Abstract

Studies of beef production systems often indicate profitability can be increased in calf growing and feeding programs if yearling cattle are grazed at least during part of the growing phase. If yearling cattle are grazed on summer range, it is important that the summer gain be as efficient and economical as possible. The use of implants and ionophores can improve gain in grazing cattle. A feed additive, bainbermycins (GainPro™), has been released for the purpose of improving weight gain in cattle, especially in those consuming high roughage diets. Data from practical grazing conditions are limited with bambermycins so the objective of this trial was to evaluate the effect of bambermycins, lasalocid (Bovatec®) and monensin (Rumensin®) on weight gain of yearling grazing steers when hand-fed daily on summer pasture.
