“…Annuals, such as sorghum × sudangrass (SXS), offer producers more flexibility and can produce forages with increased nutritive values compared with warm‐season perennials (Tracy et al., 2010). In the case of SXS, high forage yields, 7–10 Mg ha −1 , can be produced at a time of year when TF has become semi‐dormant and is not productive (Fontaneli, Sollenberger, & Staples, 2001; Machicek, Blaser, Darapuneni, & Rhoades, 2019). However, these summer annuals are less cost‐effective (Boyer et al., 2019; Keyser, Bates, Waller, Harper, & Holcomb, 2015; Tracy et al., 2010), may not be available in early summer (Tracy et al., 2010; Zechiel, 2017) and thus provide fewer grazing days (Zechiel, 2017) than perennials.…”
