Controlling Haemonchus in Australian Goats

06/05/2024

For those who are having a go with Bioworma ☺️

When can you stop feeding BioWorma?
You don't need to feed BioWorma if it is too cold for the worm eggs to hatch, so no worm larvae for the fungus to eat. However the definition of too cold varies with the species of worms you have on your farm. If you have barbers pole worms (Haemonchus) then eggs stop hatching if the daily maximums drop below 18 C . If you have Trichostrongulus (black scour worms) it is when daily maximums drop below 15 C or 12C depending on the species. If you have Teladorsagia (brown stomach worms) then daily maximums must drop below 8 C before the eggs stop hatching. See https://wormboss.com.au/roundworms-2/worms-on-pasture/

📣 Do you want to maximize the effectiveness of your "drench" and ?

When treating your goat with an anthelmintic product, DO NOT treat all goats in the mob! 🐐 This increases the risk for "drench" resistance 🧬(a parasite's ability to genetically mutate and survive chemical treatment).

17% of study participants left at least 10% of the mob untreated.😿

Instead, use your evidence gathering tools (see previous posts) to select affected individuals that require treatment.

We know you love your , so make sure you are treating them for parasites effectively! ♥️♥️♥️♥️

19- 28% of goat caretakers in Australia had a faecal egg count done on the day of drenching, then 14 days later. 💩🪱

This is necessary for determining if your treatment actually works!

Have a quick read on how to perform a f***l egg count reduction test aka "drench" test for the next time you treat your goats. (Or, ask your local vet to do it for you 😄🩺)

When treating for parasites, make sure you get a prescription from your veterinarian! 📝

35% of goat caretakers in Australia received a written prescription from a veterinarian for an anthelmintic/"drench" drug.

THIS IS A LEGAL REQUIREMENT 😏

What to expect when you're expecting ...? 😍🌹 Make sure its not worms! 🪱

19% of study participants started supplementing extra protein or energy about two weeks before kidding.

If you have mamma goats, 🐐 please make sure they have enough protein and energy! This will boost their immune system and help prevent parasites. 😄

Buying new ? 😁😍

Make sure they haven't had issues with Barber's Pole Worm (BPW) or any of the drugs used for treatment! 😪

👉 29% of goat caretakers in Australia asked about the presence of confirmed or suspected "drench" resistance (a useless "drench").
👉 28% asked about previous BPW infection.
👉 24% inquired about potential BPW contact.

Think you are a master? 💯

You probably are... However, maybe you don't know about this!

47% of goat caretakers in Australia scored coat condition (from 1-3; where 2 is average quality).

Poor hair coat can be a sign found in goats with subtle haemonchosis (the disease caused by Haemonchus contortus aka "Barber's Pole Worm") ①.

This method, used in conjunction with other methods of gathering evidence for Haemonchus infections, can be a useful way to determine if your goats are suffering from this disease.

What's the evidence for anthelmintic/"drench" doses for ?

⚠️ 4.2.2. Goats ".... it is generally recommended that goats be administered 1.5 times the sheep dose of levamisole and 1.5–2 times the sheep dose for other anthelmintics...."

➡️17% of the Australian goat caretakers that participated in our research used Levamisole at 1.5 x the sheep dose.
➡️23% used Ivermectin at 1.5 x the sheep dose.
➡️12% used Benzimidazole at 2 x the sheep dose
➡️6% used Eprinomectin at 2 x the sheep dose.

18% of goat caretakers used an anthelmintic/"drench" drug that was tested to be > 95% effective using a faecal egg count reduction test. 💩

Are you ready for the next tip for your ...? 🤩🐐

52% of Australian goat caretakers in this study confirmed the storage requirements on the label of their anthelmintic/"drench" product were consistently being met (i.e., not exceeding the maximum temperature or exposed to light).

🧪 32% calibrated the dosing gun using a measuring cylinder.

30% regularly checked the dosing gun to confirm it was not broken/damaged. 😱

🌡️ 📦 Make sure you store your chemicals appropriately (at all times!), otherwise your treatments may fail. 😞

🚀 Want to maximise your and the effectiveness of your WHITE anthelmintics/"drenches"(benzimadazole/macrocytic lactone/closantel)?

15% of participants in this study reduced or restricted food 12-24 hours before treatment. 11% reduced or restricted food several hours after treatment. 🌿

This method leads to decreased transit time for digested food and increased contact time of the drug with the parasites.🪱

**NOT FOR PREGNANT/STRESSED ANIMALS OR WITH CLEAR DRENCHES (organophosphates or levamisole); DO NOT RESTRICT WATER!**

50% of study participants used a faecal egg count to select goats for anthelmintic/"drench" treatment. 💩

F***l egg counts, combined with FAMACHA (c), and body condition scores, are an evidence-based indicator to support targeted selective treatment with anthelmintics ①.

Goats that excrete a high number of trichostrongyle eggs (incl. Barber's Pole Worm) one time are likely to excrete a high number of eggs another time ②.
