Unlocking the Potential: Toltrazuril for Strong and Resilient Goats

Anticoccidial Agent Overview

Toltrazuril is a triazinetrione derivative used as an anticoccidial agent. It is widely employed in the care of chickens, turkeys, pigs, and cattle to prevent and treat coccidiosis, a disease caused by protozoan parasites known as coccidia (ScienceDirect).

Administered through drinking water, toltrazuril is commonly used in Europe, Australia, and Canada for treating coccidiosis in various animal species, primarily birds and pigs. However, it is not registered for use in the United States.

In the context of ‘toltrazuril for goats’, it’s important to note that while toltrazuril is not approved for use in goats in the U.S., its metabolite, ponazuril, is approved for use in horses under the trade name “Marquis”.

Mode of Action

Toltrazuril has a coccidiocidal mode of action, meaning it acts by killing coccidia. It impacts all intracellular developmental stages of various genera of coccidia.

This medication is practically non-toxic for mammal hosts, making it a safe and effective treatment for coccidiosis in livestock. It interferes with the division of the parasite’s nucleus and the activity of the mitochondria, disrupting the coccidia life cycle and eventually leading to the death of the parasite.

Understanding the role and function of toltrazuril in livestock health management is essential for those interested in maintaining the health of their animals. However, it’s crucial to remember that the use of this drug is regulated differently in various regions, and it is currently not approved for use in goats in the United States.

Toltrazuril Usage and Effectiveness

Toltrazuril is a well-regarded anticoccidial agent used extensively for the prevention and treatment of coccidiosis in various species of livestock. Understanding its administration methods and the process of its metabolism and elimination can help optimize its use.

Administration in Different Species

Toltrazuril is a triazinetrione derivative that is widely used in chickens, turkeys, pigs, and cattle for the prevention and treatment of coccidiosis. It is typically administered in drinking water, making it a convenient and effective solution for livestock health management.

The agent works against both the merogony and gametogony phase coccidia, interrupting or significantly reducing oocyst secretion. This broad-spectrum effectiveness is one of the reasons why toltrazuril is considered a valuable tool in coccidiosis control. It affects all intracellular developmental stages of various genera of coccidia, and is practically non-toxic for mammal hosts (ScienceDirect).

Metabolism and Elimination

Understanding how a drug is metabolized and eliminated from a host organism is crucial for determining appropriate dosage and timing. For toltrazuril, it is eliminated from chickens and turkeys within 15.5 and 24 hours, respectively. Toltrazuril sulfone is the major metabolite in chickens (ScienceDirect).

This rapid elimination means that the impact on the host organism is minimal, while the effect on coccidia is potent and efficient.

SpeciesElimination Time
Chickens15.5 hours
Turkeys24 hours

In all, the use of toltrazuril in livestock, including potential applications in goats, offers a promising approach to managing coccidiosis. By understanding its administration, metabolism, and elimination, livestock owners can make the most of this powerful anticoccidial agent.

Toltrazuril Availability and Regulations

The availability and usage of toltrazuril vary widely across the globe, primarily due to differing regulations and approval processes for veterinary drugs. Let’s delve deeper into the global usage and registration of toltrazuril, as well as its restrictions in the United States.

Global Usage and Registration

Toltrazuril is registered and commonly used in Europe, Australia, and Canada for the treatment of coccidiosis in various animal species, primarily birds and pigs. Its effectiveness against this parasitic disease makes it a valuable tool in these regions for maintaining the health and productivity of livestock.

Despite its widespread use in these parts of the world, toltrazuril is not universally approved for all animals in all countries. For instance, in the United States, it is not registered for use, especially when it comes to goats.

Restrictions in the United States

In the United States, the use of toltrazuril for goats is not approved. It must go through the FDA nomination and evaluation process to gain approval as a finished drug. Toltrazuril was submitted for FDA approval by Wedgewood Pharmacy but was classified under a category that prevented it from entering the evaluation phase.

Only ponazuril, a metabolite of toltrazuril, has been approved for use in horses in the U.S. under the trade name “Marquis” (Backyard Goats).

This limitation in the approval of drugs for use in goats isn’t unusual in the United States. Currently, there are only 26 drugs approved and labeled for use in goats, so many drugs used for goats are “off-label” or “extra-label” (Backyard Goats).

In many countries, including the USA, treatments licensed for cattle and sheep are often used for goats due to the lack of licensed treatments specifically for goats. It is recommended to administer medications via drenching rather than through drinking water or feed for ill kids.

While the use of toltrazuril for goats may seem promising based on results in other countries, the lack of FDA approval for this usage in the United States poses a challenge for those seeking to leverage its anticoccidial properties for goat health. Nevertheless, understanding these regulations is crucial for anyone considering this treatment option.

Toltrazuril for Goats: The Controversy

The use of toltrazuril for goats remains a contentious topic, especially in the United States. Given its popularity among producers for combating coccidia in goats, the legal restrictions imposed on its use have generated significant debate.

Legal Issues in the U.S.

In the United States, the use, purchase, or sale of toltrazuril for goats is prohibited. The only approved use of a toltrazuril metabolite, ponazuril, is limited to horses under the trade name “Marquis” (Backyard Goats). The U.S. Food and Drug Administration (FDA) currently approves only 26 drugs specifically for goats. As a result, many goats in the U.S. are treated with “off-label” or “extra-label” drugs that are originally approved for cattle and sheep.

Toltrazuril was submitted to the FDA for approval as a finished drug by Wedgewood Pharmacy. However, it was classified under a category that precludes it from entering the evaluation phase.

Alternatives for Goat Coccidiosis

Given the legal restrictions on the use of toltrazuril for goats in the U.S., producers often turn to licensed treatments for cattle and sheep. These treatments are used off-label to address coccidiosis in goats.

The best approach is to administer medications to ill kids via drenching rather than through drinking water or feed. This method ensures that the medication is directly ingested by the goat, increasing its effectiveness (AppleJo Farms).

While the controversy surrounding toltrazuril continues, the focus remains on finding the best and most effective solutions for managing coccidiosis in goats. This includes not only exploring alternative treatments but also emphasizing preventive measures like maintaining cleanliness and controlling contamination within goat herds.

Treatment Protocols for Goat Coccidiosis

Treatment for coccidiosis in goats focuses on timely intervention and the right dosage of the anticoccidial agent. In this case, Baycox, which contains toltrazuril, is often used for successful treatment due to its effectiveness and ease of administration.

Baycox Dosage and Administration

As per the recommended dosage, goats should be treated with a single 1 mL dose of Baycox per 2.5 kg or 5.5 lbs. body weight. This dosage is specifically for treating coccidiosis and should be administered at 7-12 days of age to obtain maximum benefit before the onset of clinical signs caused by Eimeria ovinoidalis and Eimeria crandalis (AppleJo Farms).

Body Weight (kg)Dosage (ml)

The medication should be administered by drenching rather than through drinking water or feed, especially for ill kids. Since the plasma half-life of toltrazuril in lambs & kids is about 170 hours (approximately 5 days) after oral administration, with slow absorption from the gut and high fecal excretion, timely administration is crucial for effective treatment.

Timing and Benefits of Treatment

Considering the onset of clinical signs of coccidiosis typically occurs between 5–8 weeks of age, early treatment with Baycox is beneficial. Symptoms may include poor fecal pellet formation, decreased appetite, weight loss, and in severe cases, diarrhea with blood, tenesmus, and even death.

By treating kids at 7-12 days of age, the likelihood of symptom development reduces significantly. The treatment with Baycox not only helps in controlling coccidiosis but also contributes to overall goat health by preventing weight loss and improving appetite.

While there are natural products like Lespedeza cuneata in feed pellets which have shown to decrease fecal signs and oocyst counts in kids, relying solely on such natural products to prevent coccidiosis in very young kids is considered risky. Hence, a balanced approach involving the use of anticoccidial agents like toltrazuril, along with natural preventive measures, can help in managing goat coccidiosis more effectively.

Coccidiosis Symptoms in Goats

Understanding the symptoms of coccidiosis in goats is crucial for early detection and effective treatment. Early diagnosis can lead to more successful results when using treatments like toltrazuril for goats.

Nutritional SupportProviding extra nutritional support to help with dietary changes

Implementing these preventive measures can contribute significantly to maintaining the health and resilience of goats. It’s important to remember that while these measures can help prevent diseases, they are not substitutes for regular veterinary check-ups and professional care.

Di-Methox and Fecal Testing

The treatment for coccidiosis in goats often involves the use of over-the-counter drugs, such as Di-Methox, as well as diagnostic tests to confirm the presence of the disease. This section delves into the specifics of using Di-Methox for treatment and the role of fecal testing in diagnosing coccidiosis.

Treatment with Di-Methox

Di-Methox is an effective solution for treating coccidiosis in goats. The recommended dosage is 1cc per 5lbs on the first day, followed by 1cc per 10lbs on days 2 through 5. The drug is administered orally.

11cc per 5lbs
2 – 51cc per 10lbs

After completing the treatment, it’s advisable to give the goats oral probiotics. This helps support the proper function of the rumen, which is crucial for the overall health and well-being of the goats.

Importance of Fecal Testing

While treatment is an integral part of managing coccidiosis in goats, diagnosing the disease accurately is equally important. Diarrhea in kids, a common symptom of coccidiosis, does not always indicate the presence of coccidia. Therefore, fecal testing becomes necessary for definitive diagnosis.

Fecal testing involves collecting a sample of the goat’s feces and sending it to a lab for analysis. The lab identifies the type and number of parasites in the sample, which assists in determining the appropriate treatment protocol. Some recommended labs for fecal testing include Meadowmist Lab Service and MidAmerica Ag Research.

When combined with effective treatment, such as the use of Di-Methox, fecal testing allows for the accurate diagnosis and effective management of coccidiosis in goats. This combination is key in ensuring the health and productivity of the herd.

Remember, while Di-Methox is a commonly used treatment, it’s not the only option available. Alternatives such as toltrazuril for goats also exist and may be considered depending on the specific circumstances of each case. Always consult with a veterinarian to determine the best treatment option for your herd.
