ABSTRACT

To evaluate the effects of ticks on blood parameters and efficacy of different drugs on controlling tick’s infestation in commercial layer, a double blind randomized controlled trial was conducted. For therapeutic trials, the 80 birds (n= 60 infested with ticks, n= 20 healthy birds) were selected and divided into four groups (A, B, C and D), each comprising of 20 birds. Group A and B were treated with Ivermectin @ 0.2mg/Kg orally for two days and Fipronil (Spray at once), respectively. Group C was kept as positive control whereas the ticks free birds were kept in group D. The results showed the significant decrease (p<0.001) in tick’s count in both the groups (A and B) as compared to group C. The efficacy of Ivermectin and Fipronil, on 28th day was 93.93% and 77.83%, respectively. Hence, the results proved Ivermectin to be more effective than Fipronil. The 40 birds (n=20 tick infested birds, n=20 healthy birds) were selected for haematological study. The results showed a significant decrease (p < 0.05) in the values of PCV (%), Hb concentration (gm/dl) and RBCs during tick infestation.
