A Quick Guide
As in the case of treating horses you must be competent to do so before administering animal medicines such as wormers to donkeys. The products selected for use should chosen on the same grounds as you would do so for other equines which means taking in all the factors involved and developing a worming strategy suitable to the environment and pertaining circumstances. Although the range of licensed products for donkeys is more limited than for the horse there is still a range which will enable you to plan over a longer period with out over reliance on any one chemical group whilst remembering that there are products in the above list that have different brand names but are in fact the same active ingredients and certain products will treat for a broader spectrum of parasites when used at higher doses. We are here to helpin fine tuning or organising any such plan.
LUNGWORMS (Dictyocaulus arnfieldi)
Lungworms are white in colour and are between 6 and 10 cm in length.
The lifecycle of lungworms is different to other nematodes as adults settle in the lungs rather than the intestine. Eggs are laid then travel up the trachea, are swallowed and passed out in the faeces. Further development then takes place on the pasture, infective larvae are swallowed by horses or donkeys to further develop into egg laying adults.
It has been remarked that a large percentage of donkeys carry lungworms some research claiming levels as low as 4%, some almost 100%. These are obviously dependent on circumstances where the data was gathered but general thinking seems to be that the actual figure is more like 50%. Donkeys often show no clinical signs of infestation and it is in donkeys where the parasite reaches full maturity. Donkeys do not always develop the symptomatic cough that is seen in horses but if horses are grazed along side donkeys then particular care must be taken to treat for lungworms accordingly with particular attention to foals as they can sustain permanent lung damage if infected
