Management Shifting emphasis Banking on increased weaning weight to expand cow-calf revenue appears to have about run its course. “There’s quite a bit of evidence to suggest the trend for weaning weight is flat in commercial cow-calf operations in some parts of the country,” says Dave Lalman, Extension beef cattle specialist at Oklahoma State University (OSU). He’s referring to a recently published study he conducted with other researchers, indicating that weaning weights are no longer increasing in the northern half of the country and appear to be on their way to plateauing elsewhere. “Each operation needs to keep good records and use their own trend over time to make informed decisions about how best to improve ranch profitability” Lalman says. “Weight of calf weaned per cow exposed to breeding the previous year is probably the single most powerful metric to consider, because it combines growth and reproductive efficiency.” In the recent publication, researchers were only able to look at regional trends in calf weaning weight. However, other data (SPA, FINBIN, CHAPS, KFMA) suggest that weaning rate has been static in commercial herds for 25 years. “Therefore, it is unlikely that our industry has made recent progress in pounds weaned per cow exposed,” Lalman says. “If your operation is one that cannot document improvement over time in output [weaning weight and/or weight weaned per cow exposed] for the past 10 years, then your focus needs to shift more toward controlling cost of production and [/or] capturing postweaning value,” Lalman says. “This is particularly true if a ranch has aggressively selected herd sires and replacement heifers for weaning weight growth, with little or no evidence of progress over a period of five to 10 years.” Case in point: He explains Kansas Farm Management Association (KFMA) data indicate, depending on the year, that 60% to 66% of profitability improvement is due to lower cost of production. About 33% to 40% is the result of increased output. Kevin Herbel, KFMA executive director, and Dustin Pendell, an agricultural economist at Kansas Bill & Judy Daugherty 14210 Whites Mill Rd.
