Selection and Dietary Quality of Beef Cattle Grazing Smooth Bromegrass, Switchgrass, and Big Bluestem
The ability of grazing animals to enhance quality of diet by selection is important in production. The study determined the effects of selection on dietary quality of cattle grazing monocultures of smooth bromegrass (Bromus inermis Leyss; SB), switchgrass (Panicum virgatum L.; SG), and big bluestem (Andropogon gerardii Vitman; BB) as influenced by plant maturity. Three ruminally-fistulated stee...
متن کاملDivergent Selection for In Vitro Dry Matter Digestibility in Switchgrass
The purposes of this study were to determine if phenotypic selection for in vitro dry matter digestibility (IVDMD) could be used to improve the IVDMD for switchgrass tPanicum virgatum L.) and to obtain heritability estimates of IVDMD in switchgrass. In 1973 a selection nursery of over 2,200 plants was established with transplanted seedlings of two similar Nebraska experimental strains. In 1974 ...
متن کاملRelation of Root and Shoot Morphology of Grass Seedlings
7-49 ABSTRACT Grass seedling establishment is dependent on adventitious root development. However, evaluating the establishment status of a seeding by excavating a population of seedlings and determining root morphology is difficult and generally will not be undertaken. Based on both field and greenhouse studies we have found that root and shoot morphological development is closely related with...
متن کاملSwitchgrass and Big Bluestem Hay, Biomass, and Seed Yield Response to Fire and Glyphosate Treatment
just below the soil surface, such as crown buds or rhizomes, aids plant tolerance to fire. Timing of spring fire and glyphosate [N-(phosphonomethyl)glyFire may not be an option for managing warm-season cine] treatments is critical to control weeds without compromising grasses in densely populated areas of the northeastern production of warm-season grasses. To determine the forage and seed USA w...
متن کاملShort-horned grasshopper subfamilies feed at different rateson big bluestem and switchgrass cultivars
Grasshopper species belonging to subfamilies Melanoplinae, Gomphocerinae and Oedipodinae were tested for their feeding rate on three types of grass. All grasshopper species were offered Shawnee and Kanlow cultivars of switchgrass, Panicum virgatum L. and big bluestem, Andropogon gerardii Vitman. The grasshoppers, Melanoplus femurrubrum and Melanoplus differentialis were also tested for their fe...
