Gastro-intestinal Tract Nematodes of Small Ruminants: Prevalence and Their Identification in and Around Alage, Southern Ethiopia

Abstract

A cross sectional study was conducted in small ruminants kept under extensive management system in and around Alage Agricultural Technical Vocational Educational and Training (ATVET) College from October to May, 2018/19. The objectives were set to estimate the prevalence and types of recovered parasites at genus level and assessment of their association with the animal risk factors. A total of 310 randomly collected fecal samples of small ruminants (206 goats and 104 sheep) were examined by simple floatation. In the study area, the overall prevalence of GIT nematodes in small ruminants was 79.68% (247/310). Species specific prevalence of GIT nematode was 78.2% (161/206) and 82.7% (86/104), goats and sheep, respectively. The result showed the existence of single as well as mixed parasitic infections. Accordingly, higher proportion of Haemonchus in sheep (33.72%) and Trichostrongylus in goats (31.1%) represent single infections while Haemonchus with Trichostrongylus in sheep (5.8%), and Trichostrongylus with Oesophagostomum in goats (4.35%) weremixed parasitic infections. Conversely, Bunostomum and Trichuris appeared to be the lowestin proportions in goats (3.73%) and sheep (2.33%) as a single infection whereas Haemonchus with Bunostomum in goats (0.62%) and Trichostrongylus with Bunostomum in sheep (1.2%), as mixed parasitic infections. Analysis of risk factors (species, age, sex and body condition score) revealed that only sex and BCS had significant association with occurrence of parasitic infection (p < 0.05).. Accordingly, females and those with poor BCS were more likely to have parasitic burden than others (p< 0.05). However, rest of risk factors (species and age group) had no statistical association (p>0.05) for parasitic infection. In general, the occurrences of high prevalence of nematodes in the study area suggest that GI nematodes are major constraints for production and productivity of small ruminants. Therefore, application of strategic control measures is recommended to reduce the impact of nematodes in ruminants in the current area.

Gastrointestinal nematodiasis of goats in Somali pastoral areas, Ethiopia

“…10.4%, Trichostrongles 6.5%, Nematodirus 6%, Oesophagostomum 5.5% and Trichuris Spp. 1.87% which agrees with genera reported from Eastern and Southeastern Ethiopia by ( Belina et al, 2017 ; Moje et al, 2021 ).…”

“…The current study found that the overall prevalence of GINs in goats in the study area was 54.17%, which agrees with prevalence reports of 52.67% from Hararghe, eastern Ethiopia ( Belina et al, 2017 ) and 53.29% from Haramaya, eastern Ethiopia ( Ahmed et al, 2017 ). However, it is comparatively lower than prevalence reports of 78.2% from Alage, Southern Ethiopia ( Moje et al, 2021 ) and 100% nematode prevalence in goats from Nyagatare district, Rwanda ( Tumusiime et al, 2022 ). Similarly, the current study disagrees with prevalence reports of 42.1% in Tullo district, western Hararghe, Ethiopia ( Getachew et al, 2017 ) and 26.6% of GINs prevalence in goats from Damaturu, Yobe State, Nigeria ( Adamu and Kyari, 2023 ).…”

Assessment of The Prevalence and Associated Risk Factors of Gastrointestinal Parasite of Goats in Afgooye District, Lower Shabelle, Somalia

“…e results of this study corroborate with those previous studies done Abdi-Soojeede (2018) that showed a high prevalence of parasitic infections in goats with a percentage of 72.1%). e current nding was slightly lower than that previous studies conducted in di erent areas of Ethiopia, such as 78.2% in Alage (Moje et al, 2021), 76.3% in Central Ethiopia (Moti, 2008), and 82% in Genchi District (Emiru et al, 2013). e current nding, however, was signi cantly lower than those of 86.7% (Mideksa et al, 2016) and 85.22% (Pathak and Pal, 2008) from Ethiopia and India, respectively.…”

Prevalence of Gastrointestinal Parasites of Sheep and Goats in An- Lemo, Hadiya Zone Southern Ethiopia

“…This study revealed that the prevalence of gastrointestinal (GI) parasites small ruminates were 77.88%, and 70.28% in sheep and goats, respectively. These results were markedly lower than with the results of (11,(15)(16)(17)(18)(19)(20)(21)(22)(23). They have reported a prevalence of 96.38 % in goats of Ogaden rangelands, 90.41% and 82.13% in sheep and goats in and around Wolayita Sodo, 88.1% and 84.32% in sheep and goats in and around Mekele, 91.43% in sheep in and around Kombolcha, 90.94% and 94.85% in sheep and goats of Gonder, 100% in Boer goats at Adami Tulu agricultural research center 92.23% and 94.1% in sheep and goats of Mendayo district of Bale, 93.22% and 92.24% in sheep and goats of four Awrajas of Eastern Shoa, 90.23% and 88.33% in sheep and goats of Buno province and 85.79% in sheep in and around Asella respectively.…”
