Anthelmintic treatment (A), feed supplementation (F), anthelmintic and feed supplementation (A+F) or traditional management (Control) was given to 166 pregnant female donkeys in three localities (Holetta, Debre Zeit and Adami Tulu) in Ethiopia during an on-farm study. Treatments started during the last trimester of pregnancy and continued until 6 months after parturition when the foals were weaned. The same treatments were administered to foals once they reached 1 month of age. Live weights of adults and foals were measured throughout the study along with work output of adult donkeys and survival to weaning of the foals. Faecal worm egg counts (FEC) and blood packed cell volumes (PCV) were recorded monthly. When applied alone, anthelmintic treatment (A) or feed supplementation (F) had no significant effect on live weight gain or foal survival. However, when combined, anthelmintic and feed supplementation (A+F) significantly (p<0.05) improved both live weight gain in adults and foals and foal survival. Workout was not affected by any of the treatments. Treatments A and A+F resulted in a highly significant (p<0.001) reduction in FEC in all three localities during the course of study and for at least 6 months after the last dose of anthelmintic in one of the study areas (Holetta). None of the treatments had any significant effect on PCV. Donkey owners in Ethiopia should be encouraged to adopt both anthelmintic treatment and feed supplementation if they expect tangible benefits in animal performance.
在埃塞俄比亚三个地区（霍莱塔、德布雷齐特和阿达米图卢）进行的一项农场研究中，对166头怀孕母驴给予驱虫治疗（A）、饲料补充（F）、驱虫和饲料补充（A+F）或传统管理（对照）。治疗在妊娠晚期开始，持续到产后6个月幼驹断奶时。幼驹一旦达到1月龄，就给予相同的治疗。在整个研究过程中，测量成年驴和幼驹的活重，以及成年驴的工作产出和幼驹断奶时的存活率。每月记录粪便虫卵计数（FEC）和血液红细胞压积（PCV）。单独应用驱虫治疗（A）或饲料补充（F）时，对活重增加或幼驹存活率没有显著影响。然而，当两者结合时，驱虫和饲料补充（A+F）显著（p<0.05）提高了成年驴和幼驹的活重增加以及幼驹存活率。工作产出不受任何一种治疗的影响。在研究过程中，治疗A和A+F在所有三个地区均导致FEC高度显著（p<0.001）降低，并且在其中一个研究地区（霍莱塔）最后一剂驱虫药后至少6个月内也是如此。没有一种治疗对PCV有任何显著影响。如果埃塞俄比亚的驴主人期望在动物性能方面获得切实利益，应鼓励他们同时采用驱虫治疗和饲料补充。
