“…This results in an early pasture contamination with infective L 3 , as has previously been recorded in Lithuania on pastures grazed by sika deer [37] and goats [38]. The initial aim of the present study was to avoid early pasture contamination by ewes at the start of the grazing season.…”

BackgroundAccording to targeted treatment (TT), the whole flock is dewormed based on knowledge of the risk, or parameters that quantify the mean level of infection, whereas according to targeted selective treatment (TST), only individual animals within the grazing group are treated, based on parasitological, production and/or morbidity parameters. The aim of this study was to compare two different treatment protocols on sheep farms in Lithuania. The study was conducted from 15 April to 31 October 2014 on three sheep farms. On the TT (the whole flock) and T(S)T (with FECs ≥ 300, respectively) farms all adult animals were treated orally with fenbendazole irrespective of EPG counts before the grazing season. The second treatment was applied with injectable ivermectin on both farms. However, on the TT farm all sheep were also treated on 2nd August regardless of their EPG counts, while on the T(S)T farm only those animals with an EPG ≥ 300 were treated on 1 July using a threshold of ≥ 300 EPG. No treatments were administered on the control farm (n = 1) during the study.ResultsSpring treatment of ewes significantly reduced nematode faecal egg counts (FEC) both on the TT and T(S)T farms, with the benefit of lowering pasture contamination with infective L3 stage larvae at the start of grazing season, while it remained significantly higher on the control farm. The positive effect of the spring treatment of ewes was reflected by increased body weight gains (BWG) in lambs in the first half of the grazing season. Following the second treatment, the weight gains in lambs on the T(S)T farm were higher compared to lambs on the TT farm, while BWG in the control lambs started to decrease. The difference was also substantiated by the body condition scores (BCS) and dag scores (DS) of lambs, which were highest on the T(S)T farm compared with those on the control and TT farms.ConclusionsThe results of this study show that both treatment strategies were useful in reducing clinical effects (BCS and DS) of gastrointestinal nematode parasitism and increasing the performance in lambs. Furthermore, on the T(S)T farm some of animals were left in refugia, helping to slow down the development of anthelmintic resistance (AR) in future.

“…A previous study in Nepal, a neighbouring country of Bangladesh, has also indicated similar risk factors (Yadav et al., 2015 ). Furthermore, in Bangladesh, cross‐bred cattle are predominantly reared in commercial farming systems utilizing zero‐grazing techniques, which could potentially act as a protective factor against parasitosis (Stadalienė et al., 2014 ). It is surprising that dewormed cattle had significantly higher odds of GIP infection, which could be due to having developed anthelmintic resistance against GIPs.…”

BackgroundFactors influencing parasitosis in cattle in Bangladesh remain inadequately explored, necessitating a comprehensive investigation for interventions and sustainable livestock farming.ObjectivesWe conducted this study to estimate the prevalence and distribution of gastrointestinal parasites, exploring their intricate relationship with farm management practices across a spectrum of small‐, medium‐, and large‐scale commercial farms.MethodsWe conducted this study in the Chattogram district of Bangladesh. We collected a total of 189 freshly voided faecal samples from different farms. We recorded the age, breed, milking status, sex, body condition score, and anthelmintic use history of the sampled animals. We processed the samples using the direct smear method, with the identification of one egg per sample being considered positive.ResultsWe estimated the prevalence of gastrointestinal parasite infection in large‐scale (52.1%), medium‐scale (54.5%), and small‐scale farms (70.0%), with statistically significant differences (p ≤ 0.05). Both pregnant and lactating cows, as well as indigenous cattle, were more likely to have gastrointestinal parasites (p ≤ 0.05). The predominant parasites across farms of all sizes were trematodes (Paramphistomum spp. and Schistosomas spp.) and protozoa (Balantidium coli and Coccidia spp.).ConclusionPoor farm management practices, such as no pasture management and inadequate deworming regimens, may contribute to the elevated prevalence and infection load observed on small‐scale farms. The increased parasitosis in previously dewormed animals can be attributed to the development of anthelmintic resistance against gastrointestinal parasites. Implementing proper and effective deworming strategies is crucial to preventing gastrointestinal parasitosis and mitigating the risk of anthelmintic resistance.

“…21,22 These parasites negatively impact the output and quality of milk and can also result in stunting, death as well as in condemnation of organs at slaughter. 12,23,24 Goats are susceptible to different gastrointestinal helminths (nematodes, trematodes, and cestodes) and protozoa. 25 STNs (Haemonchus contortus, Cooperia curticei, Trichostrongylus spp, Oesophagostomum columbianum, Teladorsagia circumcincta, Bunostomum trigonocephalum, Nematodirus spp) cause major caprine helminthiases.…”

Goat farming significantly contributes to the efficient use of land and socioeconomic development in developed and developing countries. During the fiscal year 2017-2018, goats made up 13.5% of the total live livestock exported by Rwanda. Gastrointestinal parasites (GIPs) can negatively impact goat production, especially in developing countries like Rwanda. This study aimed to determine the impact of the goat' age and location (administrative cell) on the prevalence of gastrointestinal nematodes, cestodes, and protozoans (GiNCPs) of goats in Nyagatare district, Rwanda. Methods: In this cross-sectional study, 149 faecal samples were collected from apparently unwell goats and analyzed using the simple flotation technique. Strongyle-type nematodes (STNs) infections were graded using the McMaster method. Pearson chi-square tests of independence were calculated to assess the impact of the goat' age and location on the prevalence of GiNCPs in the study area. Results: All the goats (100%) were infected with GiNCPs. The identified types of parasites were STNs (96.0%), Coccidia (83.2%), Moniezia spp (14.8%), Strongyloides papillosus (12.8%), Nematodirus spp (0.7%) and Trichuris ovis (0.7%). Nearly 85.9% (128/149) of the goats were coinfected with 2 to 4 types of parasites and the coinfection of STNs and coccidia preponderated at 58.4%. The location (administrative cell) of the goats correlated with the prevalence of monieziasis (p<0.05). The goat's age category was also associated with the prevalence of strongyloidiasis (p<0.05). Conclusion: All the goats (100%) were infected with GiNCPs. The location (administrative cell) of the goat also correlated with the prevalence of monieziasis. In addition, the goat's age category was associated with the prevalence of strongyloidiasis. These findings show that any control program for caprine gastrointestinal parasitoses in the study area should focus on STNs and Coccidia.
