An in vitro rumen batch culture study was completed to compare effects of common grasses, leguminous shrubs and non-leguminous shrubs used for livestock grazing in Australia and Ghana on CH4 production and fermentation characteristics. Grass species included Andropodon gayanus, Brachiaria ruziziensis and Pennisetum purpureum. Leguminous shrub species included Cajanus cajan, Cratylia argentea, G...

Legumes may also be used to extend the production season in the cooland warm-season grass pastures. Growing complementary plant species is an alternative approach Grazing systems using forage legumes increase animal to enhancing pasture production. Our objective was to estimate combining ability for native, warm-season grasses and legumes grown in production (Fribourg et al., 1979; Jung et al.,...

Microsatellites or simple sequence repeats (SSRs) are highly useful molecular markers for plant improvement. Expressed sequence tag (EST)-SSR markers have a higher rate of transferability across species than genomic SSR markers and are thus well suited for application in cross-species phylogenetic studies. Our objectives were to examine the amplification of tall fescue EST-SSR markers in 12 gra...

Silicon in forage reduces dry matter digestibility and may reduce grazing preference. Two studies were conducted with the following objectives: (1) to evaluate a method of determining grazing preference, and (2) to characterize the distribution and solubility of silicon in 31 accessions of C-3 grasses and relate these traits to grazing preference and estimated forage digestibility. Forage sampl...

the plant diversity of natural grassland communities, some producers in the Northeast often plant complex Some producers believe that planting pastures to several forage mixtures of grasses and legumes (Tracy and Sanderson, species benefits sustainability of grazing systems. We conducted a grazing study to determine if forage species diversity in pastures affects 2000; Sanderson et al., 2001) b...

for determination of grazing capacity, information of forage quality is essential which is influenced by various factors. the main objective of this research was investigation on effects of species, phenological stages, and life form on values of forage quality indices of six range species. species were two grasses (bromus tomentellus and dactylis glomerata), two forbs (ferula ovina and coronil...
