Anthelmintic Efficiency Assay for FARANTEL EQUINOS
IN SOME COUNTRIES, FARANTEL EQUINOS IS CALLED FARANTEL.

Paddock horses

Introduction
Infestations with parasites are worse when animals graze in low-lying land with permanent marsh and with a large quantity of animals per hectare. Using animals grazing in these conditions with the intention of assessing the anthelmintic effect of a product is a real test of its efficacy. For this reason, from a group of 22 horses, a mixture of geldings, mares and foals, 10 animals were chosen. They live permanently in a 9 hectare field within which there are 2 hectares of marshland where the animals get their drinking water.

Objective
To measure the ovicide and larvicide efficacy of FARANTEL EQUINOS on the most common parasites of paddock horses.

Materials and Methods

Animals: Five control horses (control group CG) and 5 treated horses (treated group TG). All of them continued living in the same field under the same conditions.

Materials: Veterinary exam gloves, nylon bags, cooling refrigerator for the extraction, conservation and sending of the samples.

Experiment design

  • Timetable of application: The anthelmint was administered to the TG orally on day zero and this was repeated on the 20th day.

  • Timetable for sampling: Samples of faeces where taken from both groups from the rectal ampulla on days 0, 20, 40 and 60.

Parameters: An egg count per gram of faeces (EPG/Eggs per gram) and the typification of the larvae for each of the taken samples.

Results
An increase of total parasites during the 60 days of the trial was observed. This increase (no significant difference) was of 250 EPG between first and last sampling in CG while in the TG the difference was only of 136 EPG. On the other hand, an insignificant difference was observed in the values of the EPG between the two groups throughout the sampling period, basically a reduction from the deviation standard of the TG was observed from the sampling on the 20th day onwards which indicates the action of FARANTEL EQUINOS. Lastly in the CG not only Strongyles larvae but also Oxiurus, Parascaris equorum and Ascaris larvae were observed whereas in the TG only Strongylus spp. eggs where observed.

Conclusion
In low-lying land and with a high density of horses per hectare FARANTEL EQUINOS causes a reduction in the parasite load and in the infective species.

Objetive
To meassure the ovicide and larvicide efficacy of FARANTEL EQUINOS on the most common parasites of stabled horses.

Materials and Methods
Animals: 10 training horses of correct health care. 5 of these were used as control horses (control group CG) and 5 were used as treated horses (treated group TG).

Materials: Veterinary exam gloves, nylon bags, cooling refrigerator for the extraction, conservation and sending of the samples.

Experiment design

  • Timetable of application: The anthelmintic was administered to the TG orally on day zero and this was repeated on the 20th day.
  • Timetable for sampling: Samples of faeces where taken from both groups from the rectal ampulla on days 0, 20, 40 and 60.

Parameters: An egg count per gram of faeces (EPG) and the typification of the larvae for each of the samples taken.

Results
There was an increase of total parasites during the 60 days of the trial of the CG, which was not statistically significant as a result of a wide standard deviation. Moreover, and for the same reason previously expressed, there was an insignificant difference favouring the TG in the values of HPG (figure 1). The CG showed with the sampling on days 20, 40 and 60 individual values which were higher than 1000 EPG while the TG showed individual values not higher than 300 EPG. This result was even more important when taking into account that the parasite load was higher in the TG than in the CG at the beginning of the field test. Only Strongylus spp. larvae where observed in both groups owing to their good state of health.

Discussion
The horses used in this study are regularly wormed with oral Invermectin and so we did not find high parasite loads. But despite this, FARANTEL EQUINOS prevented, on the one hand, the appearance of new types of parasites and, on the other hand, reduced even more the parasite load of the Strongyles (the only species found throughout the study) which strongly persisted for 60 days from the start of the treatment. The decrease was not statistically significant owing to the standard deviation which was very big in the CG.

To conclude, FARANTEL EQUINOS could have a stronger anti-parasite effect than the drug regularly used up to the beginning of the study
