CYDECTIN (moxidectin) is Zoetis's broad-spectrum endectocide for cattle, providing control of internal parasites (gastrointestinal worms, lungworm) and external
What is CYDECTIN?
CYDECTIN contains moxidectin, a second-generation macrocyclic lactone (milbemycin class) derived from Streptomyces cyanogriseus. Moxidectin provides:
Extended Persistence Advantage
CYDECTIN's key differentiator is duration of protection:
Against Ostertagia ostertagi (brown stomach worm):
This extended protection is critical because Ostertagia:
Spectrum of Activity
Gastrointestinal Nematodes:
Ostertagia, Cooperia, Haemonchus, Trichostrongylus, Oesophagostomum, Bunostomum, Nematodirus, Trichuris
Lungworm: Dictyocaulus viviparus
External Parasites:
Cattle grubs (Hypoderma species)
Lice (biting and sucking)
Mites (Psoroptes, Sarcoptes)

Evaluation Questions
Key questions to consider when evaluating CYDECTIN:
- 1. What is our current parasite control strategy? 2. Is extended persistent activity valuable in our grazing system? 3. Have we seen evidence of resistance to other products? 4. What is the economic impact of subclinical parasitism in our herd? 5. Can we justify premium pricing for extended protection? 6. How does our pasture contamination cycle work seasonally?
