Description
An experiment was designed to compare beef production by three successions of light weight steers continuous grazing two kinds of irrigated pastures. Two growth promotant ear implants were superimposed treatments in 1982. Successions of light weight steers were used in an effort to obtain maximum animal gain per ha, comparing rates of gain and gains per ha by trimesters. Average steer gains per ha from orchardgrass (Dactylis glomerata) and from perennial ryegrass (Lolium perenne) over a 4-year period were nearly the same. Average daily gains by steers that grazed perennial ryegrass were greater than by steers that grazed orchardgrass but the latter supported more steers per ha. Steers implanted with Compudose® gained faster than steers implanted with Synovex:-S®. This research has led to the increased use of light (275 kg) steers for succession grazing on single species (perennial ryegrass or orchardgrass) pastures rather than multi-forage species mixtures. Steers grazing irrigated pastures in a wide area are now ear-implanted with one of these growth promotants.
