ABSTRACT
Fish protein is serving as a source of nutrition for protein starving world. However, sustainable aquaculture products require inexpensive plant by-products due to finite sources of fish meal. Therefore, this study was conducted to examine nutrient utilization, growth performance and hematological indices of Cirrhinus mrigala fingerlings fed on Moringa oleifera leaf meal (MOLM) based diets. Fish were fed with six isonitrogenous and isoenergetic diets having MOLM as a substitute of fish meal (FM) at the levels of 0%, 10%, 20%, 30%, 40% and 50% for the period of 90 days. Fingerlings having initial weight 6.35±0.04g were reared in triplicate tanks at the stocking density of 15 and hand fed at the rate of 5% of total biomass twice regularly. Chromic oxide inclusion level was 1% in diets. After analysis, maximum growth performance and improved digestibility of nutrients were found in fish fed with diet at 10% replacement level as compared to fish fed on control diet and other test diets. Additionally, it was found that the red blood cells, white blood cells, hemoglobin and mean corpuscular hemoglobin concentration of fish showed a significantly (p<0.05) inverse correlation with the increase in MOLM. In present research, it was concluded that MOLM has good potential to be used as a FM substitute in C. mrigala diet with maximum effect at 10% showing positive hematological indices.
RESUMO
A proteína do peixe está servindo como fonte de nutrição para o mundo faminto por proteína. No entanto, produtos de aquicultura sustentáveis requerem subprodutos vegetais baratos devido às fontes finitas de farinha de peixe. Portanto, este estudo foi conduzido para examinar a utilização de nutrientes, o desempenho do crescimento e os índices hematológicos de alevinos de Cirrhinus mrigala alimentados com dietas à base de farelo de folhas de Moringa oleifera (MOLM). Os peixes foram alimentados com seis dietas isonitrogênicas e isoenergéticas contendo MOLM como substituto da farinha de peixe (FM) nos níveis de 0%, 10%, 20%, 30%, 40% e 50% pelo período de 90 dias. Os alevinos com peso inicial de 6,35 ± 0,04g foram criados em tanques triplicados com densidade de 15 animais e alimentados à mão a uma taxa de 5% da biomassa total duas vezes regularmente. O nível de inclusão de óxido crômico foi de 1% nas dietas. Após análise, desempenho máximo de crescimento e melhor digestibilidade de nutrientes foram encontrados em peixes alimentados com dieta em nível de reposição de 10% em comparação com peixes alimentados com dieta controle e outras dietas teste. Além disso, verificou-se que as concentrações de hemácias, leucócitos, hemoglobina e hemoglobina corpuscular média dos peixes apresentaram correlação inversa significativa (p < 0,05) com o aumento do MOLM. Na presente pesquisa, concluiu-se que o MOLM tem bom potencial para ser utilizado como substituto do FM na dieta de C. mrigala com efeito máximo a 10% apresentando índices hematológicos positivos.
