Adult sheep should be wormed 2-4 times a year, more frequently if you notice your flock is thin or if you are not using an effective rotational grazing plan. What is this? I recommend rotating Ivomec with Safeguard or Cydectin.
CYDECTIN 0.1% Oral Drench for Sheep gives optimal pasture protection against stomach worms Teladorsagia sp and Haemonchus sp, with an 8 week dosing interval–i.e. 5 week persistent activity, plus a 3 week interval from any re-infection to the presence of eggs in the dung.
Cydectin Pour On for cattle is for the treatment of worms, lice and mange in all cattle. Short Meat Withold of 14 days. Long interdose interval of 8-10 weeks.
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.
It provides up to 35 days of persistent protection against both Haemonchus and Teladorsagia worms.
Secondly, worming every three weeks may work in the short term, but it will increase the risk of resistance in the mid/long term (plus you may be doing it more often than you need, hence wasting your money and time).
CYDECTIN ORAL prevents reinfection with Ostertagia spp and barber's pole worm (Haemonchus contortus) for at least 14 days. It prevents pasture contamination by Ostertagia spp eggs for at least 35 days and barber's pole worm (Haemonchus contortus) eggs for at least 30 days.
Overdosing sheep or lambs with drench or incorrect pre or post drenching management can be fatal so it is important to consider how you drench as well as 'when' and 'what with'. Key drenching principles include: Always read the product label for both dosage and safety information.
Signs include scours/diarrhoea, soiled tails or pale gums. Worm infestations can result in a failure to thrive and, in more serious cases, cause death. Sheep in particular may fail to move about in the wet conditions, resulting in a considerable build-up of worms in a short period of time.
A worming treatment every three months is usually enough to prevent problems from developing. It may be necessary to deworm your dog slightly more regularly if they scavenge a lot. Remember to protect your dog against lungworm as well as intestinal (gut) worms.
Most pour-on and injectable drenches only last 14-42 days.
ADMINISTRATION: CYDECTIN Oral Drench is ready-to-use. Administer 1 mL per 11 lb (1 mL per 5 kg) body weight into the mouth of the sheep, using any standard drenching equipment. Check dose rates and equipment before drenching. Do not overdose.
Persistent Protection Period
The persistent activity of CYDECTIN POUR-ON FOR CATTLE & RED DEER prevents the development of viable cattle tick (Rhipicephalus (Boophilus) microplus) for 21 days after treatment.
B - Keep them off pasture for 24-48 hours so that all the worm eggs have been passed.
By including all round higher levels of nutrients than similar products and recommending drenching every 4-6 weeks Pre-Tupping may help to maintain the wellbeing of ewes, lambs and tups, thus ensuring optimum performance.
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.
Dry conditions force parasites to stay at the base of the plants where they are less likely to be consumed by the livestock. Sheep (and goats) are generally not affected by the same internal parasites as cattle and horses.
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.
Is Cydectin the Same as Ivermectin? No, Cydectin and Ivermectin are definitely not the same. Ivermectin is the active ingredient in several dewormer products for cattle, swine and other animals. Cydectin products contain an active ingredient called moxidectin, which is part of the milbemycin chemical group.
SCOPS - Sustainable Control of Parasites in Sheep
- 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.
Closantel kills virtually all haemonchus larvae for at least four weeks after drenching and moxidectin (Cydectin®, Moximax®, Moxitak®, Sheepguard®, Topdec®) for at least two weeks. Moxidectin is also available in a long acting form that will give protection for 91 days (Cydectin LA ®, Mxaximus®).
While there is some degree of shared resistance between the avermectins (ivermectin, abamectin, doramectin, eprinomectin) and Cydectin, many scientific studies show that Cydectin is more effective than the avermectins when resistance is present.
Worms can live in the sheep's gut for many months. Some species can live exposed on the ground for six months or longer in favourable conditions. Black scour worm is the most common type of internal parasite causing infection in Australian sheep flocks.
Be aware: You can worm your dog too often
And it has no obvious benefit. In fact, over-worming your dog can actually backfire, and make your dog build up a tolerance – you most certainly don't want that.
If the WEC is high, you should promptly drench every sheep in the mob. If the mob will not be moved to a low-worm-risk paddock after drenching, consider scheduling a second drench in six weeks.
