Effect of three growth promoters- Orgavit aqua, Aqua boost, and Megavit aqua on growth of Pangus (Pangasianodon hypophthalamus)

Abstract

A study was conducted to compare the efficacy and growth performance of Orgavit aqua from
“Organic Pharmaceuticals” on the growth of Pangus (Pangasianodon hypophthalamus) with other two
commonly used growth promoters Aqua boost and Megavit aqua from “Novartis Company”. The experiment
was done in the wet lab of Fisheries Technology Department, Bangladesh Agricultural University,
Mymensingh. A total 12 newly constructed aquarium and 200 fish were used for this study. The three growth
promoters were: used in separate nine (9) aquarium at recommended dose, lower dose, higher dose,
respectively. Three aquarium were used for the control (diet without any promoter). Pellet feed were used
with 10% body weight for each aquaria except control. Doses of, Orgavit-aqua were given as 1 mg, 3 mg and
5 mg/3 g feed/day, doses of Aqua-Boost were given as 1.0 mg, 1.7 mg, 2.0 mg/3.5 g feed/day and doses of
Megavit aqua were given as 1 mg, 3 mg, 5 mg/3 g feed/day. Water was exchanged regularly and artificial air
supplies were done continuously by aerator throughout the experimental period. The feeding trial period was
conducted for 21days. Among the three growth promoters Orgavit aqua from “Organic Pharmaceuticals”
showed better result at its recommended dose. On the other hand, Aqua-boost and Megavit aqua from
“Novartis Company” showed better result at their higher doses.
