“…Because of its heavy seed production, strong seedling vigor and low palatability to ruminants, it persists under moderate grazing (Mosjidis ) and can become invasive when not heavily grazed (Mantz et al . ; Coykendall and Houseman ). These traits have made SL a useful cultivated pasture forage in many parts of the world where it has proven to have adapted to a wide range of climates and soils and able to produce moderate crude protein (CP) (Mkhatshwa and Hoveland ; Mosjidis ; Pitman ).…”

Sericea lespedeza (Lespedeza cuneata [Dumont de Courset] G. Don.; SL) is a perennial, warm‐season legume containing condensed tannins (CT) that can play important roles in ruminant ecosystems. Our research objective was to determine season‐long average herbage CT fractions, crude protein (CP) and fiber concentrations under three harvest regimens for SL cv. AU Grazer at five locations within the southeastern USA during 2010. Harvest regimens were regrowth every 35 days (35‐day), previously uncut plots every 35 days (ACCUM), or regrowth when height reached 40 cm (40 cm). We found harvest regimen by location interactions (P ≤ 0.05) for all dependent variables. The ACCUM plants usually had greater (P ≤ 0.05) fiber concentrations where there were differences, except for the Louisiana location. The lowest (114 g kg−1; P ≤ 0.05) CP concentrations were measured in ACCUM plants at the driest location (Texas) while the highest (181 g kg−1 for North Carolina plants) came from the 35‐day regimen. Total CT (TCT) concentration varied (P ≤ 0.05) from a low of 61.1 g kg−1 for ACCUM plants in Louisiana to 100.7 g kg−1 for Texas plants harvested from 35‐day plots. In summary, harvest regimen influenced SL nutrient and CT concentrations. Fiber concentration was better correlated (−0.621 for acid detergent fiber; P ≤ 0.05) with TCT than CP (−0.014; P = 0.82). Sericea lespedeza regrowth harvested every 35 days had higher season‐long average TCT concentrations in two of five locations along with greater CP and less fiber concentrations in four of five locations compared to the ACCUM regimen.

“…S ericea lespedeza [ Lespedeza cuneata (Dumont de Courset) G. Don, SL] has many uses as an herbaceous perennial legume (Mosjidis, 1996, 2010; Muir et al, 2014). Its wide adaptation has resulted in naturalization throughout much of the southeastern United States of America (Hoveland et al, 1990; Diggs, Jr., et al, 1999), to the point that it outcompetes native species in some ecosystems (Mantz et al, 2013; Coykendall and Houseman, 2014). Traits such as adaptation to a wide range of climates and soils, ease of establishment, persistence under grazing [‘AU Grazer’ was released by Mosjidis (2001) as grazing tolerant], and high crude protein (CP) concentration have translated into a wide interest in using it as a pasture component throughout the world (Mkhatshwa and Hoveland, 1991; Mosjidis, 2001; Pitman, 2006).…”

Sericea lespedeza [Lespedeza cuneata (Dumont de Courset) G. Don., SL] is a perennial, warm‐season forage legume with wide adaptation, freeze tolerance, establishment ease, and persistence under grazing. It has high condensed tannin (CT) concentrations (g kg−1), which could be useful for methane mitigation and rumen bypass protein, as well as insect pest and gastro‐intestinal nematode suppression. However, CT concentration is variable. Our objective was to test CT, crude protein (CP), and fiber concentrations at five locations (Georgia, Alabama, North Carolina, Louisiana, and Texas) during a growing season. Established ‘AU Grazer’ SL regrowth and accumulated herbage in separate trials was sampled starting late April 2010 every 35 d for four dates. Regrowth CP concentration ranged (P ≤ 0.05) from 127 g kg−1 in North Carolina on date 3 up to 221 g kg−1 in Alabama on date 1. Sericea lespedeza regrowth in the warmest latitude (Louisiana) consistently contained among the greatest (P ≤ 0.05) acid detergent fiber. In regrowth herbage, we recorded a wide (P ≤ 0.05) total CT range, from 133.5 mg kg−1 in Texas on date 3 to 46.1 mg kg−1 in Louisiana on date 1, reflecting variability in fiber‐bound, protein‐bound, and especially extractible CT. Results from accumulated herbage reflected (P ≤ 0.05) herbage ontogenesis with less CP and greater fiber concentration with maturity but showed the same lack of CT concentration pattern as the regrowth herbage. These results indicate that SL herbage nutritive value and CT concentration is variable, so that any hay or pellets sold commercially for CT content should be assayed by environment and crop maturity.

“…In contrast with production-oriented grazing, stocking regimes for targeted grazing are chosen to encourage heavy defoliation of select, undesirable species at sensitive growth stages (Rinella and Bellows 2016). For example, targeted cattle grazing has typically been used to control introduced, invasive annual broadleaf weeds and grasses (Diamond et al 2012; James et al 2015), though it has also been used to reduce dominance of herbaceous perennials (Miller 1996; Launchbaugh and Walker 2006; Mantz et al 2013) and some woody species (Gutman et al 2000; Calleja et al 2019). Two previous studies that used targeted cattle grazing to suppress Texas wintergrass in mesquite/wintergrass-dominated grasslands reported mixed results.…”
