Hello everyone!
Hope everything is well with you all and with your sheep. Great to see lambing is underway 😊
A vid of a bit of a special needs sheep with a wry neck, who will no doubt get lots of treats as the years go by!
I thought it a good time to do a few updates and recap the past summer and autumn. I am still working on some healthcare plans and will post about this in the coming 2-3 months. If you are interest please PM me, these will be scheduled bookings from my end so you don’t have to worry about what is due when.
Nasal Bot – a lot of sheep had this over autumn this year, but by now hopefully some are sneezing the larvae out if they weren’t drenched for it. If you don’t know, it’s very common and won’t kill the sheep but will make it uncomfortable for a few months. A Bot fly lays its eggs in the nasal cavity of the sheep, they hatch and develop in there until they are mature. Symptoms include sneezing, snotty noses, shaking its head. Mectins and Closantel drenches are best to deal with this.
Flystrike – another quite bad season for strike, a few common themes are starting to come through more regularly each wet summer we are getting. The main one being how length of wool doesn't always correspond to strike frequency and severity of the strike. More and more sheep that have been shorn within 2-3 months are getting flystrike, the common thread between these cases 99% of the time is that they have not been dipped with a high-quality pour on. Unfortunately, the pour ons available to a small flock holder in small enough quantities are of limited effectiveness. Remember Maggo is an antiquated organophosphate that is linked to cancer in humans with over exposure. It is not a preventative but a treatment. Something like salty water, soapy water, flyspray, iodine etc will do exactly the same thing for all intents and purposes – to stop the strike for a few days to give someone like myself time to get there and sort the sheep out with a permanent solution like shearing and treatment with higher quality safer products. As each wet summer passes, more and more strike can be found in the horn coronets, hoof cavities, folds of skin in fat or wrinkly sheep and pizzles in males.
Barbers Pole. A very very bad season for BP worm. Most of the time overburden is linked to some form of stress. The one stressor that will almost always cause BP overburden in lambs is lack of feed. If this is happening year after year then the only solution that will work is to destock a bit. Go with less sheep than you think you need through the toughest time which is summertime for sheep. Adult sheep don’t normally have a problem with BP worm with a few exceptions – heavily strained skinny ewes where the lambs have sucked the life from it over spring and early summer without enough feed (still quite uncommon and mostly will recover without intervention albeit over a long time), breeds that have not developed toughness to it due to being imported into NZ – like Valais blacknose, young rams younger than 2 during tupping as they stop eating and finally, sheep with a deformed mouth like an overbite, underbite or missing teeth. Drench is important, many drenches don’t work properly on BP worm.
Remember this marking season dock and vaccinate lambs at around 3-4 weeks old average age, followed by a booster 4-6 weeks later. Follow tail length regs.
I’ll be out and about a lot more in the coming weeks as the docking and healthcare work increases in the leadup to the beginning of the shearing season!
Take care out there and see you soon.
