Economic Impact of Ivermectin as Anthelmintic on Body Weight Gain of Goat in Bangladesh

Abstract

Background & Objective: Goat is an important livestock animal in Bangladesh. To count the efficacy of selective anthelmintic for their treatment effects on body weight gain in Black Bengal goats. A field experiment was conducted at Kotalipara Upazila in Gopalgonj district of Bangladesh. Materials & Methods: The study was performed during the time from December 2020 to February 2021. The goats were selected randomly for this experiment and divided into two equal groups (treatment group and healthy control group) where each group consisted 30 goats and irrespective to age and sex under same rearing and feeding managements. One injectable Ivermectin (0.2mg/kg body weight, Sub-cutaneous route) preparations (Injection Vermic^®, Techno Drugs Ltd. Bangladesh) were used for as treatment group. All goats were reared intensively and same feeding status. The efficacy of selected anthelmintic was recorded with measure live body weight from day 0 through day 14 and day 28 of the trial period. Results:  Overall live weight gain recorded was 0.14 kg in goats of healthy control group whereas 0.76 kg weight recorded in goats of treatment group. The net return obtained by the day 28 of experimental study was Tk. 186 in goats of treatment group as against a profit of Tk. 46 obtained in goats of healthy control group. Conclusion: The administration of Ivermectin has a clear beneficial impact on live body weight in goat. More detailed studies are needed to explain the current status of the efficacy of anthelmintics, which are widely used in different agroecologies, animal species and livestock management in Bangladesh.
