A new study led by the Virginia Tech's College of Agriculture and Life Sciences reveals that market-ready steers can maintain meat quality and yield even when fed lower-cost, low-input maintenance diets for longer periods than previously understood.
The finding is especially useful to cattle producers and feedlot operators during times of market unpredictability and processing slowdowns such as those experienced during the COVID-19 pandemic.
During the early stages of the pandemic, social distancing measures and lockdowns led many meat processors to shut down or scale back operations. As a result, many beef producers and feedlots had to retain cattle for long periods of time under uncertain market conditions and risk financial loss.
The study, led by Virginia Tech's School of Animal Sciences in collaboration with colleagues at the University of São Paulo in Brazil, sought to determine whether finished steers could retain their ability to produce high-quality beef when transitioned and held on less-expensive maintenance diets while markets improved.
The research focused on 16 finished commercial Angus-crossbred steers, each weighing approximately 590 kilograms, or about 1,300 pounds. Once market ready, these steers were placed on one of two maintenance rations consisting of predominately forage or grain diets for 60 days. At the end of this holding period, cattle were harvested and the quality of the beef was assessed using American Meat Science Association standards for color, weight, yield, maturity, and marbling.
