New alternatives for the use of IVOMEC premix in combinationwith IVOMEC injectable to eradicate sarcoptic mange in pig farms
Proceedings of International Pig Veterinary Society 18th Congress, June 27-July 1, 2004, Hamburg, Germany, Volume 2, Page 586, Abstract No. 727
Successful mange eradication using IVOMEC® (ivermectin) Injectable alone or in combination with IVOMEC. Premix has been described. Effective use of a reduced dose of IVOMEC® Premix during a longer treatment period, with the same total dose of IVOMEC. (700 µg/kg) was recently reported; allowing more flexibility to the treatment in the field, and offering new opportunities for mange control and eradication. A mange eradication protocol based on the use of a combination of IVOMEC® Injectable and IVOMEC® Premix was used in a commercial 500 sows farrow-to finish farm following a similar approach as previous studies. Weaned piglets and growers in the pre-fattening period were treated with 70 ?g ivermectin /kg/d during 21 consecutive days. Other classes of animals were treated twice, 14 days apart, by injection or with in-feed ivermectin. The high prevalence of mange before treatment and the efficacy of treatment was confirmed by clinical observation, calculation of the scratching index (SI) and detection of mites in ear scrapings. The results of this study confirmed the efficacy of a 70 µg ivermectin /kg/d treatment during 21 consecutive days in piglets in an eradication protocol under field conditions confirming previous experimental findings (7), as well as successful mange eradication with IVOMEC® Injectable in other treatment regimens.
