How To Drench Sheep?
What does it mean to drench sheep? “Drenching” refers to the process of delivering oral deworming medication. Drenching sheep is a fairly straightforward process, but you must be careful and thorough to avoid accidentally hurting the sheep.
What age do you drench sheep? If your sheep are for breeding, a drench around 4 weeks before lambing should see the ewe through the stress periods of late pregnancy and lamb raising. Lambs should be drenched a week or two before weaning.
Why is drenching done in sheep? Sheep can be drenched at critical times with the aim of preventing the carry-over of worms from one season to the next. Drenching stops the contamination of pasture with worm eggs, so preventing the build-up of large populations of in- fective larvae on pastures.
Ivomec (ivermectin) sheep drench is the preferred and primary product used to deworm sheep by most shepherds. It treats adult and fourth-stage larvae of gastrointestinal roundworms, lungworms, and all larval stages of nasal bots.
Ewes should only be wormed once a year at lambing time; this will reduce the number of eggs on the pasture so that there are less for lambs to pick up. Lambs have little resistance to worms in their first grazing season but this develops with time.
You can be creative with administering Garlic Juice to Sheep: Garlic and garlic juice is know in many countries to be an excellent dewormer. It is administered to sheep in many creative ways: Added to kelp, added to dry feed, mixed with molasses and salt, mixed with bread-molasses-milk and salt, etc.
Ivermectin Sheep Drench is formulated only for administration to sheep; do not use in other species. The recommended dose level is 3 mL of Ivermectin Sheep Drench, containing 2400 mcg ivermectin, which is sufficient to treat 26 pounds of body weight.
Levamisole is a short acting clear drench. Levamisole is still highly effective against barber’s pole worm and Nematodirus on most properties. Nematodirus is often a problem after drought or in lambing paddocks as the egg is resilient and can survive in hot, dry conditions for long periods.
A typical sign of a worm problem is unthrifty sheep. An unthrifty sheep is one that is not eating properly, is losing condition, tends to lag behind the mob when moved and, in severe cases, is clearly weak. A worm problem often (but not always) results in sheep scouring and becoming daggy.
Valbazen Suspension (11.36 % or 113.6 mg/ml): 7.5 mg/kg orally; approved in sheep with meat withdrawal time of 7 days. Do NOT use in pregnant ewes in the first trimester of pregnancy. Safe-Guard/ Panacur Suspension (10% or 100 mg/ml): Note that SafeGard is not approved for use in sheep.
Underdosing is one of the major causes of increasing anthelmintic resistance. Flocks should be divided into groups for deworming or drenching equipment should be calibrated for the heaviest animals in the group. Oral drenching is the recommended method of treatment for sheep.
Tapeworm infestations. While segments of tapeworms are often seen in the faeces of growing lambs in the UK they exert no adverse effects on growth rate and treatment is not usually considered necessary. The use of group 1-BZ wormers in lambs will remove tapeworm infection.
Cydectin Oral Drench for sheep contains moxidectin. It is a wormer for both ewes and lambs. Cydectin for sheep has persistent activity against key sheep parasites. It provides up to 35 days of persistent protection against both Haemonchus and Teladorsagia worms.
Normally sheep should be treated every three to four weeks. Keep in mind that worms may develop resistance to a drug if exposed frequently. Lower stocking rates will reduce the intensity of the deworming program. Fewer sheep result in fewer shed worm eggs within a given area, and thereby reducing parasite loads.
Merial has launched Eprinex Multi 5mg/ml Pour-on for Beef and Dairy Cattle, Sheep and Goats, the first licensed, zero milk withdrawal, pour-on worm control product to be made available to sheep and goat dairy producers.
SHEEP AND GOATS
Administer DECTOMAX® injectable solution at a dosage rate of 200 µg/kg doramectin (1 ml/50 kg) body mass or for sheep only 300 µg/kg doramectin (1,5 ml/50 kg) body mass.
Fortunately, lambs begin to build up resistance at around three months of age and by six months most are well able to resist infection. As ewes are immune to these worms they do not carry any adult worms and so do not re-infect the pasture.
There are many different types of worms that can cause problems to sheep, but stomach worms are the most common. Stomach worms cause many symptoms in sheep and lambs including scour, weight-loss, poor growth rates and can result in death if the symptoms go undetected.
– When worming sheep/lambs do not dose and move onto clean pasture: This will increase the proportion of resistant worm eggs on the pasture and therefore encourage resistance. – Quarantine all bought in sheep and then turn back onto dirty pasture after 24-48 hours.
Raw or Unpasteurised Apple Cider Vinegar for sheep and lambs is also rich in vitamins, minerals and trace elements, particularly potassium. Potassium is also important in treating mastitis. Apple cider vinegar for sheep and lambs is recommended if the forage they are on is particularly low in potassium.
Some of the most common home remedies for sheep that won’t eat include providing electrolytes, probiotics, fresh grass, beer, baking soda, B vitamins, dewormers, and antibiotics. However, these are generally for minor conditions. For more serious concerns, consult a veterinarian.
Higher producing ewes rearing more than one lamb will need a source of digestible undegraded protein (DUP), to support good milk yields. Soya bean meal or protected soya can be included in the ration for this purpose.
In sheep it takes about 11 days for ivermectin to drop below the detectable level in blood, whereas in goats this level is reached 4 to 5 days after administration. On the odd occasion farmers have seen the side effects of an ivermectin (macrolytic lactone) overdose.
Lambs must have 2 doses of vaccine, 4 to 6 weeks apart, to achieve full immunity. The first vaccination is given at marking, the second as above or at weaning. Adult sheep vaccinated as lambs require an annual booster.
