The Suitability of Native Warm-Season Grasses for Equine
… gamagrass (Tripsacum dactyloides) (EG) yields, forage losses, changes in vegetative composition, and effects on equine bodyweight. Nine, 0.1-hectare plots were seeded with one of the three native grass treatments, and each plot was grazed by one Thoroughbred gelding in two grazing bouts, one in …

Computer aids for reclaiming eastern surface mines as rangelands
… was employed to determine the optimum forage species mixture to seed surface mined sites. With the optimum mixture determined, total costs for establishment, total monthly available dry matter, and percent crude protein content were calculated for each homogeneous range unit. These …

Evaluation of alternative forage species to reduce risk for cow-calf production systems in the Appalachian region
Optimizing forage productivity is essential to reduce pasture seasonality and ensure available forage to meet the nutritional needs of livestock. This study explores the risk-buffering ability of warm-season forages to fill the summer slump gap in production of cool-season grasses. Small plot …

Hair Sheep Production in Temperate, Deciduous Appalachian Silvopastures
… with different deciduous tree species are available. Forage and animal performance was compared from open systems (i.e., no trees) with that from silvopastures containing 13-yr-old honeylocust (Gleditsia triacanthos) or black walnut (Juglans nigra) trees. Cool-season grass-legume pastures …

Olfactory learning, its development and changing role in Honeybee (Apis Mellifera) behaviour
… linked to the field, where food sources are only available during certain periods of the day. A new technique was developed to investigate long term captivity and the effects this has on olfactory learning and homing abilities. In both these different, but crucial, learning criteria, captivity …

Intercropping for food, fiber, and fuel on pine plantations in Virginia and North Carolina
… Peanuts, Snap Beans, Tomatoes, Cucurbits, 3. Forage Crops: Grasses and Legumes, 4. Biomass Crops: sycamore, Sweet Gum, European Black Alder, Cottonwood. The ecological and management characteristics of these crops were examined to determine their compatibility with pine plantation management. …

Developing Breeding Objectives for Targhee Sheep
… could be used depending on whether winter forage was limited (L) or not (NL). The correlation between average indexes for these two scenarios was 0.78. Indexes were presented for combinations of feed cost and lamb value scenarios. Two indexes were suggested, representing the scenarios that …

Cover crops to regenerate soils and increase profitability in dryland crop production in the semi-arid central Great Plains
… a possible strategy to take advantage of plant available water (PAW) in wet years while saving PAW for primary crops in dry years. From 2015 to 2023, a series of small-plot and on-farm experiments were conducted to determine the best management strategies for CCs to replace fallow in NT dryland …

Effects of Fire on the Nutritional Ecology of Selected Ungulates in the Southern Black Hills, South Dakota
… and white-tailed deer, in summer. Based on forage removal and vegetation cover response, burning increased available forage for deer, elk, and cattle in the southern Black Hills. Within 3 years post fire, nutritional condition indices of mule deer were greater in burned than unburned …

Spatial Patterns and Population Performance of Mule Deer: Responses to Water Provisioning in Mojave National Preserve, California
… but those other 3 components are readily available, the provisioning of water is expected to benefit populations of wildlife. Development of water sources in arid regions of the western United States has been a common practice used by wildlife and range managers in both state and federal …
