Abstract：
Factors influencing parasitosis in cattle in Bangladesh remain inadequately explored, necessitating a comprehensive investigation for interventions and sustainable livestock farming.
We 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.
We 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.
We 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.).
Poor 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.

摘要：
背景：影响孟加拉国牛寄生虫病的因素仍未得到充分探索，需要对干预措施和可持续畜牧业进行全面调查。
目的：我们进行了这项研究，以估计胃肠道寄生虫的患病率和分布，探索他们与一系列小型农场管理实践的复杂关系-medium-,和大型商业农场。
方法：我们在孟加拉国Chattogram区进行了这项研究。我们从不同农场共收集了189份新鲜排泄的粪便样本。我们记录了年龄,品种,挤奶状态,性别,身体状况评分,以及取样动物的驱虫药使用史。我们用直接涂片法处理样本,每个样本一个鸡蛋的鉴定被认为是阳性的。
结果：我们估计了大规模胃肠道寄生虫感染的患病率（52.1％），中等规模(54.5%)，和小规模农场(70.0%)，差异有统计学意义(p≤0.05)。怀孕和泌乳的奶牛，以及土著牛，更有可能有胃肠道寄生虫（p≤0.05）。在各种规模的农场中，主要的寄生虫是吸虫（Paramistostomumspp。和血吸虫病。）和原生动物（Balantidiumcoli和球虫。).
结论：糟糕的农场管理实践，例如没有牧场管理和驱虫方案不足，可能导致在小规模农场观察到的患病率和感染负荷升高。先前驱虫的动物中寄生虫病的增加可归因于对胃肠道寄生虫的驱虫药抗性的发展。实施适当和有效的驱虫策略对于预防胃肠道寄生虫病和减轻驱虫药抵抗的风险至关重要。
