ABSTRACT
Abstract Ninety days study was conducted in hapas installed in earthen ponds. Fish of an average initial weight (220g) were evenly distributed in triplicate groups within fifteen hapas. Five experimental diets labeled as T1 (25% CP and NRC recommended amino acid level) as control diet, T2 (with 2% low protein and 5% amino acid supplementation), T3 (with 2% low protein and 10% amino acid supplementation), T4 (with 4% low protein and 10% amino acid supplementation) and T5 (with 4% low protein and 20% amino acid supplementation) were prepared. Fish were fed with @3% of their body weight twice a day at 10.00 & 1600 hour. Significantly higher percent weight gain (420.18 ± 66.84a) and specific growth rate (13499.33±1273.54a) along with improved feed conversion ratio (1.29 ± 0.09b) and hundred percent survivals were recorded during the trial. Furthermore proximate analysis of meat showed significant improvement in the crude protein level (81.77 ± 0.19a) served with diet containing 20% limiting amino acids mixture. Therefore, limiting amino acids can be a source of cost effective feed and use safely in L. rohita diet.
RESUMO
Resumo O estudo de 90 dias foi realizado em hapas instalados em tanques de terra. Peixes com peso inicial médio (220 g) foram distribuídos uniformemente em grupos triplicados em 15 hapas. Cinco dietas experimentais rotuladas como T1 (25% de CP e NRC recomendado nível de aminoácidos) como dieta controle, T2 (com 2% de proteína baixa e 5% de suplementação de aminoácidos), T3 (com 2% de proteína baixa e 10% de suplementação de aminoácidos), T4 (com 4% de baixa proteína e 10% de suplementação de aminoácidos) e T5 (com 4% de baixa proteína e 20% de suplementação de aminoácidos) foram preparadas. Os peixes foram alimentados com 3% do seu peso corporal duas vezes por dia às 10h00 e 16h00. Ganho de peso significativamente maior (420,18 ± 66,84a) e taxa de crescimento específico (13499,33 ± 1273,54a) juntamente com taxa de conversão alimentar melhorada (1, 29 ± 0,09b) e sobrevivência de cem por cento foram registrados durante o ensaio. Além disso, a análise aproximada da carne mostrou melhora significativa no nível de proteína bruta (81,77 ± 0,19a) servida com dieta contendo 20% de mistura de aminoácidos limitantes. Portanto, a limitação de aminoácidos pode ser uma fonte de alimentação econômica e usada com segurança na dieta de L. rohita.
