Continuous worm control

  • Contains 2.11% pyrantel tartrate
CW is 2.11% pyrantel tartrate medicated pellets.

The manufacturer recommends dosing a horse with a larvacidal dewormer such as ivermectin or moxidectin before beginning administration of a daily dewormer, to help destroy existing larvae and adult parasites. They also recommend horses receive ivermectin or moxidectin once or twice per year to control bots and praziquantel once or twice per year to control tapeworms.

Ingredients: Dehydrated Alfalfa Meal, Wheat Middlings, Brewers Dried Yeast, Brewers Dried Grains, Natural and Artificial Flavors, and preserved with Propionic Acid.


Instructions for Use:
CW Continuous Wormer (pyrantel tartrate) is to be administered on a continuous basis as a top dress on the horse's daily ration. Feed at the rate of 1.2 mg pyrantel tartrate per pound of body weight per day. To achieve this dose administer 0.5 ounces of CW Continuous Wormer per 250 lb of body weight. CW Continuous Wormer should be administered for the entire period that the animal is at risk to internal parasites. Unprotected animals that have grazed may already have an established S. vulgaris larval infestation. Before administering CW Continuous Wormer, these animals should be treated with a therapeutic dose of a larvicidal product. Foals may be fed CW Continuous Wormer at such time when consistent intake of grain mix is occurring. This is generally between two and three months of age. CW Continuous Wormer may be used in mares at any stage of pregnancy or lactation. Stallion fertility is not affected by the use of CW Continuous Wormer.

    CW is rated 4.8 out of 5 by 136.
    Rated 4 out of 5 by from She likes it!!! What a great decision!!! Easy feeding, no trips to the feed store for supplements, I don't even have to think about it!!! And the horses love it!!

    Rated 5 out of 5 by from So easy I love feeding Smart Pak to my entire barn. CW is the perfect daily dewormer
    Date published: 2016-02-03
    Rated 5 out of 5 by from Wonderful Product I purchased CW for my mare who gets colicky with the barometric pressure changes. Ever since I started her on this supplement, she has not had any more colicky tendencies which puts me at extreme ease knowing she's happy and healthy.
    Date published: 2015-09-23
    Rated 5 out of 5 by from Does the job. Our whole barn uses this daily wormer. When I moved there, I had never heard of daily pelleted wormer, but was relieved. My girl is almost impossible to medicate, and worming with paste/gel was a nightmare. We have fecals done regularly on the horses, and not one has been positive for worms. It works!
    Date published: 2015-05-16
    Rated 5 out of 5 by from Too soon to tell I have been feeding this product to my horses for about two months and will have a fecal check done next month. My husband insists that he doesn't want a manure pile and spreads the manure in our only pasture on a daily basis, so this product is tailor made for us.
    Date published: 2015-05-16
    Rated 5 out of 5 by from No more little worms! My mare came with a worm problem and no birds to control the population. We started on Equi-aid CW and two months later I can see the difference. Bloom in her coat and a much nicer figure. I wish it were that easy for us humans!
    Date published: 2014-09-30
    Rated 5 out of 5 by from Picky eater approved! Got a new horse that had not been in a routine worming program. Helped get the parasites in control and no problems eating it.
    Date published: 2014-08-07
    Rated 5 out of 5 by from Very good I bought this for a one month use this time. Since the drought has been on going here I decided to use this for a one time month de-wormer program to start my program off this year. It was easy and I felt better with it rather than a one week of paste wormer.
    Date published: 2014-05-14
    Rated 5 out of 5 by from Affordable I switched from Strongid to CW because it is the same product for less money.

    Rated 5 out of 5 by from Easy to feed horses readily eat this pellet, started 16 horses on it with no problems.

    Rated 5 out of 5 by from Great Product I love the peace of mind knowing my horses are protected with daily wormer.
    Date published: 2013-08-26
    Rated 2 out of 5 by from Regular deworming is cheaper and better If you regularly paste worm your horse and do fecals tests with the vet you will save yourself money in the long run as well as not putting the additional chemicals into your horse. I was forced to use the daily wormer for an insurance policy that said I must follow my vets suggestions for parasites. Changed vets and have discontinued the product.
    Date published: 2013-07-15
    Rated 5 out of 5 by from He likes the flavor. I am new to pelleted wormer. I think he likes the taste and consistency of the CW wormer pellets.
    Date published: 2013-06-12
    Rated 5 out of 5 by from purchase every year! I have been using a feed thru wormer for 5 years. I enjoy the confidence that I am providing the best protection against worm infestation. It is easy to remember, just add once a day to their feed, no need to remember what paste I used last, what month I last wormed my horses, did they get the whole dose. I haven't had an issue with my horses eating it right along with their regular feed.
    Date published: 2013-06-06
    Rated 2 out of 5 by from Would be great if it controlled parasites. I kept my warmblood on this for years and she looks fantastic but I recently took some TBs from the track and started them on CW as well, but after 3 months I did a fecal on them to determine what other paste wormers I should use, because they were not gaining weight. Their parasite loads were still through the roof. Dropped this in favor of a PowerPac and Ivermectin protocol. Everyone ate it happily, and I swear it gives them a shiny coat, but it just wasn't doing any good.
    Date published: 2013-05-20
    Rated 5 out of 5 by from Great product Could not keep weight on my 7yo paint gelding, he was eating so much grain, his coat was dull and long, and he was sluggish. He got all the routine pastes but is on 40 acres with 15 other horses that dont get regularly wormed. I got this and within a week you could see an improvement in his coat and weight. He continued to flourish and i put my yearling and 3yo on it as well. they dont even need grain in the winter. Everyone should use this product, you will seriously see a drastic improvement in your horse
    Date published: 2013-05-19
    Rated 5 out of 5 by from I have always used paste dewormers as I was concerned about the possibility of having a resistance issue with worms. Then I bought my current horse who I was told is allergic to paste wormers. After speaking with my vet, I decided to try him on this continuous wormer. Four years later it is still working great. He is one of the only horses at my barn that is having no issues with worms!

    Rated 5 out of 5 by from Peace of Mind I have miniature horses and it is important to me that they stay healthy and colic free. I love these products and dealing with the personel at Smart Pak has been a pleasure too. It gives me some peace of mind to know that the minis digestive systems are receiving some great care.
    Date published: 2013-03-01
    Rated 5 out of 5 by from old standby I've used this product for years and years. It's great for horses who are experts at spitting out paste wormers, and no one has refused it yet. And the price is the best of all the continuous wormers of similar chemical.
    Date published: 2013-02-25
    Rated 5 out of 5 by from trying I just started using this product. I have a 6 year old show horse who has had 3 neg. fecal labs prior to beginning. Just wanted to make sure we did not have a lot of worms before starting. I am using this only on my show horse as she is under more stress and I want to see if this will really help her with feed utilization and overall condition. The mare is a dressage horse (2nd level) and lower level (training level) event horse. Will see how it goes.
    Date published: 2013-02-01
    Rated 5 out of 5 by from Don't go without it This is one of those products that you don't readily see the benefits of till you quit using it. I've had my horses on it for years, but when I moved recently, I took them off of it in an effort to cut cost. It took a while, but I saw a difference in the quality of their hair coat & found that I needed to feed more grain in order to maintain weight. Needless to say, put them back on it. Hair coat quality has come back & have been able to reduce the amount of grain being fed.

    Date published: 2012-02-06
    Rated 5 out of 5 by from Works great I have a 9 horse boarding facility so I like to keep everyone on daily wormer to keep my pastures free of parasites. This product works very well and Smart Pak has the best price and with free shipping its a no brainer!
    Date published: 2012-01-17
    Rated 5 out of 5 by from Daily worming is the way to go! Have used this product for many years. It has made our unthrifty horses gain or maintain good weight and health. One colicky horse stopped having his monthly colic attacks. Well worth the savings in hay, grain and vet bills.
    Date published: 2012-01-07
    Rated 5 out of 5 by from Great Product I started using this with my horse when I moved her to the barn I was working at. They have their horses on this product and I think daily worming is a good idea. She has been on this wormer for a year now and has never had any issues. Always eats the pellets no problem.
    Date published: 2011-12-19
