Deworming

As we have dewormed our 4-footed friends 24 hours ago, it was time to investigate what kind of "internal life" were they growing since mid-July when we did it last time?

There were some feces with no findings at all:


But most of them contained from one up to three bots:


Which is quite usual, as bots are principal "guests" of our horses intestines from the times immemorial.  Well - you see, they can fly when adult, so we can do little to prevent such visits!

But, their number is high in fact. I can't explain this. The frequency of their appearance in feces we have inspected this morning is at least two times higher than in July. We have used invermectin this time, being alarmed by Petra, who has dewormed Madeshir and Gelshah earlier.

It looks like we should deworm our herd more often next year. For the time being, we used to do that twice a year, with each change of the pasture (which was usually in July when, after collecting hay, we have moved the herd from the First Pasture to the Great Pasture and in November or December, when the grazing season was near the end and we have moved the herd to the Winter Paddock).

However, if bots are concerned, we can do that any time, as bots die when defecated, so there is no risk of secondary infestation after deworming horses and keeping them at the same place. Therefore, we plan to change our habit and deworm our friends in June, September and December next year.

Note, that this year wasn't particularly wet and warm (which usually enhances all kinds of infestation), we have had no new horses in our herd (except for newly born) and there was no unusual concentration of other animals (cows mostly) near our farm. Everything was like a year ago or two years ago...

Except for one thing only! This year we met unpaired with any previous experience number of Ixodidae here, in Boska Wola.


Normally, we have found one or two of them yearly. This autumn we used to find one or two each week. And mostly - on our foals furs.

What is a common environmental cause of Ixodidae and Gastrophillus plagues..? I don't know. Maybe some of you has any idea about that..?

If we should go back to the question of water, then the only difference I find between this year and the previous years here in Boska Wola, is the scale of beavers activity on a nearby drainage channel. This year the level of water there is, regardless the weather, at least a meter higher than previously.

But this is some half a mile away from our nearest pasture..?

  1. You need to deworm your horses when you notice parasites, otherwise you risk resistances. If you decide to deworm on a regular basis you have to alternate deworming agents to lower the risk of resistances. Plus you need Praziquantel against flatworms, they are resistant against Ivermectin.
