“…The uneven uptake of medication by individuals when sprinkled over food, as most institutions prefer to do, is a well‐recognised problem that limits treatment success as well (63 per cent; CI ±15) 48 49 .

Survey of husbandry practices for bovidae in zoos: the importance of parasite management for reintroduction programmes

et al. 2019

Animals from zoological institutions may be used for reintroductions. These individuals are considered healthy, but they are not necessarily free of parasites, despite the minimum husbandry standards required of zoological institutions as described in the European Association of Zoos and Aquaria guidelines. In this sense, parasitism has been identified as the cause of failure, or has added difficulties, in some reintroduction programmes. Here the authors attempt to summarise the risk of parasitism to animals originating from zoological institutions by analysing a questionnaire about parasite prevalence, sampling methods, treatment and control in three ungulates in European zoos. Completed questionnaires were received from 38 institutions (58.5 per cent response rate). Most of the responding institutions (97 per cent) detected the eggs of endoparasites in faeces, but only one reported ectoparasites. Most institutions followed a similar preventive schedule, with ivermectin as the preferred prophylactic treatment for parasites, commonly administered in food every six months. The frequent use of concentrating flotation techniques as the sole method to evaluate the presence of parasite eggs in faecal samples is not recommended because it fails to detect trematode and lung nematode infections, so it would be better to use flotation techniques together with sedimentation procedures or serological and molecular tests. The results suggest that parasite control in zoological institutions can be complicated, indicating the need to implement a specific management schedule for institutions involved in reintroduction projects.

In Algeria, sheep farming is still largely traditional, and ewes are subject to various pathologies, particularly parasitic diseases leading to reproductive failure and production losses. To assess the influence of internal parasites (helminths and protozoa) and their interaction with the different phases of reproduction and season on hematological parameters, fecal and blood samples (n = 89) were taken from ewes during the period from the end of gestation to 3 months after parturition, two weeks apart. Animals were reared under a traditional pasture–based farming system in a Region of Northeastern Algeria characterized by a Mediterranean climate. Parasitic coproscopy results showed the consistent presence of digestive strongyles, Strongyloides, Trichuris ovis, Moniezia spp., Fasciola hepatica, and Coccidia. Hematological parameters, mainly hematocrit (HCT), hemoglobin (HGB), and erythrocytes (RBC), showed lower levels in anemic ewes throughout the study period. These hematological effects became significantly prevalent in 91% of the animals (P<0.05) during the third month postpartum (p.p.). The use of a mixed–effects model confirmed the significant hematological effect (P<0.05) of internal parasitism, which was amplified significantly by its interaction with the reproduction stage for HCT and RBC (P<0.01). Monitoring of blood biological constants in ewes during the critical reproductive stages seems to provide valuable data to improve their welfare and resistance to potential internal parasites.

“…Tissue larvae resume activity and development in ewes in synchrony with the lambing season, causing a peri-parturient increase in fecal egg counts (FECs), contaminating pasture with L 3 stage that infects the animals while grazing (Roeber et al, 2013). Hypobiotic larvae infect animals causing clinical manifestations (Meradi et al, 2016). Gold standard diagnosis is microscopic examination (McHardy et al, 2014).…”
