The spore counts have risen for Foxton, Moutoa, Waitarere, Levin, Ohau, Manakau, Otaki and Te Horo this week. For the following sites, the counts are still low - Shannon, Ihakara, and Otaki. There is time to prepare for these locations. A non-sentinel site in Waikanae came in at 15,000.
Please refer to the recommendations below for your method of prevention. We will continue to update you weekly with recommendations based on spore counts.
Alpacas - begin feeding zinc pellets now for Foxton, Moutoa, Waitarere, Levin, Ohau, Manakau, Te Horo and Waikanae if you haven't started already. Alpacas are affected by facial eczema at low counts of 10,000.
Bolusing or oral drenching โ Foxton, Moutoa, Waitarere, Levin, Ohau, Te Horo and Waikanae should consider bolusing now if they havenโt already. For other sites, wait until counts are around 20,000.
Water dosing (cattle) โ All sites that have started their zinc should continue according to their treatment plan and increase zinc if you haven't done so already. Waikanae should start Zinc as well. Look to increase every 5-7 days by a quarter. Avoid increasing the amount on very hot days. Commercial properties at all other sites should consider doing pre-zinc blood tests, if not already been done, before spore counts rise.
Pasture spraying โ This needs to be carried out early, before the counts rise. It is best to bring in some grass to see what your counts are doing on your farm. The spray will slow the development of the fungus but must be done before the counts reach 20,000. Pasture needs to be green and growing. Pasture will be safe for 4-6 weeks after.
Feeding a crop โ Crops are generally lower in spore counts. If you have a crop, then saving until counts are a bit higher may be helpful.
Breeding โ Facial eczema tolerance can be selected for using rams or bulls. These tolerant animals can then leave progeny with some tolerance to facial eczema. This is a long-term plan.
