Distribution and prevalence of gastrointestinal tract nematodes of sheep at highland and midland areas, Ethiopia

Seasonal Prevalence and Status of Anthelmintic Resistance of Goats’ Gastrointestinal Nematodes, Mirab Abaya, Southern Ethiopia

“…The prevalence of gastrointestinal nematode infection was significantly higher in female than male goats ( p < 0.05). Similar finding is reported from various parts of the country and elsewhere [ 4 , 36 , 40 – 43 ]. This might be due to lose of immunity around parturition and during lactation time in female goats [ 23 , 33 , 38 , 39 ].…”

“…From the 445 goats positive for gastrointestinal nematodes, mild, moderate, and severe infection recorded in 58.7%, 23.6%, and 17.7%, respectively. Under tropical condition, such degree of infection and in similar orders of proportions are commonly reported [ 4 , 40 , 41 , 53 , 54 ]. The management practice by the owners, especially, frequency of deworming, and level of grazing area contamination influence the intensity of infection [ 40 ].…”

“…In spite of huge population and importance of small ruminants, particularly goats, Ethiopia has benefited little from this enormous resource due to a combination of factors such as poor genetic potential, inadequate feed and nutrition, lack of effective veterinary services, traditional system of husbandry, lack of veterinary care, management constraints, and the presence of numerous animal diseases [ 1 , 3 , 4 ]. Among the diseases, gastrointestinal nematodes are the most important and widely spread in the tropical region [ 5 ].…”

Positivity Rate Investigation and Anthelmintic Resistance Analysis of Gastrointestinal Nematodes in Sheep and Cattle in Ordos, China

“…However, the Hangjin Banner and Ejin Horo Banner lack relevant professional training, and herders have little awareness of parasite control. However, the infection rate of GINs in sheep in Ordos is lower than that in Ethiopia (83%) [ 22 ], Bangladesh (77.1%) [ 23 ], South Africa (81%) [ 24 ] and Algeria (96%) [ 25 ]. Although the different breeds, detection methods, geographical differences and sample sizes are factors that may contribute to varying infection [ 26 ], the infection rate of GINs in Ordos is still low.…”

Acute Toxicity and Anthelmintic Effects of &lt;i&gt;Gomphrena &lt;/i&gt;&lt;i&gt;serrata&lt;/i&gt; L. (Amaranthaceae) Extracts on Adult Worms and Eggs of &lt;i&gt;Haemonchus &lt;/i&gt;&lt;i&gt;c&lt;/i&gt;&lt;i&gt;ontortus&lt;/i&gt;

“…Particularly in small ruminants, infestations due to gastrointestinal nematodes constitute a fundamental constraint in breeding [2] [3] because they cause growth retardation and weight loss in these animals [4] [5]. Thus, the parasitic fauna of the digestive tract of small ruminants is dominated by strongyles, particularly Haemonchus contortus (H. contortus), by its frequency and intensity [6] [7] [8] [9].…”
