[Comparison of the efficacy of ivermectin in injectable form and as a paste in horses].

This research compared the effectiveness of Ivermectin, a medication for horses, when used as an injection or paste. The study found no difference in efficacy between the two methods, both eliminating 100% of parasites in affected horses.

Study Design

• The study involved fourteen horses that had natural infections of small strongyles, a common type of parasitic worm in horses.
• The horses were divided into three groups for the experiment. The first group received an injectable form of Ivermectin while the second group received it in paste form. The third group received no treatment and served as a control to compare the effects of the treatment with the normal progression of the infection.

Dosage

• The dosage for both the injectable and paste forms of Ivermectin was based on the weight of the horse. In this case, 5 ml of Ivermectin, equivalent to a dose for a 500 kg horse, was administered to each horse in the respective groups.

Evaluation of Efficacy

• The effectiveness of the treatments was assessed through fecal examinations and larval cultures, which were conducted on the day of treatment and on specific days after treatment: day 14, day 28, and day 42.
• Both the injection and the paste forms of Ivermectin showed 100 percent efficacy, meaning they were completely effective in eradicating mature and immature small strongyles in the horses treated.

So in conclusion, the research indicated that both methods of Ivermectin administration – injectable and paste – are equally effective in treating small strongyles in horses.
