Nigeria is one of the most malnourished and hunger ridden in the league of developing countries; according to reports of Food and Agricultural Organization (FAO) of United Nations estimated daily animal protein intake for developing countries averaged at 4.5 g/head/day at the beginning of this century which has hardly risen to 10 g/head/day into the second decade of the century in Nigeria. This...
In Wisconsin, the prevalence of dairy and livestock farming has led to questions about how animal agriculture affects the environment. As of 2003, managed grazing was practiced on 23 percent of Wisconsin dairy farms (Taylor and Foltz 2006). Many farmers who practice managed grazing (graziers) have observed environmental benefits resulting from this management system. What have scientific studie...

Facial eczema, a disease of sheep and, to a lesser extent, of cattle, has long been known in the North Island, New Zealand. The disease is contracted by grazing in pastures infected with the fungus Pithomyces chartarum (Commonwealth Mycological Institute Herbarium no. 74473). Synge & White (1959) isolated from cultures of this fungus a metabolic product which they named sporidesmin. Crystalline...
The ultimate goal of monetary policy is to achieve price stability and high output. In this regard, central banks usually change the interest rate, liquidity, and money base in order to apply monetary policies. The John B. Taylor rule is one of the rules known in the transmission of monetary policy.[1] Based on this rule and given the output gap and inflation gap, the central bank increases or ...
Using in situ mesocosm experiments, we compared grazing rates, food-selection patterns and nutrient mineralization rates of a daphniid cladoceran and a diaptomid copepod to determine their infl uence on phytoplankton composition and the prevalence of N-fi xing cyanobacteria. We show that grazing and nutrient mineralization may act synergistically within a grazer taxon. Cladocerans exhibited non...
At grazing, propagation and scatter become inextricably connected. For sufficiently low source/observer heights, free-space inverse-distance propagation no longer applies and plane-wave descriptions of scatter give way to surface-wave modes. Concepts like surface radar cross section must be reinterpreted; lack of awareness of these facts in attempts to correlate measurements with grazing-angle ...

Grassland desertification by grazing and the resulting micrometeorological changes in Inner Mongolia
Overgrazing is one of the most primary causes of desertification in semi-arid zones of China. From 1992 to 1994 we conducted a grazing experiment in Naiman (lat. 42◦58′N, long. 120◦43′E, 345 m asl), Inner Mongolia, China to elucidate desertification mechanisms. Our experimental field, which was covered with some short grasses, legumes and forbs, included four plots where grazing sheep numbers d...
