Abstract
The extensive swath grazing systems of barley (Hordeum vulgare) and an annual polycrop mixture were evaluated for forage yield, forage quality, cattle grazing capacity, and cost of production in 2017 and 2018. A 13.2 ha site located at Livestock and Forage Centre of Excellence Termuende Research Ranch was seeded in June and grazing commenced in November of each year. The annual polycrop mixture was Union Forage Ultimate Annual Blend with the addition of 40-10 forage peas (Pisum sativa). The Ultimate Annual Blend included the following species: hairy vetch (Vicia villosa), crimson clover (Trifolium incarnatum), Italian ryegrass (Lolium multiflorum), sorghum (Sorghum bicolor), Winfred forage brassica (Brassica napus ssp. biennis), Hunter Brassica (Brassica rapa syn.B campestris), and Graza Forage Brassica forage brassica (Raphanus sativa ssp. maritimus). The barley cultivar was CDC Maverick barley.
