You should drench sheep based on a targeted program using WormTests (fecal egg counts), not just a fixed schedule, to combat resistance, but key times often include a summer drench when pastures dry (Nov/Dec) and a weaning drench for lambs, with potential pre-lambing drenches for ewes, always using the right product at the right time, often rotating chemical groups, according to WORMTEST, Sheep Worm Test and WormBoss guidance. Over-drenching worsens resistance, so use testing to guide decisions.
U should worm your ewes 3 times a year, 2weeks before breeding, 2weeks before lambing when u go to padture. Lambs should be wormed at weaning then 30days should be good till u sell or if u put ewe lambs in flock u should worm then. and get on the 3 times a year.
Pale skin and eyes, bottle-jaw, weight loss, a tail in the mob, and deaths may mean that your sheep need drenching. If so, these signs occur well after production losses from worms are already occurring in the mob. WormTests give early warning of significant production losses.
Closantel (anthelmintic and flukicide) is available for sheep. Toxicity has been reported in sheep, goats, and cattle, at doses from 2.5x the recommended dose.
Failing to deworm frequently enough, deworming too frequently or deworming with ineffective medications are the most common mistakes.
Traditionally, most flocks have wormed ewes at lambing. This practice is designed to combat the drop in immunity to worms that ewes experience from around 2 weeks before lambing to 6 weeks afterwards.
Worms - The signs to look out for
A worm problem often (but not always) results in sheep scouring and becoming daggy. In severe cases, affected sheep may scour profusely. Other conditions can however produce these signs. Young sheep are far more susceptible to worms than older sheep.
Garlic – Use garlic as a worm-preventative and effective dewormer treatment. It aids in digestion and decreases worm counts. You can also mix garlic with molasses; try feeding it to them right out of your hand.
Research has shown that the efficacy of the white (BZ) and clear (AV) drenches can be improved by withholding food for 12-24 hours before treatment.
To minimize the risk of mild side effects (though they are rare), such as dull abdominal pain or nausea, it is advisable to take the medicine after breakfast. However, for optimal effectiveness in eliminating worms, it is recommended to take it either 2 hours after dinner or early in the morning on an empty stomach.
It is ideal for times when ewes and other sheep need a drench and vaccine at the same time. CYDECTIN EWEGUARD is highly effective against all major internal parasites that are susceptible to ML drench, including gastrointestinal roundworms and large lungworm.
Sheep become infected with worms when they graze. After they consume the infective larvae on the pasture, the larvae develop into adult worms and lay eggs inside of the sheep's digestive tract. The eggs are deposited on the pasture when the sheep poops.
The Don'ts of Colour Drenching
Selecting the wrong shade can make a room feel oppressive or uncomfortable. Overly bright or intense colours may overwhelm, while very dark hues can make a space feel smaller if not balanced with sufficient light.
Cydectin Long Acting Injection for Sheep contains moxidectin, a second-generation macrocyclic lactone. It is effective against sensitive strains of the following parasites and provides protection against severe challenges by Haemonchus contortus (barber's pole worm) for up to 4 months.
Salt and Lime: Another common practice is mixing salt and lime to create a loose lick. This provides a few basic nutrients, such as calcium and sodium. We also recommend adding Causmag, or Magnesium Oxide, to help with magnesium deficiencies – but only around lambing.
Pumpkins contain compounds like tannins, cucurbitine and phenols that have properties shown to have mild natural deworming properties. Studies have shown adding pumpkin seeds to a sheep's diet can reduce its overall intestinal parasite load.
Tapeworm segments can be seen in the feces of sheep and goats. They have a white, grain-like appearance. Adult worms, often up to a meter or more in length, can be expelled and passed in the environment. Tapeworm eggs can be seen in sheep and goat feces, using the standard worm count procedure.
Most often, the infection is caused by eating food or drinking water that is tainted with roundworm eggs. Ascariasis can cause symptoms such as stomach pain, vomiting, fever and cough. Serious health issues called complications can happen if many worms grow inside the body.
Animals with a very severe worm infection may not recover, despite receiving an effective drench, if the infection is too far advanced.
For best results in treating parasites, and to protect against potential resistance, sheep should be drenched between once and twice a year, depending on whether they are breeding or not. Based on the Australian climate, the first drench should be conducted in the summer season, usually around November or December.
Hold sheep off pasture for 24-48 hours, until any worm eggs present in the gut have passed out with the dung. Faecal egg count (FEC) sampling at least 10 sheep where possible, 14 days after treatment will show that the worming regime has worked.
