ABSTRACT
Unavailability of probiotics in fish digestive system fingerlings is unable to digest and absorb their food properly. The current research was conducted to investigate the influence of probiotics added Linseed meal based (LMB) diet on hematology and carcass composition of Labeo rohita juveniles. Hematological parameters are essential diagnostics used to estimate the health status of fish. The usage of probiotics for fish health improvement is becoming common due to the higher demand for environment-friendly culture system in water. Linseed meal was used as a test ingredient to prepare six experimental test diets by adding probiotics (0, 1, 2, 3, 4 and 5 g/kg) and 1% indigestible chromic oxide for seventy days. According to their live wet weight, five percent feed was given to fingerlings twice a day. Fish blood and carcass samples (Whole body) were taken for hematological and carcass analysis at the end of the experiment. The highest carcass composition (crude protein; 18.72%, crude fat; 8.80% and gross energy; 2.31 kcal/g) was observed in fish fed with test diet II supplemented with probiotics (2 g/kg). Moreover, maximum RBCs number (2.62× 106mm-3), WBCs (7.84×103mm-3), PCV (24.61), platelets (63.85) and hemoglobin (7.87) had also been reported in the fish fingerlings fed on 2 g/kg of probiotics supplemented diet. Results indicated that probiotics supplementation has a critical role in improvement of fingerlings' body composition and hematological indices. Present findings showed that probiotics supplementation at 2 g/kg level in linseed by-product-based diet was very useful for enhancing the overall performance of L. rohita fingerlings.
RESUMO
A indisponibilidade de probióticos em alevinos do sistema digestivo de peixes faz com que ele seja incapaz de digerir e absorver seus alimentos adequadamente. A presente pesquisa foi conduzida para investigar a influência de probióticos adicionados à dieta à base de farelo de linhaça (LMB) na hematologia e na composição da carcaça de juvenis de Labeo rohita. Os parâmetros hematológicos são diagnósticos essenciais usados para estimar o estado de saúde dos peixes. O uso de probióticos para a melhoria da saúde dos peixes está se tornando comum devido à maior demanda por sistemas de cultivo em água que não agridam o meio ambiente. Farinha de linhaça foi usada como ingrediente para preparar seis dietas de teste experimentais adicionando probióticos (0, 1, 2, 3, 4 e 5 g/kg) e 1% de óxido crômico indigestível por 70 dias. De acordo com seu peso úmido vivo, 5% de alimento eram dados aos alevinos duas vezes ao dia. Amostras de sangue e carcaça de peixes (corpo inteiro) foram coletadas para análise hematológica e de carcaça no final do experimento. A maior composição da carcaça (proteína bruta, 18,72%; gordura bruta, 8,80%; e energia bruta, 2,31 kcal/g) foi observada em peixes alimentados com a dieta teste II suplementada com probióticos (2 g/kg). Além disso, os números máximos de RBCs (2,62×106 mm-3), WBCs (7,84×103 mm-3), PCV (24,61), plaquetas (63,85) e hemoglobina (7,87) também foram relatados em alevinos alimentados com 2 g/kg de dieta suplementada com probióticos. Os resultados indicaram que a suplementação de probióticos tem um papel crítico na melhoria da composição corporal dos alevinos e índices hematológicos. As descobertas atuais mostraram que a suplementação de probióticos no nível de 2 g/kg em dieta à base de subproduto de linhaça foi muito útil para melhorar o desempenho geral de alevinos de L. rohita.
