Nematodirus spathiger infection in sheep. Sahelian goats Based on post-mortem examination, the following nematodes were identified in long-legged Sahelian goats in order of predominance: McCulloch B et al.
Fifty acultes out of 70 from the starting of the experiment were analysed for live weight changes. However, research is needed to ascertain the importance of the epidemiology of this parasite in Mali. Galvin 2B. William Heineman Medical Books Ltd. Furthermore, the study showed that from January onwards, as the hypobiotic larvae started to mature, these new adults gradually replaced the older population and seeded the pasture with eggs.
The seasonal prevalence of inhibited development of Haemonchus contortus in sheep in Senegal. However, ewes cestoeds infected all year-round thus serving as the source of contamination for the lambs. When the two animal species were combined for statistical analysis a difference of 6 to 7 kg appeared.
Cooperia pectinata, Cooperia punctata and C. One hundred and fourteen goats out of the at the beginning of the experiment were analysed for the same purpose.
Mao of Mali showing major rivers and collection sites. Due to a limited sample size, the results ccestodes this investigation concerning the dwarf sheep may not reflect the overall field situation.

Journal of the South African Veterinary Association Parasitological findings Nematodes Sahelian sheep The following parasites species were recorded from Sahelian sheep in order of predominance: Since the standard deviations were very high the differences may not be conclusive Table 2. Trematodes and cestodes identified were the same as those in sheep. No Dicrocoelium was found during the course of the investigation.
Sheep, on the other hand, are used in ceremonial festivities throughout the country, providing important trade mainly male sheep between rural and urban areas. There was a relatively high prevalence of G.
Lse following species were identified: Kouyate 1S.
The following nematodes were found in goats in order of predominance: Animals comprised exclusively Djallonke sheep and dwarf goats. Further investigation is needed to adulets the pathology of schistosomes in small ruminants because of increasing reports of damage that the parasite might cause in sheep Vercruysse, Both sheep and goats were found to be infested with identical nematode species, however, with different levels of infestation.
These groups were subdivided into three age categories: Eight flocks of sheep owned by villagers were identified by ear tags and randomly divided into three groups of treatment according to their weight: Sudanese dwarf goats Only two nematode species were found in significant numbers. Trichostrongylus colubriformis Although the genus Trichostrongylus is considered to occur primarily in temperate regions and not thought to thrive during the warm rainy season Grant,results from this study indicate that this species may be of economic importance in sheep in Mali because it is one of the most prevalent species both in the Sudanese and in the Sahelian regions.
Both animal breeds were owned by small individual households. Selection of the abattoirs was based on the number of individual animals slaughtered daily and the probability of obtaining native animals from the various ecological regions of Mali.
Immature stages most of which were at an early stage of development were recorded during the dry season and, thus, probably contributed to the increase of the adult populations during the rainy season.

Other species, such as Moniezia, Avitellina and Stilesia were also commonly associated with sheep and goats. This parasitogical survey has shown that they also share the same parasite species bun with different levels of infection. Studies conducted in Australia also showed that sheep and goats were infected with the same species of worms when grazed together Malins, No statistical analysis could be done of weight data lambs because of the low number of observations by the end of the experiment.
Each month, faeces were obtained from the rectum and submitted to a quantitative parasitological examination using the McMaster modified method. Long-legged sheep and goats are found in the Sahelian regions, and the dwarf breed are found in the Sudanese region of Mali.
