I am interested in purchasing the Ivomec PLUS injectable for Cattle. But notice the highlighted part. So I was wondering if this is safe for my does. It has been extra wet this year and I am concerned about liver flukes as you can't see them in a fecal. So I was thinking that a once a year treatment with this would be a good idea :? Ivermectrin 1% and Clorsulon 10% (Merial) Only IVOMEC® Plus wormer kills more types of parasites in a single dose, including internal AND external parasites AND liver flukes. Administer 1 ml per 110 lb body weight SQ only. Not approved for use in female dairy cattle of breeding age. 56-day slaughter withdrawal for cattle. Parasites controlled include: Liver flukes Gastrointestinal roundworms Lungworms Grubs Sucking lice Sarcoptic and Psoroptic mange mites IVOMEC 1% and IVOMEC Plus are active against (Dictyocaulus viviparus) and (Ostertagia ostertagi) for 21 days after treatment and (Haemonchus placei), (Trichostrongylus axei), (Cooperia punctaia), (Cooperia oncophora) and (Oesophogostomum) radiatum for 14 days after treatment in cattle.
