[2022/03/02, 09:34:51] Gernot Redeke: Good morning. I have a problem in a sable herd - 50 animal in a 50 ha camp. They have a severe Haemonchus worm infestation, 8 animals dead in last 2 weeks. How would I proceed with treatment? [2022/03/02, 10:39:53] Kobus: Morning guys. Any advice for deworming 10 klipspringers in a boma setup. Thank you very much. [2022/03/02, 11:58:36] Paul Reynolds: Is there nowhere to move them to? Reduce numbers and reduce grazing intensity. Better to sell than them than to let them die. Dewormers are running out and resistance difficult to manage when it’s there. For the future of the farm, decrease numbers [2022/03/02, 15:37:54] Heather Nixon: I know this is controversial, but the 2 herds I had a few issues with improved, and did quite well feeding diatomaceous earth. [2022/03/02, 20:32:49] Douw Grobler: Douw I see there is a question regarding Haemonchus treatment on the WildVet WhatsApp. Copper wire boluses work well, especially in resistant herds. Commonly used in US zoological institutions for Haemonchus - there is lots of supportive literature. We have used it for years at the Park and I’m pretty sure Scott uses it at White Oak. There are a few articles of successful use in goats in RSA (Vatta et al), as well. Hope all is well, Douw! Z We use them monthly on problem herds such as giraffe and gerenuk [2022/03/02, 21:22:25] Louis Greeff: Good evening, my 5 cents regarding worms and their treatment Try as far as possible to have two camps. Rotational grazing is your number one management option. Do McMaster egg counts, then you know who the enemy is and how big your infection rate is. Because of the low feed intake ( good rains= good grazing) and social stress in herds, it is much better to deworm through the water. Each animal must drink a certain amount of water each day (on average 0.65 to 0.75l per 10kg per day). There are 3 water-soluble worm remedies on the market that I use in my worm treatment regime: Unidose (Trichlorphon) 2.5ml per 10kg Virbamax LV (Abamectin) 1ml per 10kg Maxicare (Closantel) 2ml per 10kg My regime works as follows: 1. Work out the biomass in the camp :10 Sable cows @ 180kg per cow equals 1800kg 2. Work out the worm remedy dosage for the camp 1800kg / 10 x1 =180 ml Virbamax LV The same can be done for the other two remedies 3. Work out the capacity of the water trough 1mx0.5mx0.4m = 0.2 cubic meters which equals 200l of water 4. Work out how many water troughs of water you need. My regime work as follows: Virbamax LV 1ml per l water Unidose 2ml per l water Maxicare 2ml per l water Thus in this 200l water trough, I would take out 20 l of water and put 180 mls of Virbamax LV in the trough 5. Monitor intake. Usually animals consume the required amount in 2 to 3 days. [2022/03/02, 21:27:32] Louis Greeff: Don't deworm if rainy weather; no other water sources, Unidose is an organophosphate, as is Closantel and lipid bound. if animals are in poor condition, then this can be a problem. In these instances, I use Virbax , wait 10 days, redo worm counts. If they are high, then use Unidose as second treatment. I wait 10 days again, do an egg count, if still high, then I administer Maxicare. This works well in zero grazing setups. I put out salt licks, thus they consume enough treated water. I agree with copper, and diatomaceous earth as potential treatment options. . Good rains have made the problem worse this year. This programme must however be properly managed by the veterinarian. [2022/03/02, 21:43:15] Louis Greeff: You can also use WireVax from Afrivet. I have done two sable herds and one roan herd and it definitely works well, especially where you don’t have the option of rotational grazing [2022/03/03, 07:42:29] Newton Sparks: Louis, what do you do in animals with poor condition and where you have resistance against abamectin?
