Item The Digestible Energy Content of Some East African Grasses(1967) Marshall, B.; Long, M.I.E.Digestible energy values are presented for nine grasses and hays. The experimental results are compared with results calculated by means of various published equations. One of these produces results averaging 2.5 per cent below the levels determinedItem The Mineral Status of Beef and Dairy Farms in Acholi and Lango Districts, Uganda(1976) Ndyanabo, W.K.; Marshall, B.; Pratchett, D.; Animal Health Research Centre, P.O. Box 24, Entebbe, UgandaThe mineral status investigations were carried out on cattle blood plasma and herbage samples twenty-four sites on twenty-two farms in Acholi and Lango districts from which collections took place during 1969 and 1970. Blood plasma was analyzed for calcium, magnesium and inorganic phosphorus while for the herbage samples, nitrogen, sodium, potassium, calcium, magnesium manganese and phosphorus levels are reported.Item The Mineral Status of Beef and Dairy Farms in Acholi and Lango Districts, Uganda(1976) Marshall, B.; Pratchett, D.; Ndyanabo, W.K.; Animal Health Research Centre, P.O. Box 24, Entebbe, UgandaSince 1962, the Department of Veterinary Services and Animal Industry in Uganda has carried out series of surveys intended to establish the levels of minerals present in pasture herbage, soils from the pastures and bovine plasma of dairy and beef cattle grazing such pastures. This paper reports the results of soil analysis and describes Acholi and Lango districts of Uganda in which the survey was carried out.Item Selective Consumption by Stall-Fed Cattle and Its Influence on the Results of a Digestibility Trial(1962) Bredon, R. M.; Marshall, B.The selective consumption of roughages by stall fed steers was investigated and the results are compared with some published figures. A digestibility trial with Panicum maximum hay using 6 Zebu steers was carried out and the effect of selective consumption on digestibility coefficients, digestible nutrients and accuracy of techniques is discussed. The results show that the animals were able to select certain parts of the roughages and that the eaten portions were superior to those offered.Item Small-scale fish meal production under tropical conditions(1954) Marshall, B.; Bredon, R. M.; Animal Health Research Centre, Entebbe, UgandaAt the present time there is a world shortage of protein which affects both the human population and its livestock. This shortage is very pronounced in Uganda, where the principal locally grown foodstuffs are of a starchy nature, and, since the intake of food by humans or animals is limited by bulk, these foods cannot supply sufficient proteins for normal requirements. Certain amounts of meat, fish, beans and groundnuts are consumed, but the supply is far below the need. There is, however, a considerable waste of protein-rich food from the fish industry, which consists of unsaleable fish and fish offals. The consumption of fish by the Uganda population is greatly influenced by taboo and local taste, and because of this the demand for various species of fish varies from one district to another. The climatic conditions and the difficulties of transport make the distribution of fresh fish expensive.Item Variation of Esophageal Fistula Samples Between Animals and Days on Tropical Grasslands(1968) Bredon, R.M.; Torel, D.T.; Marshall, B.Forage collected by esophageal fi stulated cattle varies in chemical composition between days and animals. The' number of samples needed for a given degree of accuracy was determined. Silica content of fistula steer feces was significantly different from feces from the non-fistulated steer. There were no significant differences in crude protein, crude fiber, and ether extract.
