Abstract

Seven substances, namely oxytetracycline (antibiotic), ethyloestrenol (synthetic
steroid), thyroid (hormone), alfalfa extract (plant material), glucosamine
(chemical), prawn shell (animal material) and testosterone (hormone), were
selected for evalution as growth promoting agents to add in the diet of the
prawn Penaeus indicus. These substances each was incorporated in a purified diet
consisting of casein, starch, sucrose, cod-liver oil, cholesterol, vitamins, minerals
and cellulose. The diets supplemented with testosterone, glucosamine, prawn shell
and alfalfa extract, respectively at levels 2.5 mg, 0.8 g, 0.8 g and 2.0 ml per
100 g of diet, produced faster growth, higher survival and better food conversion
ratio than the control diet did. Testosterone gave the best results, the other
substances in the order of efficiency being glucosamine, prawn shell and alfalfa
extract. The diets supplemented with oxytetracycline, ethyloestrenol and thyroid,
respectively at levels 10 mg. 0.5 mg and 1.0 mg per 100 g of diet, gave no
better result in growth, survival rate and food conversion ratio than the control.
Presenting the details ot the evaluation results, the effect of these seven substances
on the body composition of the prawns is discussed.
