Anthelmintics AKA Dewormers, Available Options & When To Use

Anthelmintics AKA Dewormers, Available Options & When To Use

There are numerous anthelmintics available for treating internal parasites. We stock multiple options that give you a choice in how they are administered and the type of parasite you need to target the treatment for.

When should you treat for internal parasites/worms? Many people do routine “worming” but this is not something we recommend, overuse of anthelmintics is leading to parasites developing resistance to available options, much like the issues caused by improper use and over use of antibiotics. Using broad spectrum anthelmintics can take a lot out of your animal, its not easy on their systems. If you see worms in your birds waste, you need to treat, if you have suspected issues we always recommend getting a fecal test done to determine if that is the issue the animal is having and if so, what parasite you need to treat for. MidAmerica Agricultural Research is fast and affordable, they test for all types of worms and coccidiosis. Other options include doing a fecal float yourself if you have a microscope or asking your vet to do one.

Here is the website for MidAmerica Agricultural Research.

Pantex Wormex, Pantex Wormex Tablets and Vet-Schroeder Tollisan Anti Worm cover treatment of just roundworm. Wormex is a powder and Anti Worm is a liquid solution, both are used by adding them to the drinking water. Two treatments is recommended with both these products. If you are positive you are dealing with roundworm these are great products as they are easy to use. The active ingredient is Levamisole and its works by paralyzing the roundworm and then it is excreted by your animal in their waste. 

Valbazen is a broad spectrum anthelmintic so It covers most internal parasites. It requires two rounds of dosing and it is a suspension. Suspensions cannot be added to drinking water as they will not properly disperse in the water. To administer Valbazen you need to weigh each animal needing treatment and calculate the dose for them based on weight. An oral syringe is used to measure the needed amount of product. It can be easier to saturate a small piece of bread with the Valbazen and offer it as a treat for that animal, rather than trying to dose them orally with the syringe. We don’t normally recommend feeding bread, its not a good treat choice, but if it gets the medicine down then its worth the occasional couple bites of bread, especially if you are not comfortable and confident with oral administration of medications, as aspiration is a risk.

MediwormPigeon Wormout Tablets and DAC Worm Tabs are broad spectrum anthelmintic options in tablet form you give each bird orally. Dosing should be done by weight with these tablets and two doses are required for a full treatment. If you just have a few birds to treat these are a good option, as is the Valbazen. Giving a pill to your animals vs an oral suspension can be easier for some animals and owners.

Vetafarm Pigeon Wormout Plus Tablets are a broad spectrum oral tablet option that also covers treatment of coccidiosis. This product is dosed for two consecutive days in Pigeons.

Moxivet Plus and Wormout Gel are broad spectrum anthelmintic products that mix into the drinking water. Both can also be used undiluted as a direct oral treatment. 

Moxivet Plus contains moxidectin, please carefully follow the directions and do not use more than once every three months as it has a very long half-life in birds. It is a good option when other products have been tried and the parasite problem persists. Moxivet Plus is effective on less common internal parasites such as gizzard worm and pinworm. In addition to treating worms, it is also used to treat air sac mites, feather mites, scaly face & leg mites.

Wormout Gel is a very popular broad spectrum anthelmintic in the cage bird and parrot fancy. It can be dosed directly or easily mixed in with drinking water. Wormout Gel is given for two consecutive days, if used in water it needs to be the only water available.

Wormer Deluxe Powder is a water soluble, broad spectrum anthelmintic product, that is a good choice when needing to treat a lot of birds. The product is mixed into their drinking water for two consecutive days, changed daily, as the only water source. The treatment course needs to be repeated in 21 days.

With all products a two week withdrawal after last treatment is best practice.

Feel free to send us a message if you have any other questions about these products!

Suspension vs. Solution & Why It Matters

Suspension vs. Solution & Why It Matters

Chemistry lesson on suspensions and solutions to help understand the use of medications.
For our purpose here solutions are an even dispersal of a medication or substance, like a powdered medication or a medication solution, in water, that results in a homogeneous mixture. With a solution there is an equal amount of the added product in each drink/dose. The products dispersement remains even over time, unlike a suspension. An example of a solution many of you are familiar with is Tiamulin (denagard). A water soluble powder that results in a homogenous solution is Cocci-Geel or Wormex.
 
Suspensions are medications that are heterogeneous, there for do not disperse evenly in water. If placed in water they will not evenly disperse, this means each drink or dose does not contain an equal amount of product, some drinks/doses may contain none. Examples of suspensions are Safeguard suspension and Valbazen suspension which people often recommend people add to water. These products DO NOT result in a homogenous solution. When using these products they must be shaken to evenly disperse the medication in the suspension before use. They are fine if measured out and each animal is dosed by weight orally.

Here is a good video that demonstrates the differences between suspensions and solutions. The video also mentions Colloids, an example of that many of you are familiar with is Colloidal Silver.

I hope this helps clear up the how and why products must be used in specific ways. Unfortunately, in the case of suspensions, the correct way is often not the easy way.

Trichomonas (Canker), Sour Crop & Vent Gleet, Part Two

Trichomonas Gallinae (Canker), Sour Crop and Cloacitis (Vent Gleet) Treatment - Part Two

Sour crop is a health issue that most bird keepers will encounter at some point while caring for birds. Sour crop can be caused by something as simple as eating long grass, hay or straw. Eating spoiled food matter, or being exposed to unsanitary water or waste from other animals that tend to be vectors for fungus/yeast, like waterfowl. Prevention is always best but despite good efforts the issue can occur. Trichomonas gallinae (Canker) can also cause crop stasis.

What is sour crop? 

Sour crop, also known as crop stasis is caused by yeast (candida albicans) aka thrush that is causing a thickening of the crop wall. This can be caused by factors such as exposure to yeast in what they ingest or due to a blockage from consuming matter that won’t exit the crop like long grass, straw or hay which will cause a yeast bloom in the birds crop over time. When suffering from sour crop birds loose condition, drop weight and often loose interest in food, often they will consume a lot of water, they are dehydrated because food and liquid is not exiting the crop and entering their digestive system.

How does it occur?

Birds must be able to pass what they eat through their crop and into the proventriculus and then on to the gizzard. The gizzard is where food is ground up, it functions similar to our teeth, the grit your birds ingest deposit in the muscle folds of the gizzard and help “chew” the food. Straw, hay and long grass often can’t exit the crop to make it to the gizzard and this causes sour crop. We strongly recommend not using straw or hay in your birds environment for this reason and keeping grass cut to just a few inches high that they have access too. Do not toss lawn clippings into your poultry runs either as this can cause impaction if they consume blades too long to pass. Pine shavings, sand, nesting mats, gravel are all options for where someone would use straw or hay in their setup. 

Another risk factor for sour crop is feeding young birds scratch grains, the whole grains are often difficult to pass through the crop and they may not have consumed enough grit to properly digest the grains which can lead to malnutrition issues. A nutritionally balanced crumble or small pellet is best for young chickens, ducks, guinea, turkeys and other poultry.

Antibiotics can be yet another reason for sour crop. Antibiotics are not very selective in what bacteria they kill so when they are used they kill off the bad AND good bacteria in the system. Disruption of healthy flora is disrupted by this and its a prime opportunity for yeast to bloom and overcome its host. It is STRONGLY recommended to start probiotic treatment for your birds after a course of antibiotics. We offer several probiotic options.

What can I do?

Important steps to prevention are making sure your birds water is clean, use fresh feed and be on the lookout for mold, and keep waterfowl separate from your chickens, turkeys, guinea fowl, pea fowl, etc. as they are often vectors for yeast because of how they interact with water. If you have a climate or housing situation where yeast is a concern you can use Acidified Copper Sulfate monthly in your birds waterers as a prophylactic measure. Acidified Copper Sulfate will help keep yeast count down but if you have a bird that’s crop is not emptying you need to treat them with medications and depending on what caused the blockage, oil and massaging the crop may help get things moving again. 

If you suspect a bird has sour crop feel to see if their crop is bloated or squishy, smell their breath and often when palpating the crop air will be expelled if the crop stasis is do to yeast because its fermenting in their crop. Isolate the bird you are concerned about and withhold food and water till the next morning (or evening if the issue was discovered early in the morning) the birds crop should be empty if its crop is functioning normally, if not you need to treat them.

Medicinal treatment options for sour crop due to yeast is nystatin and ketoconazole. If the cause of your birds crop stasis is trichomonas gallinae then nystatin and an antiprotozoal are a recommended combination. If there is a very foul smell then its likely trichomonas gallinae, if it smells yeasty then the cause it most like candida albicans (yeast). The only way to know what the cause is for sure is to have a lab test done at your veterinarian. If the cause is trichomonas gallinae we offer antiprotozoal options of metronidazole, carnidazole, secnidazole or ronidazole.

Trichomonas Gallinae (Canker), Sour Crop and Cloacitis (Vent Gleet) Treatment – Part One

Trichomonas Gallinae (Canker), Sour Crop and Cloacitis (Vent Gleet) Treatment - Part One

Trichomonas Gallinae, Sour Crop and Cloacitis are health issues that almost all bird keepers will encounter over time. All require treatment with medications to resolve the issue or the bird may die. We offer several medication options at Springwater Avian Health as well as Acidified Copper Sulfate which can be used as a preventative measure if your birds seem to be more susceptible to these health issues. Climate, weather, housing, feed and species all factor into the risk factors for these issues. It is always best to prepare in advance for these issues and keep medication on hand to tackle the issue as soon as it arises. For todays article we will focus on Trichomonas Gallinae (Canker).

Trichomonas Gallinae is a parasite that occurs in most all areas of the world and across multiple species of birds including pigeons, doves, raptors, chickens, turkeys, parrots, and finches. Trichomonas Gallinae can be a mild or severe infection, if left untreated a bird may not be able to fend off the effects of the parasite and succumb to it within 4-18 days. Transmission of the parasite usually occurs from contact with other birds, directly or indirectly through an infected parent feeding their young, contaminated drinking water, feces, saliva, crop secretions of other birds or for birds of prey, eating an animal/bird infected with the parasite.

Trichomonas Gallinae can present as small yellowish plaques on mucus membranes that grow over the duration of the infection,  they have ben described by some as cheese like and can become necrotic, often there is a very foul odor. The plaques are usually detected in the oral cavity or on the edge of the beak, the tongue and in the choana and can completely block a birds esophagus and trachea if left untreated. Virulent strains of the virus can affect the birds liver and gastrointestinal tract. Fecal matter of the bird may turn green and the urates bright yellow which indicates its internal organs are infected also.

Best course of treatment is an antiprotozoal medication accompanied by Nystatin. An antiprotozoal systemically attacks the parasite while the Nystatin works by direct contact with it. Combined this is a very effective treatment if started as soon as possible. Administer the appropriate dose by your birds weight of the antiprotozoal medication. Nystatin you can add to feed for the needed treatment duration but at the beginning of treatment making a slurry with water and applying it directly the lesions helps attack the parasite more rapidly, often when the illness is detected your bird wont have a very good appetite. Tube feeding/crop needling of the nystatin slurry would be beneficial if they are not eating or drinking.
