Climate variability and uncertainty associated with weather patterns can greatly impact feed security for cattle producers. Flooding, drought, and temperature extremes can reduce a farmer’s ability to produce a consistent crop, resulting in feed prices that can fluctuate greatly. Vertical farming systems that sprout cereal grains in a controlled environment, using precision irrigation, may alleviate the effects of external factors such as climate and resulting feed prices. The objective of this study was to determine if sprouted barley (SB) could be used as an effective alternative feed source for cow-calf pairs. Two diets were fed to 20 cow-calf pairs, a control diet consisting of 100% feeder-quality alfalfa hay, or an experimental diet comprised of feeder-quality alfalfa hay and a 12.6% dry matter inclusion of SB for 90 d. Body weight, feed intake, and feeding behavior were analyzed in the cows and calves. Ruminal health was also assessed in cows by analyzing the ruminal fluid for pH and volatile fatty acid composition. When health and performance metrics were analyzed, no differences were found between the two diets that were administered to the cattle
