Understanding Coccidiosis in Livestock
In the world of livestock health, coccidiosis presents a significant challenge. It is essential to understand the causes and impacts of this condition to make informed choices about preventative measures, such as using toltrazuril for cattle.
Causes of Coccidiosis
Coccidiosis in cattle is caused by a single-celled microscopic parasite that develops inside the intestinal cells of the infected animal. The infective form, known as the oocyst, is found in the feces of infected animals. Calves and lambs can become infected shortly after birth by ingesting feces from contaminated udders. The parasite can remain infective in the environment for weeks or months depending on the conditions (Producer.com).
| Coccidiosis Cause | Description |
| Parasite | Single-celled microscopic parasite that develops inside the intestinal cells |
| Transmission | Ingesting feces from contaminated udders |
| Environment | Parasite can remain infective in the environment for weeks or months |
Impact on Animal Health
In young calves with no previous exposure, the coccidia organism can multiply at remarkable rates. A single oocyst can potentially lead to the excretion of close to 30 million oocysts. Clinical signs in calves suffering from coccidiosis are usually a result of the damage to the intestinal cells caused by the parasite (Producer.com).

Interestingly, there was virtually no difference in weight gain between the group of treated calves and the group of untreated calves.
Toltrazuril’s efficacy extends to its metabolite, toltrazuril sulfone, which represents 100% of the total radioactivity in muscle and fat and 80% in the liver 8 days after the last administration, according to ScienceDirect. The same source confirms that the most appropriate marker residue for chickens and turkeys is toltrazuril sulfone, with established Maximum Residue Limits (MRL) for toltrazuril in poultry.
Comparison with Other Anti-Coccidial Drugs
When compared with other anti-coccidial drugs, toltrazuril has demonstrated superior efficacy. A study from PubMed Central compared the effects of toltrazuril (TTZ) and diclazuril (DCZ) in controlling intestinal coccidiosis in poultry and cattle. The results showed that, while both drugs had a positive effect, TTZ completely prevented oocyte excretion at a dosage of 15 mg/kg, while a higher dosage of DCZ (5 mg/kg) was required to reduce oocyte excretion significantly.
Furthermore, TTZ treatment resulted in significantly higher body weight gain compared to DCZ treatment and the control (untreated/infected) group, indicating improved productivity. Additionally, DCZ treatment and primary infection led to a decrease in CD4+ and CD8+ T cell populations in the spleen and mesenteric lymph nodes, suggesting immunosuppression during the infection. No reductions in T cell populations were observed in the TTZ-treated group.
In conclusion, toltrazuril for cattle stands out as a highly effective anti-coccidial drug, offering significant benefits in terms of controlling infection, improving animal health, and enhancing livestock productivity.
