Summary
Numerous studies have demonstrated the substantial economic benefit of using hormonal growth stimulants with feedlot heifers. The feed additive melengestrol acetate (MGA) and ear implants such as Synovex-H are commonly used for this purpose. Consistent improvements in both rate of gain and feed efficiency have been shown with these growth promotants. However, relatively few trials have directly compared MGA and Synovex-H under controlled conditions. Thus, the major objective of this study was to determine merit of these two growth stimulants.
In addition, this study presented an opportunity to compare the feedlot performance and carcass characteristics of two different groups of crossbred heifers.
