Lignification and Tannin Localization During the Development of Birdsfoot Trefoil Stems

Abstract: Stem dry matter accumulation is correlated with a decline in digestibility in both birdsfoot trefoil (Lotus corniculatus L. [BFT]) and alfalfa (Medicago sativa L.), and the shear force required to harvest mature BFT stems can inhibit BFT grazing by ruminants. Decline in digestibility and increase in shear force are both correlated with increase in stem lignin content. Alfalfa stem development has been well documented, and our objective was to analyze stem development, lignification and tannin in BFT stems usin… Show more

“…Hays fed were: birdsfoot trefoil (BFT; Lotus corniculatus L., variety Langille), sainfoin (SAN; Onobrychis viciifolia Scop., variety Shoshone), small burnet (SML; Sanguisorba minor Scop., variety Delar), alfalfa (ALF; Medicago sativa L., variety DKA43-22RR), cicer milkvetch (CMV; Astragalus cicer L., variety Monarch), and meadow bromegrass (MB; Bromis riparius Rehmann, variety Cache; Jensen et al, 2004). Birdsfoot trefoil and SAN are tannincontaining legumes (Hunt et al, 2014;Wang et al, 2015), SML is a tannin-containing forb (Barry and McNabb, 1999), ALF and CMV are non-tannincontaining legumes (Broderick and Albrecht, 1997), and MB is a grass. All hays were cut in June of 2016 and at that time the legumes and SML were in the early flowering stage of development while MB was in the heading stage.…”

“…Differences in lignin composition and structure between alfalfa hay and birdsfoot trefoil hay can also influence the digestibility of NDF in the rumen; despite birdsfoot trefoil hay having 15% increased lignin concentration, in vitro NDF digestibility of birdsfoot trefoil hay was numerically greater than alfalfa hay (35.8 vs. 31.2%; Table 1). Recently, Hunt et al (2014) reported that lignification of stems and leaves of birdsfoot trefoil as plants matured and elongated was different from that of alfalfa, thereby causing potential cell wall differences that could affect digestion rates of NDF in the 2 legume forages. In addition to cell wall chemical differences, MacAdam and Griggs (2013) reported greater NFC concentration in birdsfoot trefoil hay than alfalfa hay when both species were harvested at 6-wk intervals.…”

“…While ALF and CMV had similar whole‐plant ADL concentrations, ALF has more rigid, erect stems whereas CMV has less rigid, vine‐like stems. These differences in stem structure could result from differences in the amount, type, or localization of lignin in stem‐fiber cell walls 44 and result in greater isolated NDF DDM of CMV compared with ALF. The grass had the least ADL, which was positively correlated with undigested NDF OM and negatively correlated with isolated NDF asymptotic gas volume.…”
