EFFECT OF LYKAMIN ON GROWTH AND BIOCHEMICAL COMPOSITION OF LONG WHISKERED CATFISH, MYSTUS GULlO (HAMILTON) FINGERLINGS UNDER LABORATORY CONDITIONS
37 / 16
Abstract
A growth trial was conducted to test the effect of Lykamin (dietary
supplement) on growth, survival and feed conversion in Mystus gulio. Four
isoproteic diets were formulated by incorporating the growth promoter,
Lykamin at the levels of 0, 0.25, 0.50 and 0. 75% diet. The crude protein
content was 30% in each diet. The diets were fed to triplicate groups of
catfish fingerlings twice daily at a level of 5% of the total body weight for
120 days. Regular fortnightly sampling was done to evaluate the growth
performance of the experimental animals. Water quality parameters during
the experimental period were maintained within the range suitable for catfish.
The results showed better specific growth rate, weight gain, protein efficiency
ratio and feed conversion ratio in the group which was given 0.75% Lykamin
diet.
