Purdue ag economist Michael Langemeier discusses the key factors impacting feeding cost of gain in commercial feedlots. Though feeding cost of gain is influenced by many factors including type and quality of cattle fed, feeder weight, cattle performance, and feed prices; the vast majority of the variability in feeding cost of gain over time can be explained by feed conversion during the feeding period, and corn and alfalfa prices during the feeding period. The specific impact of each of these three factors is discussed in the video.
