Abstra.ct.-Eight hardwood species were planted at five spacings in a minor stream bottom in southeast Arkansas. Hecause of inherent differences in nutrient requirements and tree development, only four oak species are covered in this paper. Spacing gp.nerally did not affect nutrient concentrations , but differences did exist among species. Leaves constituted only 10-15 percent of aboveground bio...
ufactured feeds that complement specific forages. For example, when alfalfa hay is used, the amounts of protein and calcium included in the concentrate can be significantly reduced. However, horse owners often have difficulty distinguishing among forages, making the successful application of this approach difficult. The approach with the most potential to reduce nutrient excretion by horses wou...
During the twentieth century, agricultural production strived to achieve increased food production in order to satisfy both local and export demands. In many cases, this led to increased farm sizes and an operational separation of crop and livestock production. Society fears that the trend of increasing centralization and industrialization of agriculture, specifically animal agriculture, has re...
Designing a sound cow-calf nutritional program requires knowledge of nutrient requirements, diet quality, and intake. Effectively using the NRC (1996) beef cattle requirements model (1996NRC) also requires knowledge of dietary degradable intake protein (DIP) and microbial efficiency. Objectives of this paper are to 1) describe a framework in which 1996NRC-applicable data can be generated, 2) de...
pretation of sugarand calorierelated nutrient-content claims through transparent food marketing are needed steps to empower parents to make informed choices. If the FDA revised the current labeling requirements for foods and beverages bearing sugarand calorie-related nutrient-content claims in this way, the replacement of added sugars with other sweet ingredients would be clearly highlighted. A...
