RESISTANCE PREVENTION

Risk of resistance? YES, in gastrointestinal roundworms in sheep (very high), goats (very high) particularly in:

Resistance of gastrointestinal roundworms to macrocyclic lactones in sheep, goats and cattle has been reported in numerous countries. Most cases have been reported for ivermectin, and moxidectin often works well against ivermectin-resistant worms initially. But if moxidectin use continues gastrointestinal roundworms will become resistant to it rather quickly. Based on the very abundant and frequent use of ivermectin and other macrocyclic lactones in livestock (with more-or-less cross-resistance to ivermectin) it must be assumed that resistance of gastrointestinal roundworms to this chemical class will continue spreading and strengthening in the future.

This means that if this product does not achieve the expected efficacy against the mentioned parasites, it may be due to resistance and not to incorrect use, which is usually the most frequent cause of product failure.

COMMENTS

MOXISURE SA Injection for Cattle & Sheep from HORIZON AGRESOURCES with 1% moxidectin is a generic version of CYDECTIN.

Moxidectin is a macrocyclic lactone introduced in the 1990s (by AMERICAN CYANAMID). It is moderately used in livestock and pets, but not in agriculture. Its spectrum of activity is similar to the one of  ivermectin, i.e. basically roundworms and certain external parasites (mites, lice, etc.). As all other macrocyclic lactones moxidectin is not effective against tapeworms and flukes. Moxidectin is generally considered as more potent than ivermectin against gastrointestinal nematodes of livestock, particularly in sheep and goats, and against a few other livestock pests (e.g. sheep scab, cattle ticks, etc.). It is also less toxic than ivermectin, which makes it possible to use it at higher rates, particularly in long-acting formulations. Moxidectin is moderately used in livestock and horses, but rather scarcely in pets. It is not used in agriculture.

There are other formulations for topical (pour-on) and oral (drench) administration, mainly for cattle and/or sheep. So far there are no moxidectin products for use on swine.

Being an excellent antiparasitic, comparable to ivermectin, moxidectin does not control all parasites of livestock. Unfortunately advertising and even the label of some generic formulations in less developed countries often include unsubstantiated claims. To help preventing confusion and misuse it is useful to know that whatever moxidectin 1% injectable used at the recommended dose DOES NOT CONTROL:
