The main objective of this study was to assess the gastrointestinal parasitism in relation with the worm control practices (WCP) in dairy cattle in areas of major importance for dairy/milk production of Cameroon.
Fresh fecal samples were randomly collected from 402 cattle from August to October 2016 in North West Cameroon, and analyze using the McMaster technique. Data on WCP were collected using a questionnaire.
A total of 11 parasites species were identified: Trichostrongylus sp. (5.97%); Oesophagostomum sp. (5.47%); Haemonchus sp. (2.48%); Bonostomum sp. (1.74); Cooperia sp. (1.49%). Toxocara sp (0.24%); Ostertagia sp. (0.50%); Nematodirus sp. (0.74%); Trichuris sp. (0.50%); Moniezia sp. (0.50%); Eimeria sp. (0.50%). The mean individual parasite load for helminthes and protozoa ranged from 100 to 400 eggs per gram of feces (epg) and 333-400 oocysts per gram of feces (opg), respectively. Most farmers (95.12%) used conventional drugs (Albendazole, Doramectin, Fenbendazole, Ivermectin.) to deworm animals as compared with traditional phytotherapy (e.g., Carica papaya leaves) (4.88%). The mean epg/opg in animals treated with conventional drugs was significantly higher (p < 0.05) than in those receiving traditional treatment. Animals treated less than four times a year with conventional drugs had the highest (p < 0.05) mean epg/opg compared with animals treated four to six times a year.
This study suggests that treating at least four times a year with conventional drugs, and at least two times a year with traditional approaches could help reducing GIP burden in dairy cattle in North West Cameroon. Since the majority of farmers use conventional drugs, it is imperative for them to appropriately use these conventional drugs for a better control of GIP on their farms.
本研究的主要目的是评估与喀麦隆主要牛奶生产地区奶牛的驱虫实践（WCP）有关的胃肠道寄生虫感染。
2016 年 8 月至 10 月期间，在喀麦隆西北部，从 402 头奶牛中随机采集新鲜粪便样本，并使用麦克马斯特技术进行分析。使用问卷收集有关 WCP 的数据。
共鉴定出 11 种寄生虫：旋毛虫属（5.97%）；食道口线虫属（5.47%）；血矛线虫属（2.48%）；比雄线虫属（1.74%）；库珀线虫属（1.49%）；弓首蛔虫属（0.24%）；奥斯特线虫属（0.50%）；新蛔虫属（0.74%）；毛首线虫属（0.50%）；莫尼茨绦虫属（0.50%）；艾美尔球虫属（0.50%）。蠕虫和原虫的个体寄生虫负荷均值范围分别为每克粪便 100-400 个虫卵（epg）和每克粪便 333-400 个卵囊（opg）。与传统植物疗法（例如木瓜叶）相比，大多数农民（95.12%）使用常规药物（阿苯达唑、多拉菌素、芬苯达唑、伊维菌素）驱虫动物（4.88%）。用常规药物治疗的动物的平均 epg/opg 显著高于（p<0.05）接受传统治疗的动物。每年用常规药物治疗少于 4 次的动物的平均 epg/opg 明显高于每年治疗 4-6 次的动物（p<0.05）。
本研究表明，每年至少用常规药物治疗 4 次，每年至少用传统方法治疗 2 次，有助于减轻喀麦隆西北部奶牛的 GIP 负担。由于大多数农民使用常规药物，他们必须正确使用这些常规药物，以更好地控制其农场的 GIP。
