Risk of resistance? YES, resistance of gastrointestinal roundworms to macrocyclic lactones (incl. moxidectin) in ruminants is a very serious and increasing problem worldwide, particularly in sheep and goats. The most affected worm species are: Haemonchus spp, Ostertagia spp /Teladorsagia spp, Trichostrongylus spp, Nematodirus spp, Chabertia ovina.
Resistance of gastrointestinal roundworms to macrocyclic lactones in sheep, goats has been reported in numerous countries. Most cases have been reported for ivermectin, and moxidectin often works well initially against ivermectin-resistant worms. 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.
- Benzimidazoles, e.g. albendazole, febantel, fenbendazole, oxfendazole, etc. Similar or even worse resistance problems than macrocyclic lactones.
- Derquantel: available so far only for sheep in combination with abamectin.
- Levamisole. Resistance to levamisole has been reported in most countries, but is usually less strong and frequent than to macrocyclic lactones.
- Monepantel: available only for sheep & goats in some countries (e.g. Australia, UK & EU, New Zealand). First cases of resistance reported in New Zealand in 2013.
- Salicylanilides (e.g. closantel): effective only against certain gastrointestinal roundworms. Not available in some countries. Resistance to closantel has been reported in some countries.
- Tetrahydropyrimidines (e.g. morantel, pyrantel): effective only against certain gastrointestinal roundworms. Not available in some countries. Resistance to morantel has been reported in some countries.
- Nitroxinil: effective only against certain gastrointestinal roundworms (e.g. Bunostomum spp, Haemonchus spp, Oesophagostomum spp). Not available in some countries.
These alternative products may not be available in all countries, or may not be available as drenches, or may not be effective against all the concerned parasites.
It is highly recommended to periodically check the resistance status of each property performing appropriate tests (e.g. fecal egg counts) under supervision of a veterinary doctor. Such tests are now routinely available for most producers in developed countries.

MOXIMAX Plus Selenium Oral Drench for sheep is a local brand from DALGETY LANDMARK containing generic moxidectin.
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.), although the drench formulation is not effective against most external parasites. It is also less toxic than ivermectin, which makes it possible to use it at higher rates, particularly in long-acting formulations. As all macrocyclic lactones, moxidectin used alone is ineffective against tapeworms and flukes, regardless of the delivery form. Moxidectin is moderately used in livestock and horses, but rather scarcely in pets. It is not used in agriculture.
In ruminants, reducing the amount of feed slows down the exit flow of the rumen and prolongs the time during which the active ingredient remains there and is absorbed. Consequently it is advisable to reduce the access of animals to feed (especially to fresh pasture, not to water) 24 hours before administration. For the same reason, it is better to keep the animals away from food for about 6 hours after drenching. However sick or weak animals should not be kept away from food and fasting animals should have access to water.
