Influence of genotype and topography on the goat predation challenge under communal production systems
2017, Small Ruminant ResearchCitation Excerpt :Despite their adaptability and abundance, optimum productivity is hampered by large losses from mortality. Kid mortality in extensive got production systems often exceeds 50% (Pandey et al., 1994). Major causes of goat mortality include persistent droughts, extreme temperatures, high prevalence of diseases and predation.
Prevalence and risk factors of gastrointestinal parasitic infections in goats in low-input low-output farming systems in Zimbabwe
2016, Small Ruminant ResearchCitation Excerpt :We observed an increase in FEC and infection from October with a peak in April, which falls into the wet season. These observations were also reported by Pandey et al. (1994) in Zimbabwe. Infections continued into the dry season though the level of infection was low; this could be explained by the continued presence of worms in the host even during the dry season, when environmental conditions preclude the development and survival of their pre-parasitic stages.
The Pathophysiology, Ecology and Epidemiology of Haemonchus contortus Infection in Small Ruminants
2016, Advances in ParasitologyCitation Excerpt :In Pernambuco state, Brazil, Charles (1989) found grazing goats to be continually infected with H. contortus throughout a dry season of several months, but new infections from pastures were largely confined to the rainy season. Where altitude moderates conditions in this zone, however, the seasonal pattern of H. contortus infection also appears to reflect lower winter temperatures (mean monthly minima typically <10°C), with higher worm recoveries than in summer, for example, in Kenya (Allonby and Urqhart, 1975) and Zimbabwe (Grant, 1981; Pandey et al., 1994). Most published reports (Eysker and Ogunsusi, 1980; Fakae, 1990; Fritsche et al., 1993; Gatongi et al., 1998; Sissay et al., 2007; Vercruysse, 1985) indicate that H. contortus survives throughout the dry season as hypobiotic fourth-stage larvae, although hypobiosis appears to be absent or less important if the dry season is short (Agyei et al., 1991; Chiejina et al., 1988; Okon and Enyenihi, 1977; Pandey, 1990).
