the grazing phase resulted in higher (P<0.05) grazing gains than feeding no supplement during all six years. In 2014, 2016, 2017, 2018, and 2019, grazing gains of steers supplemented with the starch-based or fat-based supplement were similar (P>0.05). In 2015, steers …

A total of 180 steers grazing smooth bromegrass pastures were used to evaluate the effects of supplemental energy source on available forage, grazing gains, subsequent finishing gains, and carcass characteristics in 2014, 2015, 2016, 2017, and 2018. Supplementation treatments evaluated were: no supplement, a supplement with starch as the primary source of energy, and a supplement with fat as the primary source of energy. Supplements were formulated to provide the same quantity of protein and energy per head daily. Supplementation with the starch-based or fat-based supplement during the grazing phase resulted in higher (P<0.05) grazing gains than feeding no supplement during all five years. In 2014, 2016, 2017, and 2018, grazing gains of steers supplemented with the starch-based or fat-based supplement were similar (P>0.05). In 2015, steers supplemented with …

Supplementation of grazing cattle is most economically feasible when cattle prices are high relative to the price of grain. Energy supplementation of grazing ruminants may reduce forage intake and digestibility, but energy supplementation at low levels (less than 0.4% bodyweight) has been shown to have little effect on forage intake when crude protein was not limiting. Several studies have evaluated the effect of supplementation on stocker cattle gains and forage utilization during the grazing phase, but few have evaluated the effects of supplementation during the grazing phase on subsequent finishing performance and carcass traits. This research seeks to obtain a …
