Field trial with the coccidiostatics metichlorpindol and robenidine in a rabbit farm
Abstract:
The effect of metichlorpindol and robenidine in broiler rabbits was examined. Administration of 125 ppm metichlorpindol did not reduce mortality and oocyst output significantly. In comparison with unmedicated rabbits, weight gain of metichlorpindol medicated rabbits was 4.76% lower after seven seeks of treatment, whereas feed conversion was improved by 1.87%. There was no effect on the production index. Medication with 33 and 66 ppm robenidine resulted in a significant reduction of mortality and oocyst output (0.05 > P > 0.01). The effect on oocyst reduction became already significant after two weeks of treatment. After four weeks both robenidine medicated groups gained significantly (0.05 > P > 0.01) more weight than metichlorpindol medicated and non medicated rabbits. After seven weeks of medication only the 66 ppm medicated group gained significantly (0.05 > P > 0.01) more weight than the 125 ppm metichlorpindol medicated group. In comparison with non medicated rabbits weight gain was 3.46% better. Feed conversion was improved by 6.76 and 6.55% at 33 and 66 ppm levels respectively, while the production index was improved by 19% and 22% respectively in comparison with non medicated and metichlorpindol medicated rabbits.
Insights
Robenidine significantly reduced mortality and oocyst output in broiler rabbits, improving weight gain and feed conversion. Metichlorpindol showed minimal benefits, with reduced weight gain and only slight feed conversion improvements.
Area of Science:
- Veterinary Parasitology
- Animal Science
- Poultry Health
Background:
- Coccidiosis is a significant parasitic disease in broiler rabbits, impacting production efficiency.
- Anticoccidial drugs are crucial for managing coccidiosis and improving animal welfare.
- Metichlorpindol and Robenidine are commonly used anticoccidial agents with varying efficacy.
Purpose of the Study:
- To evaluate and compare the efficacy of Metichlorpindol and Robenidine in controlling coccidiosis in broiler rabbits.
- To assess the impact of these medications on key production parameters such as mortality, oocyst output, weight gain, and feed conversion.
Main Methods:
- Broiler rabbits were administered varying concentrations of Metichlorpindol (125 ppm) and Robenidine (33 and 66 ppm).
- Control groups received no medication.
- Key performance indicators including mortality rates, oocyst shedding, body weight gain, feed conversion ratio, and production index were monitored throughout the study period (seven weeks).
Main Results:
- Metichlorpindol (125 ppm) did not significantly reduce mortality or oocyst output, and resulted in a 4.76% decrease in weight gain, though feed conversion improved by 1.87%.
- Robenidine (33 and 66 ppm) significantly reduced mortality and oocyst output (P < 0.05).
- Robenidine groups showed significantly improved weight gain (3.46% better than controls) and feed conversion (6.55-6.76% improvement) compared to both control and Metichlorpindol groups, leading to a 19-22% improvement in the production index.
Conclusions:
- Robenidine demonstrates superior efficacy over Metichlorpindol in controlling coccidiosis in broiler rabbits, significantly improving survival rates and production parameters.
- Metichlorpindol offers limited benefits and may negatively impact weight gain.
- Robenidine is a more effective anticoccidial agent for broiler rabbit production, enhancing overall efficiency and animal health.
