Growth performance and chemical composition of Cirrhinus mrigala (mori) under the effect of chromium chloride hexahydratre
Main Article Content
Abstract
A nutritional trial was conducted for 90 days to investigate the effect of different levels of chromium chloride hexahydrate on Cirrhinus mrigala growth and body composition using two types of corn (gelatinized and non-gelatinized). Six test diets were prepared using three levels of chromium chloride hexahydrate (0.0, 0.2 and 0.4 mg kg-1). Fifty Cirrhinus mrigala fingerlings were distributed randomly among six groups each group each with two replicates. The result showed that Cirrhinus mrigala fed on gelatinized corn diet with 0.2 mg kg-1 chromium chloride hexahydrate showed maximum growth as compared to non-gelatinized corn. In case of body composition results revealed that fish fed on gelatinized corn with 0.4 mg kg-1showed maximum deposition of dry matter, crude fat, crude protein and gross energy while ash retention was observed maximum in non-gelatinized corn with 0.2 mg kg-1. It is concluded and suggested for Cirrhinus mrigala that gelatinized corn and chromium chloride hexahydrate in fish diet are very effective in growth and body composition.
