Invited Review: Rise of craft breweries in the southeastern USA increases supplement availability for beef cattle

Abstract

Purpose: The purpose of this invited review was to discuss the current state of craft beer production and the generation, nutritional variability, and importance of wet brewers grains (WBG) as a livestock feed. This article also takes an in-depth look at logistical challenges of using WBG as a feed resource and how local communities are mitigating those challenges. Sources: Information provided came from the combination of published scientific resources and through experiences based on outreach services and real-world applications of using WBG as a byproduct feed for beef cattle. Synthesis: Wet brewers grains are often a cheap or no-cost feed for beef cattle producers located near craft breweries. The high concentrations of CP and digestible fiber make it a byproduct of interest for many beef cattle production systems. Moisture content is the greatest limitation, and additives for improved fermentation may be needed during storage of this high-moisture feed. Conclusions and Applications: The rise of craft breweries has increased the availability of WBG, which is an affordable feedstuff for beef cattle producers located near a brewery. Although there is variability in WBG between brews and craft breweries, successful incorporation of this byproduct into diets has occurred in all sectors of the beef industry. The on-farm handling and storage of WBG should be considered, and the addition of a feed additive may help to prevent spoilage and extend WBG shelf life. In local communities, logistical challenges may be somewhat averted when several smaller beef cattle producers work together on a WBG contract.
