Pelleted Feeds With And Without Antibiotics For Fattening Lambs, L. F. Bush, R. M. Jordan

Research Bulletins of the South Dakota Agricultural Experiment Station (1887-2011)

Two lamb feeding trials were conducted to determine if it paid to pellet rations and to study the value of antibiotics in fattening rations.
Lambs fed pelleted rations gained slightly faster and more efficiently than those not fed pellets. However, grinding, mixing, and pelleting costs more than offset this advantage.
Carcass yields were slightly higher for lambs fed pelleted rations (average of both trials). The carcass grade was about one-third of a standard grade lower.
Results from adding 10 milligrams of aureomycin per pound of feed were not consistent for both trials. Aureomycin stimulated growth and increased feed efficiency in …
