Determination of Number of Cane Hauling Units Based on Grade Ability Index at New Halfa Sugar Factory, Sudan
No full textThe main objective of this study was to find the adequate number of cane haulage
(transport) units, as a function of grade ability (ability to go up slope). The study was
conducted at New Halfa Sugar Factory, with a cane crushing rate of 5000 tons/day. A
150 hp tractor was used on 1 km hauling route as the most critical grade from the second
main center up to the unloading platform. The route was divided into four sections with
different grades. The grade of each section was measured with surveying equipment. The
road combined resistance, that has to be overcome by the hauling unit, is the sum of the
route grade and the coefficient of rolling resistance. As per literature, the coefficient of
rolling resistance is assumed to be 0.02 for all sections. The tractor was run on different
gear meshes to determine its grade ability at different speeds. The total operation time,
function of gear mesh and road combined resistance were determined and used to
calculate hauling unit production rate. The factory crushing rate was divided by the
hauling unit production rate to get the number of hauling units. Two replicates (route
conditions) were used; namely, treated (stabilized) and non-treated. As a result, the
required number of hauling units was 5 and 6 for treated and non-treated routes,
respectively. Out of 36 gears in the tractor gear box, the number of gears actually used
was 2 and 3 for treated and non - treated routes, respectively. This makes the use of
tractor with standard gear box in cane hauling questionable; a simple gear box with three
or four gear may suffice. The study recommends that similar studies should be conducted
at other sugarcane factories, with different route conditions and crushing rates; and that
the grade ability index be included in tractor test code
Effect of Soil Moisture Content and Irrigation Intervals on Sennoside Content of Alexandrian Senna (Cassia acutifolia L.)
No full textA field experiment was conducted for two consecutive seasons (2003 and 2004)
in the demonstration farm of the Faculty of Agricultural Studies, Sudan University of
Science and Technology at Shambat, Sudan to study the effect of irrigation intervals and
quantity of water on sennoside content of Alexandrian senna leaves and pods. Three
levels of soil moisture content (50%, 75%, and 90% field capacity) and three irrigation
intervals (7, 10, and 14 days) were used for the determination of sennoside content
(Sennoside A and B) of Alexandrian senna (Cassia acutifolia L.). Data were collected on
leaf yield, pods yield, percentage of sennoside content of pods and leaves at flowering
and after fruiting stages. Pod sennoside content was 5.35%, 5.41% and 5.46% during the
first season and 5.07%, 5.43% and 5.35% during the second season for intervals of 7, 10,
and 14 days, respectively. Results showed that the highest quantities of water decreased
the percentage of sennoside content in leaves and pods. The sennoside content of leaves
at the flowering stage was 2.56%, 2.63% and 2.7% during the first season, and 2.49%,
2.52% and 2.51% during the second season. Pod sennoside content was 5.48%, 5.46 %
and 5.28% during the first season, and 5.51%, 5.32% and 5.04% during the second
season for quantities of 50%, 75%, and 90% field capacity, respectively. It was
concluded that lower quantities of water (50% field capacity) increased the leaf sennoside
content significantly than that of the higher field capacity (95%)
Potentialities of Hargel (Solenostemma argel) Extract as a Preservative for Processed Meat
No full textThis study was conducted to assess the effect of hargel (Solenostemma argel)
extract (HE) as a natural preservative in processed meat. Minced meat was processed by
the addition of 0%, 5% and 10% hargel extract, packed in polyethylene bags, refrigerated
and assessed objectively and subjectively at 0. 3 and 7 days post – processing. Data were
collected on pH, peroxide value (PV) and moisture, protein and fat content, total viable
bacterial count (TVC), total coliform (TC), Escherichia coli, Staphylococcus aureus and
psychrotrophic bacteria (PS). Minced meat without HE (0%) had the highest (P≤ 0.05)
moisture content, pH, TVC, TC, E. coli, S. aureus and PS. On the other hand, minced
meat with 10% HE had the lowest PV, TVC, TC, E. coli, S. aureus and PS. Generally,
the bacterial counts decreased with increase in HE concentration. The treated minced
meat, particularly with 10% HE, showed all the indices of shelf life extension.
Incorporation of hargel enhanced processed meat quality in terms of microbial safety and
fat stability, probably HE contains antimicrobial and antioxidant compounds. More
studies are needed to ascertain these findings and assess consumer acceptability of meat
products treated with harge
International Meat Market and the Sudan Future as a Meat Exporting Country
No full textLivestock represents the largest subsector of the Sudanese domestic economy and is a
growing contributor to exports. Sudan is characterized by vast areas of range and
arable land which is either rain-fed or irrigated. Although it has a large population of
livestock estimated to be 103 million heads of which 29.4, 39.1, 30.5 and 4.6 million
heads of cattle, sheep, goat and camel, respectively but, until now by the international
standards is not classified among the main meat producers or exporters! Despite the
expected low cost of the traditional method of animal production, still the prices are
relatively high compared with international prices. In addition, Sudanese meat prices
are constantly fluctuating between seasons and within the year. The main meat
producing countries in the world are China, United States, Brazil, Germany and India,
but the main producers are not necessarily to be the main exporters. A country like
China consumes all the meat it produces and imports more. The main meat exporting
countries are India, Brazil, Australia and the United States. India is the leading beef
exporter in the world. The main meat markets around the world are South – East
Asia, West Asia, North Africa, Gulf countries, Japan, North Korea and U.S.A. The
Global meat prices are affected by a number of factors mainly feed cost and drought.
Meat production in warm climatic zones involves some specific problems that differ
greatly from those encountered in the temperate zones. Therefore, an efficient well
developed production and marketing systems is needed so as to compete in the
international market with countries that producing at the lowest cost and high quality.
Meat quality can be improved by the application of available improved techniques
throughout the processing chain. Range management and genetic improvement are
key factors in any programs aiming at increasing efficiency of production
