ROLE OF VITAMIN E IN GROWTH OF AN INDIAN MAJOR CARP, CATLA (CATLA CATLA)

Abstract

A feeding trial was conducted to study the role of vitamin E in
growth of Catla catla fry. Newly hatched larvae of Catla were fed
with synthetic diet, supplemented with 'graded levels of vitamin E @
0,50,100,150,200,250 mg per Kg of diet. The spawn were fed with five
times of their body weight for 30 days. Observation were made on the
basis of survival, growth, daily weight gain and food conversion ratio.
The significant weight gain and highest survival could be achieved by
the diet supplemented with 150 mg of vitamin E per kg of the diet. The
weight gain per day in 0, 50, 100, 150, 200 and 250 mg vitamin E/kg
supplemented diet were 4.0, 5.2, 6.5, 7 .8, 6.8, and 6.3 mg, while survival
was 50, 51.8, 52.4, 52.8, 52.2, and 52% respectively.
