Animal and forage responses on Maximus, a tetraploid cultivar vs Marshall, a diploid cultivar of annual ryegrass

“…The linear decrease in ADG with increasing SR observed in this study is a common response that has been reported in numerous other studies (e.g., Derner, Hart, Smith, & Waggoner, ; Gunter, Beck, Hutchison, & Phillips, ; Inyang et al., ; Morgan et al., ; Phillips, Hart, Glimp, & Vontungeln, ; Sharrow et al., ; Stewart et al., ). Daily gains observed in this study were similar to those reported for annual ryegrass of 1.0 to 1.2 kg/d (Islam et al., ; Zaragoza‐Ramírez, Bransby, & Duffy, ). Sollenberger and Vanzant () reported that across a wide range of HM or forage allowance, a high proportion (60% to 90%) of variation in ADG is attributed to quantity.…”

A Novel Approach to Grass–Legume Management

“…Based on the SR eff ect, it appears that low herbage mass availability on annual ryegrass pastures, which leads to reduced forage allowance, may have limited animal performance at high SR in our study. Zaragoza-Ramírez et al (2008) reported ADG ranging from 1.0 to 1.2 kg for stocking rates ranging from 8 to 2 steers ha −1 grazing annual ryegrass, respectively.…”

Oat, rye, and ryegrass response to nitrogen fertilizer

“…This difference can be attributed to lower N content and less aboveground biomass measured for ryegrass compared with other species. However, ryegrass is known to produce a dense, shallow root system (Curran et al, 2018) and has performed well in stocker cattle grazing situations in Alabama (Siri‐Prieto et al, 2007; Zaragoza‐Ramirez et al, 2008).…”
