Objectives
Parasitic infections are major constraint of large ruminant production and causes colossal economic loss to dairy industry. Among these Toxocara vitulorum is most important infecting calves in tropical and subtropical climates. It is responsible for retarded growth, low productivity and increased susceptibility of animals to other infections. Present study was accomplished to evaluate the comparative efficacy of herbal, oral and injectable anthelmintics against Toxocara vitulorum infestation in Nili-Ravi buffalo calves.
Material & Methods
For this 24 buffalo calves positive for T. vitulorum were randomly divided into 4 groups of 6 viz. A, B, C and D. Calves in group A were treated with Albendazole at 10 mg/ kg PO while the calves in group B were given Levamisole at 8 mg/kg PO. The animals in group C were treated with Doramectin at 0.2 mg/ kg SC whereas calves in group D were given Chenopodium album (herb) 2g/kg PO. All the treatments were given once. Eggs per gram (EPG) of calves in each group was determined at days 0 (pre-treatment) and then at day 4, 7, 14, and 21 (post-treatment). Efficacy of particular treatment was calculated on the basis of fecal egg count reduction test (FECRT).
Results
At day 4 (post-treatment), fecal egg reduction in groups A, B C and D was 59.67%, 48.79%, 39.82% and 1.82%, respectively. At day 7, fecal egg reduction in groups A, B C and D was 98.43%, 82.50%, 73.0% and 3.5%, respectively while at day 14 fecal egg reduction was 100.00 %, 98.25%, 95.95% and 6.7% in groups A, B, C and D, respectively. While 100.00% fecal egg reduction was recorded in group A, B and C on day 21 (post-treatment).
Conclusion
It was concluded that oral wormers ( albendazole, levamisole) and injectable wormers (doramectin) are equally effective in treating T. vitulorum infestation in buffalo calves while Chenopodium herb is not effective to treat T. vitulorum in buffalo calves.
