Gastro-intestinal nematodes of sheep and goats in three districts of Kaffa and Bench Maji Zones, Southwest Ethiopia

Abstract

A cross-sectional study was conducted to estimate the prevalence and to identify the genera of gastrointestinal strongyles infecting sheep goats in Chena and Gimbo (Kaffa Zone) and Semen-Bench (Bench Maji zones) districts, Southwest Ethiopia. A total of 800 faecal samples were collected from sheep (n=492) and goats (n=308), and then examined by floatation technique. Positive faecal samples were pooled and cultured and third stage larvae (L 3 ) were harvested and identified. From 800 examined faecal sample 433 (54.1 %) were positive for gastrointestinal parasites eggs. Among the risk factors considered in this study age, body condition and history of previous deworming showed significant (P < 0.05) association with gastrointestinal parasites prevalence. Strongyle type eggs dominated the spectrum of infections, where by 73.1% sheep and 72.8% goats were positive for strongyles infection. From the pooled faecal sample culture seven nematode genera were identified in all the study districts (Chena, Gimbo and Semen-Bench) and both in sheep and goats. These genera include Bunostomum, Chabertia, Cooperia, Haemonchus, Oesophagostomum, Teladorsagia and Trichostrongylus. Among these Trichostrongylus, Bunostomum, Haemonchus and Cooperia were the dominant genera in all the three districts. This study indicated that gastrointestinal parasites were among the serious health problem both in sheep and goats in Kaffa and Bench Maji zones. Further study is required to identify the prevailing parasite species and assess the seasonal dynamics of the gastrointestinal parasites in the study areas and thereby to design appropriate control methods that enable to overcome the existing problem.

Prevalence, species composition, and associated risk factors of small ruminant gastrointestinal nematodes in South Omo zone, South-western Ethiopia

“…As indicated, animals with poor body conditions were more severely infested than animals with medium and good body conditions. This is in agreement with previous scholars’ conclusions from Burie district [ 44 ], Kaffa and Bench Maji zones [ 40 ], Tullu district [ 29 ], and Bedelle [ 45 ]. However, the contradictory conclusion of Dabasa et al [ 33 ] from the Bale zone stated that well-conditioned animals were more prone to GIN infestation than poor and medium-conditioned ones.…”

“…The current study found that adult animals had significantly more GIN infestation than young animals.This might be because young kids concentrate on suckling their ewes and does rather than grazing and/or browsing, which could decrease their exposure to infestation. Similar findings were declared in different parts of Ethiopia [ 33 , 40 ], Malaysia [ 47 ], and Lesotho [ 48 ]. However, other researchers from Ethiopia [ 49 ] and abroad [ 50 , 51 ] contrasted with this finding and discovered a higher prevalence of young animals than adults.…”

“…However, reports by Mohammed et al [ 28 ] from the Gamo Gofa zone and Tesfaheywet and Murga [ 39 ] from Hawassa were inconsistent with current findings that declared a significantly higher prevalence of ovine than caprine. Moreover, Kenea et al [ 40 ] confirmed insignificant infestations among the species from the Kaffa and Bench Maji zones.…”

“…Study in eastern part of Ethiopia stated the prevalence of nematodes in sheep and goats with Haemonchus contortus being the most prevalent followed by Trichostrongylus [ 8 ]. Another study in south west Ethiopia reported that 54.1% of sheep and goats were positive for GI parasite eggs [ 9 ].…”

“…Світова література свідчить, що одна з причин, яка знижує ефективність розвитку вівчарства, -це гельмінтозні захворювання, у тому числі й нематодози травного каналу (Suarez et al, 2009). Широке розповсюдження нематод травного каналу загрожує зростанням чисельності популяції збудників паразитарних захворювань у зовнішньому середовищі та підвищенням ризику зараження тварин й поширенням хвороб на нових територіях (Dhar et al, 1982;Moghaddar, 2008;Kenea et al, 2015).…”
