Description
Cydectin Injection for Cattle contains 10 g/L moxidectin, a second-generation macrocyclic lactone (ML) endectocide for the treatment and control of moxidectin-sensitive internal and external parasites in cattle. Because moxidectin is the most potent active in the ML drench class, it kills worms that have developed resistance to ivermectin, doramectin, and eprinomectin, giving producers a reliable step up in efficacy when first-generation ML options lose ground. Virbac (Australia) Pty Limited supplies this product as a low-volume, non-irritant injectable that flows readily through standard applicator equipment.
Cydectin Injection for Cattle also delivers significant persistent activity after a single subcutaneous dose. It prevents re-infection with Ostertagia ostertagi for not less than 21 days, with Dictyocaulus viviparus (lungworm) for not less than 35 days, and with Haemonchus placei (barber’s pole worm) and Trichostrongylus axei for up to 14 days. Furthermore, the product prevents the development of viable cattle ticks for 28 days after treatment and is safe to use in all ages and breeds, including pregnant females and breeding bulls.
