amphistome infection of goats farmed under resource-poor conditions in south africa.from december 1998 to april 2000, a longitudinal study was conducted of the pooled trematode faecal egg counts of samples collected from goats of resource-poor farmers at rust de winter, gauteng province, impendle, kwazulu-natal province, and kraaipan, north-west province, south africa. the amphistome faecal egg counts followed a seasonal pattem, with an increase in the counts during the warmer months of the year (october to march). this is the first work concerning the seasonal cycling of amphi ...200212625386
diversity and seasonal occurrence of eimeria species in a mixed flock of communally reared sheep and goats in mafikeng in the north west province, south africa.diversity and seasonal occurrence of coccidia in a communally reared mixed flock of sheep and goats at mafikeng, north west province, south africa, was determined between march 2008 and february 2009. faecal specimens were collected directly from the rectum of the animals and the number of oocysts per gram of faeces (opg) determined. the mean monthly opg for goats was significantly higher than that for sheep. higher oocyst counts were observed during the hot, rainy season than during the cold, d ...201021247039
use of scanning electron microscopy to confirm the identity of lice infesting communally grazed goat herds.lice have been described on goats in commercial farming systems in south africa but not from flocks on communal grazing. during a longitudinal survey on the causes of goat kid mortality, conducted in jericho district, north west province, lice were collected from communally grazed indigenous goats. these lice were prepared for and viewed by scanning electron microscopy, and micro-morphological taxonomic details are described. three species of lice were found in the study area and identified as b ...200415373329
an economic analysis of communal goat production.the economic impact of different extension messages used was calculated using enterprise budgeting (gross margin analysis). input data were gleaned from the literature, from participatory appraisals, as well as a field study, spanning 12 months, of small-scale communal goat farming systems in jericho in the odi district of north west province. the number of offspring weaned per annum, as a proportion of does owned, was selected as the desired output for analysis. this study has shown that small- ...200415214690
effect of nematode burden as assessed by means of faecal egg counts on body condition in goats farmed under resource-poor conditions in south africa.a longitudinal study was conducted of the nematode faecal egg counts (fecs) and body condition scores (bcss) of goats of resource-poor farmers at rust de winter, gauteng province, impendle, kwazulu-natal province, and kraaipan, north-west province, south africa. periods of higher fecs occurred from december/january to march/april at rust de winter and at impendle and from january to march at kraaipan. seasonal variations in body condition were evident in the goats at impendle with the animals sh ...200212237143
incidence of haemonchus spp. and effect on haematocrit and eye colour in goats farmed under resource-poor conditions in south africa.the diversity and predominance of nematode genera in goats of resource-poor farmers at rust de winter, gauteng province, impendle, kwazulu-natal province, and kraaipan, north-west province, south africa, was determined by means of a longitudinal study of the nematode faecal egg counts (fecs) and differential third-stage nematode larvae. the animals were bled for haematocrit determination and scored for pallor of ocular mucous membranes using the famacha( copyright) method, an assay for clinical ...200211751007
raising livestock in resource-poor communities of the north west province of south africa--a participatory rural appraisal study.a participatory research model was used in six village communities in the central region of the north west province of south africa in order to achieve the following broad objectives: to obtain information on the challenges owners face in raising livestock in these areas and to evaluate the livestock owners' level of knowledge of internal parasites in their animals. information obtained at participatory workshops clearly indicated a need for improvements in water supply, schools, job creation, a ...200212665130
ixodid ticks on indigenous goats owned by small-scale farmers in four communal grazing areas in south africa.indigenous goats belonging to small-scale farmers in 4 communal grazing areas in south africa were sampled for ixodid ticks during the period september 1991 to may 1993. three of these areas were in the north west province (rietgat, madinyane and bethany), and one in mpumalanga province (geluk). no tick control was practised unless requested by the owners. seven ixodid tick species, of which the majority were immature ticks, were collected from the goats in north west province. amblyomma hebraeu ...200212088070
a primary animal health care approach to treatment and control of flea (ctenocephalides felis) infestation in indigenous goats kept on communal grazing.this paper describes a primary health care approach to an infestation of indigenous goats by the common cat flea, ctenocephalides felis. the flea species was identified using scanning electron microscopy. the infested goats were kept on communal grazing at winterveld in the north-west province. they were penned at night in housing made of wire and corrugated iron. the owner complained that the goats were lethargic. fleas were found on the goats and flea larvae were found in the kraal. haematolog ...199910855818
