Abstract:
The aim of this study is to assess and contribute to the knowledge of the
epidemiology and spatial evaluation of bovine trypanosomosis in West Kordofan
State during dry and wet season in 2001-2002.Trypanosomosis data from West
xiv
Kordofan State in 2001-2002 were collected, analyzed by using Geographic
Information Systems” GIS”.
A geographic information system (GIS) is an integrates hardware, software, and
data for capturing, managing, analyzing, and displaying all forms of
geographically referenced information. The underlying reason for using a GIS in
an animal health information system is to enable the spatial component of animal
health to be incorporated in the reporting and analysis of animal health data.
Sampling was stratified according to livestock management systems, three
management systems were identified in this survey, the traditional migratory
“TM”, traditional sedentary “TS” and dairy system “DS” .
Cross sectional – single visit prevalence for parasite detection was conducted as
the main activity during dry and rainy season.
Economic studies were conducted to calculate the stocking density and total
biomass in the West Kordofan State.
Database was designed, corresponding tables to data entry and questionnaires
were created in Microsoft Access2003, and queries were made. Geographic
information system ”GIS” functions were used. Maps were produced, and
overlays of different data layers allowed highlighting potential priority areas
were made. Microsoft Excel2007 and Animal Resources Information Systems
”ARIS” software were used in data entry and analysis, graphs –charts and maps
were made.
Total of 911 cattle were examined during dry season and 841cattle during wet
season. Point prevalence rates PPR % of the only detected trypanosomes in this
xv
survey which is T.vivax were calculated in the different seasons, dry season
prevalence appeared as follows: 3.40 %, and during wet season appeared as 2.62
%.
Packed cell volume “PCV” of all animals ± standard deviation “Std” during dry
season was calculated as 25.2±4.6 and during wet season as 32.2±3.0, this
compared to PCV ± Std of infected animals during dry season which was
22.5±20.4 and during wet season was 29.3±k1.6.
Traps were made, 238 Ttabanus flies were caught from Kailk, Abyey, Lagawa,
ElSonoot, Mairum, Mujlad and Kejaira.
Trypanocides usage has been evaluated in the West kordofan, results of this
study indicated that Ethydium bromide was the most trypanocide used in
Abyey , Alfula , Alkhiwi , Almujlad , Babanosa , Kadam , Kailk & Lagawa
which showed 100 % of usage. While, Abuzabad showed 92.1 %, Almarum
was 50%, Alsonoot was 64% & Kejaira 53.8 %.Only the Almarum province
showed 36.7% of Novidium usage. 100 % of Berenil usage was appeared in
Alnuhood and Odyah.
