“…The observed high FEC during the rainy/late rainy season and the lowest egg counts observed during the dry season concur with studies in other tropical countries with distinct wet and dry seasons (Moyo et al 1996;Waruiru et al 2001;Keyyu et al 2005). The conditions that favour rapid grass growth also favour parasite larvae growth.…”

The objective of the study was to determine monthly changes in body condition scores, body weights and on the prevalence of internal parasites in Nguni, Bonsmara and Angus steers raised on sweetveld. Body condition scores (BCS), body weights (BW), packed cell volume (PCV) and monthly faecal egg counts (FEC) were determined in 25 Nguni, 15 Bonsmara and 15 Angus steers. Nguni and Bonsmara steers maintained their body condition throughout the study, while the Angus lost condition. The Nguni had the highest PCV levels. The PCV levels tended to decline during the rainy season for all the breeds. The FEC were generally low. Fasciola spp. and strongyle eggs were found in 16.3 and 54.6% of the collected faecal samples, respectively. Of the three breeds, Nguni steers had the lowest parasite infestation levels, with the Bonsmara being more susceptible than the other two breeds. Generally, the egg counts observed throughout the study were low.

“…Farmers should be educated on the importance of using personal pasture and dry season feed reserves as means to ensure safe feed for zero-grazed cattle. The high prevalence of £ukes and GI nematodes in traditional cattle concurs with studies in other tropical countries (Kaufmann and P¢ster, 1990;Anene et al, 1994;Moyo et al, 1996). The high prevalence might be a re£ection of the management practices; dairy farms had improved management with routine anthelmintic treatments that may have reduced the prevalence and burdens compared to traditional farms.…”

Cross-sectional Prevalence of Helminth Infections in Cattle on Traditional, Small-scale and Large-scale Dairy Farms in Iringa District, Tanzania

A cross-sectional study was carried out to determine the prevalence of gastrointestinal (GI) nematodes and flukes (Fasciola and amphistomes) infection in communally grazed traditional cattle, zero-grazed small-scale dairy cattle and intensively grazed large-scale dairy cattle through examination of helminth eggs in faeces. Results indicated that the type of management, especially the grazing habit, has a significant influence on the prevalence and intensity of GI nematodes and flukes. The prevalence of GI nematodes in traditional, large-scale dairy and small-scale dairy cattle was 67%, 44.4% and 37%, respectively, with the highest faecal egg counts in calves. The overall prevalence of Fasciola gigantica in traditional, large-scale dairy and small-scale dairy cattle was 63.8%, 46.2% and 28.4%, respectively. The prevalence of amphistomes was 81.9%, 55.5% and 41.1% in traditional, large-scale dairy and small-scale dairy cattle, respectively. The high prevalence of flukes in the traditional system was attributed to communal grazing and watering management practices. Stomach flukes recovered in examined cattle at the abattoir were Calicophoron microbothrium and Cotylophoron jacksoni. About 42.1% of infected animals had both Fasciola and amphistomes. The prevalence of both GI nematodes and flukes varied greatly among villages and farms. The prevalence of both Fasciola and amphistomes was higher in adults (58.5%, 75.2%) than in yearlings (36.5%, 51.5%) or calves (24.9%, 47.2%). The variation in the prevalence of both GI nematodes and flukes among management and age groups within systems can be used as an entry point towards rational use of anthelmintics for each management system. More studies on seasonal transmission pattern of all these parasites are required in order to design rational, economic and locally sustainable parasite control programmes.

“…Dunn (1978) reported that during late pregnancy the dams become stressed, releasing prolactin, which stimulates the hypobiotic L 4 and that even emergent adults from L 3 acquired during early rains to become fecund and have their full reproduction potential. Haemonchus are able to perpetuate themselves through hypobiosis in harsh climates (Hammond & Sewell, 1993; Moyo et al ., 1996). The high prevalence of Haemonchus eggs in faecal droppings of impala in April, October and November could be an indication of such adaptive strategies.…”

The study was done in Lake Mburo area, Uganda, consisting of Lake Mburo National Park and surrounding ranches. The study involved monitoring changes of output of helminth eggs per gram (e.p.g.) by impala for 12 months. Fresh faecal samples, 178 in total, were collected from the rangeland and subjected to floatation and culture tests. There was a peak faecal e.p.g. output from March to April and from October to November. This period coincided with time of high rainfall and calving peak of impala. There was no faecal e.p.g. observed during the dry spell from June to July.
