Yield, Quality, and Botanical Composition of Autumn-Accumulated Grass-Legume Mixtures and Digestibility of Ensiled Autumn-Accumulated Orchardgrass and Alfalfa
… on September 3 were ensiled alone. Chemical composition of silages was determined after 90 d of fermentation. Silages averaged 16.0% CP and 44.7% NDF. Digestibility of the ensiled stockpiled forages was estimated using acid insoluble ash as a marker with 18 wether lambs. No differences were …

Assessing the reliability of plant-wax markers to delineate diet choice and feed efficiency in beef heifers
… reliability of plant-wax markers for estimating botanical composition of test diets, and diet choices in beef cattle, and provided opportunities to evaluate efficiency in growing heifers. To test estimation of botanical composition, samples of red clover and fescue hay were mixed to form test …

Estimating forage yields with simple methods
… pasture yield and one method of estimating botanical composition were investigated. The four methods for estimating yields: Visual, Comparative, Yield Index, and Disc, and the Visual estimate of botanical composition, were performed by several estimators on a series of experiments before and …

Management and nutritional quality of tall fescue and alfalfa grown in combination, compared to tall fescue fertilized with nitrogen
… September stockpiling of fescue-alfalfa improved botanical composition, yield, and forage quality, compared to August stockpiling. September stockpiling of N-fertilized fescue improved quality but lowered yield, compared to August stockpiling. Fescue-alfalfa had higher (P<0.05) yield and improved …

Comparison of techniques for estimating pasture herbage mass and productive ground cover for Lakota prairie grass, Kentucky 31 endophyte free tall fescue, Kentucky 31 endophyte infected tall fescue and Quantum 542 tall fescue grazed by stocker steers
… conducted in 2003 through 2005 to investigate botanical composition and yield of "Lakota" prairie grass (Bromus catharticus Vahl.), "Kentucky 31" endophyte-infected (KY31 E+), endophyte-free (KY31 E-), and "Quantum" tall fescue (non toxic endophyte infected) under grazing by stocker steers. …

Effects of three clipping managements on growth and production of a Kentucky bluegrass-clover sward
… University Livestock Farm. Herbage accumulation, botanical composition, leaf extension rate (LER), leaf appearance rate (LAR), and tiller density were observed. The sward was clipped to three heights, 2.5, 5.1, and 7.6 cm, from a recovery growth of 13 to 15 cm. Nitrogen was applied in split …

From forest to pasture without weeds: A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science with Honours at Lincoln University
Dry matter production, botanical composition and seedling size of a ryegrass/ subterranean clover pasture sown on 1 April out of Pinus radiata were measured over three harvest dates (28 July, 17 August, 7 September) in Darfield (43° B'S, 172° 8'E). Pasture was grown at 4 lime rates (0, 2.5, 5, 10 T …

Poultry Litter as a Nutrient Source for Low Input Forage Systems
… fertilizers on soil fertility, aboveground botanical composition and soil seed bank composition of established mixed naturalized pastures. Two sites each had the following treatments applied for two consecutive years: 1) split application of litter: 3.36 Mg ha-1 in spring and 3.36 Mg ha-1 in …

Grazing management strategies of diverse pastures on irrigated dairy farm systems : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… in spring and autumn on herbage DM production, botanical composition, herbage quality, and milk production of lactating dairy cows grazing diverse pastures. Four field experiments were conducted in Canterbury, New Zealand on irrigated diverse pastures grazed by dairy cows. Data were used in the …

Community Decision Making Aids for Improved Pasture Resources in the Madiama Commune of Mali
… tethered at two different residual heights on botanical composition, forage biomass and animal performance. Young sheep weighing approximately 18-24 kg were tethered for a certain period of time depending on residual canopy height. Two treatments 3 or 6 cm residual height were each replicated 4 …

Assessing the potential of mixed grazing goats with beef cattle to improve animal performance and increase the utilization of marginal pasturelands in the Appalachian coal region
… grazing goats with cattle on forage biomass, botanical composition, relative plant abundance, and animal performance. The three treatments included an ungrazed control, cattle grazing alone, and mixed grazing goats with cattle. Experimental design was a randomized complete block design with …

Impact of shade on cool-season forage mixtures for the Mid-Atlantic region
… shade and mixture complexity on sward yield, botanical composition, nutritive characteristics and ergot alkaloid concentrations. Slatted shade structures created 30, 50, and 70% shade compared to full sun. Three forage mixtures were evaluated (SIMPLE = tall fescue and white clover; …

Management and Livestock Performance of Alfalfa-Tall Fescue Mixed Stands
… and month and were evaluated using detailed botanical composition and persistence measurements. Defoliation height, rest period, and month all affected alfalfa-tall fescue competition. Alfalfa was generally more competitive with longer rest periods and shorter heights, although results were …

Estimation of the proportions of grass and legume in extrusa of esophageallly-fistulated animals
… grab samples were extrapolated from slopes. The botanical composition of grab samples differed (P<.001) from that of extrusas for both components and for both animals. Extrapolation from NDF values tended to overestimate the proportion of grass in extrusa samples and underestimate it in grab …
