“…Catalano et al. (2019) reported a change in WC to grass ratio from 5.1:1 in the seeding year to 0.8:1 in the first production year, and Schils et al. (1999) reported that the grazing activity of the dairy cows reduced clover content by 12% compared to the cutting control.…”

“…If a horse consumed 2.0% of their bodyweight (BW) on a dry matter (DM) basis each day, the reported equine DE values for all grasses would meet or exceed the horse's needs. Equine DE is not commonly reported for perennial CSG; however, it has been discussed for annual CSG (Grev, Sheaffer, DeBoer, Catalano, & Martinson, 2017), annual warm season grasses (DeBoer et al., 2017), and legumes under horse grazing (Catalano et al., 2019). In other forage species, equine DE ranged from 2.0 to 2.77 Mcal kg −1 (DeBoer et al., 2017; Grev et al., 2017; Catalano et al., 2019).…”

Yield, persistence, forage nutritive value, and preference of perennial ryegrass under grazing

Perennial ryegrass (PR) is a quality and high yielding forage that tends to lack winter hardiness to persist in the upper Midwest. The objective was to evaluate yield, stand persistence, forage nutritive value, and preference of experimental populations of winter hardy PR grown in monoculture and in mixture with white clover under livestock grazing. Research was conducted in St. Paul and Grand Rapids, MN. Meadow fescue (MF), tall fescue (TF), orchardgrass (OG), a reference PR, and two experimental populations of PR were grazed every 32 days by either horses (St. Paul) or cow-calf pairs (Grand Rapids). Prior to grazing, forage yield and quality samples were collected, and post-grazing, fields were visually assessed for the percentage of forage removal to determine preference. Yields of all PR (6.9 to 7.6 Mg ha −1) were similar, but lower compared to other coolseason grasses (CSG). Persistence was similar among all CSG in St. Paul; however, it was lower for all PR in Grand Rapids compared to other CSG. All PR were highly preferred by both horses (≥74% removal) and cattle (≥70% removal) and were consistently among the highest for crude protein (CP; 200 g kg −1), equine digestible energy (DE; 2.35 Mcal kg −1) and bovine metabolizable energy (ME; 2.6 Mcal kg −1), moderate for nonstructural carbohydrates (NSC; 136 g kg −1), and among the lowest for neutral detergent fiber (NDF; 518 g kg −1). Experimental populations of PR produced forage of high nutritive value, but yield and stand persistence may be less compared to other CSG at some locations. 1 INTRODUCTION Cool-season perennial grasses (CSG) are the foundation of productive pastures in the upper Midwest (Allen, Sheaf

“…As a result, there were nine different treatments, including Kentucky bluegrass, Kentucky bluegrass–alfalfa mixture, Kentucky bluegrass–white clover mixture, meadow fescue, meadow fescue–alfalfa mixture, meadow fescue–white clover mixture, orchardgrass, orchardgrass–alfalfa mixture, and orchardgrass–white clover mixture. Plots measured 22 by 12 ft, and seeding rates were 25, 15, 6, 10, and 3 lb per acre, respectively, for meadow fescue, orchardgrass, Kentucky bluegrass, alfalfa, and white clover (Allen et al., 2013; Catalano, Sheaffer, Grev, DeBoer, & Martinson, 2019). Soil pH, potassium (K), and phosphorous (P) were adequate for grass–legume pasture production according to Minnesota fertility guidelines (6.6 pH, 85 ppm K, 18 ppm P) (Kaiser, Lamb, & Eliason, 2011).…”

“…When horses grazed perennial cool‐season grasses in monoculture, Kentucky bluegrass and meadow fescue were among the most preferred grasses (>60% removal), whereas orchardgrass was among the least preferred (47% removal) (Allen et al., 2013). Additionally, in research evaluating legumes under horse grazing, horses preferred white and red clover ( Trifolium pratense L.) compared with alfalfa (Catalano et al., 2019). Although research comparing horse preferences of legume–grass mixtures is largely unavailable, legumes resulted in improved palatability among grazing ruminants (Rutter, 2006).…”

Cool-season perennial grasses are the foundation of productive horse pastures in the north-central United States. The addition of legumes in pastures can increase forage mass and digestible energy content, yet little research has investigated grass-legume pastures under horse grazing. The objectives of this research were to evaluate herbage mass, botanical composition, forage nutritive value, and preference of grass-legume pastures under horse grazing. Plots consisting of orchardgrass (Dactylis glomerata L.), Kentucky bluegrass (Poa pratensis L.), and meadow fescue (Festuca pratensis Huds.) were planted in monoculture and in binary mixtures with alfalfa (Medicago sativa L.) or white clover (Trifolium repens L.) and grazed by horses in Minnesota during the 2013, 2014, and 2015 grazing seasons. Herbage mass, weed mass, and forage nutritive values were determined prior to grazing, and horse preference was evaluated following grazing. When evaluating herbage mass, the inclusion of alfalfa resulted in a consistently higher mass than grass monoculture. Kentucky bluegrass mixtures resulted in a decreased mass of non-sown (weed) species and an increase in horse preference. Improved forage nutritive values were also observed with the inclusion of legumes regardless of grass species, including higher crude protein and neutral detergent fiber digestibility at 48 h and lower neutral detergent fiber. As a result, using grass-legume mixtures in pastures can provide benefits for grazing horses and pasture productivity. 1 THE IMPORTANCE OF PASTURE TO THE HORSE Forages are an important component of the equine (Equus Caballus L.) diet, and previous surveys have reported >80% Abbreviations: BCS, body condition score; BW, bodyweight; CP, crude protein; NDF, neutral detergent fiber; NDFD48, neutral detergent fiber digestibility at 48 h.
