Health management of a dairy herd on the Jos Plateau Nigeria. Sahelian goats Trematodes were found with the following frequency: The phenomenon, as described in cattle, is commonly known to occur in sheep in temperate regions Donald et al, cestodee Dinneen et al, ; Michael and recently recognised in tropical Africa.
No significant cesrodes was noted on liveweight between the treated groups and the control in adult sheep ewes and rams. Cestodes Cysticercus tenuicollis was widely distributed among small ruminants in Mali.
Journal of the Victoria Department of Agriculture Advances in Parasitology Cestodes The only larval cestode reported in this study is Cysticercus tenuicollis. This parasitogical survey has shown that they also share the same parasite species bun with different levels of infection.
Gastro-intestinal parasites in small ruminants in Mali: Nematodirus spathiger infection in sheep. No Dicrocoelium was found during the course of the investigation. Sudanese dwarf sheep The results obtained from this survey may not reflect the overall field situation due to a limited sample size from the abattoirs visited. A quantitative evaluation of strongyle eggs was performed using the modified McMaster method. Results and discussion The following strongyle eggs reduction rates were observed following the prime anthelminthic treatment.
In the Sahelian sheep, T.
This decrease coincided with a sharp increase of the adult population suggesting the maturation of the immature worms. These findings suggest that the parasite thrives in a region with higher rainfall. Discussion In the traditional management of animals in Mali, sheep and goats are grazed together.
CESTODE – Definition and synonyms of cestode in the French dictionary
The anthelminthic treatments were as follows: Sahelian goats Based on post-mortem examination, the following nematodes were identified in long-legged Sahelian goats in order of predominance: Together, sheep and goats provide a large portion of the meat consumed and produce a considerable amount of manure, which is of special importance in those areas where cattle are of lesser importance.
Parasitological findings Nematodes Sahelian sheep The following parasites species were recorded from Sahelian sheep in order of predominance: Graber recognised this parasite among native sheep of Senegal. Both animal breeds were owned by small individual households. Prevalence figures are given in Table 1. Sudanese dwarf goats Only two nematode species were found in significant numbers. In Mali, it appears from this study that nodular form of the infection is of greater economic importance with a prevalence rate of 25 to One explanation for the difference in worm burdens and composition in sheep and goats is that the latter they are browsers as well as grazers and, if feeding on scrub high enough, they could cestoeds most of the infective trichostrongyle larvae.
Faecal and visceral examinations from sheep and goats indicated a marked variation in aduptes level of parasitism in livestock raised in different geographic areas. Observation on the aadultes and life history of Gaigeria pachyscelis, Railliet and Henry, The Cestoees Veterinary Journal 5: Both sheep and goats were found to be infested with identical adules species, however, with different levels of infestation.
Mao of Mali showing major rivers and collection sites. Epidemiology Materials and methods Sites of collection In order to obtain adequate numbers of samples from the animals, all collections were made at abattoirs.

Age distribution and the severity of infection with gastro-intestinal parasites. Four trematodes Fasciola gigantica, Dicrocoelium nospes, Paramphistomum spp and Ls sppone larval Cysticercus tenuicollis and three adult cestodes Monezia, Stilesia, and Avitellina were identified. They are kept around cestodss villages during the rainy season and allowed to graze freely away from the villages without herding during the dry season. Le Riche P D et al. These groups were subdivided into three age categories: Southern African Journal of Science Studies done in Senegal Vercruysse,have shown that larvae ingested between October lee December were inhibition-prone, the adult populations resulting from the burden acquired during the previous August.
Galgeria pachyscells Since the first report on the occurrence of the hookworm Gaigeria pachyscelis in sheep and goats in South Africa Orlepp,a wide distribution of the parasite has been reported in tropical Africa. Goats are often the main supply of daily meat in rural areas. There was a relatively high prevalence of G. The dynamics of the host-parasite relationship.
Postmortem examination showed the following prevalence:
