    COMPARATIVE EFFICACY OF ATA (Annona reticulata) LEAF EXTRACTAND IVERMECTIN AGAINST ECTOPARASITES IN GOAT
    (Dept. of Pharmacology and Toxicology, 2014-12) RAHMAN, MD. RASHIDUR
    The research work was carried out for a period of 6 months from January to June, 2014 in the Department of Pharmacology, Sylhet Agricultural University, Sylhet and Sylhet Government Goat Developing Farm to evaluate the comparative efficacy of herbal drug Annona reticulata (English name: Custard apple and locally called ‘Ata’) solutions by spraying (7.5%, 15% and 30%) and Ivermectin against ectoparasitic infestation in goat. Twenty five goats of heavily infested with ectoparasites were selected and randomly divided into 5 equal groups (T0, T1, T2, T3 and T4) each group consisting of 5 goats. Goats of group T0 was kept as infected control. Remaining 4 groups i.e. T1, T2, T3 and T4 were treated with Annona reticulata (Ata) spray and Ivermectin respectively. The efficacy of Ata (Annona reticulate) leaf extract at 7.5 %, 15 % and 30 % were at 62 %, 67 % and 75 % respectively against ectoparasites in goat whereas the efficacy of Ivermectin was 100%. The pre-treatment (0 day) mean values of TEC (8.20±.035, 8.12±0.018, 8.25±0.020, 8.3±0.014, and 8.15±0.017), PCV (30.60±0.017, 30.49±0.028, 30.55±0.018, 30.7±0.035 and 30.3±0.065) and Hb (6.79±0.032, 7.45±0.020, 7.35±0.020, 7.2±0.029 and 7.25±0.018) were in the control and treated groups of T1, T2, T3 and T4 respectively. On the 28 day of the post-treatment, the mean values of TEC, PCV and HB were significantly (p<0.01) decreased upto TEC (7.7±0.031), PCV (29.5±0.038) and Hb (6.74±0.023) in the control groups but were significantly (p<0.01) increased upto TEC (9.38±0.023, 9.88±0.023, 10.43±0.021 and 11.2±0.038), PCV (31.18±0014, 31.33 ±0.024, 31.65 ±0.035 and 31.51±0.030) Hb (8.15±0.018, 8.27±0.023, 8.37±0.024 and 8.69±0.028) in the treated group of T1, T2, T3 and T4 respectively. The pre-treatment (0 day) mean values of TLC (7.2±0.037, th 7.28±0.146, 7.58±0.0.085, 7.96±0.170 and 8.46±0.140) and ESR (0.6±0.035, 0.25±0.018, 0.22±0.014, 0.2±0.017 and 0.28±0.0.020) were in the control and treated groups of T1, T2, T3 and T4 respectively. On the 28 day of the post-treatment, the mean values of TLC were significantly (p<0.01) increased upto TLC (7.58±0.082) and ESR (0.83±0.015) in the control groups but were significantly (p<0.01) decreased upto TLC (7.11±0.063, 7.37±0.069, 7.7±0.022 and 8.03±0.129) and ESR (0.2±0.035, 0.15 ±0.018, 0.13 ±0.011 and 0.15±0.018) in the treated group of T1, T2, T3 and T4 respectively. In this experiment all the goats following Ivermectin injection and Annona reticulata (Ata) spray remained healthy, no adverse effects and goat’s appetite increased, growth and coat colour improved rapidly.
