Abstract
Erratum to: Calves gastrointestinal nematodes and Eimeria prevalence and associated risk factors in dairy farms, southern Ethiopia Maireg Hailu1, Kassahun Asmare2, Endrias Zewdu Gebremedhin3, Vincenzo Di Marco Lo Presti4, Maria Vitale4, Desie Sheferaw2 On page 6 of the original publication, a short paragraph and a table (the second Table 4) were wrongly included from other article during layout preparation. Therefore, this wrong information has nothing to do with the topic and is deleted from the original publication Abstract: Dairy production is an important component of livestock farming in Ethiopia. Nevertheless, the productivity of the sector has been impacted negatively by the morbidity and mortality of replacement animals. A Cross-sectional study was, therefore, aimed at estimating the prevalence of Nematode and Eimeria infection in calves in Hawassa, Shashemene and Arsi Negelle, southern Ethiopia. To this end, a flotation technique was used to recover Nematode egg and Eimeria oocyst from rectally collected faeces. The overall prevalence of gastrointestinal parasitic infection, Nematode and Eimeria species collectively, was 43.9% (95% CI=38.6-49.4). The estimated proportion of Nematode, Eimeria and mixed infection was 35.8%, 21.5% and 13.3%, respectively. Among the potential factors considered faecal consistency, age and study area were found to increase recovery of Nematode egg and Eimeria oocyst in faeces (p< 0.05). Area wise, the prevalence has been noted to be higher at Arsi Negelle followed by Hawassa and Shashemene (p< 0.05). Besides, younger and diarrheic calves were found more infected by Nematode and Eimeria species than their adult and non-diarrheic counterpart. Based on their morphological appearance, Strongyle type (20.3%), Trichuris (4.2%) and Ascaris (16.3%) eggs, Eimeria oocysts (21.5%) were observed. In the light of this finding, the authors would like to advise the need for strategic intervention.
